A new object 52 file format can be supported simply by creating a new BFD back end and 53 adding it to the library. 54 55 BFD is split into two parts: the front end, and the back ends (one 56 for each object file format). 57 * The front end of BFD provides the interface to the user. It manages 58 memory and various canonical data structures. The front end also 59 decides which back end to use and when to call back end routines. 60 61 * The back ends provide BFD its view of the real world. Each back 62 end provides a set of calls which the BFD front end can use to 63 maintain its canonical form. The back ends also may keep around 64 information for their own use, for greater efficiency. 65 66 * Menu: 67 68 * History:: History 69 * How It Works:: How It Works 70 * What BFD Version 2 Can Do:: What BFD Version 2 Can Do 71 72 73 File: bfd.info, Node: History, Next: How It Works, Prev: Overview, Up: Overview 74 75 1.1 History 76 =========== 77 78 One spur behind BFD was the desire, on the part of the GNU 960 team at 79 Intel Oregon, for interoperability of applications on their COFF and 80 b.out file formats. Cygnus was providing GNU support for the team, and 81 was contracted to provide the required functionality. 82 83 The name came from a conversation David Wallace was having with 84 Richard Stallman about the library: RMS said that it would be quite 85 hard--David said "BFD". Stallman was right, but the name stuck. 86 87 At the same time, Ready Systems wanted much the same thing, but for 88 different object file formats: IEEE-695, Oasys, Srecords, a.out and 68k 89 coff. 90 91 BFD was first implemented by members of Cygnus Support; Steve 92 Chamberlain (`sac (a] cygnus.com'), John Gilmore (`gnu (a] cygnus.com'), K. 93 Richard Pixley (`rich (a] cygnus.com') and David Henkel-Wallace 94 (`gumby (a] cygnus.com'). 95 96 97 File: bfd.info, Node: How It Works, Next: What BFD Version 2 Can Do, Prev: History, Up: Overview 98 99 1.2 How To Use BFD 100 ================== 101 102 To use the library, include `bfd.h' and link with `libbfd.a'. 103 104 BFD provides a common interface to the parts of an object file for a 105 calling application. 106 107 When an application successfully opens a target file (object, 108 archive, or whatever), a pointer to an internal structure is returned. 109 This pointer points to a structure called `bfd', described in `bfd.h'. 110 Our convention is to call this pointer a BFD, and instances of it 111 within code `abfd'. All operations on the target object file are 112 applied as methods to the BFD. The mapping is defined within `bfd.h' 113 in a set of macros, all beginning with `bfd_' to reduce namespace 114 pollution. 115 116 For example, this sequence does what you would probably expect: 117 return the number of sections in an object file attached to a BFD 118 `abfd'. 119 120 #include "bfd.h" 121 122 unsigned int number_of_sections (abfd) 123 bfd *abfd; 124 { 125 return bfd_count_sections (abfd); 126 } 127 128 The abstraction used within BFD is that an object file has: 129 130 * a header, 131 132 * a number of sections containing raw data (*note Sections::), 133 134 * a set of relocations (*note Relocations::), and 135 136 * some symbol information (*note Symbols::). 137 Also, BFDs opened for archives have the additional attribute of an 138 index and contain subordinate BFDs. This approach is fine for a.out and 139 coff, but loses efficiency when applied to formats such as S-records and 140 IEEE-695. 141 142 143 File: bfd.info, Node: What BFD Version 2 Can Do, Prev: How It Works, Up: Overview 144 145 1.3 What BFD Version 2 Can Do 146 ============================= 147 148 When an object file is opened, BFD subroutines automatically determine 149 the format of the input object file. They then build a descriptor in 150 memory with pointers to routines that will be used to access elements of 151 the object file's data structures. 152 153 As different information from the object files is required, BFD 154 reads from different sections of the file and processes them. For 155 example, a very common operation for the linker is processing symbol 156 tables. Each BFD back end provides a routine for converting between 157 the object file's representation of symbols and an internal canonical 158 format. When the linker asks for the symbol table of an object file, it 159 calls through a memory pointer to the routine from the relevant BFD 160 back end which reads and converts the table into a canonical form. The 161 linker then operates upon the canonical form. When the link is finished 162 and the linker writes the output file's symbol table, another BFD back 163 end routine is called to take the newly created symbol table and 164 convert it into the chosen output format. 165 166 * Menu: 167 168 * BFD information loss:: Information Loss 169 * Canonical format:: The BFD canonical object-file format 170 171 172 File: bfd.info, Node: BFD information loss, Next: Canonical format, Up: What BFD Version 2 Can Do 173 174 1.3.1 Information Loss 175 ---------------------- 176 177 _Information can be lost during output._ The output formats supported 178 by BFD do not provide identical facilities, and information which can 179 be described in one form has nowhere to go in another format. One 180 example of this is alignment information in `b.out'. There is nowhere 181 in an `a.out' format file to store alignment information on the 182 contained data, so when a file is linked from `b.out' and an `a.out' 183 image is produced, alignment information will not propagate to the 184 output file. (The linker will still use the alignment information 185 internally, so the link is performed correctly). 186 187 Another example is COFF section names. COFF files may contain an 188 unlimited number of sections, each one with a textual section name. If 189 the target of the link is a format which does not have many sections 190 (e.g., `a.out') or has sections without names (e.g., the Oasys format), 191 the link cannot be done simply. You can circumvent this problem by 192 describing the desired input-to-output section mapping with the linker 193 command language. 194 195 _Information can be lost during canonicalization._ The BFD internal 196 canonical form of the external formats is not exhaustive; there are 197 structures in input formats for which there is no direct representation 198 internally. This means that the BFD back ends cannot maintain all 199 possible data richness through the transformation between external to 200 internal and back to external formats. 201 202 This limitation is only a problem when an application reads one 203 format and writes another. Each BFD back end is responsible for 204 maintaining as much data as possible, and the internal BFD canonical 205 form has structures which are opaque to the BFD core, and exported only 206 to the back ends. When a file is read in one format, the canonical form 207 is generated for BFD and the application. At the same time, the back 208 end saves away any information which may otherwise be lost. If the data 209 is then written back in the same format, the back end routine will be 210 able to use the canonical form provided by the BFD core as well as the 211 information it prepared earlier. Since there is a great deal of 212 commonality between back ends, there is no information lost when 213 linking or copying big endian COFF to little endian COFF, or `a.out' to 214 `b.out'. When a mixture of formats is linked, the information is only 215 lost from the files whose format differs from the destination. 216 217 218 File: bfd.info, Node: Canonical format, Prev: BFD information loss, Up: What BFD Version 2 Can Do 219 220 1.3.2 The BFD canonical object-file format 221 ------------------------------------------ 222 223 The greatest potential for loss of information occurs when there is the 224 least overlap between the information provided by the source format, 225 that stored by the canonical format, and that needed by the destination 226 format. A brief description of the canonical form may help you 227 understand which kinds of data you can count on preserving across 228 conversions. 229 230 _files_ 231 Information stored on a per-file basis includes target machine 232 architecture, particular implementation format type, a demand 233 pageable bit, and a write protected bit. Information like Unix 234 magic numbers is not stored here--only the magic numbers' meaning, 235 so a `ZMAGIC' file would have both the demand pageable bit and the 236 write protected text bit set. The byte order of the target is 237 stored on a per-file basis, so that big- and little-endian object 238 files may be used with one another. 239 240 _sections_ 241 Each section in the input file contains the name of the section, 242 the section's original address in the object file, size and 243 alignment information, various flags, and pointers into other BFD 244 data structures. 245 246 _symbols_ 247 Each symbol contains a pointer to the information for the object 248 file which originally defined it, its name, its value, and various 249 flag bits. When a BFD back end reads in a symbol table, it 250 relocates all symbols to make them relative to the base of the 251 section where they were defined. Doing this ensures that each 252 symbol points to its containing section. Each symbol also has a 253 varying amount of hidden private data for the BFD back end. Since 254 the symbol points to the original file, the private data format 255 for that symbol is accessible. `ld' can operate on a collection 256 of symbols of wildly different formats without problems. 257 258 Normal global and simple local symbols are maintained on output, 259 so an output file (no matter its format) will retain symbols 260 pointing to functions and to global, static, and common variables. 261 Some symbol information is not worth retaining; in `a.out', type 262 information is stored in the symbol table as long symbol names. 263 This information would be useless to most COFF debuggers; the 264 linker has command line switches to allow users to throw it away. 265 266 There is one word of type information within the symbol, so if the 267 format supports symbol type information within symbols (for 268 example, COFF, IEEE, Oasys) and the type is simple enough to fit 269 within one word (nearly everything but aggregates), the 270 information will be preserved. 271 272 _relocation level_ 273 Each canonical BFD relocation record contains a pointer to the 274 symbol to relocate to, the offset of the data to relocate, the 275 section the data is in, and a pointer to a relocation type 276 descriptor. Relocation is performed by passing messages through 277 the relocation type descriptor and the symbol pointer. Therefore, 278 relocations can be performed on output data using a relocation 279 method that is only available in one of the input formats. For 280 instance, Oasys provides a byte relocation format. A relocation 281 record requesting this relocation type would point indirectly to a 282 routine to perform this, so the relocation may be performed on a 283 byte being written to a 68k COFF file, even though 68k COFF has no 284 such relocation type. 285 286 _line numbers_ 287 Object formats can contain, for debugging purposes, some form of 288 mapping between symbols, source line numbers, and addresses in the 289 output file. These addresses have to be relocated along with the 290 symbol information. Each symbol with an associated list of line 291 number records points to the first record of the list. The head 292 of a line number list consists of a pointer to the symbol, which 293 allows finding out the address of the function whose line number 294 is being described. The rest of the list is made up of pairs: 295 offsets into the section and line numbers. Any format which can 296 simply derive this information can pass it successfully between 297 formats (COFF, IEEE and Oasys). 298 299 300 File: bfd.info, Node: BFD front end, Next: BFD back ends, Prev: Overview, Up: Top 301 302 2 BFD Front End 303 *************** 304 305 2.1 `typedef bfd' 306 ================= 307 308 A BFD has type `bfd'; objects of this type are the cornerstone of any 309 application using BFD.

If MESSAGE is non-NULL and non-empty, the error 650 string printed is preceded by MESSAGE, a colon, and a space. It is 651 followed by a newline. 652 653 2.2.2 BFD error handler 654 ----------------------- 655 656 Some BFD functions want to print messages describing the problem. They 657 call a BFD error handler function. This function may be overridden by 658 the program. 659 660 The BFD error handler acts like printf. 661 662 663 typedef void (*bfd_error_handler_type) (const char *, ...); 664 665 2.2.2.1 `bfd_set_error_handler' 666 ............................... 667 668 *Synopsis* 669 bfd_error_handler_type bfd_set_error_handler (bfd_error_handler_type); 670 *Description* 671 Set the BFD error handler function.

E.g., an attempt 748 was made to set the `D_PAGED' bit on a BFD format which does not 749 support demand paging. 750 751 2.3.1.5 `bfd_get_arch_size' 752 ........................... 753 754 *Synopsis* 755 int bfd_get_arch_size (bfd *abfd); 756 *Description* 757 Returns the architecture address size, in bits, as determined by the 758 object file's format.

Some architectures implicitly sign extend address values when 772 they are converted to types larger than the size of an address. For 773 instance, bfd_get_start_address() will return an address sign extended 774 to fill a bfd_vma when this is the case. 775 776 *Returns* 777 Returns `1' if the target architecture is known to sign extend 778 addresses, `0' if the target architecture is known to not sign extend 779 addresses, and `-1' otherwise. 780 781 2.3.1.7 `bfd_set_start_address' 782 ............................... 783 784 *Synopsis* 785 bfd_boolean bfd_set_start_address (bfd *abfd, bfd_vma vma); 786 *Description* 787 Make VMA the entry point of output BFD ABFD. 788 789 *Returns* 790 Returns `TRUE' on success, `FALSE' otherwise. 791 792 2.3.1.8 `bfd_get_gp_size' 793 ......................... 794 795 *Synopsis* 796 unsigned int bfd_get_gp_size (bfd *abfd); 797 *Description* 798 Return the maximum size of objects to be optimized using the GP 799 register under MIPS ECOFF.

(Though without as many bells and 820 whistles as `strtoul'.) The expression is assumed to be unsigned 821 (i.e., positive). If given a BASE, it is used as the base for 822 conversion. A base of 0 causes the function to interpret the string in 823 hex if a leading "0x" or "0X" is found, otherwise in octal if a leading 824 zero is found, otherwise in decimal. 825 826 If the value would overflow, the maximum `bfd_vma' value is returned. 827 828 2.3.1.11 `bfd_copy_private_header_data' 829 ....................................... 830 831 *Synopsis* 832 bfd_boolean bfd_copy_private_header_data (bfd *ibfd, bfd *obfd); 833 *Description* 834 Copy private BFD header information from the BFD IBFD to the the BFD 835 OBFD.

