A new object 51 file format can be supported simply by creating a new BFD back end and 52 adding it to the library. 53 54 BFD is split into two parts: the front end, and the back ends (one 55 for each object file format). 56 * The front end of BFD provides the interface to the user. It manages 57 memory and various canonical data structures. The front end also 58 decides which back end to use and when to call back end routines. 59 60 * The back ends provide BFD its view of the real world. Each back 61 end provides a set of calls which the BFD front end can use to 62 maintain its canonical form. The back ends also may keep around 63 information for their own use, for greater efficiency. 64 65 * Menu: 66 67 * History:: History 68 * How It Works:: How It Works 69 * What BFD Version 2 Can Do:: What BFD Version 2 Can Do 70 71 72 File: bfd.info, Node: History, Next: How It Works, Prev: Overview, Up: Overview 73 74 1.1 History 75 =========== 76 77 One spur behind BFD was the desire, on the part of the GNU 960 team at 78 Intel Oregon, for interoperability of applications on their COFF and 79 b.out file formats. Cygnus was providing GNU support for the team, and 80 was contracted to provide the required functionality. 81 82 The name came from a conversation David Wallace was having with 83 Richard Stallman about the library: RMS said that it would be quite 84 hard--David said "BFD". Stallman was right, but the name stuck. 85 86 At the same time, Ready Systems wanted much the same thing, but for 87 different object file formats: IEEE-695, Oasys, Srecords, a.out and 68k 88 coff. 89 90 BFD was first implemented by members of Cygnus Support; Steve 91 Chamberlain (`sac (a] cygnus.com'), John Gilmore (`gnu (a] cygnus.com'), K. 92 Richard Pixley (`rich (a] cygnus.com') and David Henkel-Wallace 93 (`gumby (a] cygnus.com'). 94 95 96 File: bfd.info, Node: How It Works, Next: What BFD Version 2 Can Do, Prev: History, Up: Overview 97 98 1.2 How To Use BFD 99 ================== 100 101 To use the library, include `bfd.h' and link with `libbfd.a'. 102 103 BFD provides a common interface to the parts of an object file for a 104 calling application. 105 106 When an application successfully opens a target file (object, 107 archive, or whatever), a pointer to an internal structure is returned. 108 This pointer points to a structure called `bfd', described in `bfd.h'. 109 Our convention is to call this pointer a BFD, and instances of it 110 within code `abfd'. All operations on the target object file are 111 applied as methods to the BFD. The mapping is defined within `bfd.h' 112 in a set of macros, all beginning with `bfd_' to reduce namespace 113 pollution. 114 115 For example, this sequence does what you would probably expect: 116 return the number of sections in an object file attached to a BFD 117 `abfd'. 118 119 #include "bfd.h" 120 121 unsigned int number_of_sections (abfd) 122 bfd *abfd; 123 { 124 return bfd_count_sections (abfd); 125 } 126 127 The abstraction used within BFD is that an object file has: 128 129 * a header, 130 131 * a number of sections containing raw data (*note Sections::), 132 133 * a set of relocations (*note Relocations::), and 134 135 * some symbol information (*note Symbols::). 136 Also, BFDs opened for archives have the additional attribute of an 137 index and contain subordinate BFDs. This approach is fine for a.out and 138 coff, but loses efficiency when applied to formats such as S-records and 139 IEEE-695. 140 141 142 File: bfd.info, Node: What BFD Version 2 Can Do, Prev: How It Works, Up: Overview 143 144 1.3 What BFD Version 2 Can Do 145 ============================= 146 147 When an object file is opened, BFD subroutines automatically determine 148 the format of the input object file. They then build a descriptor in 149 memory with pointers to routines that will be used to access elements of 150 the object file's data structures. 151 152 As different information from the object files is required, BFD 153 reads from different sections of the file and processes them. For 154 example, a very common operation for the linker is processing symbol 155 tables. Each BFD back end provides a routine for converting between 156 the object file's representation of symbols and an internal canonical 157 format. When the linker asks for the symbol table of an object file, it 158 calls through a memory pointer to the routine from the relevant BFD 159 back end which reads and converts the table into a canonical form. The 160 linker then operates upon the canonical form. When the link is finished 161 and the linker writes the output file's symbol table, another BFD back 162 end routine is called to take the newly created symbol table and 163 convert it into the chosen output format. 164 165 * Menu: 166 167 * BFD information loss:: Information Loss 168 * Canonical format:: The BFD canonical object-file format 169 170 171 File: bfd.info, Node: BFD information loss, Next: Canonical format, Up: What BFD Version 2 Can Do 172 173 1.3.1 Information Loss 174 ---------------------- 175 176 _Information can be lost during output._ The output formats supported 177 by BFD do not provide identical facilities, and information which can 178 be described in one form has nowhere to go in another format. One 179 example of this is alignment information in `b.out'. There is nowhere 180 in an `a.out' format file to store alignment information on the 181 contained data, so when a file is linked from `b.out' and an `a.out' 182 image is produced, alignment information will not propagate to the 183 output file. (The linker will still use the alignment information 184 internally, so the link is performed correctly). 185 186 Another example is COFF section names. COFF files may contain an 187 unlimited number of sections, each one with a textual section name. If 188 the target of the link is a format which does not have many sections 189 (e.g., `a.out') or has sections without names (e.g., the Oasys format), 190 the link cannot be done simply. You can circumvent this problem by 191 describing the desired input-to-output section mapping with the linker 192 command language. 193 194 _Information can be lost during canonicalization._ The BFD internal 195 canonical form of the external formats is not exhaustive; there are 196 structures in input formats for which there is no direct representation 197 internally. This means that the BFD back ends cannot maintain all 198 possible data richness through the transformation between external to 199 internal and back to external formats. 200 201 This limitation is only a problem when an application reads one 202 format and writes another. Each BFD back end is responsible for 203 maintaining as much data as possible, and the internal BFD canonical 204 form has structures which are opaque to the BFD core, and exported only 205 to the back ends. When a file is read in one format, the canonical form 206 is generated for BFD and the application. At the same time, the back 207 end saves away any information which may otherwise be lost. If the data 208 is then written back in the same format, the back end routine will be 209 able to use the canonical form provided by the BFD core as well as the 210 information it prepared earlier. Since there is a great deal of 211 commonality between back ends, there is no information lost when 212 linking or copying big endian COFF to little endian COFF, or `a.out' to 213 `b.out'. When a mixture of formats is linked, the information is only 214 lost from the files whose format differs from the destination. 215 216 217 File: bfd.info, Node: Canonical format, Prev: BFD information loss, Up: What BFD Version 2 Can Do 218 219 1.3.2 The BFD canonical object-file format 220 ------------------------------------------ 221 222 The greatest potential for loss of information occurs when there is the 223 least overlap between the information provided by the source format, 224 that stored by the canonical format, and that needed by the destination 225 format. A brief description of the canonical form may help you 226 understand which kinds of data you can count on preserving across 227 conversions. 228 229 _files_ 230 Information stored on a per-file basis includes target machine 231 architecture, particular implementation format type, a demand 232 pageable bit, and a write protected bit. Information like Unix 233 magic numbers is not stored here--only the magic numbers' meaning, 234 so a `ZMAGIC' file would have both the demand pageable bit and the 235 write protected text bit set. The byte order of the target is 236 stored on a per-file basis, so that big- and little-endian object 237 files may be used with one another. 238 239 _sections_ 240 Each section in the input file contains the name of the section, 241 the section's original address in the object file, size and 242 alignment information, various flags, and pointers into other BFD 243 data structures. 244 245 _symbols_ 246 Each symbol contains a pointer to the information for the object 247 file which originally defined it, its name, its value, and various 248 flag bits. When a BFD back end reads in a symbol table, it 249 relocates all symbols to make them relative to the base of the 250 section where they were defined. Doing this ensures that each 251 symbol points to its containing section. Each symbol also has a 252 varying amount of hidden private data for the BFD back end. Since 253 the symbol points to the original file, the private data format 254 for that symbol is accessible. `ld' can operate on a collection 255 of symbols of wildly different formats without problems. 256 257 Normal global and simple local symbols are maintained on output, 258 so an output file (no matter its format) will retain symbols 259 pointing to functions and to global, static, and common variables. 260 Some symbol information is not worth retaining; in `a.out', type 261 information is stored in the symbol table as long symbol names. 262 This information would be useless to most COFF debuggers; the 263 linker has command line switches to allow users to throw it away. 264 265 There is one word of type information within the symbol, so if the 266 format supports symbol type information within symbols (for 267 example, COFF, IEEE, Oasys) and the type is simple enough to fit 268 within one word (nearly everything but aggregates), the 269 information will be preserved. 270 271 _relocation level_ 272 Each canonical BFD relocation record contains a pointer to the 273 symbol to relocate to, the offset of the data to relocate, the 274 section the data is in, and a pointer to a relocation type 275 descriptor. Relocation is performed by passing messages through 276 the relocation type descriptor and the symbol pointer. Therefore, 277 relocations can be performed on output data using a relocation 278 method that is only available in one of the input formats. For 279 instance, Oasys provides a byte relocation format. A relocation 280 record requesting this relocation type would point indirectly to a 281 routine to perform this, so the relocation may be performed on a 282 byte being written to a 68k COFF file, even though 68k COFF has no 283 such relocation type. 284 285 _line numbers_ 286 Object formats can contain, for debugging purposes, some form of 287 mapping between symbols, source line numbers, and addresses in the 288 output file. These addresses have to be relocated along with the 289 symbol information. Each symbol with an associated list of line 290 number records points to the first record of the list. The head 291 of a line number list consists of a pointer to the symbol, which 292 allows finding out the address of the function whose line number 293 is being described. The rest of the list is made up of pairs: 294 offsets into the section and line numbers. Any format which can 295 simply derive this information can pass it successfully between 296 formats (COFF, IEEE and Oasys). 297 298 299 File: bfd.info, Node: BFD front end, Next: BFD back ends, Prev: Overview, Up: Top 300 301 2 BFD Front End 302 *************** 303 304 2.1 `typedef bfd' 305 ================= 306 307 A BFD has type `bfd'; objects of this type are the cornerstone of any 308 application using BFD.

If MESSAGE is non-NULL and non-empty, the error 649 string printed is preceded by MESSAGE, a colon, and a space. It is 650 followed by a newline. 651 652 2.2.2 BFD error handler 653 ----------------------- 654 655 Some BFD functions want to print messages describing the problem. They 656 call a BFD error handler function. This function may be overridden by 657 the program. 658 659 The BFD error handler acts like printf. 660 661 662 typedef void (*bfd_error_handler_type) (const char *, ...); 663 664 2.2.2.1 `bfd_set_error_handler' 665 ............................... 666 667 *Synopsis* 668 bfd_error_handler_type bfd_set_error_handler (bfd_error_handler_type); 669 *Description* 670 Set the BFD error handler function.

E.g., an attempt 747 was made to set the `D_PAGED' bit on a BFD format which does not 748 support demand paging. 749 750 2.3.1.5 `bfd_get_arch_size' 751 ........................... 752 753 *Synopsis* 754 int bfd_get_arch_size (bfd *abfd); 755 *Description* 756 Returns the architecture address size, in bits, as determined by the 757 object file's format.

Some architectures implicitly sign extend address values when 771 they are converted to types larger than the size of an address. For 772 instance, bfd_get_start_address() will return an address sign extended 773 to fill a bfd_vma when this is the case. 774 775 *Returns* 776 Returns `1' if the target architecture is known to sign extend 777 addresses, `0' if the target architecture is known to not sign extend 778 addresses, and `-1' otherwise. 779 780 2.3.1.7 `bfd_set_start_address' 781 ............................... 782 783 *Synopsis* 784 bfd_boolean bfd_set_start_address (bfd *abfd, bfd_vma vma); 785 *Description* 786 Make VMA the entry point of output BFD ABFD. 787 788 *Returns* 789 Returns `TRUE' on success, `FALSE' otherwise. 790 791 2.3.1.8 `bfd_get_gp_size' 792 ......................... 793 794 *Synopsis* 795 unsigned int bfd_get_gp_size (bfd *abfd); 796 *Description* 797 Return the maximum size of objects to be optimized using the GP 798 register under MIPS ECOFF.

(Though without as many bells and 819 whistles as `strtoul'.) The expression is assumed to be unsigned 820 (i.e., positive). If given a BASE, it is used as the base for 821 conversion. A base of 0 causes the function to interpret the string in 822 hex if a leading "0x" or "0X" is found, otherwise in octal if a leading 823 zero is found, otherwise in decimal. 824 825 If the value would overflow, the maximum `bfd_vma' value is returned. 826 827 2.3.1.11 `bfd_copy_private_header_data' 828 ....................................... 829 830 *Synopsis* 831 bfd_boolean bfd_copy_private_header_data (bfd *ibfd, bfd *obfd); 832 *Description* 833 Copy private BFD header information from the BFD IBFD to the the BFD 834 OBFD.

