A new object 41 file format can be supported simply by creating a new BFD back end and 42 adding it to the library. 43 44 BFD is split into two parts: the front end, and the back ends (one 45 for each object file format). 46 * The front end of BFD provides the interface to the user. It manages 47 memory and various canonical data structures. The front end also 48 decides which back end to use and when to call back end routines. 49 50 * The back ends provide BFD its view of the real world. Each back 51 end provides a set of calls which the BFD front end can use to 52 maintain its canonical form. The back ends also may keep around 53 information for their own use, for greater efficiency. 54 55 * Menu: 56 57 * History:: History 58 * How It Works:: How It Works 59 * What BFD Version 2 Can Do:: What BFD Version 2 Can Do 60 61 62 File: bfd.info, Node: History, Next: How It Works, Prev: Overview, Up: Overview 63 64 1.1 History 65 =========== 66 67 One spur behind BFD was the desire, on the part of the GNU 960 team at 68 Intel Oregon, for interoperability of applications on their COFF and 69 b.out file formats. Cygnus was providing GNU support for the team, and 70 was contracted to provide the required functionality. 71 72 The name came from a conversation David Wallace was having with 73 Richard Stallman about the library: RMS said that it would be quite 74 hard--David said "BFD". Stallman was right, but the name stuck. 75 76 At the same time, Ready Systems wanted much the same thing, but for 77 different object file formats: IEEE-695, Oasys, Srecords, a.out and 68k 78 coff. 79 80 BFD was first implemented by members of Cygnus Support; Steve 81 Chamberlain (`sac (a] cygnus.com'), John Gilmore (`gnu (a] cygnus.com'), K. 82 Richard Pixley (`rich (a] cygnus.com') and David Henkel-Wallace 83 (`gumby (a] cygnus.com'). 84 85 86 File: bfd.info, Node: How It Works, Next: What BFD Version 2 Can Do, Prev: History, Up: Overview 87 88 1.2 How To Use BFD 89 ================== 90 91 To use the library, include `bfd.h' and link with `libbfd.a'. 92 93 BFD provides a common interface to the parts of an object file for a 94 calling application. 95 96 When an application successfully opens a target file (object, 97 archive, or whatever), a pointer to an internal structure is returned. 98 This pointer points to a structure called `bfd', described in `bfd.h'. 99 Our convention is to call this pointer a BFD, and instances of it 100 within code `abfd'. All operations on the target object file are 101 applied as methods to the BFD. The mapping is defined within `bfd.h' 102 in a set of macros, all beginning with `bfd_' to reduce namespace 103 pollution. 104 105 For example, this sequence does what you would probably expect: 106 return the number of sections in an object file attached to a BFD 107 `abfd'. 108 109 #include "bfd.h" 110 111 unsigned int number_of_sections (abfd) 112 bfd *abfd; 113 { 114 return bfd_count_sections (abfd); 115 } 116 117 The abstraction used within BFD is that an object file has: 118 119 * a header, 120 121 * a number of sections containing raw data (*note Sections::), 122 123 * a set of relocations (*note Relocations::), and 124 125 * some symbol information (*note Symbols::). 126 Also, BFDs opened for archives have the additional attribute of an 127 index and contain subordinate BFDs. This approach is fine for a.out and 128 coff, but loses efficiency when applied to formats such as S-records and 129 IEEE-695. 130 131 132 File: bfd.info, Node: What BFD Version 2 Can Do, Prev: How It Works, Up: Overview 133 134 1.3 What BFD Version 2 Can Do 135 ============================= 136 137 When an object file is opened, BFD subroutines automatically determine 138 the format of the input object file. They then build a descriptor in 139 memory with pointers to routines that will be used to access elements of 140 the object file's data structures. 141 142 As different information from the object files is required, BFD 143 reads from different sections of the file and processes them. For 144 example, a very common operation for the linker is processing symbol 145 tables. Each BFD back end provides a routine for converting between 146 the object file's representation of symbols and an internal canonical 147 format. When the linker asks for the symbol table of an object file, it 148 calls through a memory pointer to the routine from the relevant BFD 149 back end which reads and converts the table into a canonical form. The 150 linker then operates upon the canonical form. When the link is finished 151 and the linker writes the output file's symbol table, another BFD back 152 end routine is called to take the newly created symbol table and 153 convert it into the chosen output format. 154 155 * Menu: 156 157 * BFD information loss:: Information Loss 158 * Canonical format:: The BFD canonical object-file format 159 160 161 File: bfd.info, Node: BFD information loss, Next: Canonical format, Up: What BFD Version 2 Can Do 162 163 1.3.1 Information Loss 164 ---------------------- 165 166 _Information can be lost during output._ The output formats supported 167 by BFD do not provide identical facilities, and information which can 168 be described in one form has nowhere to go in another format. One 169 example of this is alignment information in `b.out'. There is nowhere 170 in an `a.out' format file to store alignment information on the 171 contained data, so when a file is linked from `b.out' and an `a.out' 172 image is produced, alignment information will not propagate to the 173 output file. (The linker will still use the alignment information 174 internally, so the link is performed correctly). 175 176 Another example is COFF section names. COFF files may contain an 177 unlimited number of sections, each one with a textual section name. If 178 the target of the link is a format which does not have many sections 179 (e.g., `a.out') or has sections without names (e.g., the Oasys format), 180 the link cannot be done simply. You can circumvent this problem by 181 describing the desired input-to-output section mapping with the linker 182 command language. 183 184 _Information can be lost during canonicalization._ The BFD internal 185 canonical form of the external formats is not exhaustive; there are 186 structures in input formats for which there is no direct representation 187 internally. This means that the BFD back ends cannot maintain all 188 possible data richness through the transformation between external to 189 internal and back to external formats. 190 191 This limitation is only a problem when an application reads one 192 format and writes another. Each BFD back end is responsible for 193 maintaining as much data as possible, and the internal BFD canonical 194 form has structures which are opaque to the BFD core, and exported only 195 to the back ends. When a file is read in one format, the canonical form 196 is generated for BFD and the application. At the same time, the back 197 end saves away any information which may otherwise be lost. If the data 198 is then written back in the same format, the back end routine will be 199 able to use the canonical form provided by the BFD core as well as the 200 information it prepared earlier. Since there is a great deal of 201 commonality between back ends, there is no information lost when 202 linking or copying big endian COFF to little endian COFF, or `a.out' to 203 `b.out'. When a mixture of formats is linked, the information is only 204 lost from the files whose format differs from the destination. 205 206 207 File: bfd.info, Node: Canonical format, Prev: BFD information loss, Up: What BFD Version 2 Can Do 208 209 1.3.2 The BFD canonical object-file format 210 ------------------------------------------ 211 212 The greatest potential for loss of information occurs when there is the 213 least overlap between the information provided by the source format, 214 that stored by the canonical format, and that needed by the destination 215 format. A brief description of the canonical form may help you 216 understand which kinds of data you can count on preserving across 217 conversions. 218 219 _files_ 220 Information stored on a per-file basis includes target machine 221 architecture, particular implementation format type, a demand 222 pageable bit, and a write protected bit. Information like Unix 223 magic numbers is not stored here--only the magic numbers' meaning, 224 so a `ZMAGIC' file would have both the demand pageable bit and the 225 write protected text bit set. The byte order of the target is 226 stored on a per-file basis, so that big- and little-endian object 227 files may be used with one another. 228 229 _sections_ 230 Each section in the input file contains the name of the section, 231 the section's original address in the object file, size and 232 alignment information, various flags, and pointers into other BFD 233 data structures. 234 235 _symbols_ 236 Each symbol contains a pointer to the information for the object 237 file which originally defined it, its name, its value, and various 238 flag bits. When a BFD back end reads in a symbol table, it 239 relocates all symbols to make them relative to the base of the 240 section where they were defined. Doing this ensures that each 241 symbol points to its containing section. Each symbol also has a 242 varying amount of hidden private data for the BFD back end. Since 243 the symbol points to the original file, the private data format 244 for that symbol is accessible. `ld' can operate on a collection 245 of symbols of wildly different formats without problems. 246 247 Normal global and simple local symbols are maintained on output, 248 so an output file (no matter its format) will retain symbols 249 pointing to functions and to global, static, and common variables. 250 Some symbol information is not worth retaining; in `a.out', type 251 information is stored in the symbol table as long symbol names. 252 This information would be useless to most COFF debuggers; the 253 linker has command line switches to allow users to throw it away. 254 255 There is one word of type information within the symbol, so if the 256 format supports symbol type information within symbols (for 257 example, COFF, IEEE, Oasys) and the type is simple enough to fit 258 within one word (nearly everything but aggregates), the 259 information will be preserved. 260 261 _relocation level_ 262 Each canonical BFD relocation record contains a pointer to the 263 symbol to relocate to, the offset of the data to relocate, the 264 section the data is in, and a pointer to a relocation type 265 descriptor. Relocation is performed by passing messages through 266 the relocation type descriptor and the symbol pointer. Therefore, 267 relocations can be performed on output data using a relocation 268 method that is only available in one of the input formats. For 269 instance, Oasys provides a byte relocation format. A relocation 270 record requesting this relocation type would point indirectly to a 271 routine to perform this, so the relocation may be performed on a 272 byte being written to a 68k COFF file, even though 68k COFF has no 273 such relocation type. 274 275 _line numbers_ 276 Object formats can contain, for debugging purposes, some form of 277 mapping between symbols, source line numbers, and addresses in the 278 output file. These addresses have to be relocated along with the 279 symbol information. Each symbol with an associated list of line 280 number records points to the first record of the list. The head 281 of a line number list consists of a pointer to the symbol, which 282 allows finding out the address of the function whose line number 283 is being described. The rest of the list is made up of pairs: 284 offsets into the section and line numbers. Any format which can 285 simply derive this information can pass it successfully between 286 formats (COFF, IEEE and Oasys). 287 288 289 File: bfd.info, Node: BFD front end, Next: BFD back ends, Prev: Overview, Up: Top 290 291 2 BFD Front End 292 *************** 293 294 2.1 `typedef bfd' 295 ================= 296 297 A BFD has type `bfd'; objects of this type are the cornerstone of any 298 application using BFD.