It 1151 would be ideal if someone could eventually modify it so that such 1152 results were guaranteed. 1153 1154 Instead, we want to ask questions like "is this NNN byte sized 1155 object I'm about to try read from file offset YYY reasonable?" As as 1156 example of where we might do this, some object formats use string 1157 tables for which the first `sizeof (long)' bytes of the table contain 1158 the size of the table itself, including the size bytes. If an 1159 application tries to read what it thinks is one of these string tables, 1160 without some way to validate the size, and for some reason the size is 1161 wrong (byte swapping error, wrong location for the string table, etc.), 1162 the only clue is likely to be a read error when it tries to read the 1163 table, or a "virtual memory exhausted" error when it tries to allocate 1164 15 bazillon bytes of space for the 15 bazillon byte table it is about 1165 to read. This function at least allows us to answer the question, "is 1166 the size reasonable?". 1167 1168 2.3.1.28 `bfd_mmap' 1169 ................... 1170 1171 *Synopsis* 1172 void *bfd_mmap (bfd *abfd, void *addr, bfd_size_type len, 1173 int prot, int flags, file_ptr offset); 1174 *Description* 1175 Return mmap()ed region of the file, if possible and implemented. 1176 1177 * Menu: 1178 1179 * Memory Usage:: 1180 * Initialization:: 1181 * Sections:: 1182 * Symbols:: 1183 * Archives:: 1184 * Formats:: 1185 * Relocations:: 1186 * Core Files:: 1187 * Targets:: 1188 * Architectures:: 1189 * Opening and Closing:: 1190 * Internal:: 1191 * File Caching:: 1192 * Linker Functions:: 1193 * Hash Tables:: 1194 1195 1196 File: bfd.info, Node: Memory Usage, Next: Initialization, Prev: BFD front end, Up: BFD front end 1197 1198 2.4 Memory Usage 1199 ================ 1200 1201 BFD keeps all of its internal structures in obstacks. There is one 1202 obstack per open BFD file, into which the current state is stored. When 1203 a BFD is closed, the obstack is deleted, and so everything which has 1204 been allocated by BFD for the closing file is thrown away. 1205 1206 BFD does not free anything created by an application, but pointers 1207 into `bfd' structures become invalid on a `bfd_close'; for example, 1208 after a `bfd_close' the vector passed to `bfd_canonicalize_symtab' is 1209 still around, since it has been allocated by the application, but the 1210 data that it pointed to are lost. 1211 1212 The general rule is to not close a BFD until all operations dependent 1213 upon data from the BFD have been completed, or all the data from within 1214 the file has been copied. To help with the management of memory, there 1215 is a function (`bfd_alloc_size') which returns the number of bytes in 1216 obstacks associated with the supplied BFD. This could be used to select 1217 the greediest open BFD, close it to reclaim the memory, perform some 1218 operation and reopen the BFD again, to get a fresh copy of the data 1219 structures. 1220 1221 1222 File: bfd.info, Node: Initialization, Next: Sections, Prev: Memory Usage, Up: BFD front end 1223 1224 2.5 Initialization 1225 ================== 1226 1227 2.5.1 Initialization functions 1228 ------------------------------ 1229 1230 These are the functions that handle initializing a BFD. 1231 1232 2.5.1.1 `bfd_init' 1233 .................. 1234 1235 *Synopsis* 1236 void bfd_init (void); 1237 *Description* 1238 This routine must be called before any other BFD function to initialize 1239 magical internal data structures. 1240 1241 1242 File: bfd.info, Node: Sections, Next: Symbols, Prev: Initialization, Up: BFD front end 1243 1244 2.6 Sections 1245 ============ 1246 1247 The raw data contained within a BFD is maintained through the section 1248 abstraction. A single BFD may have any number of sections. It keeps 1249 hold of them by pointing to the first; each one points to the next in 1250 the list. 1251 1252 Sections are supported in BFD in `section.c'. 1253 1254 * Menu: 1255 1256 * Section Input:: 1257 * Section Output:: 1258 * typedef asection:: 1259 * section prototypes:: 1260 1261 1262 File: bfd.info, Node: Section Input, Next: Section Output, Prev: Sections, Up: Sections 1263 1264 2.6.1 Section input 1265 ------------------- 1266 1267 When a BFD is opened for reading, the section structures are created 1268 and attached to the BFD. 1269 1270 Each section has a name which describes the section in the outside 1271 world--for example, `a.out' would contain at least three sections, 1272 called `.text', `.data' and `.bss'. 1273 1274 Names need not be unique; for example a COFF file may have several 1275 sections named `.data'. 1276 1277 Sometimes a BFD will contain more than the "natural" number of 1278 sections. A back end may attach other sections containing constructor 1279 data, or an application may add a section (using `bfd_make_section') to 1280 the sections attached to an already open BFD. For example, the linker 1281 creates an extra section `COMMON' for each input file's BFD to hold 1282 information about common storage. 1283 1284 The raw data is not necessarily read in when the section descriptor 1285 is created. Some targets may leave the data in place until a 1286 `bfd_get_section_contents' call is made. Other back ends may read in 1287 all the data at once. For example, an S-record file has to be read 1288 once to determine the size of the data. An IEEE-695 file doesn't 1289 contain raw data in sections, but data and relocation expressions 1290 intermixed, so the data area has to be parsed to get out the data and 1291 relocations. 1292 1293 1294 File: bfd.info, Node: Section Output, Next: typedef asection, Prev: Section Input, Up: Sections 1295 1296 2.6.2 Section output 1297 -------------------- 1298 1299 To write a new object style BFD, the various sections to be written 1300 have to be created. They are attached to the BFD in the same way as 1301 input sections; data is written to the sections using 1302 `bfd_set_section_contents'. 1303 1304 Any program that creates or combines sections (e.g., the assembler 1305 and linker) must use the `asection' fields `output_section' and 1306 `output_offset' to indicate the file sections to which each section 1307 must be written. (If the section is being created from scratch, 1308 `output_section' should probably point to the section itself and 1309 `output_offset' should probably be zero.) 1310 1311 The data to be written comes from input sections attached (via 1312 `output_section' pointers) to the output sections. The output section 1313 structure can be considered a filter for the input section: the output 1314 section determines the vma of the output data and the name, but the 1315 input section determines the offset into the output section of the data 1316 to be written. 1317 1318 E.g., to create a section "O", starting at 0x100, 0x123 long, 1319 containing two subsections, "A" at offset 0x0 (i.e., at vma 0x100) and 1320 "B" at offset 0x20 (i.e., at vma 0x120) the `asection' structures would 1321 look like: 1322 1323 section name "A" 1324 output_offset 0x00 1325 size 0x20 1326 output_section -----------> section name "O" 1327 | vma 0x100 1328 section name "B" | size 0x123 1329 output_offset 0x20 | 1330 size 0x103 | 1331 output_section --------| 1332 1333 2.6.3 Link orders 1334 ----------------- 1335 1336 The data within a section is stored in a "link_order". These are much 1337 like the fixups in `gas'. The link_order abstraction allows a section 1338 to grow and shrink within itself. 1339 1340 A link_order knows how big it is, and which is the next link_order 1341 and where the raw data for it is; it also points to a list of 1342 relocations which apply to it. 1343 1344 The link_order is used by the linker to perform relaxing on final 1345 code. The compiler creates code which is as big as necessary to make 1346 it work without relaxing, and the user can select whether to relax. 1347 Sometimes relaxing takes a lot of time. The linker runs around the 1348 relocations to see if any are attached to data which can be shrunk, if 1349 so it does it on a link_order by link_order basis. 1350 1351 1352 File: bfd.info, Node: typedef asection, Next: section prototypes, Prev: Section Output, Up: Sections 1353 1354 2.6.4 typedef asection 1355 ---------------------- 1356 1357 Here is the section structure: 1358 1359 1360 typedef struct bfd_section 1361 { 1362 /* The name of the section; the name isn't a copy, the pointer is 1363 the same as that passed to bfd_make_section. */ 1364 const char *name; 1365 1366 /* A unique sequence number. */ 1367 int id; 1368 1369 /* Which section in the bfd; 0..n-1 as sections are created in a bfd. */ 1370 int index; 1371 1372 /* The next section in the list belonging to the BFD, or NULL. */ 1373 struct bfd_section *next; 1374 1375 /* The previous section in the list belonging to the BFD, or NULL. */ 1376 struct bfd_section *prev; 1377 1378 /* The field flags contains attributes of the section.

BFD passes information to 2194 applications though the `asymbol' structure. When the application 2195 requests the symbol table, BFD reads the table in the native form and 2196 translates parts of it into the internal format. To maintain more than 2197 the information passed to applications, some targets keep some 2198 information "behind the scenes" in a structure only the particular back 2199 end knows about. For example, the coff back end keeps the original 2200 symbol table structure as well as the canonical structure when a BFD is 2201 read in. On output, the coff back end can reconstruct the output symbol 2202 table so that no information is lost, even information unique to coff 2203 which BFD doesn't know or understand. If a coff symbol table were read, 2204 but were written through an a.out back end, all the coff specific 2205 information would be lost. The symbol table of a BFD is not necessarily 2206 read in until a canonicalize request is made. Then the BFD back end 2207 fills in a table provided by the application with pointers to the 2208 canonical information. To output symbols, the application provides BFD 2209 with a table of pointers to pointers to `asymbol's. This allows 2210 applications like the linker to output a symbol as it was read, since 2211 the "behind the scenes" information will be still available. 2212 2213 * Menu: 2214 2215 * Reading Symbols:: 2216 * Writing Symbols:: 2217 * Mini Symbols:: 2218 * typedef asymbol:: 2219 * symbol handling functions:: 2220 2221 2222 File: bfd.info, Node: Reading Symbols, Next: Writing Symbols, Prev: Symbols, Up: Symbols 2223 2224 2.7.1 Reading symbols 2225 --------------------- 2226 2227 There are two stages to reading a symbol table from a BFD: allocating 2228 storage, and the actual reading process. This is an excerpt from an 2229 application which reads the symbol table: 2230 2231 long storage_needed; 2232 asymbol **symbol_table; 2233 long number_of_symbols; 2234 long i; 2235 2236 storage_needed = bfd_get_symtab_upper_bound (abfd); 2237 2238 if (storage_needed < 0) 2239 FAIL 2240 2241 if (storage_needed == 0) 2242 return; 2243 2244 symbol_table = xmalloc (storage_needed); 2245 ... 2246 number_of_symbols = 2247 bfd_canonicalize_symtab (abfd, symbol_table); 2248 2249 if (number_of_symbols < 0) 2250 FAIL 2251 2252 for (i = 0; i < number_of_symbols; i++) 2253 process_symbol (symbol_table[i]); 2254 2255 All storage for the symbols themselves is in an objalloc connected 2256 to the BFD; it is freed when the BFD is closed. 2257 2258 2259 File: bfd.info, Node: Writing Symbols, Next: Mini Symbols, Prev: Reading Symbols, Up: Symbols 2260 2261 2.7.2 Writing symbols 2262 --------------------- 2263 2264 Writing of a symbol table is automatic when a BFD open for writing is 2265 closed. The application attaches a vector of pointers to pointers to 2266 symbols to the BFD being written, and fills in the symbol count. The 2267 close and cleanup code reads through the table provided and performs 2268 all the necessary operations. The BFD output code must always be 2269 provided with an "owned" symbol: one which has come from another BFD, 2270 or one which has been created using `bfd_make_empty_symbol'. Here is an 2271 example showing the creation of a symbol table with only one element: 2272 2273 #include "bfd.h" 2274 int main (void) 2275 { 2276 bfd *abfd; 2277 asymbol *ptrs[2]; 2278 asymbol *new; 2279 2280 abfd = bfd_openw ("foo","a.out-sunos-big"); 2281 bfd_set_format (abfd, bfd_object); 2282 new = bfd_make_empty_symbol (abfd); 2283 new->name = "dummy_symbol"; 2284 new->section = bfd_make_section_old_way (abfd, ".text"); 2285 new->flags = BSF_GLOBAL; 2286 new->value = 0x12345; 2287 2288 ptrs[0] = new; 2289 ptrs[1] = 0; 2290 2291 bfd_set_symtab (abfd, ptrs, 1); 2292 bfd_close (abfd); 2293 return 0; 2294 } 2295 2296 ./makesym 2297 nm foo 2298 00012345 A dummy_symbol 2299 2300 Many formats cannot represent arbitrary symbol information; for 2301 instance, the `a.out' object format does not allow an arbitrary number 2302 of sections. A symbol pointing to a section which is not one of 2303 `.text', `.data' or `.bss' cannot be described. 2304 2305 2306 File: bfd.info, Node: Mini Symbols, Next: typedef asymbol, Prev: Writing Symbols, Up: Symbols 2307 2308 2.7.3 Mini Symbols 2309 ------------------ 2310 2311 Mini symbols provide read-only access to the symbol table. They use 2312 less memory space, but require more time to access. They can be useful 2313 for tools like nm or objdump, which may have to handle symbol tables of 2314 extremely large executables. 2315 2316 The `bfd_read_minisymbols' function will read the symbols into 2317 memory in an internal form.

It has a symbol table, 2646 although there's not much a user program will do with it. 2647 2648 The big difference between an archive BFD and an ordinary BFD is 2649 that the archive doesn't have sections. Instead it has a chain of BFDs 2650 that are considered its contents. These BFDs can be manipulated like 2651 any other. The BFDs contained in an archive opened for reading will 2652 all be opened for reading. You may put either input or output BFDs 2653 into an archive opened for output; they will be handled correctly when 2654 the archive is closed. 2655 2656 Use `bfd_openr_next_archived_file' to step through the contents of 2657 an archive opened for input. You don't have to read the entire archive 2658 if you don't want to! Read it until you find what you want. 2659 2660 Archive contents of output BFDs are chained through the `next' 2661 pointer in a BFD. The first one is findable through the `archive_head' 2662 slot of the archive. Set it with `bfd_set_archive_head' (q.v.). A 2663 given BFD may be in only one open output archive at a time. 2664 2665 As expected, the BFD archive code is more general than the archive 2666 code of any given environment. BFD archives may contain files of 2667 different formats (e.g., a.out and coff) and even different 2668 architectures. You may even place archives recursively into archives! 2669 2670 This can cause unexpected confusion, since some archive formats are 2671 more expressive than others. For instance, Intel COFF archives can 2672 preserve long filenames; SunOS a.out archives cannot. If you move a 2673 file from the first to the second format and back again, the filename 2674 may be truncated. Likewise, different a.out environments have different 2675 conventions as to how they truncate filenames, whether they preserve 2676 directory names in filenames, etc. When interoperating with native 2677 tools, be sure your files are homogeneous. 2678 2679 Beware: most of these formats do not react well to the presence of 2680 spaces in filenames. We do the best we can, but can't always handle 2681 this case due to restrictions in the format of archives. Many Unix 2682 utilities are braindead in regards to spaces and such in filenames 2683 anyway, so this shouldn't be much of a restriction. 2684 2685 Archives are supported in BFD in `archive.c'. 2686 2687 2.8.1 Archive functions 2688 ----------------------- 2689 2690 2.8.1.1 `bfd_get_next_mapent' 2691 ............................. 2692 2693 *Synopsis* 2694 symindex bfd_get_next_mapent 2695 (bfd *abfd, symindex previous, carsym **sym); 2696 *Description* 2697 Step through archive ABFD's symbol table (if it has one).

The symbol is referenced through a pointer to a pointer so 2904 that tools like the linker can fix up all the symbols of the same name 2905 by modifying only one pointer. The relocation routine looks in the 2906 symbol and uses the base of the section the symbol is attached to and 2907 the value of the symbol as the initial relocation offset. If the symbol 2908 pointer is zero, then the section provided is looked up. 2909 2910 * `address' 2911 The `address' field gives the offset in bytes from the base of the 2912 section data which owns the relocation record to the first byte of 2913 relocatable information. The actual data relocated will be relative to 2914 this point; for example, a relocation type which modifies the bottom 2915 two bytes of a four byte word would not touch the first byte pointed to 2916 in a big endian world. 2917 2918 * `addend' 2919 The `addend' is a value provided by the back end to be added (!) to 2920 the relocation offset. Its interpretation is dependent upon the howto. 2921 For example, on the 68k the code: 2922 2923 char foo[]; 2924 main() 2925 { 2926 return foo[0x12345678]; 2927 } 2928 2929 Could be compiled into: 2930 2931 linkw fp,#-4 2932 moveb @#12345678,d0 2933 extbl d0 2934 unlk fp 2935 rts 2936 2937 This could create a reloc pointing to `foo', but leave the offset in 2938 the data, something like: 2939 2940 RELOCATION RECORDS FOR [.text]: 2941 offset type value 2942 00000006 32 _foo 2943 2944 00000000 4e56 fffc ; linkw fp,#-4 2945 00000004 1039 1234 5678 ; moveb @#12345678,d0 2946 0000000a 49c0 ; extbl d0 2947 0000000c 4e5e ; unlk fp 2948 0000000e 4e75 ; rts 2949 2950 Using coff and an 88k, some instructions don't have enough space in 2951 them to represent the full address range, and pointers have to be 2952 loaded in two parts. So you'd get something like: 2953 2954 or.u r13,r0,hi16(_foo+0x12345678) 2955 ld.b r2,r13,lo16(_foo+0x12345678) 2956 jmp r1 2957 2958 This should create two relocs, both pointing to `_foo', and with 2959 0x12340000 in their addend field. The data would consist of: 2960 2961 RELOCATION RECORDS FOR [.text]: 2962 offset type value 2963 00000002 HVRT16 _foo+0x12340000 2964 00000006 LVRT16 _foo+0x12340000 2965 2966 00000000 5da05678 ; or.u r13,r0,0x5678 2967 00000004 1c4d5678 ; ld.b r2,r13,0x5678 2968 00000008 f400c001 ; jmp r1 2969 2970 The relocation routine digs out the value from the data, adds it to 2971 the addend to get the original offset, and then adds the value of 2972 `_foo'. Note that all 32 bits have to be kept around somewhere, to cope 2973 with carry from bit 15 to bit 16. 2974 2975 One further example is the sparc and the a.out format. The sparc has 2976 a similar problem to the 88k, in that some instructions don't have room 2977 for an entire offset, but on the sparc the parts are created in odd 2978 sized lumps. The designers of the a.out format chose to not use the 2979 data within the section for storing part of the offset; all the offset 2980 is kept within the reloc. Anything in the data should be ignored. 2981 2982 save %sp,-112,%sp 2983 sethi %hi(_foo+0x12345678),%g2 2984 ldsb [%g2+%lo(_foo+0x12345678)],%i0 2985 ret 2986 restore 2987 2988 Both relocs contain a pointer to `foo', and the offsets contain junk. 2989 2990 RELOCATION RECORDS FOR [.text]: 2991 offset type value 2992 00000004 HI22 _foo+0x12345678 2993 00000008 LO10 _foo+0x12345678 2994 2995 00000000 9de3bf90 ; save %sp,-112,%sp 2996 00000004 05000000 ; sethi %hi(_foo+0),%g2 2997 00000008 f048a000 ; ldsb [%g2+%lo(_foo+0)],%i0 2998 0000000c 81c7e008 ; ret 2999 00000010 81e80000 ; restore 3000 3001 * `howto' 3002 The `howto' field can be imagined as a relocation instruction. It is 3003 a pointer to a structure which contains information on what to do with 3004 all of the other information in the reloc record and data section. A 3005 back end would normally have a relocation instruction set and turn 3006 relocations into pointers to the correct structure on input - but it 3007 would be possible to create each howto field on demand. 3008 3009 2.10.1.1 `enum complain_overflow' 3010 ................................. 3011 3012 Indicates what sort of overflow checking should be done when performing 3013 a relocation. 3014 3015 3016 enum complain_overflow 3017 { 3018 /* Do not complain on overflow. */ 3019 complain_overflow_dont, 3020 3021 /* Complain if the value overflows when considered as a signed 3022 number one bit larger than the field. ie.