It 1150 would be ideal if someone could eventually modify it so that such 1151 results were guaranteed. 1152 1153 Instead, we want to ask questions like "is this NNN byte sized 1154 object I'm about to try read from file offset YYY reasonable?" As as 1155 example of where we might do this, some object formats use string 1156 tables for which the first `sizeof (long)' bytes of the table contain 1157 the size of the table itself, including the size bytes. If an 1158 application tries to read what it thinks is one of these string tables, 1159 without some way to validate the size, and for some reason the size is 1160 wrong (byte swapping error, wrong location for the string table, etc.), 1161 the only clue is likely to be a read error when it tries to read the 1162 table, or a "virtual memory exhausted" error when it tries to allocate 1163 15 bazillon bytes of space for the 15 bazillon byte table it is about 1164 to read. This function at least allows us to answer the question, "is 1165 the size reasonable?". 1166 1167 2.3.1.28 `bfd_mmap' 1168 ................... 1169 1170 *Synopsis* 1171 void *bfd_mmap (bfd *abfd, void *addr, bfd_size_type len, 1172 int prot, int flags, file_ptr offset); 1173 *Description* 1174 Return mmap()ed region of the file, if possible and implemented. 1175 1176 * Menu: 1177 1178 * Memory Usage:: 1179 * Initialization:: 1180 * Sections:: 1181 * Symbols:: 1182 * Archives:: 1183 * Formats:: 1184 * Relocations:: 1185 * Core Files:: 1186 * Targets:: 1187 * Architectures:: 1188 * Opening and Closing:: 1189 * Internal:: 1190 * File Caching:: 1191 * Linker Functions:: 1192 * Hash Tables:: 1193 1194 1195 File: bfd.info, Node: Memory Usage, Next: Initialization, Prev: BFD front end, Up: BFD front end 1196 1197 2.4 Memory Usage 1198 ================ 1199 1200 BFD keeps all of its internal structures in obstacks. There is one 1201 obstack per open BFD file, into which the current state is stored. When 1202 a BFD is closed, the obstack is deleted, and so everything which has 1203 been allocated by BFD for the closing file is thrown away. 1204 1205 BFD does not free anything created by an application, but pointers 1206 into `bfd' structures become invalid on a `bfd_close'; for example, 1207 after a `bfd_close' the vector passed to `bfd_canonicalize_symtab' is 1208 still around, since it has been allocated by the application, but the 1209 data that it pointed to are lost. 1210 1211 The general rule is to not close a BFD until all operations dependent 1212 upon data from the BFD have been completed, or all the data from within 1213 the file has been copied. To help with the management of memory, there 1214 is a function (`bfd_alloc_size') which returns the number of bytes in 1215 obstacks associated with the supplied BFD. This could be used to select 1216 the greediest open BFD, close it to reclaim the memory, perform some 1217 operation and reopen the BFD again, to get a fresh copy of the data 1218 structures. 1219 1220 1221 File: bfd.info, Node: Initialization, Next: Sections, Prev: Memory Usage, Up: BFD front end 1222 1223 2.5 Initialization 1224 ================== 1225 1226 2.5.1 Initialization functions 1227 ------------------------------ 1228 1229 These are the functions that handle initializing a BFD. 1230 1231 2.5.1.1 `bfd_init' 1232 .................. 1233 1234 *Synopsis* 1235 void bfd_init (void); 1236 *Description* 1237 This routine must be called before any other BFD function to initialize 1238 magical internal data structures. 1239 1240 1241 File: bfd.info, Node: Sections, Next: Symbols, Prev: Initialization, Up: BFD front end 1242 1243 2.6 Sections 1244 ============ 1245 1246 The raw data contained within a BFD is maintained through the section 1247 abstraction. A single BFD may have any number of sections. It keeps 1248 hold of them by pointing to the first; each one points to the next in 1249 the list. 1250 1251 Sections are supported in BFD in `section.c'. 1252 1253 * Menu: 1254 1255 * Section Input:: 1256 * Section Output:: 1257 * typedef asection:: 1258 * section prototypes:: 1259 1260 1261 File: bfd.info, Node: Section Input, Next: Section Output, Prev: Sections, Up: Sections 1262 1263 2.6.1 Section input 1264 ------------------- 1265 1266 When a BFD is opened for reading, the section structures are created 1267 and attached to the BFD. 1268 1269 Each section has a name which describes the section in the outside 1270 world--for example, `a.out' would contain at least three sections, 1271 called `.text', `.data' and `.bss'. 1272 1273 Names need not be unique; for example a COFF file may have several 1274 sections named `.data'. 1275 1276 Sometimes a BFD will contain more than the "natural" number of 1277 sections. A back end may attach other sections containing constructor 1278 data, or an application may add a section (using `bfd_make_section') to 1279 the sections attached to an already open BFD. For example, the linker 1280 creates an extra section `COMMON' for each input file's BFD to hold 1281 information about common storage. 1282 1283 The raw data is not necessarily read in when the section descriptor 1284 is created. Some targets may leave the data in place until a 1285 `bfd_get_section_contents' call is made. Other back ends may read in 1286 all the data at once. For example, an S-record file has to be read 1287 once to determine the size of the data. An IEEE-695 file doesn't 1288 contain raw data in sections, but data and relocation expressions 1289 intermixed, so the data area has to be parsed to get out the data and 1290 relocations. 1291 1292 1293 File: bfd.info, Node: Section Output, Next: typedef asection, Prev: Section Input, Up: Sections 1294 1295 2.6.2 Section output 1296 -------------------- 1297 1298 To write a new object style BFD, the various sections to be written 1299 have to be created. They are attached to the BFD in the same way as 1300 input sections; data is written to the sections using 1301 `bfd_set_section_contents'. 1302 1303 Any program that creates or combines sections (e.g., the assembler 1304 and linker) must use the `asection' fields `output_section' and 1305 `output_offset' to indicate the file sections to which each section 1306 must be written. (If the section is being created from scratch, 1307 `output_section' should probably point to the section itself and 1308 `output_offset' should probably be zero.) 1309 1310 The data to be written comes from input sections attached (via 1311 `output_section' pointers) to the output sections. The output section 1312 structure can be considered a filter for the input section: the output 1313 section determines the vma of the output data and the name, but the 1314 input section determines the offset into the output section of the data 1315 to be written. 1316 1317 E.g., to create a section "O", starting at 0x100, 0x123 long, 1318 containing two subsections, "A" at offset 0x0 (i.e., at vma 0x100) and 1319 "B" at offset 0x20 (i.e., at vma 0x120) the `asection' structures would 1320 look like: 1321 1322 section name "A" 1323 output_offset 0x00 1324 size 0x20 1325 output_section -----------> section name "O" 1326 | vma 0x100 1327 section name "B" | size 0x123 1328 output_offset 0x20 | 1329 size 0x103 | 1330 output_section --------| 1331 1332 2.6.3 Link orders 1333 ----------------- 1334 1335 The data within a section is stored in a "link_order". These are much 1336 like the fixups in `gas'. The link_order abstraction allows a section 1337 to grow and shrink within itself. 1338 1339 A link_order knows how big it is, and which is the next link_order 1340 and where the raw data for it is; it also points to a list of 1341 relocations which apply to it. 1342 1343 The link_order is used by the linker to perform relaxing on final 1344 code. The compiler creates code which is as big as necessary to make 1345 it work without relaxing, and the user can select whether to relax. 1346 Sometimes relaxing takes a lot of time. The linker runs around the 1347 relocations to see if any are attached to data which can be shrunk, if 1348 so it does it on a link_order by link_order basis. 1349 1350 1351 File: bfd.info, Node: typedef asection, Next: section prototypes, Prev: Section Output, Up: Sections 1352 1353 2.6.4 typedef asection 1354 ---------------------- 1355 1356 Here is the section structure: 1357 1358 1359 typedef struct bfd_section 1360 { 1361 /* The name of the section; the name isn't a copy, the pointer is 1362 the same as that passed to bfd_make_section. */ 1363 const char *name; 1364 1365 /* A unique sequence number. */ 1366 int id; 1367 1368 /* Which section in the bfd; 0..n-1 as sections are created in a bfd. */ 1369 int index; 1370 1371 /* The next section in the list belonging to the BFD, or NULL. */ 1372 struct bfd_section *next; 1373 1374 /* The previous section in the list belonging to the BFD, or NULL. */ 1375 struct bfd_section *prev; 1376 1377 /* The field flags contains attributes of the section.

BFD passes information to 2193 applications though the `asymbol' structure. When the application 2194 requests the symbol table, BFD reads the table in the native form and 2195 translates parts of it into the internal format. To maintain more than 2196 the information passed to applications, some targets keep some 2197 information "behind the scenes" in a structure only the particular back 2198 end knows about. For example, the coff back end keeps the original 2199 symbol table structure as well as the canonical structure when a BFD is 2200 read in. On output, the coff back end can reconstruct the output symbol 2201 table so that no information is lost, even information unique to coff 2202 which BFD doesn't know or understand. If a coff symbol table were read, 2203 but were written through an a.out back end, all the coff specific 2204 information would be lost. The symbol table of a BFD is not necessarily 2205 read in until a canonicalize request is made. Then the BFD back end 2206 fills in a table provided by the application with pointers to the 2207 canonical information. To output symbols, the application provides BFD 2208 with a table of pointers to pointers to `asymbol's. This allows 2209 applications like the linker to output a symbol as it was read, since 2210 the "behind the scenes" information will be still available. 2211 2212 * Menu: 2213 2214 * Reading Symbols:: 2215 * Writing Symbols:: 2216 * Mini Symbols:: 2217 * typedef asymbol:: 2218 * symbol handling functions:: 2219 2220 2221 File: bfd.info, Node: Reading Symbols, Next: Writing Symbols, Prev: Symbols, Up: Symbols 2222 2223 2.7.1 Reading symbols 2224 --------------------- 2225 2226 There are two stages to reading a symbol table from a BFD: allocating 2227 storage, and the actual reading process. This is an excerpt from an 2228 application which reads the symbol table: 2229 2230 long storage_needed; 2231 asymbol **symbol_table; 2232 long number_of_symbols; 2233 long i; 2234 2235 storage_needed = bfd_get_symtab_upper_bound (abfd); 2236 2237 if (storage_needed < 0) 2238 FAIL 2239 2240 if (storage_needed == 0) 2241 return; 2242 2243 symbol_table = xmalloc (storage_needed); 2244 ... 2245 number_of_symbols = 2246 bfd_canonicalize_symtab (abfd, symbol_table); 2247 2248 if (number_of_symbols < 0) 2249 FAIL 2250 2251 for (i = 0; i < number_of_symbols; i++) 2252 process_symbol (symbol_table[i]); 2253 2254 All storage for the symbols themselves is in an objalloc connected 2255 to the BFD; it is freed when the BFD is closed. 2256 2257 2258 File: bfd.info, Node: Writing Symbols, Next: Mini Symbols, Prev: Reading Symbols, Up: Symbols 2259 2260 2.7.2 Writing symbols 2261 --------------------- 2262 2263 Writing of a symbol table is automatic when a BFD open for writing is 2264 closed. The application attaches a vector of pointers to pointers to 2265 symbols to the BFD being written, and fills in the symbol count. The 2266 close and cleanup code reads through the table provided and performs 2267 all the necessary operations. The BFD output code must always be 2268 provided with an "owned" symbol: one which has come from another BFD, 2269 or one which has been created using `bfd_make_empty_symbol'. Here is an 2270 example showing the creation of a symbol table with only one element: 2271 2272 #include "bfd.h" 2273 int main (void) 2274 { 2275 bfd *abfd; 2276 asymbol *ptrs[2]; 2277 asymbol *new; 2278 2279 abfd = bfd_openw ("foo","a.out-sunos-big"); 2280 bfd_set_format (abfd, bfd_object); 2281 new = bfd_make_empty_symbol (abfd); 2282 new->name = "dummy_symbol"; 2283 new->section = bfd_make_section_old_way (abfd, ".text"); 2284 new->flags = BSF_GLOBAL; 2285 new->value = 0x12345; 2286 2287 ptrs[0] = new; 2288 ptrs[1] = 0; 2289 2290 bfd_set_symtab (abfd, ptrs, 1); 2291 bfd_close (abfd); 2292 return 0; 2293 } 2294 2295 ./makesym 2296 nm foo 2297 00012345 A dummy_symbol 2298 2299 Many formats cannot represent arbitrary symbol information; for 2300 instance, the `a.out' object format does not allow an arbitrary number 2301 of sections. A symbol pointing to a section which is not one of 2302 `.text', `.data' or `.bss' cannot be described. 2303 2304 2305 File: bfd.info, Node: Mini Symbols, Next: typedef asymbol, Prev: Writing Symbols, Up: Symbols 2306 2307 2.7.3 Mini Symbols 2308 ------------------ 2309 2310 Mini symbols provide read-only access to the symbol table. They use 2311 less memory space, but require more time to access. They can be useful 2312 for tools like nm or objdump, which may have to handle symbol tables of 2313 extremely large executables. 2314 2315 The `bfd_read_minisymbols' function will read the symbols into 2316 memory in an internal form.

It has a symbol table, 2645 although there's not much a user program will do with it. 2646 2647 The big difference between an archive BFD and an ordinary BFD is 2648 that the archive doesn't have sections. Instead it has a chain of BFDs 2649 that are considered its contents. These BFDs can be manipulated like 2650 any other. The BFDs contained in an archive opened for reading will 2651 all be opened for reading. You may put either input or output BFDs 2652 into an archive opened for output; they will be handled correctly when 2653 the archive is closed. 2654 2655 Use `bfd_openr_next_archived_file' to step through the contents of 2656 an archive opened for input. You don't have to read the entire archive 2657 if you don't want to! Read it until you find what you want. 2658 2659 Archive contents of output BFDs are chained through the `next' 2660 pointer in a BFD. The first one is findable through the `archive_head' 2661 slot of the archive. Set it with `bfd_set_archive_head' (q.v.). A 2662 given BFD may be in only one open output archive at a time. 2663 2664 As expected, the BFD archive code is more general than the archive 2665 code of any given environment. BFD archives may contain files of 2666 different formats (e.g., a.out and coff) and even different 2667 architectures. You may even place archives recursively into archives! 2668 2669 This can cause unexpected confusion, since some archive formats are 2670 more expressive than others. For instance, Intel COFF archives can 2671 preserve long filenames; SunOS a.out archives cannot. If you move a 2672 file from the first to the second format and back again, the filename 2673 may be truncated. Likewise, different a.out environments have different 2674 conventions as to how they truncate filenames, whether they preserve 2675 directory names in filenames, etc. When interoperating with native 2676 tools, be sure your files are homogeneous. 2677 2678 Beware: most of these formats do not react well to the presence of 2679 spaces in filenames. We do the best we can, but can't always handle 2680 this case due to restrictions in the format of archives. Many Unix 2681 utilities are braindead in regards to spaces and such in filenames 2682 anyway, so this shouldn't be much of a restriction. 2683 2684 Archives are supported in BFD in `archive.c'. 2685 2686 2.8.1 Archive functions 2687 ----------------------- 2688 2689 2.8.1.1 `bfd_get_next_mapent' 2690 ............................. 2691 2692 *Synopsis* 2693 symindex bfd_get_next_mapent 2694 (bfd *abfd, symindex previous, carsym **sym); 2695 *Description* 2696 Step through archive ABFD's symbol table (if it has one).

The symbol is referenced through a pointer to a pointer so 2903 that tools like the linker can fix up all the symbols of the same name 2904 by modifying only one pointer. The relocation routine looks in the 2905 symbol and uses the base of the section the symbol is attached to and 2906 the value of the symbol as the initial relocation offset. If the symbol 2907 pointer is zero, then the section provided is looked up. 2908 2909 * `address' 2910 The `address' field gives the offset in bytes from the base of the 2911 section data which owns the relocation record to the first byte of 2912 relocatable information. The actual data relocated will be relative to 2913 this point; for example, a relocation type which modifies the bottom 2914 two bytes of a four byte word would not touch the first byte pointed to 2915 in a big endian world. 2916 2917 * `addend' 2918 The `addend' is a value provided by the back end to be added (!) to 2919 the relocation offset. Its interpretation is dependent upon the howto. 2920 For example, on the 68k the code: 2921 2922 char foo[]; 2923 main() 2924 { 2925 return foo[0x12345678]; 2926 } 2927 2928 Could be compiled into: 2929 2930 linkw fp,#-4 2931 moveb @#12345678,d0 2932 extbl d0 2933 unlk fp 2934 rts 2935 2936 This could create a reloc pointing to `foo', but leave the offset in 2937 the data, something like: 2938 2939 RELOCATION RECORDS FOR [.text]: 2940 offset type value 2941 00000006 32 _foo 2942 2943 00000000 4e56 fffc ; linkw fp,#-4 2944 00000004 1039 1234 5678 ; moveb @#12345678,d0 2945 0000000a 49c0 ; extbl d0 2946 0000000c 4e5e ; unlk fp 2947 0000000e 4e75 ; rts 2948 2949 Using coff and an 88k, some instructions don't have enough space in 2950 them to represent the full address range, and pointers have to be 2951 loaded in two parts. So you'd get something like: 2952 2953 or.u r13,r0,hi16(_foo+0x12345678) 2954 ld.b r2,r13,lo16(_foo+0x12345678) 2955 jmp r1 2956 2957 This should create two relocs, both pointing to `_foo', and with 2958 0x12340000 in their addend field. The data would consist of: 2959 2960 RELOCATION RECORDS FOR [.text]: 2961 offset type value 2962 00000002 HVRT16 _foo+0x12340000 2963 00000006 LVRT16 _foo+0x12340000 2964 2965 00000000 5da05678 ; or.u r13,r0,0x5678 2966 00000004 1c4d5678 ; ld.b r2,r13,0x5678 2967 00000008 f400c001 ; jmp r1 2968 2969 The relocation routine digs out the value from the data, adds it to 2970 the addend to get the original offset, and then adds the value of 2971 `_foo'. Note that all 32 bits have to be kept around somewhere, to cope 2972 with carry from bit 15 to bit 16. 2973 2974 One further example is the sparc and the a.out format. The sparc has 2975 a similar problem to the 88k, in that some instructions don't have room 2976 for an entire offset, but on the sparc the parts are created in odd 2977 sized lumps. The designers of the a.out format chose to not use the 2978 data within the section for storing part of the offset; all the offset 2979 is kept within the reloc. Anything in the data should be ignored. 2980 2981 save %sp,-112,%sp 2982 sethi %hi(_foo+0x12345678),%g2 2983 ldsb [%g2+%lo(_foo+0x12345678)],%i0 2984 ret 2985 restore 2986 2987 Both relocs contain a pointer to `foo', and the offsets contain junk. 2988 2989 RELOCATION RECORDS FOR [.text]: 2990 offset type value 2991 00000004 HI22 _foo+0x12345678 2992 00000008 LO10 _foo+0x12345678 2993 2994 00000000 9de3bf90 ; save %sp,-112,%sp 2995 00000004 05000000 ; sethi %hi(_foo+0),%g2 2996 00000008 f048a000 ; ldsb [%g2+%lo(_foo+0)],%i0 2997 0000000c 81c7e008 ; ret 2998 00000010 81e80000 ; restore 2999 3000 * `howto' 3001 The `howto' field can be imagined as a relocation instruction. It is 3002 a pointer to a structure which contains information on what to do with 3003 all of the other information in the reloc record and data section. A 3004 back end would normally have a relocation instruction set and turn 3005 relocations into pointers to the correct structure on input - but it 3006 would be possible to create each howto field on demand. 3007 3008 2.10.1.1 `enum complain_overflow' 3009 ................................. 3010 3011 Indicates what sort of overflow checking should be done when performing 3012 a relocation. 3013 3014 3015 enum complain_overflow 3016 { 3017 /* Do not complain on overflow. */ 3018 complain_overflow_dont, 3019 3020 /* Complain if the value overflows when considered as a signed 3021 number one bit larger than the field. ie.