If that returns `bfd_error_system_call', then 478 check `errno'. 479 480 The easiest way to report a BFD error to the user is to use 481 `bfd_perror'. 482 483 2.2.1 Type `bfd_error_type' 484 --------------------------- 485 486 The values returned by `bfd_get_error' are defined by the enumerated 487 type `bfd_error_type'. 488 489 490 typedef enum bfd_error 491 { 492 bfd_error_no_error = 0, 493 bfd_error_system_call, 494 bfd_error_invalid_target, 495 bfd_error_wrong_format, 496 bfd_error_wrong_object_format, 497 bfd_error_invalid_operation, 498 bfd_error_no_memory, 499 bfd_error_no_symbols, 500 bfd_error_no_armap, 501 bfd_error_no_more_archived_files, 502 bfd_error_malformed_archive, 503 bfd_error_file_not_recognized, 504 bfd_error_file_ambiguously_recognized, 505 bfd_error_no_contents, 506 bfd_error_nonrepresentable_section, 507 bfd_error_no_debug_section, 508 bfd_error_bad_value, 509 bfd_error_file_truncated, 510 bfd_error_file_too_big, 511 bfd_error_on_input, 512 bfd_error_invalid_error_code 513 } 514 bfd_error_type; 515 516 2.2.1.1 `bfd_get_error' 517 ....................... 518 519 *Synopsis* 520 bfd_error_type bfd_get_error (void); 521 *Description* 522 Return the current BFD error condition. 523 524 2.2.1.2 `bfd_set_error' 525 ....................... 526 527 *Synopsis* 528 void bfd_set_error (bfd_error_type error_tag, ...); 529 *Description* 530 Set the BFD error condition to be ERROR_TAG.

(Though without as many bells and 722 whistles as `strtoul'.) The expression is assumed to be unsigned 723 (i.e., positive). If given a BASE, it is used as the base for 724 conversion. A base of 0 causes the function to interpret the string in 725 hex if a leading "0x" or "0X" is found, otherwise in octal if a leading 726 zero is found, otherwise in decimal. 727 728 If the value would overflow, the maximum `bfd_vma' value is returned. 729 730 2.3.1.11 `bfd_copy_private_header_data' 731 ....................................... 732 733 *Synopsis* 734 bfd_boolean bfd_copy_private_header_data (bfd *ibfd, bfd *obfd); 735 *Description* 736 Copy private BFD header information from the BFD IBFD to the the BFD 737 OBFD.