There are two 3221 ways of reflecting the results of partial linkage in an output file: by 3222 modifying the output data in place, and by modifying the relocation 3223 record. Some native formats (e.g., basic a.out and basic coff) have no 3224 way of specifying an addend in the relocation type, so the addend has 3225 to go in the output data. This is no big deal since in these formats 3226 the output data slot will always be big enough for the addend. Complex 3227 reloc types with addends were invented to solve just this problem.

Some of these treat the symbol or 3484 "addend" in some special way. For GPDISP_HI16 ("gpdisp") 3485 relocations, the symbol is ignored when writing; when reading, it 3486 will be the absolute section symbol. The addend is the 3487 displacement in bytes of the "lda" instruction from the "ldah" 3488 instruction (which is at the address of this reloc). 3489 3490 -- : BFD_RELOC_ALPHA_GPDISP_LO16 3491 For GPDISP_LO16 ("ignore") relocations, the symbol is handled as 3492 with GPDISP_HI16 relocs.

The addend is ignored when writing, but is filled 3511 in with the file's GP value on reading, for convenience, as with 3512 the GPDISP_LO16 reloc. 3513 3514 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and 3515 GPDISP_LO16.

All the back end provides to the root part of BFD is a 5683 structure containing pointers to functions which perform certain low 5684 level operations on files. BFD translates the applications's requests 5685 through a pointer into calls to the back end routines. 5686 5687 When a file is opened with `bfd_openr', its format and target are 5688 unknown. BFD uses various mechanisms to determine how to interpret the 5689 file. The operations performed are: 5690 5691 * Create a BFD by calling the internal routine `_bfd_new_bfd', then 5692 call `bfd_find_target' with the target string supplied to 5693 `bfd_openr' and the new BFD pointer. 5694 5695 * If a null target string was provided to `bfd_find_target', look up 5696 the environment variable `GNUTARGET' and use that as the target 5697 string. 5698 5699 * If the target string is still `NULL', or the target string is 5700 `default', then use the first item in the target vector as the 5701 target type, and set `target_defaulted' in the BFD to cause 5702 `bfd_check_format' to loop through all the targets. *Note 5703 bfd_target::. *Note Formats::. 5704 5705 * Otherwise, inspect the elements in the target vector one by one, 5706 until a match on target name is found. When found, use it. 5707 5708 * Otherwise return the error `bfd_error_invalid_target' to 5709 `bfd_openr'. 5710 5711 * `bfd_openr' attempts to open the file using `bfd_open_file', and 5712 returns the BFD. 5713 Once the BFD has been opened and the target selected, the file 5714 format may be determined. This is done by calling `bfd_check_format' on 5715 the BFD with a suggested format. If `target_defaulted' has been set, 5716 each possible target type is tried to see if it recognizes the 5717 specified format. `bfd_check_format' returns `TRUE' when the caller 5718 guesses right. 5719 5720 * Menu: 5721 5722 * bfd_target:: 5723 5724 5725 File: bfd.info, Node: bfd_target, Prev: Targets, Up: Targets 5726 5727 2.12.1 bfd_target 5728 ----------------- 5729 5730 *Description* 5731 This structure contains everything that BFD knows about a target. It 5732 includes things like its byte order, name, and which routines to call 5733 to do various operations. 5734 5735 Every BFD points to a target structure with its `xvec' member. 5736 5737 The macros below are used to dispatch to functions through the 5738 `bfd_target' vector. They are used in a number of macros further down 5739 in `bfd.h', and are also used when calling various routines by hand 5740 inside the BFD implementation. The ARGLIST argument must be 5741 parenthesized; it contains all the arguments to the called function. 5742 5743 They make the documentation (more) unpleasant to read, so if someone 5744 wants to fix this and not break the above, please do. 5745 #define BFD_SEND(bfd, message, arglist) \ 5746 ((*((bfd)->xvec->message)) arglist) 5747 5748 #ifdef DEBUG_BFD_SEND 5749 #undef BFD_SEND 5750 #define BFD_SEND(bfd, message, arglist) \ 5751 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \ 5752 ((*((bfd)->xvec->message)) arglist) : \ 5753 (bfd_assert (__FILE__,__LINE__), NULL)) 5754 #endif 5755 For operations which index on the BFD format: 5756 #define BFD_SEND_FMT(bfd, message, arglist) \ 5757 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) 5758 5759 #ifdef DEBUG_BFD_SEND 5760 #undef BFD_SEND_FMT 5761 #define BFD_SEND_FMT(bfd, message, arglist) \ 5762 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \ 5763 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \ 5764 (bfd_assert (__FILE__,__LINE__), NULL)) 5765 #endif 5766 This is the structure which defines the type of BFD this is. The 5767 `xvec' member of the struct `bfd' itself points here. Each module that 5768 implements access to a different target under BFD, defines one of these. 5769 5770 FIXME, these names should be rationalised with the names of the 5771 entry points which call them. Too bad we can't have one macro to define 5772 them both! 5773 enum bfd_flavour 5774 { 5775 bfd_target_unknown_flavour, 5776 bfd_target_aout_flavour, 5777 bfd_target_coff_flavour, 5778 bfd_target_ecoff_flavour, 5779 bfd_target_xcoff_flavour, 5780 bfd_target_elf_flavour, 5781 bfd_target_ieee_flavour, 5782 bfd_target_nlm_flavour, 5783 bfd_target_oasys_flavour, 5784 bfd_target_tekhex_flavour, 5785 bfd_target_srec_flavour, 5786 bfd_target_verilog_flavour, 5787 bfd_target_ihex_flavour, 5788 bfd_target_som_flavour, 5789 bfd_target_os9k_flavour, 5790 bfd_target_versados_flavour, 5791 bfd_target_msdos_flavour, 5792 bfd_target_ovax_flavour, 5793 bfd_target_evax_flavour, 5794 bfd_target_mmo_flavour, 5795 bfd_target_mach_o_flavour, 5796 bfd_target_pef_flavour, 5797 bfd_target_pef_xlib_flavour, 5798 bfd_target_sym_flavour 5799 }; 5800 5801 enum bfd_endian { BFD_ENDIAN_BIG, BFD_ENDIAN_LITTLE, BFD_ENDIAN_UNKNOWN }; 5802 5803 /* Forward declaration. */ 5804 typedef struct bfd_link_info _bfd_link_info; 5805 5806 typedef struct bfd_target 5807 { 5808 /* Identifies the kind of target, e.g., SunOS4, Ultrix, etc. */ 5809 char *name; 5810 5811 /* The "flavour" of a back end is a general indication about 5812 the contents of a file. */ 5813 enum bfd_flavour flavour; 5814 5815 /* The order of bytes within the data area of a file. */ 5816 enum bfd_endian byteorder; 5817 5818 /* The order of bytes within the header parts of a file. */ 5819 enum bfd_endian header_byteorder; 5820 5821 /* A mask of all the flags which an executable may have set - 5822 from the set `BFD_NO_FLAGS', `HAS_RELOC', ...`D_PAGED'. */ 5823 flagword object_flags; 5824 5825 /* A mask of all the flags which a section may have set - from 5826 the set `SEC_NO_FLAGS', `SEC_ALLOC', ...`SET_NEVER_LOAD'. */ 5827 flagword section_flags; 5828 5829 /* The character normally found at the front of a symbol. 5830 (if any), perhaps `_'. */ 5831 char symbol_leading_char; 5832 5833 /* The pad character for file names within an archive header. */ 5834 char ar_pad_char; 5835 5836 /* The maximum number of characters in an archive header. */ 5837 unsigned short ar_max_namelen; 5838 5839 /* Entries for byte swapping for data.

The set of default architectures is selected by the macro 6257 `SELECT_ARCHITECTURES'. This is normally set up in the 6258 `config/TARGET.mt' file of your choice. If the name is not defined, 6259 then all the architectures supported are included. 6260 6261 When BFD starts up, all the architectures are called with an 6262 initialize method. It is up to the architecture back end to insert as 6263 many items into the list of architectures as it wants to; generally 6264 this would be one for each machine and one for the default case (an 6265 item with a machine field of 0). 6266 6267 BFD's idea of an architecture is implemented in `archures.c'. 6268 6269 2.13.1 bfd_architecture 6270 ----------------------- 6271 6272 *Description* 6273 This enum gives the object file's CPU architecture, in a global 6274 sense--i.e., what processor family does it belong to? Another field 6275 indicates which processor within the family is in use. The machine 6276 gives a number which distinguishes different versions of the 6277 architecture, containing, for example, 2 and 3 for Intel i960 KA and 6278 i960 KB, and 68020 and 68030 for Motorola

It 6897 opens a BFD on a file already described by the FD supplied. 6898 6899 When the file is later `bfd_close'd, the file descriptor will be 6900 closed. If the caller desires that this file descriptor be cached by 6901 BFD (opened as needed, closed as needed to free descriptors for other 6902 opens), with the supplied FD used as an initial file descriptor (but 6903 subject to closure at any time), call bfd_set_cacheable(bfd, 1) on the 6904 returned BFD. The default is to assume no caching; the file descriptor 6905 will remain open until `bfd_close', and will not be affected by BFD 6906 operations on other files. 6907 6908 Possible errors are `bfd_error_no_memory', 6909 `bfd_error_invalid_target' and `bfd_error_system_call'. 6910 6911 2.14.1.4 `bfd_openstreamr' 6912 .......................... 6913 6914 *Synopsis* 6915 bfd *bfd_openstreamr (const char *, const char *, void *); 6916 *Description* 6917 Open a BFD for read access on an existing stdio stream.

The STREAM is 6940 created using OPEN_FUNC, accessed using PREAD_FUNC and destroyed using 6941 CLOSE_FUNC. 6942 6943 Calls `bfd_find_target', so TARGET is interpreted as by that 6944 function. 6945 6946 Calls OPEN_FUNC (which can call `bfd_zalloc' and `bfd_get_filename') 6947 to obtain the read-only stream backing the BFD. OPEN_FUNC either 6948 succeeds returning the non-`NULL' STREAM, or fails returning `NULL' 6949 (setting `bfd_error'). 6950 6951 Calls PREAD_FUNC to request NBYTES of data from STREAM starting at 6952 OFFSET (e.g., via a call to `bfd_read'). PREAD_FUNC either succeeds 6953 returning the number of bytes read (which can be less than NBYTES when 6954 end-of-file), or fails returning -1 (setting `bfd_error'). 6955 6956 Calls CLOSE_FUNC when the BFD is later closed using `bfd_close'. 6957 CLOSE_FUNC either succeeds returning 0, or fails returning -1 (setting 6958 `bfd_error'). 6959 6960 Calls STAT_FUNC to fill in a stat structure for bfd_stat, 6961 bfd_get_size, and bfd_get_mtime calls. STAT_FUNC returns 0 on success, 6962 or returns -1 on failure (setting `bfd_error'). 6963 6964 If `bfd_openr_iovec' returns `NULL' then an error has occurred. 6965 Possible errors are `bfd_error_no_memory', `bfd_error_invalid_target' 6966 and `bfd_error_system_call'. 6967 6968 2.14.1.6 `bfd_openw' 6969 .................... 6970 6971 *Synopsis* 6972 bfd *bfd_openw (const char *filename, const char *target); 6973 *Description* 6974 Create a BFD, associated with file FILENAME, using the file format 6975 TARGET, and return a pointer to it. 6976 6977 Possible errors are `bfd_error_system_call', `bfd_error_no_memory', 6978 `bfd_error_invalid_target'. 6979 6980 2.14.1.7 `bfd_close' 6981 .................... 6982 6983 *Synopsis* 6984 bfd_boolean bfd_close (bfd *abfd); 6985 *Description* 6986 Close a BFD.

The mangling performs any necessary endian 7218 translations and removes alignment restrictions. Note that types 7219 accepted and returned by these macros are identical so they can be 7220 swapped around in macros--for example, `libaout.h' defines `GET_WORD' 7221 to either `bfd_get_32' or `bfd_get_64'. 7222 7223 In the put routines, VAL must be a `bfd_vma'. If we are on a system 7224 without prototypes, the caller is responsible for making sure that is 7225 true, with a cast if necessary. We don't cast them in the macro 7226 definitions because that would prevent `lint' or `gcc -Wall' from 7227 detecting sins such as passing a pointer. To detect calling these with 7228 less than a `bfd_vma', use `gcc -Wconversion' on a host with 64 bit 7229 `bfd_vma''s. 7230 7231 /* Byte swapping macros for user section data. */ 7232 7233 #define bfd_put_8(abfd, val, ptr) \ 7234 ((void) (*((unsigned char *) (ptr)) = (val) & 0xff)) 7235 #define bfd_put_signed_8 \ 7236 bfd_put_8 7237 #define bfd_get_8(abfd, ptr) \ 7238 (*(unsigned char *) (ptr) & 0xff) 7239 #define bfd_get_signed_8(abfd, ptr) \ 7240 (((*(unsigned char *) (ptr) & 0xff) ^ 0x80) - 0x80) 7241 7242 #define bfd_put_16(abfd, val, ptr) \ 7243 BFD_SEND (abfd, bfd_putx16, ((val),(ptr))) 7244 #define bfd_put_signed_16 \ 7245 bfd_put_16 7246 #define bfd_get_16(abfd, ptr) \ 7247 BFD_SEND (abfd, bfd_getx16, (ptr)) 7248 #define bfd_get_signed_16(abfd, ptr) \ 7249 BFD_SEND (abfd, bfd_getx_signed_16, (ptr)) 7250 7251 #define bfd_put_32(abfd, val, ptr) \ 7252 BFD_SEND (abfd, bfd_putx32, ((val),(ptr))) 7253 #define bfd_put_signed_32 \ 7254 bfd_put_32 7255 #define bfd_get_32(abfd, ptr) \ 7256 BFD_SEND (abfd, bfd_getx32, (ptr)) 7257 #define bfd_get_signed_32(abfd, ptr) \ 7258 BFD_SEND (abfd, bfd_getx_signed_32, (ptr)) 7259 7260 #define bfd_put_64(abfd, val, ptr) \ 7261 BFD_SEND (abfd, bfd_putx64, ((val), (ptr))) 7262 #define bfd_put_signed_64 \ 7263 bfd_put_64 7264 #define bfd_get_64(abfd, ptr) \ 7265 BFD_SEND (abfd, bfd_getx64, (ptr)) 7266 #define bfd_get_signed_64(abfd, ptr) \ 7267 BFD_SEND (abfd, bfd_getx_signed_64, (ptr)) 7268 7269 #define bfd_get(bits, abfd, ptr) \ 7270 ((bits) == 8 ?

The module in `cache.c' maintains a least recently used 7369 list of `BFD_CACHE_MAX_OPEN' files, and exports the name 7370 `bfd_cache_lookup', which runs around and makes sure that the required 7371 BFD is open. If not, then it chooses a file to close, closes it and 7372 opens the one wanted, returning its file handle. 7373 7374 2.16.1 Caching functions 7375 ------------------------ 7376 7377 2.16.1.1 `bfd_cache_init' 7378 ......................... 7379 7380 *Synopsis* 7381 bfd_boolean bfd_cache_init (bfd *abfd); 7382 *Description* 7383 Add a newly opened BFD to the cache. 7384 7385 2.16.1.2 `bfd_cache_close' 7386 .......................... 7387 7388 *Synopsis* 7389 bfd_boolean bfd_cache_close (bfd *abfd); 7390 *Description* 7391 Remove the BFD ABFD from the cache.

The third routine takes all the object files and links them 7438 together to create the output file. These routines are designed so 7439 that the linker proper does not need to know anything about the symbols 7440 in the object files that it is linking. The linker merely arranges the 7441 sections as directed by the linker script and lets BFD handle the 7442 details of symbols and relocs. 7443 7444 The second routine and third routines are passed a pointer to a 7445 `struct bfd_link_info' structure (defined in `bfdlink.h') which holds 7446 information relevant to the link, including the linker hash table 7447 (which was created by the first routine) and a set of callback 7448 functions to the linker proper. 7449 7450 The generic linker routines are in `linker.c', and use the header 7451 file `genlink.h'. As of this writing, the only back ends which have 7452 implemented versions of these routines are a.out (in `aoutx.h') and 7453 ECOFF (in `ecoff.c').