There are two 3220 ways of reflecting the results of partial linkage in an output file: by 3221 modifying the output data in place, and by modifying the relocation 3222 record. Some native formats (e.g., basic a.out and basic coff) have no 3223 way of specifying an addend in the relocation type, so the addend has 3224 to go in the output data. This is no big deal since in these formats 3225 the output data slot will always be big enough for the addend. Complex 3226 reloc types with addends were invented to solve just this problem.

Some of these treat the symbol or 3483 "addend" in some special way. For GPDISP_HI16 ("gpdisp") 3484 relocations, the symbol is ignored when writing; when reading, it 3485 will be the absolute section symbol. The addend is the 3486 displacement in bytes of the "lda" instruction from the "ldah" 3487 instruction (which is at the address of this reloc). 3488 3489 -- : BFD_RELOC_ALPHA_GPDISP_LO16 3490 For GPDISP_LO16 ("ignore") relocations, the symbol is handled as 3491 with GPDISP_HI16 relocs.

The addend is ignored when writing, but is filled 3510 in with the file's GP value on reading, for convenience, as with 3511 the GPDISP_LO16 reloc. 3512 3513 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and 3514 GPDISP_LO16.

All the back end provides to the root part of BFD is a 5682 structure containing pointers to functions which perform certain low 5683 level operations on files. BFD translates the applications's requests 5684 through a pointer into calls to the back end routines. 5685 5686 When a file is opened with `bfd_openr', its format and target are 5687 unknown. BFD uses various mechanisms to determine how to interpret the 5688 file. The operations performed are: 5689 5690 * Create a BFD by calling the internal routine `_bfd_new_bfd', then 5691 call `bfd_find_target' with the target string supplied to 5692 `bfd_openr' and the new BFD pointer. 5693 5694 * If a null target string was provided to `bfd_find_target', look up 5695 the environment variable `GNUTARGET' and use that as the target 5696 string. 5697 5698 * If the target string is still `NULL', or the target string is 5699 `default', then use the first item in the target vector as the 5700 target type, and set `target_defaulted' in the BFD to cause 5701 `bfd_check_format' to loop through all the targets. *Note 5702 bfd_target::. *Note Formats::. 5703 5704 * Otherwise, inspect the elements in the target vector one by one, 5705 until a match on target name is found. When found, use it. 5706 5707 * Otherwise return the error `bfd_error_invalid_target' to 5708 `bfd_openr'. 5709 5710 * `bfd_openr' attempts to open the file using `bfd_open_file', and 5711 returns the BFD. 5712 Once the BFD has been opened and the target selected, the file 5713 format may be determined. This is done by calling `bfd_check_format' on 5714 the BFD with a suggested format. If `target_defaulted' has been set, 5715 each possible target type is tried to see if it recognizes the 5716 specified format. `bfd_check_format' returns `TRUE' when the caller 5717 guesses right. 5718 5719 * Menu: 5720 5721 * bfd_target:: 5722 5723 5724 File: bfd.info, Node: bfd_target, Prev: Targets, Up: Targets 5725 5726 2.12.1 bfd_target 5727 ----------------- 5728 5729 *Description* 5730 This structure contains everything that BFD knows about a target. It 5731 includes things like its byte order, name, and which routines to call 5732 to do various operations. 5733 5734 Every BFD points to a target structure with its `xvec' member. 5735 5736 The macros below are used to dispatch to functions through the 5737 `bfd_target' vector. They are used in a number of macros further down 5738 in `bfd.h', and are also used when calling various routines by hand 5739 inside the BFD implementation. The ARGLIST argument must be 5740 parenthesized; it contains all the arguments to the called function. 5741 5742 They make the documentation (more) unpleasant to read, so if someone 5743 wants to fix this and not break the above, please do. 5744 #define BFD_SEND(bfd, message, arglist) \ 5745 ((*((bfd)->xvec->message)) arglist) 5746 5747 #ifdef DEBUG_BFD_SEND 5748 #undef BFD_SEND 5749 #define BFD_SEND(bfd, message, arglist) \ 5750 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \ 5751 ((*((bfd)->xvec->message)) arglist) : \ 5752 (bfd_assert (__FILE__,__LINE__), NULL)) 5753 #endif 5754 For operations which index on the BFD format: 5755 #define BFD_SEND_FMT(bfd, message, arglist) \ 5756 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) 5757 5758 #ifdef DEBUG_BFD_SEND 5759 #undef BFD_SEND_FMT 5760 #define BFD_SEND_FMT(bfd, message, arglist) \ 5761 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \ 5762 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \ 5763 (bfd_assert (__FILE__,__LINE__), NULL)) 5764 #endif 5765 This is the structure which defines the type of BFD this is. The 5766 `xvec' member of the struct `bfd' itself points here. Each module that 5767 implements access to a different target under BFD, defines one of these. 5768 5769 FIXME, these names should be rationalised with the names of the 5770 entry points which call them. Too bad we can't have one macro to define 5771 them both! 5772 enum bfd_flavour 5773 { 5774 bfd_target_unknown_flavour, 5775 bfd_target_aout_flavour, 5776 bfd_target_coff_flavour, 5777 bfd_target_ecoff_flavour, 5778 bfd_target_xcoff_flavour, 5779 bfd_target_elf_flavour, 5780 bfd_target_ieee_flavour, 5781 bfd_target_nlm_flavour, 5782 bfd_target_oasys_flavour, 5783 bfd_target_tekhex_flavour, 5784 bfd_target_srec_flavour, 5785 bfd_target_verilog_flavour, 5786 bfd_target_ihex_flavour, 5787 bfd_target_som_flavour, 5788 bfd_target_os9k_flavour, 5789 bfd_target_versados_flavour, 5790 bfd_target_msdos_flavour, 5791 bfd_target_ovax_flavour, 5792 bfd_target_evax_flavour, 5793 bfd_target_mmo_flavour, 5794 bfd_target_mach_o_flavour, 5795 bfd_target_pef_flavour, 5796 bfd_target_pef_xlib_flavour, 5797 bfd_target_sym_flavour 5798 }; 5799 5800 enum bfd_endian { BFD_ENDIAN_BIG, BFD_ENDIAN_LITTLE, BFD_ENDIAN_UNKNOWN }; 5801 5802 /* Forward declaration. */ 5803 typedef struct bfd_link_info _bfd_link_info; 5804 5805 typedef struct bfd_target 5806 { 5807 /* Identifies the kind of target, e.g., SunOS4, Ultrix, etc. */ 5808 char *name; 5809 5810 /* The "flavour" of a back end is a general indication about 5811 the contents of a file. */ 5812 enum bfd_flavour flavour; 5813 5814 /* The order of bytes within the data area of a file. */ 5815 enum bfd_endian byteorder; 5816 5817 /* The order of bytes within the header parts of a file. */ 5818 enum bfd_endian header_byteorder; 5819 5820 /* A mask of all the flags which an executable may have set - 5821 from the set `BFD_NO_FLAGS', `HAS_RELOC', ...`D_PAGED'. */ 5822 flagword object_flags; 5823 5824 /* A mask of all the flags which a section may have set - from 5825 the set `SEC_NO_FLAGS', `SEC_ALLOC', ...`SET_NEVER_LOAD'. */ 5826 flagword section_flags; 5827 5828 /* The character normally found at the front of a symbol. 5829 (if any), perhaps `_'. */ 5830 char symbol_leading_char; 5831 5832 /* The pad character for file names within an archive header. */ 5833 char ar_pad_char; 5834 5835 /* The maximum number of characters in an archive header. */ 5836 unsigned short ar_max_namelen; 5837 5838 /* Entries for byte swapping for data.

The set of default architectures is selected by the macro 6256 `SELECT_ARCHITECTURES'. This is normally set up in the 6257 `config/TARGET.mt' file of your choice. If the name is not defined, 6258 then all the architectures supported are included. 6259 6260 When BFD starts up, all the architectures are called with an 6261 initialize method. It is up to the architecture back end to insert as 6262 many items into the list of architectures as it wants to; generally 6263 this would be one for each machine and one for the default case (an 6264 item with a machine field of 0). 6265 6266 BFD's idea of an architecture is implemented in `archures.c'. 6267 6268 2.13.1 bfd_architecture 6269 ----------------------- 6270 6271 *Description* 6272 This enum gives the object file's CPU architecture, in a global 6273 sense--i.e., what processor family does it belong to? Another field 6274 indicates which processor within the family is in use. The machine 6275 gives a number which distinguishes different versions of the 6276 architecture, containing, for example, 2 and 3 for Intel i960 KA and 6277 i960 KB, and 68020 and 68030 for Motorola

Possible errors 6886 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call' 6887 error. 6888 6889 2.14.1.3 `bfd_fdopenr' 6890 ...................... 6891 6892 *Synopsis* 6893 bfd *bfd_fdopenr (const char *filename, const char *target, int fd); 6894 *Description* 6895 `bfd_fdopenr' is to `bfd_fopenr' much like `fdopen' is to `fopen'. It 6896 opens a BFD on a file already described by the FD supplied. 6897 6898 When the file is later `bfd_close'd, the file descriptor will be 6899 closed. If the caller desires that this file descriptor be cached by 6900 BFD (opened as needed, closed as needed to free descriptors for other 6901 opens), with the supplied FD used as an initial file descriptor (but 6902 subject to closure at any time), call bfd_set_cacheable(bfd, 1) on the 6903 returned BFD. The default is to assume no caching; the file descriptor 6904 will remain open until `bfd_close', and will not be affected by BFD 6905 operations on other files. 6906 6907 Possible errors are `bfd_error_no_memory', 6908 `bfd_error_invalid_target' and `bfd_error_system_call'. 6909 6910 2.14.1.4 `bfd_openstreamr' 6911 .......................... 6912 6913 *Synopsis* 6914 bfd *bfd_openstreamr (const char *, const char *, void *); 6915 *Description* 6916 Open a BFD for read access on an existing stdio stream.

The STREAM is 6939 created using OPEN_FUNC, accessed using PREAD_FUNC and destroyed using 6940 CLOSE_FUNC. 6941 6942 Calls `bfd_find_target', so TARGET is interpreted as by that 6943 function. 6944 6945 Calls OPEN_FUNC (which can call `bfd_zalloc' and `bfd_get_filename') 6946 to obtain the read-only stream backing the BFD. OPEN_FUNC either 6947 succeeds returning the non-`NULL' STREAM, or fails returning `NULL' 6948 (setting `bfd_error'). 6949 6950 Calls PREAD_FUNC to request NBYTES of data from STREAM starting at 6951 OFFSET (e.g., via a call to `bfd_read'). PREAD_FUNC either succeeds 6952 returning the number of bytes read (which can be less than NBYTES when 6953 end-of-file), or fails returning -1 (setting `bfd_error'). 6954 6955 Calls CLOSE_FUNC when the BFD is later closed using `bfd_close'. 6956 CLOSE_FUNC either succeeds returning 0, or fails returning -1 (setting 6957 `bfd_error'). 6958 6959 Calls STAT_FUNC to fill in a stat structure for bfd_stat, 6960 bfd_get_size, and bfd_get_mtime calls. STAT_FUNC returns 0 on success, 6961 or returns -1 on failure (setting `bfd_error'). 6962 6963 If `bfd_openr_iovec' returns `NULL' then an error has occurred. 6964 Possible errors are `bfd_error_no_memory', `bfd_error_invalid_target' 6965 and `bfd_error_system_call'. 6966 6967 2.14.1.6 `bfd_openw' 6968 .................... 6969 6970 *Synopsis* 6971 bfd *bfd_openw (const char *filename, const char *target); 6972 *Description* 6973 Create a BFD, associated with file FILENAME, using the file format 6974 TARGET, and return a pointer to it. 6975 6976 Possible errors are `bfd_error_system_call', `bfd_error_no_memory', 6977 `bfd_error_invalid_target'. 6978 6979 2.14.1.7 `bfd_close' 6980 .................... 6981 6982 *Synopsis* 6983 bfd_boolean bfd_close (bfd *abfd); 6984 *Description* 6985 Close a BFD.

The mangling performs any necessary endian 7217 translations and removes alignment restrictions. Note that types 7218 accepted and returned by these macros are identical so they can be 7219 swapped around in macros--for example, `libaout.h' defines `GET_WORD' 7220 to either `bfd_get_32' or `bfd_get_64'. 7221 7222 In the put routines, VAL must be a `bfd_vma'. If we are on a system 7223 without prototypes, the caller is responsible for making sure that is 7224 true, with a cast if necessary. We don't cast them in the macro 7225 definitions because that would prevent `lint' or `gcc -Wall' from 7226 detecting sins such as passing a pointer. To detect calling these with 7227 less than a `bfd_vma', use `gcc -Wconversion' on a host with 64 bit 7228 `bfd_vma''s. 7229 7230 /* Byte swapping macros for user section data. */ 7231 7232 #define bfd_put_8(abfd, val, ptr) \ 7233 ((void) (*((unsigned char *) (ptr)) = (val) & 0xff)) 7234 #define bfd_put_signed_8 \ 7235 bfd_put_8 7236 #define bfd_get_8(abfd, ptr) \ 7237 (*(unsigned char *) (ptr) & 0xff) 7238 #define bfd_get_signed_8(abfd, ptr) \ 7239 (((*(unsigned char *) (ptr) & 0xff) ^ 0x80) - 0x80) 7240 7241 #define bfd_put_16(abfd, val, ptr) \ 7242 BFD_SEND (abfd, bfd_putx16, ((val),(ptr))) 7243 #define bfd_put_signed_16 \ 7244 bfd_put_16 7245 #define bfd_get_16(abfd, ptr) \ 7246 BFD_SEND (abfd, bfd_getx16, (ptr)) 7247 #define bfd_get_signed_16(abfd, ptr) \ 7248 BFD_SEND (abfd, bfd_getx_signed_16, (ptr)) 7249 7250 #define bfd_put_32(abfd, val, ptr) \ 7251 BFD_SEND (abfd, bfd_putx32, ((val),(ptr))) 7252 #define bfd_put_signed_32 \ 7253 bfd_put_32 7254 #define bfd_get_32(abfd, ptr) \ 7255 BFD_SEND (abfd, bfd_getx32, (ptr)) 7256 #define bfd_get_signed_32(abfd, ptr) \ 7257 BFD_SEND (abfd, bfd_getx_signed_32, (ptr)) 7258 7259 #define bfd_put_64(abfd, val, ptr) \ 7260 BFD_SEND (abfd, bfd_putx64, ((val), (ptr))) 7261 #define bfd_put_signed_64 \ 7262 bfd_put_64 7263 #define bfd_get_64(abfd, ptr) \ 7264 BFD_SEND (abfd, bfd_getx64, (ptr)) 7265 #define bfd_get_signed_64(abfd, ptr) \ 7266 BFD_SEND (abfd, bfd_getx_signed_64, (ptr)) 7267 7268 #define bfd_get(bits, abfd, ptr) \ 7269 ((bits) == 8 ?

The module in `cache.c' maintains a least recently used 7368 list of `BFD_CACHE_MAX_OPEN' files, and exports the name 7369 `bfd_cache_lookup', which runs around and makes sure that the required 7370 BFD is open. If not, then it chooses a file to close, closes it and 7371 opens the one wanted, returning its file handle. 7372 7373 2.16.1 Caching functions 7374 ------------------------ 7375 7376 2.16.1.1 `bfd_cache_init' 7377 ......................... 7378 7379 *Synopsis* 7380 bfd_boolean bfd_cache_init (bfd *abfd); 7381 *Description* 7382 Add a newly opened BFD to the cache. 7383 7384 2.16.1.2 `bfd_cache_close' 7385 .......................... 7386 7387 *Synopsis* 7388 bfd_boolean bfd_cache_close (bfd *abfd); 7389 *Description* 7390 Remove the BFD ABFD from the cache.