It 1039 would be ideal if someone could eventually modify it so that such 1040 results were guaranteed. 1041 1042 Instead, we want to ask questions like "is this NNN byte sized 1043 object I'm about to try read from file offset YYY reasonable?" As as 1044 example of where we might do this, some object formats use string 1045 tables for which the first `sizeof (long)' bytes of the table contain 1046 the size of the table itself, including the size bytes. If an 1047 application tries to read what it thinks is one of these string tables, 1048 without some way to validate the size, and for some reason the size is 1049 wrong (byte swapping error, wrong location for the string table, etc.), 1050 the only clue is likely to be a read error when it tries to read the 1051 table, or a "virtual memory exhausted" error when it tries to allocate 1052 15 bazillon bytes of space for the 15 bazillon byte table it is about 1053 to read. This function at least allows us to answer the question, "is 1054 the size reasonable?". 1055 1056 * Menu: 1057 1058 * Memory Usage:: 1059 * Initialization:: 1060 * Sections:: 1061 * Symbols:: 1062 * Archives:: 1063 * Formats:: 1064 * Relocations:: 1065 * Core Files:: 1066 * Targets:: 1067 * Architectures:: 1068 * Opening and Closing:: 1069 * Internal:: 1070 * File Caching:: 1071 * Linker Functions:: 1072 * Hash Tables:: 1073 1074 1075 File: bfd.info, Node: Memory Usage, Next: Initialization, Prev: BFD front end, Up: BFD front end 1076 1077 2.4 Memory Usage 1078 ================ 1079 1080 BFD keeps all of its internal structures in obstacks. There is one 1081 obstack per open BFD file, into which the current state is stored. When 1082 a BFD is closed, the obstack is deleted, and so everything which has 1083 been allocated by BFD for the closing file is thrown away. 1084 1085 BFD does not free anything created by an application, but pointers 1086 into `bfd' structures become invalid on a `bfd_close'; for example, 1087 after a `bfd_close' the vector passed to `bfd_canonicalize_symtab' is 1088 still around, since it has been allocated by the application, but the 1089 data that it pointed to are lost. 1090 1091 The general rule is to not close a BFD until all operations dependent 1092 upon data from the BFD have been completed, or all the data from within 1093 the file has been copied. To help with the management of memory, there 1094 is a function (`bfd_alloc_size') which returns the number of bytes in 1095 obstacks associated with the supplied BFD. This could be used to select 1096 the greediest open BFD, close it to reclaim the memory, perform some 1097 operation and reopen the BFD again, to get a fresh copy of the data 1098 structures. 1099 1100 1101 File: bfd.info, Node: Initialization, Next: Sections, Prev: Memory Usage, Up: BFD front end 1102 1103 2.5 Initialization 1104 ================== 1105 1106 2.5.1 Initialization functions 1107 ------------------------------ 1108 1109 These are the functions that handle initializing a BFD. 1110 1111 2.5.1.1 `bfd_init' 1112 .................. 1113 1114 *Synopsis* 1115 void bfd_init (void); 1116 *Description* 1117 This routine must be called before any other BFD function to initialize 1118 magical internal data structures. 1119 1120 1121 File: bfd.info, Node: Sections, Next: Symbols, Prev: Initialization, Up: BFD front end 1122 1123 2.6 Sections 1124 ============ 1125 1126 The raw data contained within a BFD is maintained through the section 1127 abstraction. A single BFD may have any number of sections. It keeps 1128 hold of them by pointing to the first; each one points to the next in 1129 the list. 1130 1131 Sections are supported in BFD in `section.c'. 1132 1133 * Menu: 1134 1135 * Section Input:: 1136 * Section Output:: 1137 * typedef asection:: 1138 * section prototypes:: 1139 1140 1141 File: bfd.info, Node: Section Input, Next: Section Output, Prev: Sections, Up: Sections 1142 1143 2.6.1 Section input 1144 ------------------- 1145 1146 When a BFD is opened for reading, the section structures are created 1147 and attached to the BFD. 1148 1149 Each section has a name which describes the section in the outside 1150 world--for example, `a.out' would contain at least three sections, 1151 called `.text', `.data' and `.bss'. 1152 1153 Names need not be unique; for example a COFF file may have several 1154 sections named `.data'. 1155 1156 Sometimes a BFD will contain more than the "natural" number of 1157 sections. A back end may attach other sections containing constructor 1158 data, or an application may add a section (using `bfd_make_section') to 1159 the sections attached to an already open BFD. For example, the linker 1160 creates an extra section `COMMON' for each input file's BFD to hold 1161 information about common storage. 1162 1163 The raw data is not necessarily read in when the section descriptor 1164 is created. Some targets may leave the data in place until a 1165 `bfd_get_section_contents' call is made. Other back ends may read in 1166 all the data at once. For example, an S-record file has to be read 1167 once to determine the size of the data. An IEEE-695 file doesn't 1168 contain raw data in sections, but data and relocation expressions 1169 intermixed, so the data area has to be parsed to get out the data and 1170 relocations. 1171 1172 1173 File: bfd.info, Node: Section Output, Next: typedef asection, Prev: Section Input, Up: Sections 1174 1175 2.6.2 Section output 1176 -------------------- 1177 1178 To write a new object style BFD, the various sections to be written 1179 have to be created. They are attached to the BFD in the same way as 1180 input sections; data is written to the sections using 1181 `bfd_set_section_contents'. 1182 1183 Any program that creates or combines sections (e.g., the assembler 1184 and linker) must use the `asection' fields `output_section' and 1185 `output_offset' to indicate the file sections to which each section 1186 must be written. (If the section is being created from scratch, 1187 `output_section' should probably point to the section itself and 1188 `output_offset' should probably be zero.) 1189 1190 The data to be written comes from input sections attached (via 1191 `output_section' pointers) to the output sections. The output section 1192 structure can be considered a filter for the input section: the output 1193 section determines the vma of the output data and the name, but the 1194 input section determines the offset into the output section of the data 1195 to be written. 1196 1197 E.g., to create a section "O", starting at 0x100, 0x123 long, 1198 containing two subsections, "A" at offset 0x0 (i.e., at vma 0x100) and 1199 "B" at offset 0x20 (i.e., at vma 0x120) the `asection' structures would 1200 look like: 1201 1202 section name "A" 1203 output_offset 0x00 1204 size 0x20 1205 output_section -----------> section name "O" 1206 | vma 0x100 1207 section name "B" | size 0x123 1208 output_offset 0x20 | 1209 size 0x103 | 1210 output_section --------| 1211 1212 2.6.3 Link orders 1213 ----------------- 1214 1215 The data within a section is stored in a "link_order". These are much 1216 like the fixups in `gas'. The link_order abstraction allows a section 1217 to grow and shrink within itself. 1218 1219 A link_order knows how big it is, and which is the next link_order 1220 and where the raw data for it is; it also points to a list of 1221 relocations which apply to it. 1222 1223 The link_order is used by the linker to perform relaxing on final 1224 code. The compiler creates code which is as big as necessary to make 1225 it work without relaxing, and the user can select whether to relax. 1226 Sometimes relaxing takes a lot of time. The linker runs around the 1227 relocations to see if any are attached to data which can be shrunk, if 1228 so it does it on a link_order by link_order basis. 1229 1230 1231 File: bfd.info, Node: typedef asection, Next: section prototypes, Prev: Section Output, Up: Sections 1232 1233 2.6.4 typedef asection 1234 ---------------------- 1235 1236 Here is the section structure: 1237 1238 1239 typedef struct bfd_section 1240 { 1241 /* The name of the section; the name isn't a copy, the pointer is 1242 the same as that passed to bfd_make_section. */ 1243 const char *name; 1244 1245 /* A unique sequence number. */ 1246 int id; 1247 1248 /* Which section in the bfd; 0..n-1 as sections are created in a bfd. */ 1249 int index; 1250 1251 /* The next section in the list belonging to the BFD, or NULL. */ 1252 struct bfd_section *next; 1253 1254 /* The previous section in the list belonging to the BFD, or NULL. */ 1255 struct bfd_section *prev; 1256 1257 /* The field flags contains attributes of the section.