This 7471 entry point is called using the target vector of the linker output file. 7472 7473 The `_bfd_link_hash_table_create' entry point must allocate and 7474 initialize an instance of the desired hash table. If the back end does 7475 not require any additional information to be stored with the entries in 7476 the hash table, the entry point may simply create a `struct 7477 bfd_link_hash_table'. Most likely, however, some additional 7478 information will be needed. 7479 7480 For example, with each entry in the hash table the a.out linker 7481 keeps the index the symbol has in the final output file (this index 7482 number is used so that when doing a relocatable link the symbol index 7483 used in the output file can be quickly filled in when copying over a 7484 reloc). The a.out linker code defines the required structures and 7485 functions for a hash table derived from `struct bfd_link_hash_table'. 7486 The a.out linker hash table is created by the function 7487 `NAME(aout,link_hash_table_create)'; it simply allocates space for the 7488 hash table, initializes it, and returns a pointer to it. 7489 7490 When writing the linker routines for a new back end, you will 7491 generally not know exactly which fields will be required until you have 7492 finished. You should simply create a new hash table which defines no 7493 additional fields, and then simply add fields as they become necessary. 7494 7495 7496 File: bfd.info, Node: Adding Symbols to the Hash Table, Next: Performing the Final Link, Prev: Creating a Linker Hash Table, Up: Linker Functions 7497 7498 2.17.2 Adding symbols to the hash table 7499 --------------------------------------- 7500 7501 The linker proper will call the `_bfd_link_add_symbols' entry point for 7502 each object file or archive which is to be linked (typically these are 7503 the files named on the command line, but some may also come from the 7504 linker script). The entry point is responsible for examining the file. 7505 For an object file, BFD must add any relevant symbol information to 7506 the hash table. For an archive, BFD must determine which elements of 7507 the archive should be used and adding them to the link. 7508 7509 The a.out version of this entry point is 7510 `NAME(aout,link_add_symbols)'. 7511 7512 * Menu: 7513 7514 * Differing file formats:: 7515 * Adding symbols from an object file:: 7516 * Adding symbols from an archive:: 7517 7518 7519 File: bfd.info, Node: Differing file formats, Next: Adding symbols from an object file, Prev: Adding Symbols to the Hash Table, Up: Adding Symbols to the Hash Table 7520 7521 2.17.2.1 Differing file formats 7522 ............................... 7523 7524 Normally all the files involved in a link will be of the same format, 7525 but it is also possible to link together different format object files, 7526 and the back end must support that. The `_bfd_link_add_symbols' entry 7527 point is called via the target vector of the file to be added. This 7528 has an important consequence: the function may not assume that the hash 7529 table is the type created by the corresponding 7530 `_bfd_link_hash_table_create' vector. All the `_bfd_link_add_symbols' 7531 function can assume about the hash table is that it is derived from 7532 `struct bfd_link_hash_table'. 7533 7534 Sometimes the `_bfd_link_add_symbols' function must store some 7535 information in the hash table entry to be used by the `_bfd_final_link' 7536 function. In such a case the output bfd xvec must be checked to make 7537 sure that the hash table was created by an object file of the same 7538 format. 7539 7540 The `_bfd_final_link' routine must be prepared to handle a hash 7541 entry without any extra information added by the 7542 `_bfd_link_add_symbols' function. A hash entry without extra 7543 information will also occur when the linker script directs the linker 7544 to create a symbol. Note that, regardless of how a hash table entry is 7545 added, all the fields will be initialized to some sort of null value by 7546 the hash table entry initialization function. 7547 7548 See `ecoff_link_add_externals' for an example of how to check the 7549 output bfd before saving information (in this case, the ECOFF external 7550 symbol debugging information) in a hash table entry. 7551 7552 7553 File: bfd.info, Node: Adding symbols from an object file, Next: Adding symbols from an archive, Prev: Differing file formats, Up: Adding Symbols to the Hash Table 7554 7555 2.17.2.2 Adding symbols from an object file 7556 ........................................... 7557 7558 When the `_bfd_link_add_symbols' routine is passed an object file, it 7559 must add all externally visible symbols in that object file to the hash 7560 table. The actual work of adding the symbol to the hash table is 7561 normally handled by the function `_bfd_generic_link_add_one_symbol'. 7562 The `_bfd_link_add_symbols' routine is responsible for reading all the 7563 symbols from the object file and passing the correct information to 7564 `_bfd_generic_link_add_one_symbol'. 7565 7566 The `_bfd_link_add_symbols' routine should not use 7567 `bfd_canonicalize_symtab' to read the symbols. The point of providing 7568 this routine is to avoid the overhead of converting the symbols into 7569 generic `asymbol' structures. 7570 7571 `_bfd_generic_link_add_one_symbol' handles the details of combining 7572 common symbols, warning about multiple definitions, and so forth. It 7573 takes arguments which describe the symbol to add, notably symbol flags, 7574 a section, and an offset. The symbol flags include such things as 7575 `BSF_WEAK' or `BSF_INDIRECT'. The section is a section in the object 7576 file, or something like `bfd_und_section_ptr' for an undefined symbol 7577 or `bfd_com_section_ptr' for a common symbol. 7578 7579 If the `_bfd_final_link' routine is also going to need to read the 7580 symbol information, the `_bfd_link_add_symbols' routine should save it 7581 somewhere attached to the object file BFD. However, the information 7582 should only be saved if the `keep_memory' field of the `info' argument 7583 is TRUE, so that the `-no-keep-memory' linker switch is effective. 7584 7585 The a.out function which adds symbols from an object file is 7586 `aout_link_add_object_symbols', and most of the interesting work is in 7587 `aout_link_add_symbols'. The latter saves pointers to the hash tables 7588 entries created by `_bfd_generic_link_add_one_symbol' indexed by symbol 7589 number, so that the `_bfd_final_link' routine does not have to call the 7590 hash table lookup routine to locate the entry. 7591 7592 7593 File: bfd.info, Node: Adding symbols from an archive, Prev: Adding symbols from an object file, Up: Adding Symbols to the Hash Table 7594 7595 2.17.2.3 Adding symbols from an archive 7596 ....................................... 7597 7598 When the `_bfd_link_add_symbols' routine is passed an archive, it must 7599 look through the symbols defined by the archive and decide which 7600 elements of the archive should be included in the link. For each such 7601 element it must call the `add_archive_element' linker callback, and it 7602 must add the symbols from the object file to the linker hash table. 7603 7604 In most cases the work of looking through the symbols in the archive 7605 should be done by the `_bfd_generic_link_add_archive_symbols' function. 7606 This function builds a hash table from the archive symbol table and 7607 looks through the list of undefined symbols to see which elements 7608 should be included. `_bfd_generic_link_add_archive_symbols' is passed 7609 a function to call to make the final decision about adding an archive 7610 element to the link and to do the actual work of adding the symbols to 7611 the linker hash table. 7612 7613 The function passed to `_bfd_generic_link_add_archive_symbols' must 7614 read the symbols of the archive element and decide whether the archive 7615 element should be included in the link. If the element is to be 7616 included, the `add_archive_element' linker callback routine must be 7617 called with the element as an argument, and the elements symbols must 7618 be added to the linker hash table just as though the element had itself 7619 been passed to the `_bfd_link_add_symbols' function. 7620 7621 When the a.out `_bfd_link_add_symbols' function receives an archive, 7622 it calls `_bfd_generic_link_add_archive_symbols' passing 7623 `aout_link_check_archive_element' as the function argument. 7624 `aout_link_check_archive_element' calls `aout_link_check_ar_symbols'. 7625 If the latter decides to add the element (an element is only added if 7626 it provides a real, non-common, definition for a previously undefined 7627 or common symbol) it calls the `add_archive_element' callback and then 7628 `aout_link_check_archive_element' calls `aout_link_add_symbols' to 7629 actually add the symbols to the linker hash table. 7630 7631 The ECOFF back end is unusual in that it does not normally call 7632 `_bfd_generic_link_add_archive_symbols', because ECOFF archives already 7633 contain a hash table of symbols. The ECOFF back end searches the 7634 archive itself to avoid the overhead of creating a new hash table. 7635 7636 7637 File: bfd.info, Node: Performing the Final Link, Prev: Adding Symbols to the Hash Table, Up: Linker Functions 7638 7639 2.17.3 Performing the final link 7640 -------------------------------- 7641 7642 When all the input files have been processed, the linker calls the 7643 `_bfd_final_link' entry point of the output BFD. This routine is 7644 responsible for producing the final output file, which has several 7645 aspects. It must relocate the contents of the input sections and copy 7646 the data into the output sections. It must build an output symbol 7647 table including any local symbols from the input files and the global 7648 symbols from the hash table. When producing relocatable output, it must 7649 modify the input relocs and write them into the output file. There may 7650 also be object format dependent work to be done. 7651 7652 The linker will also call the `write_object_contents' entry point 7653 when the BFD is closed. The two entry points must work together in 7654 order to produce the correct output file. 7655 7656 The details of how this works are inevitably dependent upon the 7657 specific object file format. The a.out `_bfd_final_link' routine is 7658 `NAME(aout,final_link)'. 7659 7660 * Menu: 7661 7662 * Information provided by the linker:: 7663 * Relocating the section contents:: 7664 * Writing the symbol table:: 7665 7666 7667 File: bfd.info, Node: Information provided by the linker, Next: Relocating the section contents, Prev: Performing the Final Link, Up: Performing the Final Link 7668 7669 2.17.3.1 Information provided by the linker 7670 ........................................... 7671 7672 Before the linker calls the `_bfd_final_link' entry point, it sets up 7673 some data structures for the function to use. 7674 7675 The `input_bfds' field of the `bfd_link_info' structure will point 7676 to a list of all the input files included in the link. These files are 7677 linked through the `link_next' field of the `bfd' structure. 7678 7679 Each section in the output file will have a list of `link_order' 7680 structures attached to the `map_head.link_order' field (the 7681 `link_order' structure is defined in `bfdlink.h'). These structures 7682 describe how to create the contents of the output section in terms of 7683 the contents of various input sections, fill constants, and, 7684 eventually, other types of information. They also describe relocs that 7685 must be created by the BFD backend, but do not correspond to any input 7686 file; this is used to support -Ur, which builds constructors while 7687 generating a relocatable object file. 7688 7689 7690 File: bfd.info, Node: Relocating the section contents, Next: Writing the symbol table, Prev: Information provided by the linker, Up: Performing the Final Link 7691 7692 2.17.3.2 Relocating the section contents 7693 ........................................ 7694 7695 The `_bfd_final_link' function should look through the `link_order' 7696 structures attached to each section of the output file. Each 7697 `link_order' structure should either be handled specially, or it should 7698 be passed to the function `_bfd_default_link_order' which will do the 7699 right thing (`_bfd_default_link_order' is defined in `linker.c'). 7700 7701 For efficiency, a `link_order' of type `bfd_indirect_link_order' 7702 whose associated section belongs to a BFD of the same format as the 7703 output BFD must be handled specially. This type of `link_order' 7704 describes part of an output section in terms of a section belonging to 7705 one of the input files. The `_bfd_final_link' function should read the 7706 contents of the section and any associated relocs, apply the relocs to 7707 the section contents, and write out the modified section contents. If 7708 performing a relocatable link, the relocs themselves must also be 7709 modified and written out. 7710 7711 The functions `_bfd_relocate_contents' and 7712 `_bfd_final_link_relocate' provide some general support for performing 7713 the actual relocations, notably overflow checking. Their arguments 7714 include information about the symbol the relocation is against and a 7715 `reloc_howto_type' argument which describes the relocation to perform. 7716 These functions are defined in `reloc.c'. 7717 7718 The a.out function which handles reading, relocating, and writing 7719 section contents is `aout_link_input_section'. The actual relocation 7720 is done in `aout_link_input_section_std' and 7721 `aout_link_input_section_ext'. 7722 7723 7724 File: bfd.info, Node: Writing the symbol table, Prev: Relocating the section contents, Up: Performing the Final Link 7725 7726 2.17.3.3 Writing the symbol table 7727 ................................. 7728 7729 The `_bfd_final_link' function must gather all the symbols in the input 7730 files and write them out. It must also write out all the symbols in 7731 the global hash table. This must be controlled by the `strip' and 7732 `discard' fields of the `bfd_link_info' structure. 7733 7734 The local symbols of the input files will not have been entered into 7735 the linker hash table. The `_bfd_final_link' routine must consider 7736 each input file and include the symbols in the output file. It may be 7737 convenient to do this when looking through the `link_order' structures, 7738 or it may be done by stepping through the `input_bfds' list. 7739 7740 The `_bfd_final_link' routine must also traverse the global hash 7741 table to gather all the externally visible symbols. It is possible 7742 that most of the externally visible symbols may be written out when 7743 considering the symbols of each input file, but it is still necessary 7744 to traverse the hash table since the linker script may have defined 7745 some symbols that are not in any of the input files. 7746 7747 The `strip' field of the `bfd_link_info' structure controls which 7748 symbols are written out. The possible values are listed in 7749 `bfdlink.h'. If the value is `strip_some', then the `keep_hash' field 7750 of the `bfd_link_info' structure is a hash table of symbols to keep; 7751 each symbol should be looked up in this hash table, and only symbols 7752 which are present should be included in the output file. 7753 7754 If the `strip' field of the `bfd_link_info' structure permits local 7755 symbols to be written out, the `discard' field is used to further 7756 controls which local symbols are included in the output file. If the 7757 value is `discard_l', then all local symbols which begin with a certain 7758 prefix are discarded; this is controlled by the 7759 `bfd_is_local_label_name' entry point. 7760 7761 The a.out backend handles symbols by calling 7762 `aout_link_write_symbols' on each input BFD and then traversing the 7763 global hash table with the function `aout_link_write_other_symbol'. It 7764 builds a string table while writing out the symbols, which is written 7765 to the output file at the end of `NAME(aout,final_link)'. 7766 7767 2.17.3.4 `bfd_link_split_section' 7768 ................................. 7769 7770 *Synopsis* 7771 bfd_boolean bfd_link_split_section (bfd *abfd, asection *sec); 7772 *Description* 7773 Return nonzero if SEC should be split during a reloceatable or final 7774 link. 7775 #define bfd_link_split_section(abfd, sec) \ 7776 BFD_SEND (abfd, _bfd_link_split_section, (abfd, sec)) 7777 7778 2.17.3.5 `bfd_section_already_linked' 7779 ..................................... 7780 7781 *Synopsis* 7782 void bfd_section_already_linked (bfd *abfd, asection *sec, 7783 struct bfd_link_info *info); 7784 *Description* 7785 Check if SEC has been already linked during a reloceatable or final 7786 link. 7787 #define bfd_section_already_linked(abfd, sec, info) \ 7788 BFD_SEND (abfd, _section_already_linked, (abfd, sec, info)) 7789 7790 2.17.3.6 `bfd_generic_define_common_symbol' 7791 ........................................... 7792 7793 *Synopsis* 7794 bfd_boolean bfd_generic_define_common_symbol 7795 (bfd *output_bfd, struct bfd_link_info *info, 7796 struct bfd_link_hash_entry *h); 7797 *Description* 7798 Convert common symbol H into a defined symbol.