The third routine takes all the object files and links them 7437 together to create the output file. These routines are designed so 7438 that the linker proper does not need to know anything about the symbols 7439 in the object files that it is linking. The linker merely arranges the 7440 sections as directed by the linker script and lets BFD handle the 7441 details of symbols and relocs. 7442 7443 The second routine and third routines are passed a pointer to a 7444 `struct bfd_link_info' structure (defined in `bfdlink.h') which holds 7445 information relevant to the link, including the linker hash table 7446 (which was created by the first routine) and a set of callback 7447 functions to the linker proper. 7448 7449 The generic linker routines are in `linker.c', and use the header 7450 file `genlink.h'. As of this writing, the only back ends which have 7451 implemented versions of these routines are a.out (in `aoutx.h') and 7452 ECOFF (in `ecoff.c').

This 7470 entry point is called using the target vector of the linker output file. 7471 7472 The `_bfd_link_hash_table_create' entry point must allocate and 7473 initialize an instance of the desired hash table. If the back end does 7474 not require any additional information to be stored with the entries in 7475 the hash table, the entry point may simply create a `struct 7476 bfd_link_hash_table'. Most likely, however, some additional 7477 information will be needed. 7478 7479 For example, with each entry in the hash table the a.out linker 7480 keeps the index the symbol has in the final output file (this index 7481 number is used so that when doing a relocatable link the symbol index 7482 used in the output file can be quickly filled in when copying over a 7483 reloc). The a.out linker code defines the required structures and 7484 functions for a hash table derived from `struct bfd_link_hash_table'. 7485 The a.out linker hash table is created by the function 7486 `NAME(aout,link_hash_table_create)'; it simply allocates space for the 7487 hash table, initializes it, and returns a pointer to it. 7488 7489 When writing the linker routines for a new back end, you will 7490 generally not know exactly which fields will be required until you have 7491 finished. You should simply create a new hash table which defines no 7492 additional fields, and then simply add fields as they become necessary. 7493 7494 7495 File: bfd.info, Node: Adding Symbols to the Hash Table, Next: Performing the Final Link, Prev: Creating a Linker Hash Table, Up: Linker Functions 7496 7497 2.17.2 Adding symbols to the hash table 7498 --------------------------------------- 7499 7500 The linker proper will call the `_bfd_link_add_symbols' entry point for 7501 each object file or archive which is to be linked (typically these are 7502 the files named on the command line, but some may also come from the 7503 linker script). The entry point is responsible for examining the file. 7504 For an object file, BFD must add any relevant symbol information to the 7505 hash table. For an archive, BFD must determine which elements of the 7506 archive should be used and adding them to the link. 7507 7508 The a.out version of this entry point is 7509 `NAME(aout,link_add_symbols)'. 7510 7511 * Menu: 7512 7513 * Differing file formats:: 7514 * Adding symbols from an object file:: 7515 * Adding symbols from an archive:: 7516 7517 7518 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 7519 7520 2.17.2.1 Differing file formats 7521 ............................... 7522 7523 Normally all the files involved in a link will be of the same format, 7524 but it is also possible to link together different format object files, 7525 and the back end must support that. The `_bfd_link_add_symbols' entry 7526 point is called via the target vector of the file to be added. This 7527 has an important consequence: the function may not assume that the hash 7528 table is the type created by the corresponding 7529 `_bfd_link_hash_table_create' vector. All the `_bfd_link_add_symbols' 7530 function can assume about the hash table is that it is derived from 7531 `struct bfd_link_hash_table'. 7532 7533 Sometimes the `_bfd_link_add_symbols' function must store some 7534 information in the hash table entry to be used by the `_bfd_final_link' 7535 function. In such a case the output bfd xvec must be checked to make 7536 sure that the hash table was created by an object file of the same 7537 format. 7538 7539 The `_bfd_final_link' routine must be prepared to handle a hash 7540 entry without any extra information added by the 7541 `_bfd_link_add_symbols' function. A hash entry without extra 7542 information will also occur when the linker script directs the linker 7543 to create a symbol. Note that, regardless of how a hash table entry is 7544 added, all the fields will be initialized to some sort of null value by 7545 the hash table entry initialization function. 7546 7547 See `ecoff_link_add_externals' for an example of how to check the 7548 output bfd before saving information (in this case, the ECOFF external 7549 symbol debugging information) in a hash table entry. 7550 7551 7552 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 7553 7554 2.17.2.2 Adding symbols from an object file 7555 ........................................... 7556 7557 When the `_bfd_link_add_symbols' routine is passed an object file, it 7558 must add all externally visible symbols in that object file to the hash 7559 table. The actual work of adding the symbol to the hash table is 7560 normally handled by the function `_bfd_generic_link_add_one_symbol'. 7561 The `_bfd_link_add_symbols' routine is responsible for reading all the 7562 symbols from the object file and passing the correct information to 7563 `_bfd_generic_link_add_one_symbol'. 7564 7565 The `_bfd_link_add_symbols' routine should not use 7566 `bfd_canonicalize_symtab' to read the symbols. The point of providing 7567 this routine is to avoid the overhead of converting the symbols into 7568 generic `asymbol' structures. 7569 7570 `_bfd_generic_link_add_one_symbol' handles the details of combining 7571 common symbols, warning about multiple definitions, and so forth. It 7572 takes arguments which describe the symbol to add, notably symbol flags, 7573 a section, and an offset. The symbol flags include such things as 7574 `BSF_WEAK' or `BSF_INDIRECT'. The section is a section in the object 7575 file, or something like `bfd_und_section_ptr' for an undefined symbol 7576 or `bfd_com_section_ptr' for a common symbol. 7577 7578 If the `_bfd_final_link' routine is also going to need to read the 7579 symbol information, the `_bfd_link_add_symbols' routine should save it 7580 somewhere attached to the object file BFD. However, the information 7581 should only be saved if the `keep_memory' field of the `info' argument 7582 is TRUE, so that the `-no-keep-memory' linker switch is effective. 7583 7584 The a.out function which adds symbols from an object file is 7585 `aout_link_add_object_symbols', and most of the interesting work is in 7586 `aout_link_add_symbols'. The latter saves pointers to the hash tables 7587 entries created by `_bfd_generic_link_add_one_symbol' indexed by symbol 7588 number, so that the `_bfd_final_link' routine does not have to call the 7589 hash table lookup routine to locate the entry. 7590 7591 7592 File: bfd.info, Node: Adding symbols from an archive, Prev: Adding symbols from an object file, Up: Adding Symbols to the Hash Table 7593 7594 2.17.2.3 Adding symbols from an archive 7595 ....................................... 7596 7597 When the `_bfd_link_add_symbols' routine is passed an archive, it must 7598 look through the symbols defined by the archive and decide which 7599 elements of the archive should be included in the link. For each such 7600 element it must call the `add_archive_element' linker callback, and it 7601 must add the symbols from the object file to the linker hash table. 7602 7603 In most cases the work of looking through the symbols in the archive 7604 should be done by the `_bfd_generic_link_add_archive_symbols' function. 7605 This function builds a hash table from the archive symbol table and 7606 looks through the list of undefined symbols to see which elements 7607 should be included. `_bfd_generic_link_add_archive_symbols' is passed 7608 a function to call to make the final decision about adding an archive 7609 element to the link and to do the actual work of adding the symbols to 7610 the linker hash table. 7611 7612 The function passed to `_bfd_generic_link_add_archive_symbols' must 7613 read the symbols of the archive element and decide whether the archive 7614 element should be included in the link. If the element is to be 7615 included, the `add_archive_element' linker callback routine must be 7616 called with the element as an argument, and the elements symbols must 7617 be added to the linker hash table just as though the element had itself 7618 been passed to the `_bfd_link_add_symbols' function. 7619 7620 When the a.out `_bfd_link_add_symbols' function receives an archive, 7621 it calls `_bfd_generic_link_add_archive_symbols' passing 7622 `aout_link_check_archive_element' as the function argument. 7623 `aout_link_check_archive_element' calls `aout_link_check_ar_symbols'. 7624 If the latter decides to add the element (an element is only added if 7625 it provides a real, non-common, definition for a previously undefined 7626 or common symbol) it calls the `add_archive_element' callback and then 7627 `aout_link_check_archive_element' calls `aout_link_add_symbols' to 7628 actually add the symbols to the linker hash table. 7629 7630 The ECOFF back end is unusual in that it does not normally call 7631 `_bfd_generic_link_add_archive_symbols', because ECOFF archives already 7632 contain a hash table of symbols. The ECOFF back end searches the 7633 archive itself to avoid the overhead of creating a new hash table. 7634 7635 7636 File: bfd.info, Node: Performing the Final Link, Prev: Adding Symbols to the Hash Table, Up: Linker Functions 7637 7638 2.17.3 Performing the final link 7639 -------------------------------- 7640 7641 When all the input files have been processed, the linker calls the 7642 `_bfd_final_link' entry point of the output BFD. This routine is 7643 responsible for producing the final output file, which has several 7644 aspects. It must relocate the contents of the input sections and copy 7645 the data into the output sections. It must build an output symbol 7646 table including any local symbols from the input files and the global 7647 symbols from the hash table. When producing relocatable output, it must 7648 modify the input relocs and write them into the output file. There may 7649 also be object format dependent work to be done. 7650 7651 The linker will also call the `write_object_contents' entry point 7652 when the BFD is closed. The two entry points must work together in 7653 order to produce the correct output file. 7654 7655 The details of how this works are inevitably dependent upon the 7656 specific object file format. The a.out `_bfd_final_link' routine is 7657 `NAME(aout,final_link)'. 7658 7659 * Menu: 7660 7661 * Information provided by the linker:: 7662 * Relocating the section contents:: 7663 * Writing the symbol table:: 7664 7665 7666 File: bfd.info, Node: Information provided by the linker, Next: Relocating the section contents, Prev: Performing the Final Link, Up: Performing the Final Link 7667 7668 2.17.3.1 Information provided by the linker 7669 ........................................... 7670 7671 Before the linker calls the `_bfd_final_link' entry point, it sets up 7672 some data structures for the function to use. 7673 7674 The `input_bfds' field of the `bfd_link_info' structure will point 7675 to a list of all the input files included in the link. These files are 7676 linked through the `link_next' field of the `bfd' structure. 7677 7678 Each section in the output file will have a list of `link_order' 7679 structures attached to the `map_head.link_order' field (the 7680 `link_order' structure is defined in `bfdlink.h'). These structures 7681 describe how to create the contents of the output section in terms of 7682 the contents of various input sections, fill constants, and, 7683 eventually, other types of information. They also describe relocs that 7684 must be created by the BFD backend, but do not correspond to any input 7685 file; this is used to support -Ur, which builds constructors while 7686 generating a relocatable object file. 7687 7688 7689 File: bfd.info, Node: Relocating the section contents, Next: Writing the symbol table, Prev: Information provided by the linker, Up: Performing the Final Link 7690 7691 2.17.3.2 Relocating the section contents 7692 ........................................ 7693 7694 The `_bfd_final_link' function should look through the `link_order' 7695 structures attached to each section of the output file. Each 7696 `link_order' structure should either be handled specially, or it should 7697 be passed to the function `_bfd_default_link_order' which will do the 7698 right thing (`_bfd_default_link_order' is defined in `linker.c'). 7699 7700 For efficiency, a `link_order' of type `bfd_indirect_link_order' 7701 whose associated section belongs to a BFD of the same format as the 7702 output BFD must be handled specially. This type of `link_order' 7703 describes part of an output section in terms of a section belonging to 7704 one of the input files. The `_bfd_final_link' function should read the 7705 contents of the section and any associated relocs, apply the relocs to 7706 the section contents, and write out the modified section contents. If 7707 performing a relocatable link, the relocs themselves must also be 7708 modified and written out. 7709 7710 The functions `_bfd_relocate_contents' and 7711 `_bfd_final_link_relocate' provide some general support for performing 7712 the actual relocations, notably overflow checking. Their arguments 7713 include information about the symbol the relocation is against and a 7714 `reloc_howto_type' argument which describes the relocation to perform. 7715 These functions are defined in `reloc.c'. 7716 7717 The a.out function which handles reading, relocating, and writing 7718 section contents is `aout_link_input_section'. The actual relocation 7719 is done in `aout_link_input_section_std' and 7720 `aout_link_input_section_ext'. 7721 7722 7723 File: bfd.info, Node: Writing the symbol table, Prev: Relocating the section contents, Up: Performing the Final Link 7724 7725 2.17.3.3 Writing the symbol table 7726 ................................. 7727 7728 The `_bfd_final_link' function must gather all the symbols in the input 7729 files and write them out. It must also write out all the symbols in 7730 the global hash table. This must be controlled by the `strip' and 7731 `discard' fields of the `bfd_link_info' structure. 7732 7733 The local symbols of the input files will not have been entered into 7734 the linker hash table. The `_bfd_final_link' routine must consider 7735 each input file and include the symbols in the output file. It may be 7736 convenient to do this when looking through the `link_order' structures, 7737 or it may be done by stepping through the `input_bfds' list. 7738 7739 The `_bfd_final_link' routine must also traverse the global hash 7740 table to gather all the externally visible symbols. It is possible 7741 that most of the externally visible symbols may be written out when 7742 considering the symbols of each input file, but it is still necessary 7743 to traverse the hash table since the linker script may have defined 7744 some symbols that are not in any of the input files. 7745 7746 The `strip' field of the `bfd_link_info' structure controls which 7747 symbols are written out. The possible values are listed in 7748 `bfdlink.h'. If the value is `strip_some', then the `keep_hash' field 7749 of the `bfd_link_info' structure is a hash table of symbols to keep; 7750 each symbol should be looked up in this hash table, and only symbols 7751 which are present should be included in the output file. 7752 7753 If the `strip' field of the `bfd_link_info' structure permits local 7754 symbols to be written out, the `discard' field is used to further 7755 controls which local symbols are included in the output file. If the 7756 value is `discard_l', then all local symbols which begin with a certain 7757 prefix are discarded; this is controlled by the 7758 `bfd_is_local_label_name' entry point. 7759 7760 The a.out backend handles symbols by calling 7761 `aout_link_write_symbols' on each input BFD and then traversing the 7762 global hash table with the function `aout_link_write_other_symbol'. It 7763 builds a string table while writing out the symbols, which is written 7764 to the output file at the end of `NAME(aout,final_link)'. 7765 7766 2.17.3.4 `bfd_link_split_section' 7767 ................................. 7768 7769 *Synopsis* 7770 bfd_boolean bfd_link_split_section (bfd *abfd, asection *sec); 7771 *Description* 7772 Return nonzero if SEC should be split during a reloceatable or final 7773 link. 7774 #define bfd_link_split_section(abfd, sec) \ 7775 BFD_SEND (abfd, _bfd_link_split_section, (abfd, sec)) 7776 7777 2.17.3.5 `bfd_section_already_linked' 7778 ..................................... 7779 7780 *Synopsis* 7781 void bfd_section_already_linked (bfd *abfd, asection *sec, 7782 struct bfd_link_info *info); 7783 *Description* 7784 Check if SEC has been already linked during a reloceatable or final 7785 link. 7786 #define bfd_section_already_linked(abfd, sec, info) \ 7787 BFD_SEND (abfd, _section_already_linked, (abfd, sec, info)) 7788 7789 2.17.3.6 `bfd_generic_define_common_symbol' 7790 ........................................... 7791 7792 *Synopsis* 7793 bfd_boolean bfd_generic_define_common_symbol 7794 (bfd *output_bfd, struct bfd_link_info *info, 7795 struct bfd_link_hash_entry *h); 7796 *Description* 7797 Convert common symbol H into a defined symbol.