BFD passes information to 2057 applications though the `asymbol' structure. When the application 2058 requests the symbol table, BFD reads the table in the native form and 2059 translates parts of it into the internal format. To maintain more than 2060 the information passed to applications, some targets keep some 2061 information "behind the scenes" in a structure only the particular back 2062 end knows about. For example, the coff back end keeps the original 2063 symbol table structure as well as the canonical structure when a BFD is 2064 read in. On output, the coff back end can reconstruct the output symbol 2065 table so that no information is lost, even information unique to coff 2066 which BFD doesn't know or understand. If a coff symbol table were read, 2067 but were written through an a.out back end, all the coff specific 2068 information would be lost. The symbol table of a BFD is not necessarily 2069 read in until a canonicalize request is made. Then the BFD back end 2070 fills in a table provided by the application with pointers to the 2071 canonical information. To output symbols, the application provides BFD 2072 with a table of pointers to pointers to `asymbol's. This allows 2073 applications like the linker to output a symbol as it was read, since 2074 the "behind the scenes" information will be still available. 2075 2076 * Menu: 2077 2078 * Reading Symbols:: 2079 * Writing Symbols:: 2080 * Mini Symbols:: 2081 * typedef asymbol:: 2082 * symbol handling functions:: 2083 2084 2085 File: bfd.info, Node: Reading Symbols, Next: Writing Symbols, Prev: Symbols, Up: Symbols 2086 2087 2.7.1 Reading symbols 2088 --------------------- 2089 2090 There are two stages to reading a symbol table from a BFD: allocating 2091 storage, and the actual reading process. This is an excerpt from an 2092 application which reads the symbol table: 2093 2094 long storage_needed; 2095 asymbol **symbol_table; 2096 long number_of_symbols; 2097 long i; 2098 2099 storage_needed = bfd_get_symtab_upper_bound (abfd); 2100 2101 if (storage_needed < 0) 2102 FAIL 2103 2104 if (storage_needed == 0) 2105 return; 2106 2107 symbol_table = xmalloc (storage_needed); 2108 ... 2109 number_of_symbols = 2110 bfd_canonicalize_symtab (abfd, symbol_table); 2111 2112 if (number_of_symbols < 0) 2113 FAIL 2114 2115 for (i = 0; i < number_of_symbols; i++) 2116 process_symbol (symbol_table[i]); 2117 2118 All storage for the symbols themselves is in an objalloc connected 2119 to the BFD; it is freed when the BFD is closed. 2120 2121 2122 File: bfd.info, Node: Writing Symbols, Next: Mini Symbols, Prev: Reading Symbols, Up: Symbols 2123 2124 2.7.2 Writing symbols 2125 --------------------- 2126 2127 Writing of a symbol table is automatic when a BFD open for writing is 2128 closed. The application attaches a vector of pointers to pointers to 2129 symbols to the BFD being written, and fills in the symbol count. The 2130 close and cleanup code reads through the table provided and performs 2131 all the necessary operations. The BFD output code must always be 2132 provided with an "owned" symbol: one which has come from another BFD, 2133 or one which has been created using `bfd_make_empty_symbol'. Here is an 2134 example showing the creation of a symbol table with only one element: 2135 2136 #include "bfd.h" 2137 int main (void) 2138 { 2139 bfd *abfd; 2140 asymbol *ptrs[2]; 2141 asymbol *new; 2142 2143 abfd = bfd_openw ("foo","a.out-sunos-big"); 2144 bfd_set_format (abfd, bfd_object); 2145 new = bfd_make_empty_symbol (abfd); 2146 new->name = "dummy_symbol"; 2147 new->section = bfd_make_section_old_way (abfd, ".text"); 2148 new->flags = BSF_GLOBAL; 2149 new->value = 0x12345; 2150 2151 ptrs[0] = new; 2152 ptrs[1] = 0; 2153 2154 bfd_set_symtab (abfd, ptrs, 1); 2155 bfd_close (abfd); 2156 return 0; 2157 } 2158 2159 ./makesym 2160 nm foo 2161 00012345 A dummy_symbol 2162 2163 Many formats cannot represent arbitrary symbol information; for 2164 instance, the `a.out' object format does not allow an arbitrary number 2165 of sections. A symbol pointing to a section which is not one of 2166 `.text', `.data' or `.bss' cannot be described. 2167 2168 2169 File: bfd.info, Node: Mini Symbols, Next: typedef asymbol, Prev: Writing Symbols, Up: Symbols 2170 2171 2.7.3 Mini Symbols 2172 ------------------ 2173 2174 Mini symbols provide read-only access to the symbol table. They use 2175 less memory space, but require more time to access. They can be useful 2176 for tools like nm or objdump, which may have to handle symbol tables of 2177 extremely large executables. 2178 2179 The `bfd_read_minisymbols' function will read the symbols into 2180 memory in an internal form.

It has a symbol table, 2491 although there's not much a user program will do with it. 2492 2493 The big difference between an archive BFD and an ordinary BFD is 2494 that the archive doesn't have sections. Instead it has a chain of BFDs 2495 that are considered its contents. These BFDs can be manipulated like 2496 any other. The BFDs contained in an archive opened for reading will 2497 all be opened for reading. You may put either input or output BFDs 2498 into an archive opened for output; they will be handled correctly when 2499 the archive is closed. 2500 2501 Use `bfd_openr_next_archived_file' to step through the contents of 2502 an archive opened for input. You don't have to read the entire archive 2503 if you don't want to! Read it until you find what you want. 2504 2505 Archive contents of output BFDs are chained through the `next' 2506 pointer in a BFD. The first one is findable through the `archive_head' 2507 slot of the archive. Set it with `bfd_set_archive_head' (q.v.). A 2508 given BFD may be in only one open output archive at a time. 2509 2510 As expected, the BFD archive code is more general than the archive 2511 code of any given environment. BFD archives may contain files of 2512 different formats (e.g., a.out and coff) and even different 2513 architectures. You may even place archives recursively into archives! 2514 2515 This can cause unexpected confusion, since some archive formats are 2516 more expressive than others. For instance, Intel COFF archives can 2517 preserve long filenames; SunOS a.out archives cannot. If you move a 2518 file from the first to the second format and back again, the filename 2519 may be truncated. Likewise, different a.out environments have different 2520 conventions as to how they truncate filenames, whether they preserve 2521 directory names in filenames, etc. When interoperating with native 2522 tools, be sure your files are homogeneous. 2523 2524 Beware: most of these formats do not react well to the presence of 2525 spaces in filenames. We do the best we can, but can't always handle 2526 this case due to restrictions in the format of archives. Many Unix 2527 utilities are braindead in regards to spaces and such in filenames 2528 anyway, so this shouldn't be much of a restriction. 2529 2530 Archives are supported in BFD in `archive.c'. 2531 2532 2.8.1 Archive functions 2533 ----------------------- 2534 2535 2.8.1.1 `bfd_get_next_mapent' 2536 ............................. 2537 2538 *Synopsis* 2539 symindex bfd_get_next_mapent 2540 (bfd *abfd, symindex previous, carsym **sym); 2541 *Description* 2542 Step through archive ABFD's symbol table (if it has one).