Routines are 7822 provided to initialize a hash table, to free a hash table, to look up a 7823 string in a hash table and optionally create an entry for it, and to 7824 traverse a hash table. There is currently no routine to delete an 7825 string from a hash table. 7826 7827 The basic hash table does not permit any data to be stored with a 7828 string. However, a hash table is designed to present a base class from 7829 which other types of hash tables may be derived. These derived types 7830 may store additional information with the string. Hash tables were 7831 implemented in this way, rather than simply providing a data pointer in 7832 a hash table entry, because they were designed for use by the linker 7833 back ends. The linker may create thousands of hash table entries, and 7834 the overhead of allocating private data and storing and following 7835 pointers becomes noticeable. 7836 7837 The basic hash table code is in `hash.c'. 7838 7839 * Menu: 7840 7841 * Creating and Freeing a Hash Table:: 7842 * Looking Up or Entering a String:: 7843 * Traversing a Hash Table:: 7844 * Deriving a New Hash Table Type:: 7845 7846 7847 File: bfd.info, Node: Creating and Freeing a Hash Table, Next: Looking Up or Entering a String, Prev: Hash Tables, Up: Hash Tables 7848 7849 2.18.1 Creating and freeing a hash table 7850 ---------------------------------------- 7851 7852 To create a hash table, create an instance of a `struct bfd_hash_table' 7853 (defined in `bfd.h') and call `bfd_hash_table_init' (if you know 7854 approximately how many entries you will need, the function 7855 `bfd_hash_table_init_n', which takes a SIZE argument, may be used). 7856 `bfd_hash_table_init' returns `FALSE' if some sort of error occurs. 7857 7858 The function `bfd_hash_table_init' take as an argument a function to 7859 use to create new entries. For a basic hash table, use the function 7860 `bfd_hash_newfunc'. *Note Deriving a New Hash Table Type::, for why 7861 you would want to use a different value for this argument. 7862 7863 `bfd_hash_table_init' will create an objalloc which will be used to 7864 allocate new entries. You may allocate memory on this objalloc using 7865 `bfd_hash_allocate'. 7866 7867 Use `bfd_hash_table_free' to free up all the memory that has been 7868 allocated for a hash table. This will not free up the `struct 7869 bfd_hash_table' itself, which you must provide. 7870 7871 Use `bfd_hash_set_default_size' to set the default size of hash 7872 table to use. 7873 7874 7875 File: bfd.info, Node: Looking Up or Entering a String, Next: Traversing a Hash Table, Prev: Creating and Freeing a Hash Table, Up: Hash Tables 7876 7877 2.18.2 Looking up or entering a string 7878 -------------------------------------- 7879 7880 The function `bfd_hash_lookup' is used both to look up a string in the 7881 hash table and to create a new entry. 7882 7883 If the CREATE argument is `FALSE', `bfd_hash_lookup' will look up a 7884 string. If the string is found, it will returns a pointer to a `struct 7885 bfd_hash_entry'. If the string is not found in the table 7886 `bfd_hash_lookup' will return `NULL'. You should not modify any of the 7887 fields in the returns `struct bfd_hash_entry'. 7888 7889 If the CREATE argument is `TRUE', the string will be entered into 7890 the hash table if it is not already there. Either way a pointer to a 7891 `struct bfd_hash_entry' will be returned, either to the existing 7892 structure or to a newly created one. In this case, a `NULL' return 7893 means that an error occurred. 7894 7895 If the CREATE argument is `TRUE', and a new entry is created, the 7896 COPY argument is used to decide whether to copy the string onto the 7897 hash table objalloc or not. If COPY is passed as `FALSE', you must be 7898 careful not to deallocate or modify the string as long as the hash table 7899 exists. 7900 7901 7902 File: bfd.info, Node: Traversing a Hash Table, Next: Deriving a New Hash Table Type, Prev: Looking Up or Entering a String, Up: Hash Tables 7903 7904 2.18.3 Traversing a hash table 7905 ------------------------------ 7906 7907 The function `bfd_hash_traverse' may be used to traverse a hash table, 7908 calling a function on each element. The traversal is done in a random 7909 order. 7910 7911 `bfd_hash_traverse' takes as arguments a function and a generic 7912 `void *' pointer. The function is called with a hash table entry (a 7913 `struct bfd_hash_entry *') and the generic pointer passed to 7914 `bfd_hash_traverse'. The function must return a `boolean' value, which 7915 indicates whether to continue traversing the hash table. If the 7916 function returns `FALSE', `bfd_hash_traverse' will stop the traversal 7917 and return immediately. 7918 7919 7920 File: bfd.info, Node: Deriving a New Hash Table Type, Prev: Traversing a Hash Table, Up: Hash Tables 7921 7922 2.18.4 Deriving a new hash table type 7923 ------------------------------------- 7924 7925 Many uses of hash tables want to store additional information which 7926 each entry in the hash table. Some also find it convenient to store 7927 additional information with the hash table itself. This may be done 7928 using a derived hash table. 7929 7930 Since C is not an object oriented language, creating a derived hash 7931 table requires sticking together some boilerplate routines with a few 7932 differences specific to the type of hash table you want to create. 7933 7934 An example of a derived hash table is the linker hash table. The 7935 structures for this are defined in `bfdlink.h'. The functions are in 7936 `linker.c'. 7937 7938 You may also derive a hash table from an already derived hash table. 7939 For example, the a.out linker backend code uses a hash table derived 7940 from the linker hash table. 7941 7942 * Menu: 7943 7944 * Define the Derived Structures:: 7945 * Write the Derived Creation Routine:: 7946 * Write Other Derived Routines:: 7947 7948 7949 File: bfd.info, Node: Define the Derived Structures, Next: Write the Derived Creation Routine, Prev: Deriving a New Hash Table Type, Up: Deriving a New Hash Table Type 7950 7951 2.18.4.1 Define the derived structures 7952 ...................................... 7953 7954 You must define a structure for an entry in the hash table, and a 7955 structure for the hash table itself. 7956 7957 The first field in the structure for an entry in the hash table must 7958 be of the type used for an entry in the hash table you are deriving 7959 from. If you are deriving from a basic hash table this is `struct 7960 bfd_hash_entry', which is defined in `bfd.h'. The first field in the 7961 structure for the hash table itself must be of the type of the hash 7962 table you are deriving from itself. If you are deriving from a basic 7963 hash table, this is `struct bfd_hash_table'. 7964 7965 For example, the linker hash table defines `struct 7966 bfd_link_hash_entry' (in `bfdlink.h'). The first field, `root', is of 7967 type `struct bfd_hash_entry'. Similarly, the first field in `struct 7968 bfd_link_hash_table', `table', is of type `struct bfd_hash_table'. 7969 7970 7971 File: bfd.info, Node: Write the Derived Creation Routine, Next: Write Other Derived Routines, Prev: Define the Derived Structures, Up: Deriving a New Hash Table Type 7972 7973 2.18.4.2 Write the derived creation routine 7974 ........................................... 7975 7976 You must write a routine which will create and initialize an entry in 7977 the hash table. This routine is passed as the function argument to 7978 `bfd_hash_table_init'. 7979 7980 In order to permit other hash tables to be derived from the hash 7981 table you are creating, this routine must be written in a standard way. 7982 7983 The first argument to the creation routine is a pointer to a hash 7984 table entry. This may be `NULL', in which case the routine should 7985 allocate the right amount of space. Otherwise the space has already 7986 been allocated by a hash table type derived from this one. 7987 7988 After allocating space, the creation routine must call the creation 7989 routine of the hash table type it is derived from, passing in a pointer 7990 to the space it just allocated. This will initialize any fields used 7991 by the base hash table. 7992 7993 Finally the creation routine must initialize any local fields for 7994 the new hash table type. 7995 7996 Here is a boilerplate example of a creation routine. FUNCTION_NAME 7997 is the name of the routine. ENTRY_TYPE is the type of an entry in the 7998 hash table you are creating. BASE_NEWFUNC is the name of the creation 7999 routine of the hash table type your hash table is derived from. 8000 8001 struct bfd_hash_entry * 8002 FUNCTION_NAME (struct bfd_hash_entry *entry, 8003 struct bfd_hash_table *table, 8004 const char *string) 8005 { 8006 struct ENTRY_TYPE *ret = (ENTRY_TYPE *) entry; 8007 8008 /* Allocate the structure if it has not already been allocated by a 8009 derived class. */ 8010 if (ret == NULL) 8011 { 8012 ret = bfd_hash_allocate (table, sizeof (* ret)); 8013 if (ret == NULL) 8014 return NULL; 8015 } 8016 8017 /* Call the allocation method of the base class. */ 8018 ret = ((ENTRY_TYPE *) 8019 BASE_NEWFUNC ((struct bfd_hash_entry *) ret, table, string)); 8020 8021 /* Initialize the local fields here. */ 8022 8023 return (struct bfd_hash_entry *) ret; 8024 } 8025 *Description* 8026 The creation routine for the linker hash table, which is in `linker.c', 8027 looks just like this example. FUNCTION_NAME is 8028 `_bfd_link_hash_newfunc'. ENTRY_TYPE is `struct bfd_link_hash_entry'. 8029 BASE_NEWFUNC is `bfd_hash_newfunc', the creation routine for a basic 8030 hash table. 8031 8032 `_bfd_link_hash_newfunc' also initializes the local fields in a 8033 linker hash table entry: `type', `written' and `next'. 8034 8035 8036 File: bfd.info, Node: Write Other Derived Routines, Prev: Write the Derived Creation Routine, Up: Deriving a New Hash Table Type 8037 8038 2.18.4.3 Write other derived routines 8039 ..................................... 8040 8041 You will want to write other routines for your new hash table, as well. 8042 8043 You will want an initialization routine which calls the 8044 initialization routine of the hash table you are deriving from and 8045 initializes any other local fields. For the linker hash table, this is 8046 `_bfd_link_hash_table_init' in `linker.c'. 8047 8048 You will want a lookup routine which calls the lookup routine of the 8049 hash table you are deriving from and casts the result. The linker hash 8050 table uses `bfd_link_hash_lookup' in `linker.c' (this actually takes an 8051 additional argument which it uses to decide how to return the looked up 8052 value). 8053 8054 You may want a traversal routine. This should just call the 8055 traversal routine of the hash table you are deriving from with 8056 appropriate casts. The linker hash table uses `bfd_link_hash_traverse' 8057 in `linker.c'. 8058 8059 These routines may simply be defined as macros. For example, the 8060 a.out backend linker hash table, which is derived from the linker hash 8061 table, uses macros for the lookup and traversal routines. These are 8062 `aout_link_hash_lookup' and `aout_link_hash_traverse' in aoutx.h. 8063 8064 8065 File: bfd.info, Node: BFD back ends, Next: GNU Free Documentation License, Prev: BFD front end, Up: Top 8066 8067 3 BFD back ends 8068 *************** 8069 8070 * Menu: 8071 8072 * What to Put Where:: 8073 * aout :: a.out backends 8074 * coff :: coff backends 8075 * elf :: elf backends 8076 * mmo :: mmo backend 8077 8078 8079 File: bfd.info, Node: What to Put Where, Next: aout, Prev: BFD back ends, Up: BFD back ends 8080 8081 3.1 What to Put Where 8082 ===================== 8083 8084 All of BFD lives in one directory. 8085 8086 8087 File: bfd.info, Node: aout, Next: coff, Prev: What to Put Where, Up: BFD back ends 8088 8089 3.2 a.out backends 8090 ================== 8091 8092 *Description* 8093 BFD supports a number of different flavours of a.out format, though the 8094 major differences are only the sizes of the structures on disk, and the 8095 shape of the relocation information. 8096 8097 The support is split into a basic support file `aoutx.h' and other 8098 files which derive functions from the base. One derivation file is 8099 `aoutf1.h' (for a.out flavour 1), and adds to the basic a.out functions 8100 support for sun3, sun4, 386 and 29k a.out files, to create a target 8101 jump vector for a specific target. 8102 8103 This information is further split out into more specific files for 8104 each machine, including `sunos.c' for sun3 and sun4, `newsos3.c' for 8105 the Sony NEWS, and `demo64.c' for a demonstration of a 64 bit a.out 8106 format. 8107 8108 The base file `aoutx.h' defines general mechanisms for reading and 8109 writing records to and from disk and various other methods which BFD 8110 requires. It is included by `aout32.c' and `aout64.c' to form the names 8111 `aout_32_swap_exec_header_in', `aout_64_swap_exec_header_in', etc. 8112 8113 As an example, this is what goes on to make the back end for a sun4, 8114 from `aout32.c': 8115 8116 #define ARCH_SIZE 32 8117 #include "aoutx.h" 8118 8119 Which exports names: 8120 8121 ... 8122 aout_32_canonicalize_reloc 8123 aout_32_find_nearest_line 8124 aout_32_get_lineno 8125 aout_32_get_reloc_upper_bound 8126 ... 8127 8128 from `sunos.c': 8129 8130 #define TARGET_NAME "a.out-sunos-big" 8131 #define VECNAME sunos_big_vec 8132 #include "aoutf1.h" 8133 8134 requires all the names from `aout32.c', and produces the jump vector 8135 8136 sunos_big_vec 8137 8138 The file `host-aout.c' is a special case. It is for a large set of 8139 hosts that use "more or less standard" a.out files, and for which 8140 cross-debugging is not interesting. It uses the standard 32-bit a.out 8141 support routines, but determines the file offsets and addresses of the 8142 text, data, and BSS sections, the machine architecture and machine 8143 type, and the entry point address, in a host-dependent manner. Once 8144 these values have been determined, generic code is used to handle the 8145 object file. 8146 8147 When porting it to run on a new system, you must supply: 8148 8149 HOST_PAGE_SIZE 8150 HOST_SEGMENT_SIZE 8151 HOST_MACHINE_ARCH (optional) 8152 HOST_MACHINE_MACHINE (optional) 8153 HOST_TEXT_START_ADDR 8154 HOST_STACK_END_ADDR 8155 8156 in the file `../include/sys/h-XXX.h' (for your host). These values, 8157 plus the structures and macros defined in `a.out.h' on your host 8158 system, will produce a BFD target that will access ordinary a.out files 8159 on your host. To configure a new machine to use `host-aout.c', specify: 8160 8161 TDEFAULTS = -DDEFAULT_VECTOR=host_aout_big_vec 8162 TDEPFILES= host-aout.o trad-core.o 8163 8164 in the `config/XXX.mt' file, and modify `configure.in' to use the 8165 `XXX.mt' file (by setting "`bfd_target=XXX'") when your configuration 8166 is selected. 8167 8168 3.2.1 Relocations 8169 ----------------- 8170 8171 *Description* 8172 The file `aoutx.h' provides for both the _standard_ and _extended_ 8173 forms of a.out relocation records. 8174 8175 The standard records contain only an address, a symbol index, and a 8176 type field. The extended records (used on 29ks and sparcs) also have a 8177 full integer for an addend. 8178 8179 3.2.2 Internal entry points 8180 --------------------------- 8181 8182 *Description* 8183 `aoutx.h' exports several routines for accessing the contents of an 8184 a.out file, which are gathered and exported in turn by various format 8185 specific files (eg sunos.c). 8186 8187 3.2.2.1 `aout_SIZE_swap_exec_header_in' 8188 ....................................... 8189 8190 *Synopsis* 8191 void aout_SIZE_swap_exec_header_in, 8192 (bfd *abfd, 8193 struct external_exec *bytes, 8194 struct internal_exec *execp); 8195 *Description* 8196 Swap the information in an executable header RAW_BYTES taken from a raw 8197 byte stream memory image into the internal exec header structure EXECP. 8198 8199 3.2.2.2 `aout_SIZE_swap_exec_header_out' 8200 ........................................ 8201 8202 *Synopsis* 8203 void aout_SIZE_swap_exec_header_out 8204 (bfd *abfd, 8205 struct internal_exec *execp, 8206 struct external_exec *raw_bytes); 8207 *Description* 8208 Swap the information in an internal exec header structure EXECP into 8209 the buffer RAW_BYTES ready for writing to disk. 8210 8211 3.2.2.3 `aout_SIZE_some_aout_object_p' 8212 ...................................... 8213 8214 *Synopsis* 8215 const bfd_target *aout_SIZE_some_aout_object_p 8216 (bfd *abfd, 8217 struct internal_exec *execp, 8218 const bfd_target *(*callback_to_real_object_p) (bfd *)); 8219 *Description* 8220 Some a.out variant thinks that the file open in ABFD checking is an 8221 a.out file.