Routines are 7821 provided to initialize a hash table, to free a hash table, to look up a 7822 string in a hash table and optionally create an entry for it, and to 7823 traverse a hash table. There is currently no routine to delete an 7824 string from a hash table. 7825 7826 The basic hash table does not permit any data to be stored with a 7827 string. However, a hash table is designed to present a base class from 7828 which other types of hash tables may be derived. These derived types 7829 may store additional information with the string. Hash tables were 7830 implemented in this way, rather than simply providing a data pointer in 7831 a hash table entry, because they were designed for use by the linker 7832 back ends. The linker may create thousands of hash table entries, and 7833 the overhead of allocating private data and storing and following 7834 pointers becomes noticeable. 7835 7836 The basic hash table code is in `hash.c'. 7837 7838 * Menu: 7839 7840 * Creating and Freeing a Hash Table:: 7841 * Looking Up or Entering a String:: 7842 * Traversing a Hash Table:: 7843 * Deriving a New Hash Table Type:: 7844 7845 7846 File: bfd.info, Node: Creating and Freeing a Hash Table, Next: Looking Up or Entering a String, Prev: Hash Tables, Up: Hash Tables 7847 7848 2.18.1 Creating and freeing a hash table 7849 ---------------------------------------- 7850 7851 To create a hash table, create an instance of a `struct bfd_hash_table' 7852 (defined in `bfd.h') and call `bfd_hash_table_init' (if you know 7853 approximately how many entries you will need, the function 7854 `bfd_hash_table_init_n', which takes a SIZE argument, may be used). 7855 `bfd_hash_table_init' returns `FALSE' if some sort of error occurs. 7856 7857 The function `bfd_hash_table_init' take as an argument a function to 7858 use to create new entries. For a basic hash table, use the function 7859 `bfd_hash_newfunc'. *Note Deriving a New Hash Table Type::, for why 7860 you would want to use a different value for this argument. 7861 7862 `bfd_hash_table_init' will create an objalloc which will be used to 7863 allocate new entries. You may allocate memory on this objalloc using 7864 `bfd_hash_allocate'. 7865 7866 Use `bfd_hash_table_free' to free up all the memory that has been 7867 allocated for a hash table. This will not free up the `struct 7868 bfd_hash_table' itself, which you must provide. 7869 7870 Use `bfd_hash_set_default_size' to set the default size of hash 7871 table to use. 7872 7873 7874 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 7875 7876 2.18.2 Looking up or entering a string 7877 -------------------------------------- 7878 7879 The function `bfd_hash_lookup' is used both to look up a string in the 7880 hash table and to create a new entry. 7881 7882 If the CREATE argument is `FALSE', `bfd_hash_lookup' will look up a 7883 string. If the string is found, it will returns a pointer to a `struct 7884 bfd_hash_entry'. If the string is not found in the table 7885 `bfd_hash_lookup' will return `NULL'. You should not modify any of the 7886 fields in the returns `struct bfd_hash_entry'. 7887 7888 If the CREATE argument is `TRUE', the string will be entered into 7889 the hash table if it is not already there. Either way a pointer to a 7890 `struct bfd_hash_entry' will be returned, either to the existing 7891 structure or to a newly created one. In this case, a `NULL' return 7892 means that an error occurred. 7893 7894 If the CREATE argument is `TRUE', and a new entry is created, the 7895 COPY argument is used to decide whether to copy the string onto the 7896 hash table objalloc or not. If COPY is passed as `FALSE', you must be 7897 careful not to deallocate or modify the string as long as the hash table 7898 exists. 7899 7900 7901 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 7902 7903 2.18.3 Traversing a hash table 7904 ------------------------------ 7905 7906 The function `bfd_hash_traverse' may be used to traverse a hash table, 7907 calling a function on each element. The traversal is done in a random 7908 order. 7909 7910 `bfd_hash_traverse' takes as arguments a function and a generic 7911 `void *' pointer. The function is called with a hash table entry (a 7912 `struct bfd_hash_entry *') and the generic pointer passed to 7913 `bfd_hash_traverse'. The function must return a `boolean' value, which 7914 indicates whether to continue traversing the hash table. If the 7915 function returns `FALSE', `bfd_hash_traverse' will stop the traversal 7916 and return immediately. 7917 7918 7919 File: bfd.info, Node: Deriving a New Hash Table Type, Prev: Traversing a Hash Table, Up: Hash Tables 7920 7921 2.18.4 Deriving a new hash table type 7922 ------------------------------------- 7923 7924 Many uses of hash tables want to store additional information which 7925 each entry in the hash table. Some also find it convenient to store 7926 additional information with the hash table itself. This may be done 7927 using a derived hash table. 7928 7929 Since C is not an object oriented language, creating a derived hash 7930 table requires sticking together some boilerplate routines with a few 7931 differences specific to the type of hash table you want to create. 7932 7933 An example of a derived hash table is the linker hash table. The 7934 structures for this are defined in `bfdlink.h'. The functions are in 7935 `linker.c'. 7936 7937 You may also derive a hash table from an already derived hash table. 7938 For example, the a.out linker backend code uses a hash table derived 7939 from the linker hash table. 7940 7941 * Menu: 7942 7943 * Define the Derived Structures:: 7944 * Write the Derived Creation Routine:: 7945 * Write Other Derived Routines:: 7946 7947 7948 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 7949 7950 2.18.4.1 Define the derived structures 7951 ...................................... 7952 7953 You must define a structure for an entry in the hash table, and a 7954 structure for the hash table itself. 7955 7956 The first field in the structure for an entry in the hash table must 7957 be of the type used for an entry in the hash table you are deriving 7958 from. If you are deriving from a basic hash table this is `struct 7959 bfd_hash_entry', which is defined in `bfd.h'. The first field in the 7960 structure for the hash table itself must be of the type of the hash 7961 table you are deriving from itself. If you are deriving from a basic 7962 hash table, this is `struct bfd_hash_table'. 7963 7964 For example, the linker hash table defines `struct 7965 bfd_link_hash_entry' (in `bfdlink.h'). The first field, `root', is of 7966 type `struct bfd_hash_entry'. Similarly, the first field in `struct 7967 bfd_link_hash_table', `table', is of type `struct bfd_hash_table'. 7968 7969 7970 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 7971 7972 2.18.4.2 Write the derived creation routine 7973 ........................................... 7974 7975 You must write a routine which will create and initialize an entry in 7976 the hash table. This routine is passed as the function argument to 7977 `bfd_hash_table_init'. 7978 7979 In order to permit other hash tables to be derived from the hash 7980 table you are creating, this routine must be written in a standard way. 7981 7982 The first argument to the creation routine is a pointer to a hash 7983 table entry. This may be `NULL', in which case the routine should 7984 allocate the right amount of space. Otherwise the space has already 7985 been allocated by a hash table type derived from this one. 7986 7987 After allocating space, the creation routine must call the creation 7988 routine of the hash table type it is derived from, passing in a pointer 7989 to the space it just allocated. This will initialize any fields used 7990 by the base hash table. 7991 7992 Finally the creation routine must initialize any local fields for 7993 the new hash table type. 7994 7995 Here is a boilerplate example of a creation routine. FUNCTION_NAME 7996 is the name of the routine. ENTRY_TYPE is the type of an entry in the 7997 hash table you are creating. BASE_NEWFUNC is the name of the creation 7998 routine of the hash table type your hash table is derived from. 7999 8000 struct bfd_hash_entry * 8001 FUNCTION_NAME (struct bfd_hash_entry *entry, 8002 struct bfd_hash_table *table, 8003 const char *string) 8004 { 8005 struct ENTRY_TYPE *ret = (ENTRY_TYPE *) entry; 8006 8007 /* Allocate the structure if it has not already been allocated by a 8008 derived class. */ 8009 if (ret == NULL) 8010 { 8011 ret = bfd_hash_allocate (table, sizeof (* ret)); 8012 if (ret == NULL) 8013 return NULL; 8014 } 8015 8016 /* Call the allocation method of the base class. */ 8017 ret = ((ENTRY_TYPE *) 8018 BASE_NEWFUNC ((struct bfd_hash_entry *) ret, table, string)); 8019 8020 /* Initialize the local fields here. */ 8021 8022 return (struct bfd_hash_entry *) ret; 8023 } 8024 *Description* 8025 The creation routine for the linker hash table, which is in `linker.c', 8026 looks just like this example. FUNCTION_NAME is 8027 `_bfd_link_hash_newfunc'. ENTRY_TYPE is `struct bfd_link_hash_entry'. 8028 BASE_NEWFUNC is `bfd_hash_newfunc', the creation routine for a basic 8029 hash table. 8030 8031 `_bfd_link_hash_newfunc' also initializes the local fields in a 8032 linker hash table entry: `type', `written' and `next'. 8033 8034 8035 File: bfd.info, Node: Write Other Derived Routines, Prev: Write the Derived Creation Routine, Up: Deriving a New Hash Table Type 8036 8037 2.18.4.3 Write other derived routines 8038 ..................................... 8039 8040 You will want to write other routines for your new hash table, as well. 8041 8042 You will want an initialization routine which calls the 8043 initialization routine of the hash table you are deriving from and 8044 initializes any other local fields. For the linker hash table, this is 8045 `_bfd_link_hash_table_init' in `linker.c'. 8046 8047 You will want a lookup routine which calls the lookup routine of the 8048 hash table you are deriving from and casts the result. The linker hash 8049 table uses `bfd_link_hash_lookup' in `linker.c' (this actually takes an 8050 additional argument which it uses to decide how to return the looked up 8051 value). 8052 8053 You may want a traversal routine. This should just call the 8054 traversal routine of the hash table you are deriving from with 8055 appropriate casts. The linker hash table uses `bfd_link_hash_traverse' 8056 in `linker.c'. 8057 8058 These routines may simply be defined as macros. For example, the 8059 a.out backend linker hash table, which is derived from the linker hash 8060 table, uses macros for the lookup and traversal routines. These are 8061 `aout_link_hash_lookup' and `aout_link_hash_traverse' in aoutx.h. 8062 8063 8064 File: bfd.info, Node: BFD back ends, Next: GNU Free Documentation License, Prev: BFD front end, Up: Top 8065 8066 3 BFD back ends 8067 *************** 8068 8069 * Menu: 8070 8071 * What to Put Where:: 8072 * aout :: a.out backends 8073 * coff :: coff backends 8074 * elf :: elf backends 8075 * mmo :: mmo backend 8076 8077 8078 File: bfd.info, Node: What to Put Where, Next: aout, Prev: BFD back ends, Up: BFD back ends 8079 8080 3.1 What to Put Where 8081 ===================== 8082 8083 All of BFD lives in one directory. 8084 8085 8086 File: bfd.info, Node: aout, Next: coff, Prev: What to Put Where, Up: BFD back ends 8087 8088 3.2 a.out backends 8089 ================== 8090 8091 *Description* 8092 BFD supports a number of different flavours of a.out format, though the 8093 major differences are only the sizes of the structures on disk, and the 8094 shape of the relocation information. 8095 8096 The support is split into a basic support file `aoutx.h' and other 8097 files which derive functions from the base. One derivation file is 8098 `aoutf1.h' (for a.out flavour 1), and adds to the basic a.out functions 8099 support for sun3, sun4, 386 and 29k a.out files, to create a target 8100 jump vector for a specific target. 8101 8102 This information is further split out into more specific files for 8103 each machine, including `sunos.c' for sun3 and sun4, `newsos3.c' for 8104 the Sony NEWS, and `demo64.c' for a demonstration of a 64 bit a.out 8105 format. 8106 8107 The base file `aoutx.h' defines general mechanisms for reading and 8108 writing records to and from disk and various other methods which BFD 8109 requires. It is included by `aout32.c' and `aout64.c' to form the names 8110 `aout_32_swap_exec_header_in', `aout_64_swap_exec_header_in', etc. 8111 8112 As an example, this is what goes on to make the back end for a sun4, 8113 from `aout32.c': 8114 8115 #define ARCH_SIZE 32 8116 #include "aoutx.h" 8117 8118 Which exports names: 8119 8120 ... 8121 aout_32_canonicalize_reloc 8122 aout_32_find_nearest_line 8123 aout_32_get_lineno 8124 aout_32_get_reloc_upper_bound 8125 ... 8126 8127 from `sunos.c': 8128 8129 #define TARGET_NAME "a.out-sunos-big" 8130 #define VECNAME sunos_big_vec 8131 #include "aoutf1.h" 8132 8133 requires all the names from `aout32.c', and produces the jump vector 8134 8135 sunos_big_vec 8136 8137 The file `host-aout.c' is a special case. It is for a large set of 8138 hosts that use "more or less standard" a.out files, and for which 8139 cross-debugging is not interesting. It uses the standard 32-bit a.out 8140 support routines, but determines the file offsets and addresses of the 8141 text, data, and BSS sections, the machine architecture and machine 8142 type, and the entry point address, in a host-dependent manner. Once 8143 these values have been determined, generic code is used to handle the 8144 object file. 8145 8146 When porting it to run on a new system, you must supply: 8147 8148 HOST_PAGE_SIZE 8149 HOST_SEGMENT_SIZE 8150 HOST_MACHINE_ARCH (optional) 8151 HOST_MACHINE_MACHINE (optional) 8152 HOST_TEXT_START_ADDR 8153 HOST_STACK_END_ADDR 8154 8155 in the file `../include/sys/h-XXX.h' (for your host). These values, 8156 plus the structures and macros defined in `a.out.h' on your host 8157 system, will produce a BFD target that will access ordinary a.out files 8158 on your host. To configure a new machine to use `host-aout.c', specify: 8159 8160 TDEFAULTS = -DDEFAULT_VECTOR=host_aout_big_vec 8161 TDEPFILES= host-aout.o trad-core.o 8162 8163 in the `config/XXX.mt' file, and modify `configure.in' to use the 8164 `XXX.mt' file (by setting "`bfd_target=XXX'") when your configuration 8165 is selected. 8166 8167 3.2.1 Relocations 8168 ----------------- 8169 8170 *Description* 8171 The file `aoutx.h' provides for both the _standard_ and _extended_ 8172 forms of a.out relocation records. 8173 8174 The standard records contain only an address, a symbol index, and a 8175 type field. The extended records (used on 29ks and sparcs) also have a 8176 full integer for an addend. 8177 8178 3.2.2 Internal entry points 8179 --------------------------- 8180 8181 *Description* 8182 `aoutx.h' exports several routines for accessing the contents of an 8183 a.out file, which are gathered and exported in turn by various format 8184 specific files (eg sunos.c). 8185 8186 3.2.2.1 `aout_SIZE_swap_exec_header_in' 8187 ....................................... 8188 8189 *Synopsis* 8190 void aout_SIZE_swap_exec_header_in, 8191 (bfd *abfd, 8192 struct external_exec *bytes, 8193 struct internal_exec *execp); 8194 *Description* 8195 Swap the information in an executable header RAW_BYTES taken from a raw 8196 byte stream memory image into the internal exec header structure EXECP. 8197 8198 3.2.2.2 `aout_SIZE_swap_exec_header_out' 8199 ........................................ 8200 8201 *Synopsis* 8202 void aout_SIZE_swap_exec_header_out 8203 (bfd *abfd, 8204 struct internal_exec *execp, 8205 struct external_exec *raw_bytes); 8206 *Description* 8207 Swap the information in an internal exec header structure EXECP into 8208 the buffer RAW_BYTES ready for writing to disk. 8209 8210 3.2.2.3 `aout_SIZE_some_aout_object_p' 8211 ...................................... 8212 8213 *Synopsis* 8214 const bfd_target *aout_SIZE_some_aout_object_p 8215 (bfd *abfd, 8216 struct internal_exec *execp, 8217 const bfd_target *(*callback_to_real_object_p) (bfd *)); 8218 *Description* 8219 Some a.out variant thinks that the file open in ABFD checking is an 8220 a.out file.