The symbol is referenced through a pointer to a pointer so 2749 that tools like the linker can fix up all the symbols of the same name 2750 by modifying only one pointer. The relocation routine looks in the 2751 symbol and uses the base of the section the symbol is attached to and 2752 the value of the symbol as the initial relocation offset. If the symbol 2753 pointer is zero, then the section provided is looked up. 2754 2755 * `address' 2756 The `address' field gives the offset in bytes from the base of the 2757 section data which owns the relocation record to the first byte of 2758 relocatable information. The actual data relocated will be relative to 2759 this point; for example, a relocation type which modifies the bottom 2760 two bytes of a four byte word would not touch the first byte pointed to 2761 in a big endian world. 2762 2763 * `addend' 2764 The `addend' is a value provided by the back end to be added (!) to 2765 the relocation offset. Its interpretation is dependent upon the howto. 2766 For example, on the 68k the code: 2767 2768 char foo[]; 2769 main() 2770 { 2771 return foo[0x12345678]; 2772 } 2773 2774 Could be compiled into: 2775 2776 linkw fp,#-4 2777 moveb @#12345678,d0 2778 extbl d0 2779 unlk fp 2780 rts 2781 2782 This could create a reloc pointing to `foo', but leave the offset in 2783 the data, something like: 2784 2785 RELOCATION RECORDS FOR [.text]: 2786 offset type value 2787 00000006 32 _foo 2788 2789 00000000 4e56 fffc ; linkw fp,#-4 2790 00000004 1039 1234 5678 ; moveb @#12345678,d0 2791 0000000a 49c0 ; extbl d0 2792 0000000c 4e5e ; unlk fp 2793 0000000e 4e75 ; rts 2794 2795 Using coff and an 88k, some instructions don't have enough space in 2796 them to represent the full address range, and pointers have to be 2797 loaded in two parts. So you'd get something like: 2798 2799 or.u r13,r0,hi16(_foo+0x12345678) 2800 ld.b r2,r13,lo16(_foo+0x12345678) 2801 jmp r1 2802 2803 This should create two relocs, both pointing to `_foo', and with 2804 0x12340000 in their addend field. The data would consist of: 2805 2806 RELOCATION RECORDS FOR [.text]: 2807 offset type value 2808 00000002 HVRT16 _foo+0x12340000 2809 00000006 LVRT16 _foo+0x12340000 2810 2811 00000000 5da05678 ; or.u r13,r0,0x5678 2812 00000004 1c4d5678 ; ld.b r2,r13,0x5678 2813 00000008 f400c001 ; jmp r1 2814 2815 The relocation routine digs out the value from the data, adds it to 2816 the addend to get the original offset, and then adds the value of 2817 `_foo'. Note that all 32 bits have to be kept around somewhere, to cope 2818 with carry from bit 15 to bit 16. 2819 2820 One further example is the sparc and the a.out format. The sparc has 2821 a similar problem to the 88k, in that some instructions don't have room 2822 for an entire offset, but on the sparc the parts are created in odd 2823 sized lumps. The designers of the a.out format chose to not use the 2824 data within the section for storing part of the offset; all the offset 2825 is kept within the reloc. Anything in the data should be ignored. 2826 2827 save %sp,-112,%sp 2828 sethi %hi(_foo+0x12345678),%g2 2829 ldsb [%g2+%lo(_foo+0x12345678)],%i0 2830 ret 2831 restore 2832 2833 Both relocs contain a pointer to `foo', and the offsets contain junk. 2834 2835 RELOCATION RECORDS FOR [.text]: 2836 offset type value 2837 00000004 HI22 _foo+0x12345678 2838 00000008 LO10 _foo+0x12345678 2839 2840 00000000 9de3bf90 ; save %sp,-112,%sp 2841 00000004 05000000 ; sethi %hi(_foo+0),%g2 2842 00000008 f048a000 ; ldsb [%g2+%lo(_foo+0)],%i0 2843 0000000c 81c7e008 ; ret 2844 00000010 81e80000 ; restore 2845 2846 * `howto' 2847 The `howto' field can be imagined as a relocation instruction. It is 2848 a pointer to a structure which contains information on what to do with 2849 all of the other information in the reloc record and data section. A 2850 back end would normally have a relocation instruction set and turn 2851 relocations into pointers to the correct structure on input - but it 2852 would be possible to create each howto field on demand. 2853 2854 2.10.1.1 `enum complain_overflow' 2855 ................................. 2856 2857 Indicates what sort of overflow checking should be done when performing 2858 a relocation. 2859 2860 2861 enum complain_overflow 2862 { 2863 /* Do not complain on overflow. */ 2864 complain_overflow_dont, 2865 2866 /* Complain if the value overflows when considered as a signed 2867 number one bit larger than the field. ie.

Some native formats (e.g., basic a.out and basic coff) have no 3069 way of specifying an addend in the relocation type, so the addend has 3070 to go in the output data. This is no big deal since in these formats 3071 the output data slot will always be big enough for the addend. Complex 3072 reloc types with addends were invented to solve just this problem.

Some of these treat the symbol or 3304 "addend" in some special way. For GPDISP_HI16 ("gpdisp") 3305 relocations, the symbol is ignored when writing; when reading, it 3306 will be the absolute section symbol. The addend is the 3307 displacement in bytes of the "lda" instruction from the "ldah" 3308 instruction (which is at the address of this reloc). 3309 3310 -- : BFD_RELOC_ALPHA_GPDISP_LO16 3311 For GPDISP_LO16 ("ignore") relocations, the symbol is handled as 3312 with GPDISP_HI16 relocs.