The major 8280 differences between formats are the sizes and alignments of fields in 8281 structures on disk, and the occasional extra field. 8282 8283 Coff in all its varieties is implemented with a few common files and 8284 a number of implementation specific files. For example, The 88k bcs 8285 coff format is implemented in the file `coff-m88k.c'. This file 8286 `#include's `coff/m88k.h' which defines the external structure of the 8287 coff format for the 88k, and `coff/internal.h' which defines the 8288 internal structure. `coff-m88k.c' also defines the relocations used by 8289 the 88k format *Note Relocations::. 8290 8291 The Intel i960 processor version of coff is implemented in 8292 `coff-i960.c'. This file has the same structure as `coff-m88k.c', 8293 except that it includes `coff/i960.h' rather than `coff-m88k.h'. 8294 8295 3.3.1 Porting to a new version of coff 8296 -------------------------------------- 8297 8298 The recommended method is to select from the existing implementations 8299 the version of coff which is most like the one you want to use. For 8300 example, we'll say that i386 coff is the one you select, and that your 8301 coff flavour is called foo. Copy `i386coff.c' to `foocoff.c', copy 8302 `../include/coff/i386.h' to `../include/coff/foo.h', and add the lines 8303 to `targets.c' and `Makefile.in' so that your new back end is used. 8304 Alter the shapes of the structures in `../include/coff/foo.h' so that 8305 they match what you need. You will probably also have to add `#ifdef's 8306 to the code in `coff/internal.h' and `coffcode.h' if your version of 8307 coff is too wild. 8308 8309 You can verify that your new BFD backend works quite simply by 8310 building `objdump' from the `binutils' directory, and making sure that 8311 its version of what's going on and your host system's idea (assuming it 8312 has the pretty standard coff dump utility, usually called `att-dump' or 8313 just `dump') are the same. Then clean up your code, and send what 8314 you've done to Cygnus. Then your stuff will be in the next release, and 8315 you won't have to keep integrating it. 8316 8317 3.3.2 How the coff backend works 8318 -------------------------------- 8319 8320 3.3.2.1 File layout 8321 ................... 8322 8323 The Coff backend is split into generic routines that are applicable to 8324 any Coff target and routines that are specific to a particular target. 8325 The target-specific routines are further split into ones which are 8326 basically the same for all Coff targets except that they use the 8327 external symbol format or use different values for certain constants. 8328 8329 The generic routines are in `coffgen.c'. These routines work for 8330 any Coff target. They use some hooks into the target specific code; 8331 the hooks are in a `bfd_coff_backend_data' structure, one of which 8332 exists for each target. 8333 8334 The essentially similar target-specific routines are in 8335 `coffcode.h'. This header file includes executable C code. The 8336 various Coff targets first include the appropriate Coff header file, 8337 make any special defines that are needed, and then include `coffcode.h'. 8338 8339 Some of the Coff targets then also have additional routines in the 8340 target source file itself. 8341 8342 For example, `coff-i960.c' includes `coff/internal.h' and 8343 `coff/i960.h'. It then defines a few constants, such as `I960', and 8344 includes `coffcode.h'. Since the i960 has complex relocation types, 8345 `coff-i960.c' also includes some code to manipulate the i960 relocs. 8346 This code is not in `coffcode.h' because it would not be used by any 8347 other target. 8348 8349 3.3.2.2 Coff long section names 8350 ............................... 8351 8352 In the standard Coff object format, section names are limited to the 8353 eight bytes available in the `s_name' field of the `SCNHDR' section 8354 header structure. The format requires the field to be NUL-padded, but 8355 not necessarily NUL-terminated, so the longest section names permitted 8356 are a full eight characters. 8357 8358 The Microsoft PE variants of the Coff object file format add an 8359 extension to support the use of long section names. This extension is 8360 defined in section 4 of the Microsoft PE/COFF specification (rev 8.1). 8361 If a section name is too long to fit into the section header's `s_name' 8362 field, it is instead placed into the string table, and the `s_name' 8363 field is filled with a slash ("/") followed by the ASCII decimal 8364 representation of the offset of the full name relative to the string 8365 table base. 8366 8367 Note that this implies that the extension can only be used in object 8368 files, as executables do not contain a string table. The standard 8369 specifies that long section names from objects emitted into executable 8370 images are to be truncated. 8371 8372 However, as a GNU extension, BFD can generate executable images that 8373 contain a string table and long section names. This would appear to be 8374 technically valid, as the standard only says that Coff debugging 8375 information is deprecated, not forbidden, and in practice it works, 8376 although some tools that parse PE files expecting the MS standard 8377 format may become confused; `PEview' is one known example. 8378 8379 The functionality is supported in BFD by code implemented under the 8380 control of the macro `COFF_LONG_SECTION_NAMES'. If not defined, the 8381 format does not support long section names in any way. If defined, it 8382 is used to initialise a flag, `_bfd_coff_long_section_names', and a 8383 hook function pointer, `_bfd_coff_set_long_section_names', in the Coff 8384 backend data structure. The flag controls the generation of long 8385 section names in output BFDs at runtime; if it is false, as it will be 8386 by default when generating an executable image, long section names are 8387 truncated; if true, the long section names extension is employed. The 8388 hook points to a function that allows the value of the flag to be 8389 altered at runtime, on formats that support long section names at all; 8390 on other formats it points to a stub that returns an error indication. 8391 With input BFDs, the flag is set according to whether any long section 8392 names are detected while reading the section headers. For a completely 8393 new BFD, the flag is set to the default for the target format. This 8394 information can be used by a client of the BFD library when deciding 8395 what output format to generate, and means that a BFD that is opened for 8396 read and subsequently converted to a writeable BFD and modified 8397 in-place will retain whatever format it had on input. 8398 8399 If `COFF_LONG_SECTION_NAMES' is simply defined (blank), or is 8400 defined to the value "1", then long section names are enabled by 8401 default; if it is defined to the value zero, they are disabled by 8402 default (but still accepted in input BFDs). The header `coffcode.h' 8403 defines a macro, `COFF_DEFAULT_LONG_SECTION_NAMES', which is used in 8404 the backends to initialise the backend data structure fields 8405 appropriately; see the comments for further detail. 8406 8407 3.3.2.3 Bit twiddling 8408 ..................... 8409 8410 Each flavour of coff supported in BFD has its own header file 8411 describing the external layout of the structures. There is also an 8412 internal description of the coff layout, in `coff/internal.h'. A major 8413 function of the coff backend is swapping the bytes and twiddling the 8414 bits to translate the external form of the structures into the normal 8415 internal form. This is all performed in the `bfd_swap'_thing_direction 8416 routines. Some elements are different sizes between different versions 8417 of coff; it is the duty of the coff version specific include file to 8418 override the definitions of various packing routines in `coffcode.h'. 8419 E.g., the size of line number entry in coff is sometimes 16 bits, and 8420 sometimes 32 bits. `#define'ing `PUT_LNSZ_LNNO' and `GET_LNSZ_LNNO' 8421 will select the correct one. No doubt, some day someone will find a 8422 version of coff which has a varying field size not catered to at the 8423 moment. To port BFD, that person will have to add more `#defines'. 8424 Three of the bit twiddling routines are exported to `gdb'; 8425 `coff_swap_aux_in', `coff_swap_sym_in' and `coff_swap_lineno_in'. `GDB' 8426 reads the symbol table on its own, but uses BFD to fix things up. More 8427 of the bit twiddlers are exported for `gas'; `coff_swap_aux_out', 8428 `coff_swap_sym_out', `coff_swap_lineno_out', `coff_swap_reloc_out', 8429 `coff_swap_filehdr_out', `coff_swap_aouthdr_out', 8430 `coff_swap_scnhdr_out'. `Gas' currently keeps track of all the symbol 8431 table and reloc drudgery itself, thereby saving the internal BFD 8432 overhead, but uses BFD to swap things on the way out, making cross 8433 ports much safer. Doing so also allows BFD (and thus the linker) to 8434 use the same header files as `gas', which makes one avenue to disaster 8435 disappear. 8436 8437 3.3.2.4 Symbol reading 8438 ...................... 8439 8440 The simple canonical form for symbols used by BFD is not rich enough to 8441 keep all the information available in a coff symbol table. The back end 8442 gets around this problem by keeping the original symbol table around, 8443 "behind the scenes". 8444 8445 When a symbol table is requested (through a call to 8446 `bfd_canonicalize_symtab'), a request gets through to 8447 `coff_get_normalized_symtab'. This reads the symbol table from the coff 8448 file and swaps all the structures inside into the internal form. It 8449 also fixes up all the pointers in the table (represented in the file by 8450 offsets from the first symbol in the table) into physical pointers to 8451 elements in the new internal table. This involves some work since the 8452 meanings of fields change depending upon context: a field that is a 8453 pointer to another structure in the symbol table at one moment may be 8454 the size in bytes of a structure at the next. Another pass is made 8455 over the table. All symbols which mark file names (`C_FILE' symbols) 8456 are modified so that the internal string points to the value in the 8457 auxent (the real filename) rather than the normal text associated with 8458 the symbol (`".file"'). 8459 8460 At this time the symbol names are moved around. Coff stores all 8461 symbols less than nine characters long physically within the symbol 8462 table; longer strings are kept at the end of the file in the string 8463 table. This pass moves all strings into memory and replaces them with 8464 pointers to the strings. 8465 8466 The symbol table is massaged once again, this time to create the 8467 canonical table used by the BFD application. Each symbol is inspected 8468 in turn, and a decision made (using the `sclass' field) about the 8469 various flags to set in the `asymbol'. *Note Symbols::. The generated 8470 canonical table shares strings with the hidden internal symbol table. 8471 8472 Any linenumbers are read from the coff file too, and attached to the 8473 symbols which own the functions the linenumbers belong to. 8474 8475 3.3.2.5 Symbol writing 8476 ...................... 8477 8478 Writing a symbol to a coff file which didn't come from a coff file will 8479 lose any debugging information. The `asymbol' structure remembers the 8480 BFD from which the symbol was taken, and on output the back end makes 8481 sure that the same destination target as source target is present. 8482 8483 When the symbols have come from a coff file then all the debugging 8484 information is preserved. 8485 8486 Symbol tables are provided for writing to the back end in a vector 8487 of pointers to pointers. This allows applications like the linker to 8488 accumulate and output large symbol tables without having to do too much 8489 byte copying. 8490 8491 This function runs through the provided symbol table and patches 8492 each symbol marked as a file place holder (`C_FILE') to point to the 8493 next file place holder in the list. It also marks each `offset' field 8494 in the list with the offset from the first symbol of the current symbol. 8495 8496 Another function of this procedure is to turn the canonical value 8497 form of BFD into the form used by coff. Internally, BFD expects symbol 8498 values to be offsets from a section base; so a symbol physically at 8499 0x120, but in a section starting at 0x100, would have the value 0x20. 8500 Coff expects symbols to contain their final value, so symbols have 8501 their values changed at this point to reflect their sum with their 8502 owning section. This transformation uses the `output_section' field of 8503 the `asymbol''s `asection' *Note Sections::. 8504 8505 * `coff_mangle_symbols' 8506 This routine runs though the provided symbol table and uses the 8507 offsets generated by the previous pass and the pointers generated when 8508 the symbol table was read in to create the structured hierarchy 8509 required by coff. It changes each pointer to a symbol into the index 8510 into the symbol table of the asymbol. 8511 8512 * `coff_write_symbols' 8513 This routine runs through the symbol table and patches up the 8514 symbols from their internal form into the coff way, calls the bit 8515 twiddlers, and writes out the table to the file. 8516 8517 3.3.2.6 `coff_symbol_type' 8518 .......................... 8519 8520 *Description* 8521 The hidden information for an `asymbol' is described in a 8522 `combined_entry_type': 8523 8524 8525 typedef struct coff_ptr_struct 8526 { 8527 /* Remembers the offset from the first symbol in the file for 8528 this symbol.