The major 8279 differences between formats are the sizes and alignments of fields in 8280 structures on disk, and the occasional extra field. 8281 8282 Coff in all its varieties is implemented with a few common files and 8283 a number of implementation specific files. For example, The 88k bcs 8284 coff format is implemented in the file `coff-m88k.c'. This file 8285 `#include's `coff/m88k.h' which defines the external structure of the 8286 coff format for the 88k, and `coff/internal.h' which defines the 8287 internal structure. `coff-m88k.c' also defines the relocations used by 8288 the 88k format *Note Relocations::. 8289 8290 The Intel i960 processor version of coff is implemented in 8291 `coff-i960.c'. This file has the same structure as `coff-m88k.c', 8292 except that it includes `coff/i960.h' rather than `coff-m88k.h'. 8293 8294 3.3.1 Porting to a new version of coff 8295 -------------------------------------- 8296 8297 The recommended method is to select from the existing implementations 8298 the version of coff which is most like the one you want to use. For 8299 example, we'll say that i386 coff is the one you select, and that your 8300 coff flavour is called foo. Copy `i386coff.c' to `foocoff.c', copy 8301 `../include/coff/i386.h' to `../include/coff/foo.h', and add the lines 8302 to `targets.c' and `Makefile.in' so that your new back end is used. 8303 Alter the shapes of the structures in `../include/coff/foo.h' so that 8304 they match what you need. You will probably also have to add `#ifdef's 8305 to the code in `coff/internal.h' and `coffcode.h' if your version of 8306 coff is too wild. 8307 8308 You can verify that your new BFD backend works quite simply by 8309 building `objdump' from the `binutils' directory, and making sure that 8310 its version of what's going on and your host system's idea (assuming it 8311 has the pretty standard coff dump utility, usually called `att-dump' or 8312 just `dump') are the same. Then clean up your code, and send what 8313 you've done to Cygnus. Then your stuff will be in the next release, and 8314 you won't have to keep integrating it. 8315 8316 3.3.2 How the coff backend works 8317 -------------------------------- 8318 8319 3.3.2.1 File layout 8320 ................... 8321 8322 The Coff backend is split into generic routines that are applicable to 8323 any Coff target and routines that are specific to a particular target. 8324 The target-specific routines are further split into ones which are 8325 basically the same for all Coff targets except that they use the 8326 external symbol format or use different values for certain constants. 8327 8328 The generic routines are in `coffgen.c'. These routines work for 8329 any Coff target. They use some hooks into the target specific code; 8330 the hooks are in a `bfd_coff_backend_data' structure, one of which 8331 exists for each target. 8332 8333 The essentially similar target-specific routines are in 8334 `coffcode.h'. This header file includes executable C code. The 8335 various Coff targets first include the appropriate Coff header file, 8336 make any special defines that are needed, and then include `coffcode.h'. 8337 8338 Some of the Coff targets then also have additional routines in the 8339 target source file itself. 8340 8341 For example, `coff-i960.c' includes `coff/internal.h' and 8342 `coff/i960.h'. It then defines a few constants, such as `I960', and 8343 includes `coffcode.h'. Since the i960 has complex relocation types, 8344 `coff-i960.c' also includes some code to manipulate the i960 relocs. 8345 This code is not in `coffcode.h' because it would not be used by any 8346 other target. 8347 8348 3.3.2.2 Coff long section names 8349 ............................... 8350 8351 In the standard Coff object format, section names are limited to the 8352 eight bytes available in the `s_name' field of the `SCNHDR' section 8353 header structure. The format requires the field to be NUL-padded, but 8354 not necessarily NUL-terminated, so the longest section names permitted 8355 are a full eight characters. 8356 8357 The Microsoft PE variants of the Coff object file format add an 8358 extension to support the use of long section names. This extension is 8359 defined in section 4 of the Microsoft PE/COFF specification (rev 8.1). 8360 If a section name is too long to fit into the section header's `s_name' 8361 field, it is instead placed into the string table, and the `s_name' 8362 field is filled with a slash ("/") followed by the ASCII decimal 8363 representation of the offset of the full name relative to the string 8364 table base. 8365 8366 Note that this implies that the extension can only be used in object 8367 files, as executables do not contain a string table. The standard 8368 specifies that long section names from objects emitted into executable 8369 images are to be truncated. 8370 8371 However, as a GNU extension, BFD can generate executable images that 8372 contain a string table and long section names. This would appear to be 8373 technically valid, as the standard only says that Coff debugging 8374 information is deprecated, not forbidden, and in practice it works, 8375 although some tools that parse PE files expecting the MS standard 8376 format may become confused; `PEview' is one known example. 8377 8378 The functionality is supported in BFD by code implemented under the 8379 control of the macro `COFF_LONG_SECTION_NAMES'. If not defined, the 8380 format does not support long section names in any way. If defined, it 8381 is used to initialise a flag, `_bfd_coff_long_section_names', and a 8382 hook function pointer, `_bfd_coff_set_long_section_names', in the Coff 8383 backend data structure. The flag controls the generation of long 8384 section names in output BFDs at runtime; if it is false, as it will be 8385 by default when generating an executable image, long section names are 8386 truncated; if true, the long section names extension is employed. The 8387 hook points to a function that allows the value of the flag to be 8388 altered at runtime, on formats that support long section names at all; 8389 on other formats it points to a stub that returns an error indication. 8390 With input BFDs, the flag is set according to whether any long section 8391 names are detected while reading the section headers. For a completely 8392 new BFD, the flag is set to the default for the target format. This 8393 information can be used by a client of the BFD library when deciding 8394 what output format to generate, and means that a BFD that is opened for 8395 read and subsequently converted to a writeable BFD and modified 8396 in-place will retain whatever format it had on input. 8397 8398 If `COFF_LONG_SECTION_NAMES' is simply defined (blank), or is 8399 defined to the value "1", then long section names are enabled by 8400 default; if it is defined to the value zero, they are disabled by 8401 default (but still accepted in input BFDs). The header `coffcode.h' 8402 defines a macro, `COFF_DEFAULT_LONG_SECTION_NAMES', which is used in 8403 the backends to initialise the backend data structure fields 8404 appropriately; see the comments for further detail. 8405 8406 3.3.2.3 Bit twiddling 8407 ..................... 8408 8409 Each flavour of coff supported in BFD has its own header file 8410 describing the external layout of the structures. There is also an 8411 internal description of the coff layout, in `coff/internal.h'. A major 8412 function of the coff backend is swapping the bytes and twiddling the 8413 bits to translate the external form of the structures into the normal 8414 internal form. This is all performed in the `bfd_swap'_thing_direction 8415 routines. Some elements are different sizes between different versions 8416 of coff; it is the duty of the coff version specific include file to 8417 override the definitions of various packing routines in `coffcode.h'. 8418 E.g., the size of line number entry in coff is sometimes 16 bits, and 8419 sometimes 32 bits. `#define'ing `PUT_LNSZ_LNNO' and `GET_LNSZ_LNNO' 8420 will select the correct one. No doubt, some day someone will find a 8421 version of coff which has a varying field size not catered to at the 8422 moment. To port BFD, that person will have to add more `#defines'. 8423 Three of the bit twiddling routines are exported to `gdb'; 8424 `coff_swap_aux_in', `coff_swap_sym_in' and `coff_swap_lineno_in'. `GDB' 8425 reads the symbol table on its own, but uses BFD to fix things up. More 8426 of the bit twiddlers are exported for `gas'; `coff_swap_aux_out', 8427 `coff_swap_sym_out', `coff_swap_lineno_out', `coff_swap_reloc_out', 8428 `coff_swap_filehdr_out', `coff_swap_aouthdr_out', 8429 `coff_swap_scnhdr_out'. `Gas' currently keeps track of all the symbol 8430 table and reloc drudgery itself, thereby saving the internal BFD 8431 overhead, but uses BFD to swap things on the way out, making cross 8432 ports much safer. Doing so also allows BFD (and thus the linker) to 8433 use the same header files as `gas', which makes one avenue to disaster 8434 disappear. 8435 8436 3.3.2.4 Symbol reading 8437 ...................... 8438 8439 The simple canonical form for symbols used by BFD is not rich enough to 8440 keep all the information available in a coff symbol table. The back end 8441 gets around this problem by keeping the original symbol table around, 8442 "behind the scenes". 8443 8444 When a symbol table is requested (through a call to 8445 `bfd_canonicalize_symtab'), a request gets through to 8446 `coff_get_normalized_symtab'. This reads the symbol table from the coff 8447 file and swaps all the structures inside into the internal form. It 8448 also fixes up all the pointers in the table (represented in the file by 8449 offsets from the first symbol in the table) into physical pointers to 8450 elements in the new internal table. This involves some work since the 8451 meanings of fields change depending upon context: a field that is a 8452 pointer to another structure in the symbol table at one moment may be 8453 the size in bytes of a structure at the next. Another pass is made 8454 over the table. All symbols which mark file names (`C_FILE' symbols) 8455 are modified so that the internal string points to the value in the 8456 auxent (the real filename) rather than the normal text associated with 8457 the symbol (`".file"'). 8458 8459 At this time the symbol names are moved around. Coff stores all 8460 symbols less than nine characters long physically within the symbol 8461 table; longer strings are kept at the end of the file in the string 8462 table. This pass moves all strings into memory and replaces them with 8463 pointers to the strings. 8464 8465 The symbol table is massaged once again, this time to create the 8466 canonical table used by the BFD application. Each symbol is inspected 8467 in turn, and a decision made (using the `sclass' field) about the 8468 various flags to set in the `asymbol'. *Note Symbols::. The generated 8469 canonical table shares strings with the hidden internal symbol table. 8470 8471 Any linenumbers are read from the coff file too, and attached to the 8472 symbols which own the functions the linenumbers belong to. 8473 8474 3.3.2.5 Symbol writing 8475 ...................... 8476 8477 Writing a symbol to a coff file which didn't come from a coff file will 8478 lose any debugging information. The `asymbol' structure remembers the 8479 BFD from which the symbol was taken, and on output the back end makes 8480 sure that the same destination target as source target is present. 8481 8482 When the symbols have come from a coff file then all the debugging 8483 information is preserved. 8484 8485 Symbol tables are provided for writing to the back end in a vector 8486 of pointers to pointers. This allows applications like the linker to 8487 accumulate and output large symbol tables without having to do too much 8488 byte copying. 8489 8490 This function runs through the provided symbol table and patches 8491 each symbol marked as a file place holder (`C_FILE') to point to the 8492 next file place holder in the list. It also marks each `offset' field 8493 in the list with the offset from the first symbol of the current symbol. 8494 8495 Another function of this procedure is to turn the canonical value 8496 form of BFD into the form used by coff. Internally, BFD expects symbol 8497 values to be offsets from a section base; so a symbol physically at 8498 0x120, but in a section starting at 0x100, would have the value 0x20. 8499 Coff expects symbols to contain their final value, so symbols have 8500 their values changed at this point to reflect their sum with their 8501 owning section. This transformation uses the `output_section' field of 8502 the `asymbol''s `asection' *Note Sections::. 8503 8504 * `coff_mangle_symbols' 8505 This routine runs though the provided symbol table and uses the 8506 offsets generated by the previous pass and the pointers generated when 8507 the symbol table was read in to create the structured hierarchy 8508 required by coff. It changes each pointer to a symbol into the index 8509 into the symbol table of the asymbol. 8510 8511 * `coff_write_symbols' 8512 This routine runs through the symbol table and patches up the 8513 symbols from their internal form into the coff way, calls the bit 8514 twiddlers, and writes out the table to the file. 8515 8516 3.3.2.6 `coff_symbol_type' 8517 .......................... 8518 8519 *Description* 8520 The hidden information for an `asymbol' is described in a 8521 `combined_entry_type': 8522 8523 8524 typedef struct coff_ptr_struct 8525 { 8526 /* Remembers the offset from the first symbol in the file for 8527 this symbol.