The addend is ignored when writing, but is filled 3331 in with the file's GP value on reading, for convenience, as with 3332 the GPDISP_LO16 reloc. 3333 3334 The ELF_LITERAL reloc is somewhere between 16_GOTOFF and 3335 GPDISP_LO16. It should refer to the symbol to be referenced, as 3336 with 16_GOTOFF, but it generates output not based on the position 3337 within the .got section, but relative to the GP value chosen for 3338 the file during the final link stage. 3339 3340 The LITUSE reloc, on the instruction using the loaded address, 3341 gives information to the linker that it might be able to use to 3342 optimize away some literal section references. The symbol is 3343 ignored (read as the absolute section symbol), and the "addend" 3344 indicates the type of instruction using the register: 1 - "memory" 3345 fmt insn 2 - byte-manipulation (byte offset reg) 3 - jsr (target 3346 of branch) 3347 3348 -- : BFD_RELOC_ALPHA_HINT 3349 The HINT relocation indicates a value that should be filled into 3350 the "hint" field of a jmp/jsr/ret instruction, for possible branch- 3351 prediction logic which may be provided on some processors. 3352 3353 -- : BFD_RELOC_ALPHA_LINKAGE 3354 The LINKAGE relocation outputs a linkage pair in the object file, 3355 which is filled by the linker. 3356 3357 -- : BFD_RELOC_ALPHA_CODEADDR 3358 The CODEADDR relocation outputs a STO_CA in the object file, which 3359 is filled by the linker. 3360 3361 -- : BFD_RELOC_ALPHA_GPREL_HI16 3362 -- : BFD_RELOC_ALPHA_GPREL_LO16 3363 The GPREL_HI/LO relocations together form a 32-bit offset from the 3364 GP register. 3365 3366 -- : BFD_RELOC_ALPHA_BRSGP 3367 Like BFD_RELOC_23_PCREL_S2, except that the source and target must 3368 share a common GP, and the target address is adjusted for 3369 STO_ALPHA_STD_GPLOAD. 3370 3371 -- : BFD_RELOC_ALPHA_TLSGD 3372 -- : BFD_RELOC_ALPHA_TLSLDM 3373 -- : BFD_RELOC_ALPHA_DTPMOD64 3374 -- : BFD_RELOC_ALPHA_GOTDTPREL16 3375 -- : BFD_RELOC_ALPHA_DTPREL64 3376 -- : BFD_RELOC_ALPHA_DTPREL_HI16 3377 -- : BFD_RELOC_ALPHA_DTPREL_LO16 3378 -- : BFD_RELOC_ALPHA_DTPREL16 3379 -- : BFD_RELOC_ALPHA_GOTTPREL16 3380 -- : BFD_RELOC_ALPHA_TPREL64 3381 -- : BFD_RELOC_ALPHA_TPREL_HI16 3382 -- : BFD_RELOC_ALPHA_TPREL_LO16 3383 -- : BFD_RELOC_ALPHA_TPREL16 3384 Alpha thread-local storage relocations. 3385 3386 -- : BFD_RELOC_MIPS_JMP 3387 Bits 27..2 of the relocation address shifted right 2 bits; simple 3388 reloc otherwise. 3389 3390 -- : BFD_RELOC_MIPS16_JMP 3391 The MIPS16 jump instruction. 3392 3393 -- : BFD_RELOC_MIPS16_GPREL 3394 MIPS16 GP relative reloc. 3395 3396 -- : BFD_RELOC_HI16 3397 High 16 bits of 32-bit value; simple reloc. 3398 3399 -- : BFD_RELOC_HI16_S 3400 High 16 bits of 32-bit value but the low 16 bits will be sign 3401 extended and added to form the final result.

All the back end provides to the root part of BFD is a 5249 structure containing pointers to functions which perform certain low 5250 level operations on files. BFD translates the applications's requests 5251 through a pointer into calls to the back end routines. 5252 5253 When a file is opened with `bfd_openr', its format and target are 5254 unknown. BFD uses various mechanisms to determine how to interpret the 5255 file. The operations performed are: 5256 5257 * Create a BFD by calling the internal routine `_bfd_new_bfd', then 5258 call `bfd_find_target' with the target string supplied to 5259 `bfd_openr' and the new BFD pointer. 5260 5261 * If a null target string was provided to `bfd_find_target', look up 5262 the environment variable `GNUTARGET' and use that as the target 5263 string. 5264 5265 * If the target string is still `NULL', or the target string is 5266 `default', then use the first item in the target vector as the 5267 target type, and set `target_defaulted' in the BFD to cause 5268 `bfd_check_format' to loop through all the targets. *Note 5269 bfd_target::. *Note Formats::. 5270 5271 * Otherwise, inspect the elements in the target vector one by one, 5272 until a match on target name is found. When found, use it. 5273 5274 * Otherwise return the error `bfd_error_invalid_target' to 5275 `bfd_openr'. 5276 5277 * `bfd_openr' attempts to open the file using `bfd_open_file', and 5278 returns the BFD. 5279 Once the BFD has been opened and the target selected, the file 5280 format may be determined. This is done by calling `bfd_check_format' on 5281 the BFD with a suggested format. If `target_defaulted' has been set, 5282 each possible target type is tried to see if it recognizes the 5283 specified format. `bfd_check_format' returns `TRUE' when the caller 5284 guesses right. 5285 5286 * Menu: 5287 5288 * bfd_target:: 5289 5290 5291 File: bfd.info, Node: bfd_target, Prev: Targets, Up: Targets 5292 5293 2.12.1 bfd_target 5294 ----------------- 5295 5296 *Description* 5297 This structure contains everything that BFD knows about a target. It 5298 includes things like its byte order, name, and which routines to call 5299 to do various operations. 5300 5301 Every BFD points to a target structure with its `xvec' member. 5302 5303 The macros below are used to dispatch to functions through the 5304 `bfd_target' vector. They are used in a number of macros further down 5305 in `bfd.h', and are also used when calling various routines by hand 5306 inside the BFD implementation. The ARGLIST argument must be 5307 parenthesized; it contains all the arguments to the called function. 5308 5309 They make the documentation (more) unpleasant to read, so if someone 5310 wants to fix this and not break the above, please do. 5311 #define BFD_SEND(bfd, message, arglist) \ 5312 ((*((bfd)->xvec->message)) arglist) 5313 5314 #ifdef DEBUG_BFD_SEND 5315 #undef BFD_SEND 5316 #define BFD_SEND(bfd, message, arglist) \ 5317 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \ 5318 ((*((bfd)->xvec->message)) arglist) : \ 5319 (bfd_assert (__FILE__,__LINE__), NULL)) 5320 #endif 5321 For operations which index on the BFD format: 5322 #define BFD_SEND_FMT(bfd, message, arglist) \ 5323 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) 5324 5325 #ifdef DEBUG_BFD_SEND 5326 #undef BFD_SEND_FMT 5327 #define BFD_SEND_FMT(bfd, message, arglist) \ 5328 (((bfd) && (bfd)->xvec && (bfd)->xvec->message) ? \ 5329 (((bfd)->xvec->message[(int) ((bfd)->format)]) arglist) : \ 5330 (bfd_assert (__FILE__,__LINE__), NULL)) 5331 #endif 5332 This is the structure which defines the type of BFD this is.

It is up to the architecture back end to insert as 5784 many items into the list of architectures as it wants to; generally 5785 this would be one for each machine and one for the default case (an 5786 item with a machine field of 0). 5787 5788 BFD's idea of an architecture is implemented in `archures.c'. 5789 5790 2.13.1 bfd_architecture 5791 ----------------------- 5792 5793 *Description* 5794 This enum gives the object file's CPU architecture, in a global 5795 sense--i.e., what processor family does it belong to? Another field 5796 indicates which processor within the family is in use. The machine 5797 gives a number which distinguishes different versions of the 5798 architecture, containing, for example, 2 and 3 for Intel i960 KA and 5799 i960 KB, and 68020 and 68030 for Motorola 68020 and 68030. 5800 enum bfd_architecture 5801 { 5802 bfd_arch_unknown, /* File arch not known. */ 5803 bfd_arch_obscure, /* Arch known, not one of these. */ 5804 bfd_arch_m68k, /* Motorola 68xxx */

Return a pointer to the 6342 created BFD. If FD is not -1, then `fdopen' is used to open the file; 6343 otherwise, `fopen' is used. MODE is passed directly to `fopen' or 6344 `fdopen'. 6345 6346 Calls `bfd_find_target', so TARGET is interpreted as by that 6347 function. 6348 6349 The new BFD is marked as cacheable iff FD is -1. 6350 6351 If `NULL' is returned then an error has occured.