write relocations, the back end steps though the canonical 8880 relocation table and create an `internal_reloc'. The symbol index to 8881 use is removed from the `offset' field in the symbol table supplied. 8882 The address comes directly from the sum of the section base address and 8883 the relocation offset; the type is dug directly from the howto field. 8884 Then the `internal_reloc' is swapped into the shape of an 8885 `external_reloc' and written out to disk. 8886 8887 3.3.2.9 Reading linenumbers 8888 ........................... 8889 8890 Creating the linenumber table is done by reading in the entire coff 8891 linenumber table, and creating another table for internal use. 8892 8893 A coff linenumber table is structured so that each function is 8894 marked as having a line number of 0. Each line within the function is 8895 an offset from the first line in the function. The base of the line 8896 number information for the table is stored in the symbol associated 8897 with the function. 8898 8899 Note: The PE format uses line number 0 for a flag indicating a new 8900 source file. 8901 8902 The information is copied from the external to the internal table, 8903 and each symbol which marks a function is marked by pointing its... 8904 8905 How does this work ? 8906 8907 3.3.2.10 Reading relocations 8908 ............................ 8909 8910 Coff relocations are easily transformed into the internal BFD form 8911 (`arelent'). 8912 8913 Reading a coff relocation table is done in the following stages: 8914 8915 * Read the entire coff relocation table into memory. 8916 8917 * Process each relocation in turn; first swap it from the external 8918 to the internal form. 8919 8920 * Turn the symbol referenced in the relocation's symbol index into a 8921 pointer into the canonical symbol table. This table is the same 8922 as the one returned by a call to `bfd_canonicalize_symtab'. The 8923 back end will call that routine and save the result if a 8924 canonicalization hasn't been done. 8925 8926 * The reloc index is turned into a pointer to a howto structure, in 8927 a back end specific way. For instance, the 386 and 960 use the 8928 `r_type' to directly produce an index into a howto table vector; 8929 the 88k subtracts a number from the `r_type' field and creates an 8930 addend field. 8931 8932 8933 File: bfd.info, Node: elf, Next: mmo, Prev: coff, Up: BFD back ends 8934 8935 3.4 ELF backends 8936 ================ 8937 8938 BFD support for ELF formats is being worked on. Currently, the best 8939 supported back ends are for sparc and i386 (running svr4 or Solaris 2). 8940 8941 Documentation of the internals of the support code still needs to be 8942 written. The code is changing quickly enough that we haven't bothered 8943 yet. 8944 8945 8946 File: bfd.info, Node: mmo, Prev: elf, Up: BFD back ends 8947 8948 3.5 mmo backend 8949 =============== 8950 8951 The mmo object format is used exclusively together with Professor 8952 Donald E. Knuth's educational 64-bit processor MMIX. The simulator 8953 `mmix' which is available at 8954 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz' 8955 understands this format. That package also includes a combined 8956 assembler and linker called `mmixal'. The mmo format has no advantages 8957 feature-wise compared to e.g. ELF. It is a simple non-relocatable 8958 object format with no support for archives or debugging information, 8959 except for symbol value information and line numbers (which is not yet 8960 implemented in BFD). See 8961 `http://www-cs-faculty.stanford.edu/~knuth/mmix.html' for more 8962 information about MMIX. The ELF format is used for intermediate object 8963 files in the BFD implementation. 8964 8965 * Menu: 8966 8967 * File layout:: 8968 * Symbol-table:: 8969 * mmo section mapping:: 8970 8971 8972 File: bfd.info, Node: File layout, Next: Symbol-table, Prev: mmo, Up: mmo 8973 8974 3.5.1 File layout 8975 ----------------- 8976 8977 The mmo file contents is not partitioned into named sections as with 8978 e.g. ELF. Memory areas is formed by specifying the location of the 8979 data that follows. Only the memory area `0x0000...00' to `0x01ff...ff' 8980 is executable, so it is used for code (and constants) and the area 8981 `0x2000...00' to `0x20ff...ff' is used for writable data. *Note mmo 8982 section mapping::. 8983 8984 There is provision for specifying "special data" of 65536 different 8985 types. We use type 80 (decimal), arbitrarily chosen the same as the 8986 ELF `e_machine' number for MMIX, filling it with section information 8987 normally found in ELF objects. *Note mmo section mapping::. 8988 8989 Contents is entered as 32-bit words, xor:ed over previous contents, 8990 always zero-initialized. A word that starts with the byte `0x98' forms 8991 a command called a `lopcode', where the next byte distinguished between 8992 the thirteen lopcodes. The two remaining bytes, called the `Y' and `Z' 8993 fields, or the `YZ' field (a 16-bit big-endian number), are used for 8994 various purposes different for each lopcode. As documented in 8995 `http://www-cs-faculty.stanford.edu/~knuth/mmixal-intro.ps.gz', the 8996 lopcodes are: 8997 8998 `lop_quote' 8999 0x98000001. The next word is contents, regardless of whether it 9000 starts with 0x98 or not. 9001 9002 `lop_loc' 9003 0x9801YYZZ, where `Z' is 1 or 2. This is a location directive, 9004 setting the location for the next data to the next 32-bit word 9005 (for Z = 1) or 64-bit word (for Z = 2), plus Y * 2^56. Normally 9006 `Y' is 0 for the text segment and 2 for the data segment. 9007 9008 `lop_skip' 9009 0x9802YYZZ. Increase the current location by `YZ' bytes. 9010 9011 `lop_fixo' 9012 0x9803YYZZ, where `Z' is 1 or 2. Store the current location as 64 9013 bits into the location pointed to by the next 32-bit (Z = 1) or 9014 64-bit (Z = 2) word, plus Y * 2^56. 9015 9016 `lop_fixr' 9017 0x9804YYZZ. `YZ' is stored into the current location plus 2 - 4 * 9018 YZ. 9019 9020 `lop_fixrx' 9021 0x980500ZZ. `Z' is 16 or 24. A value `L' derived from the 9022 following 32-bit word are used in a manner similar to `YZ' in 9023 lop_fixr: it is xor:ed into the current location minus 4 * L. The 9024 first byte of the word is 0 or 1. If it is 1, then L = (LOWEST 24 9025 BITS OF WORD) - 2^Z, if 0, then L = (LOWEST 24 BITS OF WORD). 9026 9027 `lop_file' 9028 0x9806YYZZ. `Y' is the file number, `Z' is count of 32-bit words. 9029 Set the file number to `Y' and the line counter to 0. The next Z 9030 * 4 bytes contain the file name, padded with zeros if the count is 9031 not a multiple of four. The same `Y' may occur multiple times, 9032 but `Z' must be 0 for all but the first occurrence. 9033 9034 `lop_line' 9035 0x9807YYZZ. `YZ' is the line number. Together with lop_file, it 9036 forms the source location for the next 32-bit word. Note that for 9037 each non-lopcode 32-bit word, line numbers are assumed incremented 9038 by one. 9039 9040 `lop_spec' 9041 0x9808YYZZ. `YZ' is the type number. Data until the next lopcode 9042 other than lop_quote forms special data of type `YZ'. *Note mmo 9043 section mapping::. 9044 9045 Other types than 80, (or type 80 with a content that does not 9046 parse) is stored in sections named `.MMIX.spec_data.N' where N is 9047 the `YZ'-type. The flags for such a sections say not to allocate 9048 or load the data. The vma is 0. Contents of multiple occurrences 9049 of special data N is concatenated to the data of the previous 9050 lop_spec Ns. The location in data or code at which the lop_spec 9051 occurred is lost. 9052 9053 `lop_pre' 9054 0x980901ZZ. The first lopcode in a file. The `Z' field forms the 9055 length of header information in 32-bit words, where the first word 9056 tells the time in seconds since `00:00:00 GMT Jan 1 1970'. 9057 9058 `lop_post' 9059 0x980a00ZZ. Z > 32. This lopcode follows after all 9060 content-generating lopcodes in a program. The `Z' field denotes 9061 the value of `rG' at the beginning of the program. The following 9062 256 - Z big-endian 64-bit words are loaded into global registers 9063 `$G' ... `$255'. 9064 9065 `lop_stab' 9066 0x980b0000. The next-to-last lopcode in a program. Must follow 9067 immediately after the lop_post lopcode and its data. After this 9068 lopcode follows all symbols in a compressed format (*note 9069 Symbol-table::). 9070 9071 `lop_end' 9072 0x980cYYZZ. The last lopcode in a program. It must follow the 9073 lop_stab lopcode and its data. The `YZ' field contains the number 9074 of 32-bit words of symbol table information after the preceding 9075 lop_stab lopcode. 9076 9077 Note that the lopcode "fixups"; `lop_fixr', `lop_fixrx' and 9078 `lop_fixo' are not generated by BFD, but are handled. They are 9079 generated by `mmixal'. 9080 9081 This trivial one-label, one-instruction file: 9082 9083 :Main TRAP 1,2,3 9084 9085 can be represented this way in mmo: 9086 9087 0x98090101 - lop_pre, one 32-bit word with timestamp. 9088 <timestamp> 9089 0x98010002 - lop_loc, text segment, using a 64-bit address. 9090 Note that mmixal does not emit this for the file above. 9091 0x00000000 - Address, high 32 bits. 9092 0x00000000 - Address, low 32 bits. 9093 0x98060002 - lop_file, 2 32-bit words for file-name. 9094 0x74657374 - "test" 9095 0x2e730000 - ".s\0\0" 9096 0x98070001 - lop_line, line 1. 9097 0x00010203 - TRAP 1,2,3 9098 0x980a00ff - lop_post, setting $255 to 0. 9099 0x00000000 9100 0x00000000 9101 0x980b0000 - lop_stab for ":Main" = 0, serial 1. 9102 0x203a4040 *Note Symbol-table::. 9103 0x10404020 9104 0x4d206120 9105 0x69016e00 9106 0x81000000 9107 0x980c0005 - lop_end; symbol table contained five 32-bit words. 9108 9109 9110 File: bfd.info, Node: Symbol-table, Next: mmo section mapping, Prev: File layout, Up: mmo 9111 9112 3.5.2 Symbol table format 9113 ------------------------- 9114 9115 From mmixal.w (or really, the generated mmixal.tex) in 9116 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'): 9117 "Symbols are stored and retrieved by means of a `ternary search trie', 9118 following ideas of Bentley and Sedgewick. (See ACM-SIAM Symp. on 9119 Discrete Algorithms `8' (1997), 360-369; R.Sedgewick, `Algorithms in C' 9120 (Reading, Mass. Addison-Wesley, 1998), `15.4'.) Each trie node stores 9121 a character, and there are branches to subtries for the cases where a 9122 given character is less than, equal to, or greater than the character 9123 in the trie. There also is a pointer to a symbol table entry if a 9124 symbol ends at the current node." 9125 9126 So it's a tree encoded as a stream of bytes. The stream of bytes 9127 acts on a single virtual global symbol, adding and removing characters 9128 and signalling complete symbol points. Here, we read the stream and 9129 create symbols at the completion points. 9130 9131 First, there's a control byte `m'. If any of the listed bits in `m' 9132 is nonzero, we execute what stands at the right, in the listed order: 9133 9134 (MMO3_LEFT) 9135 0x40 - Traverse left trie. 9136 (Read a new command byte and recurse.) 9137 9138 (MMO3_SYMBITS) 9139 0x2f - Read the next byte as a character and store it in the 9140 current character position; increment character position. 9141 Test the bits of `m': 9142 9143 (MMO3_WCHAR) 9144 0x80 - The character is 16-bit (so read another byte, 9145 merge into current character. 9146 9147 (MMO3_TYPEBITS) 9148 0xf - We have a complete symbol; parse the type, value 9149 and serial number and do what should be done 9150 with a symbol. The type and length information 9151 is in j = (m & 0xf). 9152 9153 (MMO3_REGQUAL_BITS) 9154 j == 0xf: A register variable. The following 9155 byte tells which register. 9156 j <= 8: An absolute symbol. Read j bytes as the 9157 big-endian number the symbol equals. 9158 A j = 2 with two zero bytes denotes an 9159 unknown symbol. 9160 j > 8: As with j <= 8, but add (0x20 << 56) 9161 to the value in the following j - 8 9162 bytes. 9163 9164 Then comes the serial number, as a variant of 9165 uleb128, but better named ubeb128: 9166 Read bytes and shift the previous value left 7 9167 (multiply by 128). Add in the new byte, repeat 9168 until a byte has bit 7 set. The serial number 9169 is the computed value minus 128. 9170 9171 (MMO3_MIDDLE) 9172 0x20 - Traverse middle trie. (Read a new command byte 9173 and recurse.) Decrement character position. 9174 9175 (MMO3_RIGHT) 9176 0x10 - Traverse right trie. (Read a new command byte and 9177 recurse.) 9178 9179 Let's look again at the `lop_stab' for the trivial file (*note File 9180 layout::). 9181 9182 0x980b0000 - lop_stab for ":Main" = 0, serial 1. 9183 0x203a4040 9184 0x10404020 9185 0x4d206120 9186 0x69016e00 9187 0x81000000 9188 9189 This forms the trivial trie (note that the path between ":" and "M" 9190 is redundant): 9191 9192 203a ":" 9193 40 / 9194 40 / 9195 10 \ 9196 40 / 9197 40 / 9198 204d "M" 9199 2061 "a" 9200 2069 "i" 9201 016e "n" is the last character in a full symbol, and 9202 with a value represented in one byte. 9203 00 The value is 0. 9204 81 The serial number is 1. 9205 9206 9207 File: bfd.info, Node: mmo section mapping, Prev: Symbol-table, Up: mmo 9208 9209 3.5.3 mmo section mapping 9210 ------------------------- 9211 9212 The implementation in BFD uses special data type 80 (decimal) to 9213 encapsulate and describe named sections, containing e.g. debug 9214 information. If needed, any datum in the encapsulation will be quoted 9215 using lop_quote. First comes a 32-bit word holding the number of 9216 32-bit words containing the zero-terminated zero-padded segment name. 9217 After the name there's a 32-bit word holding flags describing the 9218 section type. Then comes a 64-bit big-endian word with the section 9219 length (in bytes), then another with the section start address. 9220 Depending on the type of section, the contents might follow, 9221 zero-padded to 32-bit boundary. For a loadable section (such as data 9222 or code), the contents might follow at some later point, not 9223 necessarily immediately, as a lop_loc with the same start address as in 9224 the section description, followed by the contents. This in effect 9225 forms a descriptor that must be emitted before the actual contents. 9226 Sections described this way must not overlap. 9227 9228 For areas that don't have such descriptors, synthetic sections are 9229 formed by BFD. Consecutive contents in the two memory areas 9230 `0x0000...00' to `0x01ff...ff' and `0x2000...00' to `0x20ff...ff' are 9231 entered in sections named `.text' and `.data' respectively. If an area 9232 is not otherwise described, but would together with a neighboring lower 9233 area be less than `0x40000000' bytes long, it is joined with the lower 9234 area and the gap is zero-filled. For other cases, a new section is 9235 formed, named `.MMIX.sec.N'. Here, N is a number, a running count 9236 through the mmo file, starting at 0. 9237 9238 A loadable section specified as: 9239 9240 .section secname,"ax" 9241 TETRA 1,2,3,4,-1,-2009 9242 BYTE 80 9243 9244 and linked to address `0x4', is represented by the sequence: 9245 9246 0x98080050 - lop_spec 80 9247 0x00000002 - two 32-bit words for the section name 9248 0x7365636e - "secn" 9249 0x616d6500 - "ame\0" 9250 0x00000033 - flags CODE, READONLY, LOAD, ALLOC 9251 0x00000000 - high 32 bits of section length 9252 0x0000001c - section length is 28 bytes; 6 * 4 + 1 + alignment to 32 bits 9253 0x00000000 - high 32 bits of section address 9254 0x00000004 - section address is 4 9255 0x98010002 - 64 bits with address of following data 9256 0x00000000 - high 32 bits of address 9257 0x00000004 - low 32 bits: data starts at address 4 9258 0x00000001 - 1 9259 0x00000002 - 2 9260 0x00000003 - 3 9261 0x00000004 - 4 9262 0xffffffff - -1 9263 0xfffff827 - -2009 9264 0x50000000 - 80 as a byte, padded with zeros. 9265 9266 Note that the lop_spec wrapping does not include the section 9267 contents. Compare this to a non-loaded section specified as: 9268 9269 .section thirdsec 9270 TETRA 200001,100002 9271 BYTE 38,40 9272 9273 This, when linked to address `0x200000000000001c', is represented by: 9274 9275 0x98080050 - lop_spec 80 9276 0x00000002 - two 32-bit words for the section name 9277 0x7365636e - "thir" 9278 0x616d6500 - "dsec" 9279 0x00000010 - flag READONLY 9280 0x00000000 - high 32 bits of section length 9281 0x0000000c - section length is 12 bytes; 2 * 4 + 2 + alignment to 32 bits 9282 0x20000000 - high 32 bits of address 9283 0x0000001c - low 32 bits of address 0x200000000000001c 9284 0x00030d41 - 200001 9285 0x000186a2 - 100002 9286 0x26280000 - 38, 40 as bytes, padded with zeros 9287 9288 For the latter example, the section contents must not be loaded in 9289 memory, and is therefore specified as part of the special data. The 9290 address is usually unimportant but might provide information for e.g. 9291 the DWARF 2 debugging format. 9292 9293 9294 File: bfd.info, Node: GNU Free Documentation License, Next: BFD Index, Prev: BFD back ends, Up: Top 9295 9296 Version 1.3, 3 November 2008 9297 9298 Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc. 9299 `http://fsf.org/' 9300 9301 Everyone is permitted to copy and distribute verbatim copies 9302 of this license document, but changing it is not allowed. 9303 9304 0. PREAMBLE 9305 9306 The purpose of this License is to make a manual, textbook, or other 9307 functional and useful document "free" in the sense of freedom: to 9308 assure everyone the effective freedom to copy and redistribute it, 9309 with or without modifying it, either commercially or 9310 noncommercially. Secondarily, this License preserves for the 9311 author and publisher a way to get credit for their work, while not 9312 being considered responsible for modifications made by others. 9313 9314 This License is a kind of "copyleft", which means that derivative 9315 works of the document must themselves be free in the same sense. 9316 It complements the GNU General Public License, which is a copyleft 9317 license designed for free software. 9318 9319 We have designed this License in order to use it for manuals for 9320 free software, because free software needs free documentation: a 9321 free program should come with manuals providing the same freedoms 9322 that the software does. But this License is not limited to 9323 software manuals; it can be used for any textual work, regardless 9324 of subject matter or whether it is published as a printed book. 9325 We recommend this License principally for works whose purpose is 9326 instruction or reference. 9327 9328 1. APPLICABILITY AND DEFINITIONS 9329 9330 This License applies to any manual or other work, in any medium, 9331 that contains a notice placed by the copyright holder saying it 9332 can be distributed under the terms of this License. Such a notice 9333 grants a world-wide, royalty-free license, unlimited in duration, 9334 to use that work under the conditions stated herein. The 9335 "Document", below, refers to any such manual or work. Any member 9336 of the public is a licensee, and is addressed as "you". You 9337 accept the license if you copy, modify or distribute the work in a 9338 way requiring permission under copyright law. 9339 9340 A "Modified Version" of the Document means any work containing the 9341 Document or a portion of it, either copied verbatim, or with 9342 modifications and/or translated into another language. 9343 9344 A "Secondary Section" is a named appendix or a front-matter section 9345 of the Document that deals exclusively with the relationship of the 9346 publishers or authors of the Document to the Document's overall 9347 subject (or to related matters) and contains nothing that could 9348 fall directly within that overall subject. (Thus, if the Document 9349 is in part a textbook of mathematics, a Secondary Section may not 9350 explain any mathematics.) The relationship could be a matter of 9351 historical connection with the subject or with related matters, or 9352 of legal, commercial, philosophical, ethical or political position 9353 regarding them. 9354 9355 The "Invariant Sections" are certain Secondary Sections whose 9356 titles are designated, as being those of Invariant Sections, in 9357 the notice that says that the Document is released under this 9358 License. If a section does not fit the above definition of 9359 Secondary then it is not allowed to be designated as Invariant. 9360 The Document may contain zero Invariant Sections. If the Document 9361 does not identify any Invariant Sections then there are none. 9362 9363 The "Cover Texts" are certain short passages of text that are 9364 listed, as Front-Cover Texts or Back-Cover Texts, in the notice 9365 that says that the Document is released under this License. A 9366 Front-Cover Text may be at most 5 words, and a Back-Cover Text may 9367 be at most 25 words. 9368 9369 A "Transparent" copy of the Document means a machine-readable copy, 9370 represented in a format whose specification is available to the 9371 general public, that is suitable for revising the document 9372 straightforwardly with generic text editors or (for images 9373 composed of pixels) generic paint programs or (for drawings) some 9374 widely available drawing editor, and that is suitable for input to 9375 text formatters or for automatic translation to a variety of 9376 formats suitable for input to text formatters. A copy made in an 9377 otherwise Transparent file format whose markup, or absence of 9378 markup, has been arranged to thwart or discourage subsequent 9379 modification by readers is not Transparent. An image format is 9380 not Transparent if used for any substantial amount of text. A 9381 copy that is not "Transparent" is called "Opaque". 