write relocations, the back end steps though the canonical 8879 relocation table and create an `internal_reloc'. The symbol index to 8880 use is removed from the `offset' field in the symbol table supplied. 8881 The address comes directly from the sum of the section base address and 8882 the relocation offset; the type is dug directly from the howto field. 8883 Then the `internal_reloc' is swapped into the shape of an 8884 `external_reloc' and written out to disk. 8885 8886 3.3.2.9 Reading linenumbers 8887 ........................... 8888 8889 Creating the linenumber table is done by reading in the entire coff 8890 linenumber table, and creating another table for internal use. 8891 8892 A coff linenumber table is structured so that each function is 8893 marked as having a line number of 0. Each line within the function is 8894 an offset from the first line in the function. The base of the line 8895 number information for the table is stored in the symbol associated 8896 with the function. 8897 8898 Note: The PE format uses line number 0 for a flag indicating a new 8899 source file. 8900 8901 The information is copied from the external to the internal table, 8902 and each symbol which marks a function is marked by pointing its... 8903 8904 How does this work ? 8905 8906 3.3.2.10 Reading relocations 8907 ............................ 8908 8909 Coff relocations are easily transformed into the internal BFD form 8910 (`arelent'). 8911 8912 Reading a coff relocation table is done in the following stages: 8913 8914 * Read the entire coff relocation table into memory. 8915 8916 * Process each relocation in turn; first swap it from the external 8917 to the internal form. 8918 8919 * Turn the symbol referenced in the relocation's symbol index into a 8920 pointer into the canonical symbol table. This table is the same 8921 as the one returned by a call to `bfd_canonicalize_symtab'. The 8922 back end will call that routine and save the result if a 8923 canonicalization hasn't been done. 8924 8925 * The reloc index is turned into a pointer to a howto structure, in 8926 a back end specific way. For instance, the 386 and 960 use the 8927 `r_type' to directly produce an index into a howto table vector; 8928 the 88k subtracts a number from the `r_type' field and creates an 8929 addend field. 8930 8931 8932 File: bfd.info, Node: elf, Next: mmo, Prev: coff, Up: BFD back ends 8933 8934 3.4 ELF backends 8935 ================ 8936 8937 BFD support for ELF formats is being worked on. Currently, the best 8938 supported back ends are for sparc and i386 (running svr4 or Solaris 2). 8939 8940 Documentation of the internals of the support code still needs to be 8941 written. The code is changing quickly enough that we haven't bothered 8942 yet. 8943 8944 8945 File: bfd.info, Node: mmo, Prev: elf, Up: BFD back ends 8946 8947 3.5 mmo backend 8948 =============== 8949 8950 The mmo object format is used exclusively together with Professor 8951 Donald E. Knuth's educational 64-bit processor MMIX. The simulator 8952 `mmix' which is available at 8953 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz' 8954 understands this format. That package also includes a combined 8955 assembler and linker called `mmixal'. The mmo format has no advantages 8956 feature-wise compared to e.g. ELF. It is a simple non-relocatable 8957 object format with no support for archives or debugging information, 8958 except for symbol value information and line numbers (which is not yet 8959 implemented in BFD). See 8960 `http://www-cs-faculty.stanford.edu/~knuth/mmix.html' for more 8961 information about MMIX. The ELF format is used for intermediate object 8962 files in the BFD implementation. 8963 8964 * Menu: 8965 8966 * File layout:: 8967 * Symbol-table:: 8968 * mmo section mapping:: 8969 8970 8971 File: bfd.info, Node: File layout, Next: Symbol-table, Prev: mmo, Up: mmo 8972 8973 3.5.1 File layout 8974 ----------------- 8975 8976 The mmo file contents is not partitioned into named sections as with 8977 e.g. ELF. Memory areas is formed by specifying the location of the 8978 data that follows. Only the memory area `0x0000...00' to `0x01ff...ff' 8979 is executable, so it is used for code (and constants) and the area 8980 `0x2000...00' to `0x20ff...ff' is used for writable data. *Note mmo 8981 section mapping::. 8982 8983 There is provision for specifying "special data" of 65536 different 8984 types. We use type 80 (decimal), arbitrarily chosen the same as the 8985 ELF `e_machine' number for MMIX, filling it with section information 8986 normally found in ELF objects. *Note mmo section mapping::. 8987 8988 Contents is entered as 32-bit words, xor:ed over previous contents, 8989 always zero-initialized. A word that starts with the byte `0x98' forms 8990 a command called a `lopcode', where the next byte distinguished between 8991 the thirteen lopcodes. The two remaining bytes, called the `Y' and `Z' 8992 fields, or the `YZ' field (a 16-bit big-endian number), are used for 8993 various purposes different for each lopcode. As documented in 8994 `http://www-cs-faculty.stanford.edu/~knuth/mmixal-intro.ps.gz', the 8995 lopcodes are: 8996 8997 `lop_quote' 8998 0x98000001. The next word is contents, regardless of whether it 8999 starts with 0x98 or not. 9000 9001 `lop_loc' 9002 0x9801YYZZ, where `Z' is 1 or 2. This is a location directive, 9003 setting the location for the next data to the next 32-bit word 9004 (for Z = 1) or 64-bit word (for Z = 2), plus Y * 2^56. Normally 9005 `Y' is 0 for the text segment and 2 for the data segment. 9006 9007 `lop_skip' 9008 0x9802YYZZ. Increase the current location by `YZ' bytes. 9009 9010 `lop_fixo' 9011 0x9803YYZZ, where `Z' is 1 or 2. Store the current location as 64 9012 bits into the location pointed to by the next 32-bit (Z = 1) or 9013 64-bit (Z = 2) word, plus Y * 2^56. 9014 9015 `lop_fixr' 9016 0x9804YYZZ. `YZ' is stored into the current location plus 2 - 4 * 9017 YZ. 9018 9019 `lop_fixrx' 9020 0x980500ZZ. `Z' is 16 or 24. A value `L' derived from the 9021 following 32-bit word are used in a manner similar to `YZ' in 9022 lop_fixr: it is xor:ed into the current location minus 4 * L. The 9023 first byte of the word is 0 or 1. If it is 1, then L = (LOWEST 24 9024 BITS OF WORD) - 2^Z, if 0, then L = (LOWEST 24 BITS OF WORD). 9025 9026 `lop_file' 9027 0x9806YYZZ. `Y' is the file number, `Z' is count of 32-bit words. 9028 Set the file number to `Y' and the line counter to 0. The next Z 9029 * 4 bytes contain the file name, padded with zeros if the count is 9030 not a multiple of four. The same `Y' may occur multiple times, 9031 but `Z' must be 0 for all but the first occurrence. 9032 9033 `lop_line' 9034 0x9807YYZZ. `YZ' is the line number. Together with lop_file, it 9035 forms the source location for the next 32-bit word. Note that for 9036 each non-lopcode 32-bit word, line numbers are assumed incremented 9037 by one. 9038 9039 `lop_spec' 9040 0x9808YYZZ. `YZ' is the type number. Data until the next lopcode 9041 other than lop_quote forms special data of type `YZ'. *Note mmo 9042 section mapping::. 9043 9044 Other types than 80, (or type 80 with a content that does not 9045 parse) is stored in sections named `.MMIX.spec_data.N' where N is 9046 the `YZ'-type. The flags for such a sections say not to allocate 9047 or load the data. The vma is 0. Contents of multiple occurrences 9048 of special data N is concatenated to the data of the previous 9049 lop_spec Ns. The location in data or code at which the lop_spec 9050 occurred is lost. 9051 9052 `lop_pre' 9053 0x980901ZZ. The first lopcode in a file. The `Z' field forms the 9054 length of header information in 32-bit words, where the first word 9055 tells the time in seconds since `00:00:00 GMT Jan 1 1970'. 9056 9057 `lop_post' 9058 0x980a00ZZ. Z > 32. This lopcode follows after all 9059 content-generating lopcodes in a program. The `Z' field denotes 9060 the value of `rG' at the beginning of the program. The following 9061 256 - Z big-endian 64-bit words are loaded into global registers 9062 `$G' ... `$255'. 9063 9064 `lop_stab' 9065 0x980b0000. The next-to-last lopcode in a program. Must follow 9066 immediately after the lop_post lopcode and its data. After this 9067 lopcode follows all symbols in a compressed format (*note 9068 Symbol-table::). 9069 9070 `lop_end' 9071 0x980cYYZZ. The last lopcode in a program. It must follow the 9072 lop_stab lopcode and its data. The `YZ' field contains the number 9073 of 32-bit words of symbol table information after the preceding 9074 lop_stab lopcode. 9075 9076 Note that the lopcode "fixups"; `lop_fixr', `lop_fixrx' and 9077 `lop_fixo' are not generated by BFD, but are handled. They are 9078 generated by `mmixal'. 9079 9080 This trivial one-label, one-instruction file: 9081 9082 :Main TRAP 1,2,3 9083 9084 can be represented this way in mmo: 9085 9086 0x98090101 - lop_pre, one 32-bit word with timestamp. 9087 <timestamp> 9088 0x98010002 - lop_loc, text segment, using a 64-bit address. 9089 Note that mmixal does not emit this for the file above. 9090 0x00000000 - Address, high 32 bits. 9091 0x00000000 - Address, low 32 bits. 9092 0x98060002 - lop_file, 2 32-bit words for file-name. 9093 0x74657374 - "test" 9094 0x2e730000 - ".s\0\0" 9095 0x98070001 - lop_line, line 1. 9096 0x00010203 - TRAP 1,2,3 9097 0x980a00ff - lop_post, setting $255 to 0. 9098 0x00000000 9099 0x00000000 9100 0x980b0000 - lop_stab for ":Main" = 0, serial 1. 9101 0x203a4040 *Note Symbol-table::. 9102 0x10404020 9103 0x4d206120 9104 0x69016e00 9105 0x81000000 9106 0x980c0005 - lop_end; symbol table contained five 32-bit words. 9107 9108 9109 File: bfd.info, Node: Symbol-table, Next: mmo section mapping, Prev: File layout, Up: mmo 9110 9111 3.5.2 Symbol table format 9112 ------------------------- 9113 9114 From mmixal.w (or really, the generated mmixal.tex) in 9115 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'): 9116 "Symbols are stored and retrieved by means of a `ternary search trie', 9117 following ideas of Bentley and Sedgewick. (See ACM-SIAM Symp. on 9118 Discrete Algorithms `8' (1997), 360-369; R.Sedgewick, `Algorithms in C' 9119 (Reading, Mass. Addison-Wesley, 1998), `15.4'.) Each trie node stores 9120 a character, and there are branches to subtries for the cases where a 9121 given character is less than, equal to, or greater than the character 9122 in the trie. There also is a pointer to a symbol table entry if a 9123 symbol ends at the current node." 9124 9125 So it's a tree encoded as a stream of bytes. The stream of bytes 9126 acts on a single virtual global symbol, adding and removing characters 9127 and signalling complete symbol points. Here, we read the stream and 9128 create symbols at the completion points. 9129 9130 First, there's a control byte `m'. If any of the listed bits in `m' 9131 is nonzero, we execute what stands at the right, in the listed order: 9132 9133 (MMO3_LEFT) 9134 0x40 - Traverse left trie. 9135 (Read a new command byte and recurse.) 9136 9137 (MMO3_SYMBITS) 9138 0x2f - Read the next byte as a character and store it in the 9139 current character position; increment character position. 9140 Test the bits of `m': 9141 9142 (MMO3_WCHAR) 9143 0x80 - The character is 16-bit (so read another byte, 9144 merge into current character. 9145 9146 (MMO3_TYPEBITS) 9147 0xf - We have a complete symbol; parse the type, value 9148 and serial number and do what should be done 9149 with a symbol. The type and length information 9150 is in j = (m & 0xf). 9151 9152 (MMO3_REGQUAL_BITS) 9153 j == 0xf: A register variable. The following 9154 byte tells which register. 9155 j <= 8: An absolute symbol. Read j bytes as the 9156 big-endian number the symbol equals. 9157 A j = 2 with two zero bytes denotes an 9158 unknown symbol. 9159 j > 8: As with j <= 8, but add (0x20 << 56) 9160 to the value in the following j - 8 9161 bytes. 9162 9163 Then comes the serial number, as a variant of 9164 uleb128, but better named ubeb128: 9165 Read bytes and shift the previous value left 7 9166 (multiply by 128). Add in the new byte, repeat 9167 until a byte has bit 7 set. The serial number 9168 is the computed value minus 128. 9169 9170 (MMO3_MIDDLE) 9171 0x20 - Traverse middle trie. (Read a new command byte 9172 and recurse.) Decrement character position. 9173 9174 (MMO3_RIGHT) 9175 0x10 - Traverse right trie. (Read a new command byte and 9176 recurse.) 9177 9178 Let's look again at the `lop_stab' for the trivial file (*note File 9179 layout::). 9180 9181 0x980b0000 - lop_stab for ":Main" = 0, serial 1. 9182 0x203a4040 9183 0x10404020 9184 0x4d206120 9185 0x69016e00 9186 0x81000000 9187 9188 This forms the trivial trie (note that the path between ":" and "M" 9189 is redundant): 9190 9191 203a ":" 9192 40 / 9193 40 / 9194 10 \ 9195 40 / 9196 40 / 9197 204d "M" 9198 2061 "a" 9199 2069 "i" 9200 016e "n" is the last character in a full symbol, and 9201 with a value represented in one byte. 9202 00 The value is 0. 9203 81 The serial number is 1. 9204 9205 9206 File: bfd.info, Node: mmo section mapping, Prev: Symbol-table, Up: mmo 9207 9208 3.5.3 mmo section mapping 9209 ------------------------- 9210 9211 The implementation in BFD uses special data type 80 (decimal) to 9212 encapsulate and describe named sections, containing e.g. debug 9213 information. If needed, any datum in the encapsulation will be quoted 9214 using lop_quote. First comes a 32-bit word holding the number of 9215 32-bit words containing the zero-terminated zero-padded segment name. 9216 After the name there's a 32-bit word holding flags describing the 9217 section type. Then comes a 64-bit big-endian word with the section 9218 length (in bytes), then another with the section start address. 9219 Depending on the type of section, the contents might follow, 9220 zero-padded to 32-bit boundary. For a loadable section (such as data 9221 or code), the contents might follow at some later point, not 9222 necessarily immediately, as a lop_loc with the same start address as in 9223 the section description, followed by the contents. This in effect 9224 forms a descriptor that must be emitted before the actual contents. 9225 Sections described this way must not overlap. 9226 9227 For areas that don't have such descriptors, synthetic sections are 9228 formed by BFD. Consecutive contents in the two memory areas 9229 `0x0000...00' to `0x01ff...ff' and `0x2000...00' to `0x20ff...ff' are 9230 entered in sections named `.text' and `.data' respectively. If an area 9231 is not otherwise described, but would together with a neighboring lower 9232 area be less than `0x40000000' bytes long, it is joined with the lower 9233 area and the gap is zero-filled. For other cases, a new section is 9234 formed, named `.MMIX.sec.N'. Here, N is a number, a running count 9235 through the mmo file, starting at 0. 9236 9237 A loadable section specified as: 9238 9239 .section secname,"ax" 9240 TETRA 1,2,3,4,-1,-2009 9241 BYTE 80 9242 9243 and linked to address `0x4', is represented by the sequence: 9244 9245 0x98080050 - lop_spec 80 9246 0x00000002 - two 32-bit words for the section name 9247 0x7365636e - "secn" 9248 0x616d6500 - "ame\0" 9249 0x00000033 - flags CODE, READONLY, LOAD, ALLOC 9250 0x00000000 - high 32 bits of section length 9251 0x0000001c - section length is 28 bytes; 6 * 4 + 1 + alignment to 32 bits 9252 0x00000000 - high 32 bits of section address 9253 0x00000004 - section address is 4 9254 0x98010002 - 64 bits with address of following data 9255 0x00000000 - high 32 bits of address 9256 0x00000004 - low 32 bits: data starts at address 4 9257 0x00000001 - 1 9258 0x00000002 - 2 9259 0x00000003 - 3 9260 0x00000004 - 4 9261 0xffffffff - -1 9262 0xfffff827 - -2009 9263 0x50000000 - 80 as a byte, padded with zeros. 9264 9265 Note that the lop_spec wrapping does not include the section 9266 contents. Compare this to a non-loaded section specified as: 9267 9268 .section thirdsec 9269 TETRA 200001,100002 9270 BYTE 38,40 9271 9272 This, when linked to address `0x200000000000001c', is represented by: 9273 9274 0x98080050 - lop_spec 80 9275 0x00000002 - two 32-bit words for the section name 9276 0x7365636e - "thir" 9277 0x616d6500 - "dsec" 9278 0x00000010 - flag READONLY 9279 0x00000000 - high 32 bits of section length 9280 0x0000000c - section length is 12 bytes; 2 * 4 + 2 + alignment to 32 bits 9281 0x20000000 - high 32 bits of address 9282 0x0000001c - low 32 bits of address 0x200000000000001c 9283 0x00030d41 - 200001 9284 0x000186a2 - 100002 9285 0x26280000 - 38, 40 as bytes, padded with zeros 9286 9287 For the latter example, the section contents must not be loaded in 9288 memory, and is therefore specified as part of the special data.