Return 6362 a pointer to the created BFD. 6363 6364 Calls `bfd_find_target', so TARGET is interpreted as by that 6365 function. 6366 6367 If `NULL' is returned then an error has occured. Possible errors 6368 are `bfd_error_no_memory', `bfd_error_invalid_target' or `system_call' 6369 error. 6370 6371 2.14.1.3 `bfd_fdopenr' 6372 ...................... 6373 6374 *Synopsis* 6375 bfd *bfd_fdopenr (const char *filename, const char *target, int fd); 6376 *Description* 6377 `bfd_fdopenr' is to `bfd_fopenr' much like `fdopen' is to `fopen'. It 6378 opens a BFD on a file already described by the FD supplied. 6379 6380 When the file is later `bfd_close'd, the file descriptor will be 6381 closed. If the caller desires that this file descriptor be cached by 6382 BFD (opened as needed, closed as needed to free descriptors for other 6383 opens), with the supplied FD used as an initial file descriptor (but 6384 subject to closure at any time), call bfd_set_cacheable(bfd, 1) on the 6385 returned BFD. The default is to assume no caching; the file descriptor 6386 will remain open until `bfd_close', and will not be affected by BFD 6387 operations on other files. 6388 6389 Possible errors are `bfd_error_no_memory', 6390 `bfd_error_invalid_target' and `bfd_error_system_call'. 6391 6392 2.14.1.4 `bfd_openstreamr' 6393 .......................... 6394 6395 *Synopsis* 6396 bfd *bfd_openstreamr (const char *, const char *, void *); 6397 *Description* 6398 Open a BFD for read access on an existing stdio stream.

The STREAM is 6418 created using OPEN, accessed using PREAD and destroyed using CLOSE. 6419 6420 Calls `bfd_find_target', so TARGET is interpreted as by that 6421 function. 6422 6423 Calls OPEN (which can call `bfd_zalloc' and `bfd_get_filename') to 6424 obtain the read-only stream backing the BFD. OPEN either succeeds 6425 returning the non-`NULL' STREAM, or fails returning `NULL' (setting 6426 `bfd_error'). 6427 6428 Calls PREAD to request NBYTES of data from STREAM starting at OFFSET 6429 (e.g., via a call to `bfd_read'). PREAD either succeeds returning the 6430 number of bytes read (which can be less than NBYTES when end-of-file), 6431 or fails returning -1 (setting `bfd_error'). 6432 6433 Calls CLOSE when the BFD is later closed using `bfd_close'. CLOSE 6434 either succeeds returning 0, or fails returning -1 (setting 6435 `bfd_error'). 6436 6437 If `bfd_openr_iovec' returns `NULL' then an error has occurred. 6438 Possible errors are `bfd_error_no_memory', `bfd_error_invalid_target' 6439 and `bfd_error_system_call'. 6440 6441 2.14.1.6 `bfd_openw' 6442 .................... 6443 6444 *Synopsis* 6445 bfd *bfd_openw (const char *filename, const char *target); 6446 *Description* 6447 Create a BFD, associated with file FILENAME, using the file format 6448 TARGET, and return a pointer to it. 6449 6450 Possible errors are `bfd_error_system_call', `bfd_error_no_memory', 6451 `bfd_error_invalid_target'. 6452 6453 2.14.1.7 `bfd_close' 6454 .................... 6455 6456 *Synopsis* 6457 bfd_boolean bfd_close (bfd *abfd); 6458 *Description* 6459 Close a BFD. If the BFD was open for writing, then pending operations 6460 are completed and the file written out and closed. If the created file 6461 is executable, then `chmod' is called to mark it as such. 6462 6463 All memory attached to the BFD is released. 6464 6465 The file descriptor associated with the BFD is closed (even if it 6466 was passed in to BFD by `bfd_fdopenr'). 6467 6468 *Returns* 6469 `TRUE' is returned if all is ok, otherwise `FALSE'. 6470 6471 2.14.1.8 `bfd_close_all_done' 6472 ............................. 6473 6474 *Synopsis* 6475 bfd_boolean bfd_close_all_done (bfd *); 6476 *Description* 6477 Close a BFD. Differs from `bfd_close' since it does not complete any 6478 pending operations. This routine would be used if the application had 6479 just used BFD for swapping and didn't want to use any of the writing 6480 code. 6481 6482 If the created file is executable, then `chmod' is called to mark it 6483 as such. 6484 6485 All memory attached to the BFD is released. 6486 6487 *Returns* 6488 `TRUE' is returned if all is ok, otherwise `FALSE'. 6489 6490 2.14.1.9 `bfd_create' 6491 ..................... 6492 6493 *Synopsis* 6494 bfd *bfd_create (const char *filename, bfd *templ); 6495 *Description* 6496 Create a new BFD in the manner of `bfd_openw', but without opening a 6497 file.

They are not intended for export, 6670 but are documented here for completeness. 6671 6672 2.15.1.1 `bfd_write_bigendian_4byte_int' 6673 ........................................ 6674 6675 *Synopsis* 6676 bfd_boolean bfd_write_bigendian_4byte_int (bfd *, unsigned int); 6677 *Description* 6678 Write a 4 byte integer I to the output BFD ABFD, in big endian order 6679 regardless of what else is going on. This is useful in archives. 6680 6681 2.15.1.2 `bfd_put_size' 6682 ....................... 6683 6684 2.15.1.3 `bfd_get_size' 6685 ....................... 6686 6687 *Description* 6688 These macros as used for reading and writing raw data in sections; each 6689 access (except for bytes) is vectored through the target format of the 6690 BFD and mangled accordingly. The mangling performs any necessary endian 6691 translations and removes alignment restrictions. Note that types 6692 accepted and returned by these macros are identical so they can be 6693 swapped around in macros--for example, `libaout.h' defines `GET_WORD' 6694 to either `bfd_get_32' or `bfd_get_64'. 6695 6696 In the put routines, VAL must be a `bfd_vma'. If we are on a system 6697 without prototypes, the caller is responsible for making sure that is 6698 true, with a cast if necessary.

The module in `cache.c' maintains a least recently used 6842 list of `BFD_CACHE_MAX_OPEN' files, and exports the name 6843 `bfd_cache_lookup', which runs around and makes sure that the required 6844 BFD is open. If not, then it chooses a file to close, closes it and 6845 opens the one wanted, returning its file handle. 6846 6847 2.16.1 Caching functions 6848 ------------------------ 6849 6850 2.16.1.1 `bfd_cache_init' 6851 ......................... 6852 6853 *Synopsis* 6854 bfd_boolean bfd_cache_init (bfd *abfd); 6855 *Description* 6856 Add a newly opened BFD to the cache. 6857 6858 2.16.1.2 `bfd_cache_close' 6859 .......................... 6860 6861 *Synopsis* 6862 bfd_boolean bfd_cache_close (bfd *abfd); 6863 *Description* 6864 Remove the BFD ABFD from the cache.