9382 9383 Examples of suitable formats for Transparent copies include plain 9384 ASCII without markup, Texinfo input format, LaTeX input format, 9385 SGML or XML using a publicly available DTD, and 9386 standard-conforming simple HTML, PostScript or PDF designed for 9387 human modification. Examples of transparent image formats include 9388 PNG, XCF and JPG. Opaque formats include proprietary formats that 9389 can be read and edited only by proprietary word processors, SGML or 9390 XML for which the DTD and/or processing tools are not generally 9391 available, and the machine-generated HTML, PostScript or PDF 9392 produced by some word processors for output purposes only. 9393 9394 The "Title Page" means, for a printed book, the title page itself, 9395 plus such following pages as are needed to hold, legibly, the 9396 material this License requires to appear in the title page. For 9397 works in formats which do not have any title page as such, "Title 9398 Page" means the text near the most prominent appearance of the 9399 work's title, preceding the beginning of the body of the text. 9400 9401 The "publisher" means any person or entity that distributes copies 9402 of the Document to the public. 9403 9404 A section "Entitled XYZ" means a named subunit of the Document 9405 whose title either is precisely XYZ or contains XYZ in parentheses 9406 following text that translates XYZ in another language. (Here XYZ 9407 stands for a specific section name mentioned below, such as 9408 "Acknowledgements", "Dedications", "Endorsements", or "History".) 9409 To "Preserve the Title" of such a section when you modify the 9410 Document means that it remains a section "Entitled XYZ" according 9411 to this definition. 9412 9413 The Document may include Warranty Disclaimers next to the notice 9414 which states that this License applies to the Document. These 9415 Warranty Disclaimers are considered to be included by reference in 9416 this License, but only as regards disclaiming warranties: any other 9417 implication that these Warranty Disclaimers may have is void and 9418 has no effect on the meaning of this License. 9419 9420 2. VERBATIM COPYING 9421 9422 You may copy and distribute the Document in any medium, either 9423 commercially or noncommercially, provided that this License, the 9424 copyright notices, and the license notice saying this License 9425 applies to the Document are reproduced in all copies, and that you 9426 add no other conditions whatsoever to those of this License. You 9427 may not use technical measures to obstruct or control the reading 9428 or further copying of the copies you make or distribute. However, 9429 you may accept compensation in exchange for copies. If you 9430 distribute a large enough number of copies you must also follow 9431 the conditions in section 3. 9432 9433 You may also lend copies, under the same conditions stated above, 9434 and you may publicly display copies. 9435 9436 3. COPYING IN QUANTITY 9437 9438 If you publish printed copies (or copies in media that commonly 9439 have printed covers) of the Document, numbering more than 100, and 9440 the Document's license notice requires Cover Texts, you must 9441 enclose the copies in covers that carry, clearly and legibly, all 9442 these Cover Texts: Front-Cover Texts on the front cover, and 9443 Back-Cover Texts on the back cover. Both covers must also clearly 9444 and legibly identify you as the publisher of these copies. The 9445 front cover must present the full title with all words of the 9446 title equally prominent and visible. You may add other material 9447 on the covers in addition. Copying with changes limited to the 9448 covers, as long as they preserve the title of the Document and 9449 satisfy these conditions, can be treated as verbatim copying in 9450 other respects. 9451 9452 If the required texts for either cover are too voluminous to fit 9453 legibly, you should put the first ones listed (as many as fit 9454 reasonably) on the actual cover, and continue the rest onto 9455 adjacent pages. 9456 9457 If you publish or distribute Opaque copies of the Document 9458 numbering more than 100, you must either include a 9459 machine-readable Transparent copy along with each Opaque copy, or 9460 state in or with each Opaque copy a computer-network location from 9461 which the general network-using public has access to download 9462 using public-standard network protocols a complete Transparent 9463 copy of the Document, free of added material. If you use the 9464 latter option, you must take reasonably prudent steps, when you 9465 begin distribution of Opaque copies in quantity, to ensure that 9466 this Transparent copy will remain thus accessible at the stated 9467 location until at least one year after the last time you 9468 distribute an Opaque copy (directly or through your agents or 9469 retailers) of that edition to the public. 9470 9471 It is requested, but not required, that you contact the authors of 9472 the Document well before redistributing any large number of 9473 copies, to give them a chance to provide you with an updated 9474 version of the Document. 9475 9476 4. MODIFICATIONS 9477 9478 You may copy and distribute a Modified Version of the Document 9479 under the conditions of sections 2 and 3 above, provided that you 9480 release the Modified Version under precisely this License, with 9481 the Modified Version filling the role of the Document, thus 9482 licensing distribution and modification of the Modified Version to 9483 whoever possesses a copy of it. In addition, you must do these 9484 things in the Modified Version: 9485 9486 A. Use in the Title Page (and on the covers, if any) a title 9487 distinct from that of the Document, and from those of 9488 previous versions (which should, if there were any, be listed 9489 in the History section of the Document). You may use the 9490 same title as a previous version if the original publisher of 9491 that version gives permission. 9492 9493 B. List on the Title Page, as authors, one or more persons or 9494 entities responsible for authorship of the modifications in 9495 the Modified Version, together with at least five of the 9496 principal authors of the Document (all of its principal 9497 authors, if it has fewer than five), unless they release you 9498 from this requirement. 9499 9500 C. State on the Title page the name of the publisher of the 9501 Modified Version, as the publisher. 9502 9503 D. Preserve all the copyright notices of the Document. 9504 9505 E. Add an appropriate copyright notice for your modifications 9506 adjacent to the other copyright notices. 9507 9508 F. Include, immediately after the copyright notices, a license 9509 notice giving the public permission to use the Modified 9510 Version under the terms of this License, in the form shown in 9511 the Addendum below. 9512 9513 G. Preserve in that license notice the full lists of Invariant 9514 Sections and required Cover Texts given in the Document's 9515 license notice. 9516 9517 H. Include an unaltered copy of this License. 9518 9519 I. Preserve the section Entitled "History", Preserve its Title, 9520 and add to it an item stating at least the title, year, new 9521 authors, and publisher of the Modified Version as given on 9522 the Title Page. If there is no section Entitled "History" in 9523 the Document, create one stating the title, year, authors, 9524 and publisher of the Document as given on its Title Page, 9525 then add an item describing the Modified Version as stated in 9526 the previous sentence. 9527 9528 J. Preserve the network location, if any, given in the Document 9529 for public access to a Transparent copy of the Document, and 9530 likewise the network locations given in the Document for 9531 previous versions it was based on. These may be placed in 9532 the "History" section. You may omit a network location for a 9533 work that was published at least four years before the 9534 Document itself, or if the original publisher of the version 9535 it refers to gives permission. 9536 9537 K. For any section Entitled "Acknowledgements" or "Dedications", 9538 Preserve the Title of the section, and preserve in the 9539 section all the substance and tone of each of the contributor 9540 acknowledgements and/or dedications given therein. 9541 9542 L. Preserve all the Invariant Sections of the Document, 9543 unaltered in their text and in their titles. Section numbers 9544 or the equivalent are not considered part of the section 9545 titles. 9546 9547 M. Delete any section Entitled "Endorsements". Such a section 9548 may not be included in the Modified Version. 9549 9550 N. Do not retitle any existing section to be Entitled 9551 "Endorsements" or to conflict in title with any Invariant 9552 Section. 9553 9554 O. Preserve any Warranty Disclaimers. 9555 9556 If the Modified Version includes new front-matter sections or 9557 appendices that qualify as Secondary Sections and contain no 9558 material copied from the Document, you may at your option 9559 designate some or all of these sections as invariant. To do this, 9560 add their titles to the list of Invariant Sections in the Modified 9561 Version's license notice. These titles must be distinct from any 9562 other section titles. 9563 9564 You may add a section Entitled "Endorsements", provided it contains 9565 nothing but endorsements of your Modified Version by various 9566 parties--for example, statements of peer review or that the text 9567 has been approved by an organization as the authoritative 9568 definition of a standard. 9569 9570 You may add a passage of up to five words as a Front-Cover Text, 9571 and a passage of up to 25 words as a Back-Cover Text, to the end 9572 of the list of Cover Texts in the Modified Version. Only one 9573 passage of Front-Cover Text and one of Back-Cover Text may be 9574 added by (or through arrangements made by) any one entity. If the 9575 Document already includes a cover text for the same cover, 9576 previously added by you or by arrangement made by the same entity 9577 you are acting on behalf of, you may not add another; but you may 9578 replace the old one, on explicit permission from the previous 9579 publisher that added the old one. 9580 9581 The author(s) and publisher(s) of the Document do not by this 9582 License give permission to use their names for publicity for or to 9583 assert or imply endorsement of any Modified Version. 9584 9585 5. COMBINING DOCUMENTS 9586 9587 You may combine the Document with other documents released under 9588 this License, under the terms defined in section 4 above for 9589 modified versions, provided that you include in the combination 9590 all of the Invariant Sections of all of the original documents, 9591 unmodified, and list them all as Invariant Sections of your 9592 combined work in its license notice, and that you preserve all 9593 their Warranty Disclaimers. 9594 9595 The combined work need only contain one copy of this License, and 9596 multiple identical Invariant Sections may be replaced with a single 9597 copy. If there are multiple Invariant Sections with the same name 9598 but different contents, make the title of each such section unique 9599 by adding at the end of it, in parentheses, the name of the 9600 original author or publisher of that section if known, or else a 9601 unique number. Make the same adjustment to the section titles in 9602 the list of Invariant Sections in the license notice of the 9603 combined work. 9604 9605 In the combination, you must combine any sections Entitled 9606 "History" in the various original documents, forming one section 9607 Entitled "History"; likewise combine any sections Entitled 9608 "Acknowledgements", and any sections Entitled "Dedications". You 9609 must delete all sections Entitled "Endorsements." 9610 9611 6. COLLECTIONS OF DOCUMENTS 9612 9613 You may make a collection consisting of the Document and other 9614 documents released under this License, and replace the individual 9615 copies of this License in the various documents with a single copy 9616 that is included in the collection, provided that you follow the 9617 rules of this License for verbatim copying of each of the 9618 documents in all other respects. 9619 9620 You may extract a single document from such a collection, and 9621 distribute it individually under this License, provided you insert 9622 a copy of this License into the extracted document, and follow 9623 this License in all other respects regarding verbatim copying of 9624 that document. 9625 9626 7. AGGREGATION WITH INDEPENDENT WORKS 9627 9628 A compilation of the Document or its derivatives with other 9629 separate and independent documents or works, in or on a volume of 9630 a storage or distribution medium, is called an "aggregate" if the 9631 copyright resulting from the compilation is not used to limit the 9632 legal rights of the compilation's users beyond what the individual 9633 works permit. When the Document is included in an aggregate, this 9634 License does not apply to the other works in the aggregate which 9635 are not themselves derivative works of the Document. 9636 9637 If the Cover Text requirement of section 3 is applicable to these 9638 copies of the Document, then if the Document is less than one half 9639 of the entire aggregate, the Document's Cover Texts may be placed 9640 on covers that bracket the Document within the aggregate, or the 9641 electronic equivalent of covers if the Document is in electronic 9642 form. Otherwise they must appear on printed covers that bracket 9643 the whole aggregate. 9644 9645 8. TRANSLATION 9646 9647 Translation is considered a kind of modification, so you may 9648 distribute translations of the Document under the terms of section 9649 4. Replacing Invariant Sections with translations requires special 9650 permission from their copyright holders, but you may include 9651 translations of some or all Invariant Sections in addition to the 9652 original versions of these Invariant Sections. You may include a 9653 translation of this License, and all the license notices in the 9654 Document, and any Warranty Disclaimers, provided that you also 9655 include the original English version of this License and the 9656 original versions of those notices and disclaimers. In case of a 9657 disagreement between the translation and the original version of 9658 this License or a notice or disclaimer, the original version will 9659 prevail. 9660 9661 If a section in the Document is Entitled "Acknowledgements", 9662 "Dedications", or "History", the requirement (section 4) to 9663 Preserve its Title (section 1) will typically require changing the 9664 actual title. 9665 9666 9. TERMINATION 9667 9668 You may not copy, modify, sublicense, or distribute the Document 9669 except as expressly provided under this License. Any attempt 9670 otherwise to copy, modify, sublicense, or distribute it is void, 9671 and will automatically terminate your rights under this License. 9672 9673 However, if you cease all violation of this License, then your 9674 license from a particular copyright holder is reinstated (a) 9675 provisionally, unless and until the copyright holder explicitly 9676 and finally terminates your license, and (b) permanently, if the 9677 copyright holder fails to notify you of the violation by some 9678 reasonable means prior to 60 days after the cessation. 9679 9680 Moreover, your license from a particular copyright holder is 9681 reinstated permanently if the copyright holder notifies you of the 9682 violation by some reasonable means, this is the first time you have 9683 received notice of violation of this License (for any work) from 9684 that copyright holder, and you cure the violation prior to 30 days 9685 after your receipt of the notice. 9686 9687 Termination of your rights under this section does not terminate 9688 the licenses of parties who have received copies or rights from 9689 you under this License. If your rights have been terminated and 9690 not permanently reinstated, receipt of a copy of some or all of 9691 the same material does not give you any rights to use it. 9692 9693 10. FUTURE REVISIONS OF THIS LICENSE 9694 9695 The Free Software Foundation may publish new, revised versions of 9696 the GNU Free Documentation License from time to time. Such new 9697 versions will be similar in spirit to the present version, but may 9698 differ in detail to address new problems or concerns. See 9699 `http://www.gnu.org/copyleft/'. 9700 9701 Each version of the License is given a distinguishing version 9702 number. If the Document specifies that a particular numbered 9703 version of this License "or any later version" applies to it, you 9704 have the option of following the terms and conditions either of 9705 that specified version or of any later version that has been 9706 published (not as a draft) by the Free Software Foundation. If 9707 the Document does not specify a version number of this License, 9708 you may choose any version ever published (not as a draft) by the 9709 Free Software Foundation. If the Document specifies that a proxy 9710 can decide which future versions of this License can be used, that 9711 proxy's public statement of acceptance of a version permanently 9712 authorizes you to choose that version for the Document. 9713 9714 11. RELICENSING 9715 9716 "Massive Multiauthor Collaboration Site" (or "MMC Site") means any 9717 World Wide Web server that publishes copyrightable works and also 9718 provides prominent facilities for anybody to edit those works. A 9719 public wiki that anybody can edit is an example of such a server. 9720 A "Massive Multiauthor Collaboration" (or "MMC") contained in the 9721 site means any set of copyrightable works thus published on the MMC 9722 site. 9723 9724 "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 9725 license published by Creative Commons Corporation, a not-for-profit 9726 corporation with a principal place of business in San Francisco, 9727 California, as well as future copyleft versions of that license 9728 published by that same organization. 9729 9730 "Incorporate" means to publish or republish a Document, in whole or 9731 in part, as part of another Document. 9732 9733 An MMC is "eligible for relicensing" if it is licensed under this 9734 License, and if all works that were first published under this 9735 License somewhere other than this MMC, and subsequently 9736 incorporated in whole or in part into the MMC, (1) had no cover 9737 texts or invariant sections, and (2) were thus incorporated prior 9738 to November 1, 2008. 9739 9740 The operator of an MMC Site may republish an MMC contained in the 9741 site under CC-BY-SA on the same site at any time before August 1, 9742 2009, provided the MMC is eligible for relicensing. 9743 9744 9745 ADDENDUM: How to use this License for your documents 9746 ==================================================== 9747 9748 To use this License in a document you have written, include a copy of 9749 the License in the document and put the following copyright and license 9750 notices just after the title page: 9751 9752 Copyright (C) YEAR YOUR NAME. 9753 Permission is granted to copy, distribute and/or modify this document 9754 under the terms of the GNU Free Documentation License, Version 1.3 9755 or any later version published by the Free Software Foundation; 9756 with no Invariant Sections, no Front-Cover Texts, and no Back-Cover 9757 Texts. A copy of the license is included in the section entitled ``GNU 9758 Free Documentation License''. 9759 9760 If you have Invariant Sections, Front-Cover Texts and Back-Cover 9761 Texts, replace the "with...Texts." line with this: 9762 9763 with the Invariant Sections being LIST THEIR TITLES, with 9764 the Front-Cover Texts being LIST, and with the Back-Cover Texts 9765 being LIST. 9766 9767 If you have Invariant Sections without Cover Texts, or some other 9768 combination of the three, merge those two alternatives to suit the 9769 situation. 9770 9771 If your document contains nontrivial examples of program code, we 9772 recommend releasing these examples in parallel under your choice of 9773 free software license, such as the GNU General Public License, to 9774 permit their use in free software. 9775 9776 9777 File: bfd.info, Node: BFD Index, Prev: GNU Free Documentation License, Up: Top 9778 9779 BFD Index 9780 ********* 9781 9782 [index] 9783 * Menu: 9784 9785 * _bfd_final_link_relocate: Relocating the section contents. 9786 (line 22) 9787 * _bfd_generic_link_add_archive_symbols: Adding symbols from an archive. 9788 (line 12) 9789 * _bfd_generic_link_add_one_symbol: Adding symbols from an object file. 9790 (line 19) 9791 * _bfd_generic_make_empty_symbol: symbol handling functions. 9792 (line 92) 9793 * _bfd_link_add_symbols in target vector: Adding Symbols to the Hash Table. 9794 (line 6) 9795 * _bfd_link_final_link in target vector: Performing the Final Link. 9796 (line 6) 9797 * _bfd_link_hash_table_create in target vector: Creating a Linker Hash Table. 9798 (line 6) 9799 * _bfd_relocate_contents: Relocating the section contents. 9800 (line 22) 9801 * aout_SIZE_machine_type: aout.