PREAMBLE 9304 9305 The purpose of this License is to make a manual, textbook, or other 9306 functional and useful document "free" in the sense of freedom: to 9307 assure everyone the effective freedom to copy and redistribute it, 9308 with or without modifying it, either commercially or 9309 noncommercially. Secondarily, this License preserves for the 9310 author and publisher a way to get credit for their work, while not 9311 being considered responsible for modifications made by others. 9312 9313 This License is a kind of "copyleft", which means that derivative 9314 works of the document must themselves be free in the same sense. 9315 It complements the GNU General Public License, which is a copyleft 9316 license designed for free software. 9317 9318 We have designed this License in order to use it for manuals for 9319 free software, because free software needs free documentation: a 9320 free program should come with manuals providing the same freedoms 9321 that the software does. But this License is not limited to 9322 software manuals; it can be used for any textual work, regardless 9323 of subject matter or whether it is published as a printed book. 9324 We recommend this License principally for works whose purpose is 9325 instruction or reference. 9326 9327 1. APPLICABILITY AND DEFINITIONS 9328 9329 This License applies to any manual or other work, in any medium, 9330 that contains a notice placed by the copyright holder saying it 9331 can be distributed under the terms of this License. Such a notice 9332 grants a world-wide, royalty-free license, unlimited in duration, 9333 to use that work under the conditions stated herein. The 9334 "Document", below, refers to any such manual or work. Any member 9335 of the public is a licensee, and is addressed as "you". You 9336 accept the license if you copy, modify or distribute the work in a 9337 way requiring permission under copyright law. 9338 9339 A "Modified Version" of the Document means any work containing the 9340 Document or a portion of it, either copied verbatim, or with 9341 modifications and/or translated into another language. 9342 9343 A "Secondary Section" is a named appendix or a front-matter section 9344 of the Document that deals exclusively with the relationship of the 9345 publishers or authors of the Document to the Document's overall 9346 subject (or to related matters) and contains nothing that could 9347 fall directly within that overall subject. (Thus, if the Document 9348 is in part a textbook of mathematics, a Secondary Section may not 9349 explain any mathematics.) The relationship could be a matter of 9350 historical connection with the subject or with related matters, or 9351 of legal, commercial, philosophical, ethical or political position 9352 regarding them. 9353 9354 The "Invariant Sections" are certain Secondary Sections whose 9355 titles are designated, as being those of Invariant Sections, in 9356 the notice that says that the Document is released under this 9357 License. If a section does not fit the above definition of 9358 Secondary then it is not allowed to be designated as Invariant. 9359 The Document may contain zero Invariant Sections. If the Document 9360 does not identify any Invariant Sections then there are none. 9361 9362 The "Cover Texts" are certain short passages of text that are 9363 listed, as Front-Cover Texts or Back-Cover Texts, in the notice 9364 that says that the Document is released under this License. A 9365 Front-Cover Text may be at most 5 words, and a Back-Cover Text may 9366 be at most 25 words. 9367 9368 A "Transparent" copy of the Document means a machine-readable copy, 9369 represented in a format whose specification is available to the 9370 general public, that is suitable for revising the document 9371 straightforwardly with generic text editors or (for images 9372 composed of pixels) generic paint programs or (for drawings) some 9373 widely available drawing editor, and that is suitable for input to 9374 text formatters or for automatic translation to a variety of 9375 formats suitable for input to text formatters. A copy made in an 9376 otherwise Transparent file format whose markup, or absence of 9377 markup, has been arranged to thwart or discourage subsequent 9378 modification by readers is not Transparent. An image format is 9379 not Transparent if used for any substantial amount of text. A 9380 copy that is not "Transparent" is called "Opaque". 9381 9382 Examples of suitable formats for Transparent copies include plain 9383 ASCII without markup, Texinfo input format, LaTeX input format, 9384 SGML or XML using a publicly available DTD, and 9385 standard-conforming simple HTML, PostScript or PDF designed for 9386 human modification. Examples of transparent image formats include 9387 PNG, XCF and JPG. Opaque formats include proprietary formats that 9388 can be read and edited only by proprietary word processors, SGML or 9389 XML for which the DTD and/or processing tools are not generally 9390 available, and the machine-generated HTML, PostScript or PDF 9391 produced by some word processors for output purposes only. 9392 9393 The "Title Page" means, for a printed book, the title page itself, 9394 plus such following pages as are needed to hold, legibly, the 9395 material this License requires to appear in the title page. For 9396 works in formats which do not have any title page as such, "Title 9397 Page" means the text near the most prominent appearance of the 9398 work's title, preceding the beginning of the body of the text. 9399 9400 The "publisher" means any person or entity that distributes copies 9401 of the Document to the public. 9402 9403 A section "Entitled XYZ" means a named subunit of the Document 9404 whose title either is precisely XYZ or contains XYZ in parentheses 9405 following text that translates XYZ in another language. (Here XYZ 9406 stands for a specific section name mentioned below, such as 9407 "Acknowledgements", "Dedications", "Endorsements", or "History".) 9408 To "Preserve the Title" of such a section when you modify the 9409 Document means that it remains a section "Entitled XYZ" according 9410 to this definition. 9411 9412 The Document may include Warranty Disclaimers next to the notice 9413 which states that this License applies to the Document. These 9414 Warranty Disclaimers are considered to be included by reference in 9415 this License, but only as regards disclaiming warranties: any other 9416 implication that these Warranty Disclaimers may have is void and 9417 has no effect on the meaning of this License. 9418 9419 2. VERBATIM COPYING 9420 9421 You may copy and distribute the Document in any medium, either 9422 commercially or noncommercially, provided that this License, the 9423 copyright notices, and the license notice saying this License 9424 applies to the Document are reproduced in all copies, and that you 9425 add no other conditions whatsoever to those of this License. You 9426 may not use technical measures to obstruct or control the reading 9427 or further copying of the copies you make or distribute. However, 9428 you may accept compensation in exchange for copies. If you 9429 distribute a large enough number of copies you must also follow 9430 the conditions in section 3. 9431 9432 You may also lend copies, under the same conditions stated above, 9433 and you may publicly display copies. 9434 9435 3. COPYING IN QUANTITY 9436 9437 If you publish printed copies (or copies in media that commonly 9438 have printed covers) of the Document, numbering more than 100, and 9439 the Document's license notice requires Cover Texts, you must 9440 enclose the copies in covers that carry, clearly and legibly, all 9441 these Cover Texts: Front-Cover Texts on the front cover, and 9442 Back-Cover Texts on the back cover. Both covers must also clearly 9443 and legibly identify you as the publisher of these copies. The 9444 front cover must present the full title with all words of the 9445 title equally prominent and visible. You may add other material 9446 on the covers in addition. Copying with changes limited to the 9447 covers, as long as they preserve the title of the Document and 9448 satisfy these conditions, can be treated as verbatim copying in 9449 other respects. 9450 9451 If the required texts for either cover are too voluminous to fit 9452 legibly, you should put the first ones listed (as many as fit 9453 reasonably) on the actual cover, and continue the rest onto 9454 adjacent pages. 9455 9456 If you publish or distribute Opaque copies of the Document 9457 numbering more than 100, you must either include a 9458 machine-readable Transparent copy along with each Opaque copy, or 9459 state in or with each Opaque copy a computer-network location from 9460 which the general network-using public has access to download 9461 using public-standard network protocols a complete Transparent 9462 copy of the Document, free of added material. If you use the 9463 latter option, you must take reasonably prudent steps, when you 9464 begin distribution of Opaque copies in quantity, to ensure that 9465 this Transparent copy will remain thus accessible at the stated 9466 location until at least one year after the last time you 9467 distribute an Opaque copy (directly or through your agents or 9468 retailers) of that edition to the public. 9469 9470 It is requested, but not required, that you contact the authors of 9471 the Document well before redistributing any large number of 9472 copies, to give them a chance to provide you with an updated 9473 version of the Document. 9474 9475 4. MODIFICATIONS 9476 9477 You may copy and distribute a Modified Version of the Document 9478 under the conditions of sections 2 and 3 above, provided that you 9479 release the Modified Version under precisely this License, with 9480 the Modified Version filling the role of the Document, thus 9481 licensing distribution and modification of the Modified Version to 9482 whoever possesses a copy of it. In addition, you must do these 9483 things in the Modified Version: 9484 9485 A. Use in the Title Page (and on the covers, if any) a title 9486 distinct from that of the Document, and from those of 9487 previous versions (which should, if there were any, be listed 9488 in the History section of the Document). You may use the 9489 same title as a previous version if the original publisher of 9490 that version gives permission. 9491 9492 B. List on the Title Page, as authors, one or more persons or 9493 entities responsible for authorship of the modifications in 9494 the Modified Version, together with at least five of the 9495 principal authors of the Document (all of its principal 9496 authors, if it has fewer than five), unless they release you 9497 from this requirement. 9498 9499 C. State on the Title page the name of the publisher of the 9500 Modified Version, as the publisher. 9501 9502 D. Preserve all the copyright notices of the Document. 9503 9504 E. Add an appropriate copyright notice for your modifications 9505 adjacent to the other copyright notices. 9506 9507 F. Include, immediately after the copyright notices, a license 9508 notice giving the public permission to use the Modified 9509 Version under the terms of this License, in the form shown in 9510 the Addendum below. 9511 9512 G. Preserve in that license notice the full lists of Invariant 9513 Sections and required Cover Texts given in the Document's 9514 license notice. 9515 9516 H. Include an unaltered copy of this License. 9517 9518 I. Preserve the section Entitled "History", Preserve its Title, 9519 and add to it an item stating at least the title, year, new 9520 authors, and publisher of the Modified Version as given on 9521 the Title Page. If there is no section Entitled "History" in 9522 the Document, create one stating the title, year, authors, 9523 and publisher of the Document as given on its Title Page, 9524 then add an item describing the Modified Version as stated in 9525 the previous sentence. 9526 9527 J. Preserve the network location, if any, given in the Document 9528 for public access to a Transparent copy of the Document, and 9529 likewise the network locations given in the Document for 9530 previous versions it was based on. These may be placed in 9531 the "History" section. You may omit a network location for a 9532 work that was published at least four years before the 9533 Document itself, or if the original publisher of the version 9534 it refers to gives permission. 9535 9536 K. For any section Entitled "Acknowledgements" or "Dedications", 9537 Preserve the Title of the section, and preserve in the 9538 section all the substance and tone of each of the contributor 9539 acknowledgements and/or dedications given therein. 9540 9541 L. Preserve all the Invariant Sections of the Document, 9542 unaltered in their text and in their titles. Section numbers 9543 or the equivalent are not considered part of the section 9544 titles. 9545 9546 M. Delete any section Entitled "Endorsements". Such a section 9547 may not be included in the Modified Version. 9548 9549 N. Do not retitle any existing section to be Entitled 9550 "Endorsements" or to conflict in title with any Invariant 9551 Section. 9552 9553 O. Preserve any Warranty Disclaimers. 9554 9555 If the Modified Version includes new front-matter sections or 9556 appendices that qualify as Secondary Sections and contain no 9557 material copied from the Document, you may at your option 9558 designate some or all of these sections as invariant. To do this, 9559 add their titles to the list of Invariant Sections in the Modified 9560 Version's license notice. These titles must be distinct from any 9561 other section titles. 9562 9563 You may add a section Entitled "Endorsements", provided it contains 9564 nothing but endorsements of your Modified Version by various 9565 parties--for example, statements of peer review or that the text 9566 has been approved by an organization as the authoritative 9567 definition of a standard. 9568 9569 You may add a passage of up to five words as a Front-Cover Text, 9570 and a passage of up to 25 words as a Back-Cover Text, to the end 9571 of the list of Cover Texts in the Modified Version. Only one 9572 passage of Front-Cover Text and one of Back-Cover Text may be 9573 added by (or through arrangements made by) any one entity. If the 9574 Document already includes a cover text for the same cover, 9575 previously added by you or by arrangement made by the same entity 9576 you are acting on behalf of, you may not add another; but you may 9577 replace the old one, on explicit permission from the previous 9578 publisher that added the old one. 9579 9580 The author(s) and publisher(s) of the Document do not by this 9581 License give permission to use their names for publicity for or to 9582 assert or imply endorsement of any Modified Version. 9583 9584 5. COMBINING DOCUMENTS 9585 9586 You may combine the Document with other documents released under 9587 this License, under the terms defined in section 4 above for 9588 modified versions, provided that you include in the combination 9589 all of the Invariant Sections of all of the original documents, 9590 unmodified, and list them all as Invariant Sections of your 9591 combined work in its license notice, and that you preserve all 9592 their Warranty Disclaimers. 9593 9594 The combined work need only contain one copy of this License, and 9595 multiple identical Invariant Sections may be replaced with a single 9596 copy. If there are multiple Invariant Sections with the same name 9597 but different contents, make the title of each such section unique 9598 by adding at the end of it, in parentheses, the name of the 9599 original author or publisher of that section if known, or else a 9600 unique number. Make the same adjustment to the section titles in 9601 the list of Invariant Sections in the license notice of the 9602 combined work. 9603 9604 In the combination, you must combine any sections Entitled 9605 "History" in the various original documents, forming one section 9606 Entitled "History"; likewise combine any sections Entitled 9607 "Acknowledgements", and any sections Entitled "Dedications". You 9608 must delete all sections Entitled "Endorsements." 9609 9610 6. COLLECTIONS OF DOCUMENTS 9611 9612 You may make a collection consisting of the Document and other 9613 documents released under this License, and replace the individual 9614 copies of this License in the various documents with a single copy 9615 that is included in the collection, provided that you follow the 9616 rules of this License for verbatim copying of each of the 9617 documents in all other respects. 9618 9619 You may extract a single document from such a collection, and 9620 distribute it individually under this License, provided you insert 9621 a copy of this License into the extracted document, and follow 9622 this License in all other respects regarding verbatim copying of 9623 that document. 9624 9625 7. AGGREGATION WITH INDEPENDENT WORKS 9626 9627 A compilation of the Document or its derivatives with other 9628 separate and independent documents or works, in or on a volume of 9629 a storage or distribution medium, is called an "aggregate" if the 9630 copyright resulting from the compilation is not used to limit the 9631 legal rights of the compilation's users beyond what the individual 9632 works permit. When the Document is included in an aggregate, this 9633 License does not apply to the other works in the aggregate which 9634 are not themselves derivative works of the Document. 9635 9636 If the Cover Text requirement of section 3 is applicable to these 9637 copies of the Document, then if the Document is less than one half 9638 of the entire aggregate, the Document's Cover Texts may be placed 9639 on covers that bracket the Document within the aggregate, or the 9640 electronic equivalent of covers if the Document is in electronic 9641 form. Otherwise they must appear on printed covers that bracket 9642 the whole aggregate. 9643 9644 8. TRANSLATION 9645 9646 Translation is considered a kind of modification, so you may 9647 distribute translations of the Document under the terms of section 9648 4. Replacing Invariant Sections with translations requires special 9649 permission from their copyright holders, but you may include 9650 translations of some or all Invariant Sections in addition to the 9651 original versions of these Invariant Sections. You may include a 9652 translation of this License, and all the license notices in the 9653 Document, and any Warranty Disclaimers, provided that you also 9654 include the original English version of this License and the 9655 original versions of those notices and disclaimers. In case of a 9656 disagreement between the translation and the original version of 9657 this License or a notice or disclaimer, the original version will 9658 prevail. 9659 9660 If a section in the Document is Entitled "Acknowledgements", 9661 "Dedications", or "History", the requirement (section 4) to 9662 Preserve its Title (section 1) will typically require changing the 9663 actual title. 9664 9665 9. TERMINATION 9666 9667 You may not copy, modify, sublicense, or distribute the Document 9668 except as expressly provided under this License. Any attempt 9669 otherwise to copy, modify, sublicense, or distribute it is void, 9670 and will automatically terminate your rights under this License. 9671 9672 However, if you cease all violation of this License, then your 9673 license from a particular copyright holder is reinstated (a) 9674 provisionally, unless and until the copyright holder explicitly 9675 and finally terminates your license, and (b) permanently, if the 9676 copyright holder fails to notify you of the violation by some 9677 reasonable means prior to 60 days after the cessation. 9678 9679 Moreover, your license from a particular copyright holder is 9680 reinstated permanently if the copyright holder notifies you of the 9681 violation by some reasonable means, this is the first time you have 9682 received notice of violation of this License (for any work) from 9683 that copyright holder, and you cure the violation prior to 30 days 9684 after your receipt of the notice. 9685 9686 Termination of your rights under this section does not terminate 9687 the licenses of parties who have received copies or rights from 9688 you under this License. If your rights have been terminated and 9689 not permanently reinstated, receipt of a copy of some or all of 9690 the same material does not give you any rights to use it. 9691 9692 10. FUTURE REVISIONS OF THIS LICENSE 9693 9694 The Free Software Foundation may publish new, revised versions of 9695 the GNU Free Documentation License from time to time. Such new 9696 versions will be similar in spirit to the present version, but may 9697 differ in detail to address new problems or concerns. See 9698 `http://www.gnu.org/copyleft/'. 9699 9700 Each version of the License is given a distinguishing version 9701 number. If the Document specifies that a particular numbered 9702 version of this License "or any later version" applies to it, you 9703 have the option of following the terms and conditions either of 9704 that specified version or of any later version that has been 9705 published (not as a draft) by the Free Software Foundation. If 9706 the Document does not specify a version number of this License, 9707 you may choose any version ever published (not as a draft) by the 9708 Free Software Foundation. If the Document specifies that a proxy 9709 can decide which future versions of this License can be used, that 9710 proxy's public statement of acceptance of a version permanently 9711 authorizes you to choose that version for the Document. 9712 9713 11. RELICENSING 9714 9715 "Massive Multiauthor Collaboration Site" (or "MMC Site") means any 9716 World Wide Web server that publishes copyrightable works and also 9717 provides prominent facilities for anybody to edit those works. A 9718 public wiki that anybody can edit is an example of such a server. 9719 A "Massive Multiauthor Collaboration" (or "MMC") contained in the 9720 site means any set of copyrightable works thus published on the MMC 9721 site. 9722 9723 "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0 9724 license published by Creative Commons Corporation, a not-for-profit 9725 corporation with a principal place of business in San Francisco, 9726 California, as well as future copyleft versions of that license 9727 published by that same organization. 9728 9729 "Incorporate" means to publish or republish a Document, in whole or 9730 in part, as part of another Document. 9731 9732 An MMC is "eligible for relicensing" if it is licensed under this 9733 License, and if all works that were first published under this 9734 License somewhere other than this MMC, and subsequently 9735 incorporated in whole or in part into the MMC, (1) had no cover 9736 texts or invariant sections, and (2) were thus incorporated prior 9737 to November 1, 2008. 9738 9739 The operator of an MMC Site may republish an MMC contained in the 9740 site under CC-BY-SA on the same site at any time before August 1, 9741 2009, provided the MMC is eligible for relicensing. 9742 9743 9744 ADDENDUM: How to use this License for your documents 9745 ==================================================== 9746 9747 To use this License in a document you have written, include a copy of 9748 the License in the document and put the following copyright and license 9749 notices just after the title page: 9750 9751 Copyright (C) YEAR YOUR NAME. 9752 Permission is granted to copy, distribute and/or modify this document 9753 under the terms of the GNU Free Documentation License, Version 1.3 9754 or any later version published by the Free Software Foundation; 9755 with no Invariant Sections, no Front-Cover Texts, and no Back-Cover 9756 Texts. A copy of the license is included in the section entitled ``GNU 9757 Free Documentation License''. 9758 9759 If you have Invariant Sections, Front-Cover Texts and Back-Cover 9760 Texts, replace the "with...Texts." line with this: 9761 9762 with the Invariant Sections being LIST THEIR TITLES, with 9763 the Front-Cover Texts being LIST, and with the Back-Cover Texts 9764 being LIST. 9765 9766 If you have Invariant Sections without Cover Texts, or some other 9767 combination of the three, merge those two alternatives to suit the 9768 situation. 9769 9770 If your document contains nontrivial examples of program code, we 9771 recommend releasing these examples in parallel under your choice of 9772 free software license, such as the GNU General Public License, to 9773 permit their use in free software. 9774 9775 9776 File: bfd.info, Node: BFD Index, Prev: GNU Free Documentation License, Up: Top 9777 9778 BFD Index 9779 ********* 9780 9781 [index] 9782 * Menu: 9783 9784 * _bfd_final_link_relocate: Relocating the section contents. 9785 (line 22) 9786 * _bfd_generic_link_add_archive_symbols: Adding symbols from an archive. 9787 (line 12) 9788 * _bfd_generic_link_add_one_symbol: Adding symbols from an object file. 9789 (line 19) 9790 * _bfd_generic_make_empty_symbol: symbol handling functions. 9791 (line 92) 9792 * _bfd_link_add_symbols in target vector: Adding Symbols to the Hash Table. 9793 (line 6) 9794 * _bfd_link_final_link in target vector: Performing the Final Link. 9795 (line 6) 9796 * _bfd_link_hash_table_create in target vector: Creating a Linker Hash Table. 9797 (line 6) 9798 * _bfd_relocate_contents: Relocating the section contents. 9799 (line 22) 9800 * aout_SIZE_machine_type: aout.