The third routine takes all the object files and links them 6911 together to create the output file. These routines are designed so 6912 that the linker proper does not need to know anything about the symbols 6913 in the object files that it is linking. The linker merely arranges the 6914 sections as directed by the linker script and lets BFD handle the 6915 details of symbols and relocs. 6916 6917 The second routine and third routines are passed a pointer to a 6918 `struct bfd_link_info' structure (defined in `bfdlink.h') which holds 6919 information relevant to the link, including the linker hash table 6920 (which was created by the first routine) and a set of callback 6921 functions to the linker proper. 6922 6923 The generic linker routines are in `linker.c', and use the header 6924 file `genlink.h'. As of this writing, the only back ends which have 6925 implemented versions of these routines are a.out (in `aoutx.h') and 6926 ECOFF (in `ecoff.c'). The a.out routines are used as examples 6927 throughout this section. 6928 6929 * Menu: 6930 6931 * Creating a Linker Hash Table:: 6932 * Adding Symbols to the Hash Table:: 6933 * Performing the Final Link:: 6934 6935 6936 File: bfd.info, Node: Creating a Linker Hash Table, Next: Adding Symbols to the Hash Table, Prev: Linker Functions, Up: Linker Functions 6937 6938 2.17.1 Creating a linker hash table 6939 ----------------------------------- 6940 6941 The linker routines must create a hash table, which must be derived 6942 from `struct bfd_link_hash_table' described in `bfdlink.c'. *Note Hash 6943 Tables::, for information on how to create a derived hash table. This 6944 entry point is called using the target vector of the linker output file. 6945 6946 The `_bfd_link_hash_table_create' entry point must allocate and 6947 initialize an instance of the desired hash table. If the back end does 6948 not require any additional information to be stored with the entries in 6949 the hash table, the entry point may simply create a `struct 6950 bfd_link_hash_table'. Most likely, however, some additional 6951 information will be needed. 6952 6953 For example, with each entry in the hash table the a.out linker 6954 keeps the index the symbol has in the final output file (this index 6955 number is used so that when doing a relocatable link the symbol index 6956 used in the output file can be quickly filled in when copying over a 6957 reloc). The a.out linker code defines the required structures and 6958 functions for a hash table derived from `struct bfd_link_hash_table'. 6959 The a.out linker hash table is created by the function 6960 `NAME(aout,link_hash_table_create)'; it simply allocates space for the 6961 hash table, initializes it, and returns a pointer to it. 6962 6963 When writing the linker routines for a new back end, you will 6964 generally not know exactly which fields will be required until you have 6965 finished. You should simply create a new hash table which defines no 6966 additional fields, and then simply add fields as they become necessary. 6967 6968 6969 File: bfd.info, Node: Adding Symbols to the Hash Table, Next: Performing the Final Link, Prev: Creating a Linker Hash Table, Up: Linker Functions 6970 6971 2.17.2 Adding symbols to the hash table 6972 --------------------------------------- 6973 6974 The linker proper will call the `_bfd_link_add_symbols' entry point for 6975 each object file or archive which is to be linked (typically these are 6976 the files named on the command line, but some may also come from the 6977 linker script). The entry point is responsible for examining the file. 6978 For an object file, BFD must add any relevant symbol information to 6979 the hash table. For an archive, BFD must determine which elements of 6980 the archive should be used and adding them to the link. 6981 6982 The a.out version of this entry point is 6983 `NAME(aout,link_add_symbols)'. 6984 6985 * Menu: 6986 6987 * Differing file formats:: 6988 * Adding symbols from an object file:: 6989 * Adding symbols from an archive:: 6990 6991 6992 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 6993 6994 2.17.2.1 Differing file formats 6995 ............................... 6996 6997 Normally all the files involved in a link will be of the same format, 6998 but it is also possible to link together different format object files, 6999 and the back end must support that. The `_bfd_link_add_symbols' entry 7000 point is called via the target vector of the file to be added. This 7001 has an important consequence: the function may not assume that the hash 7002 table is the type created by the corresponding 7003 `_bfd_link_hash_table_create' vector. All the `_bfd_link_add_symbols' 7004 function can assume about the hash table is that it is derived from 7005 `struct bfd_link_hash_table'. 7006 7007 Sometimes the `_bfd_link_add_symbols' function must store some 7008 information in the hash table entry to be used by the `_bfd_final_link' 7009 function. In such a case the `creator' field of the hash table must be 7010 checked to make sure that the hash table was created by an object file 7011 of the same format. 7012 7013 The `_bfd_final_link' routine must be prepared to handle a hash 7014 entry without any extra information added by the 7015 `_bfd_link_add_symbols' function. A hash entry without extra 7016 information will also occur when the linker script directs the linker 7017 to create a symbol. Note that, regardless of how a hash table entry is 7018 added, all the fields will be initialized to some sort of null value by 7019 the hash table entry initialization function. 7020 7021 See `ecoff_link_add_externals' for an example of how to check the 7022 `creator' field before saving information (in this case, the ECOFF 7023 external symbol debugging information) in a hash table entry. 7024 7025 7026 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 7027 7028 2.17.2.2 Adding symbols from an object file 7029 ........................................... 7030 7031 When the `_bfd_link_add_symbols' routine is passed an object file, it 7032 must add all externally visible symbols in that object file to the hash 7033 table. The actual work of adding the symbol to the hash table is 7034 normally handled by the function `_bfd_generic_link_add_one_symbol'. 7035 The `_bfd_link_add_symbols' routine is responsible for reading all the 7036 symbols from the object file and passing the correct information to 7037 `_bfd_generic_link_add_one_symbol'. 7038 7039 The `_bfd_link_add_symbols' routine should not use 7040 `bfd_canonicalize_symtab' to read the symbols. The point of providing 7041 this routine is to avoid the overhead of converting the symbols into 7042 generic `asymbol' structures. 7043 7044 `_bfd_generic_link_add_one_symbol' handles the details of combining 7045 common symbols, warning about multiple definitions, and so forth. It 7046 takes arguments which describe the symbol to add, notably symbol flags, 7047 a section, and an offset. The symbol flags include such things as 7048 `BSF_WEAK' or `BSF_INDIRECT'. The section is a section in the object 7049 file, or something like `bfd_und_section_ptr' for an undefined symbol 7050 or `bfd_com_section_ptr' for a common symbol. 7051 7052 If the `_bfd_final_link' routine is also going to need to read the 7053 symbol information, the `_bfd_link_add_symbols' routine should save it 7054 somewhere attached to the object file BFD. However, the information 7055 should only be saved if the `keep_memory' field of the `info' argument 7056 is TRUE, so that the `-no-keep-memory' linker switch is effective. 7057 7058 The a.out function which adds symbols from an object file is 7059 `aout_link_add_object_symbols', and most of the interesting work is in 7060 `aout_link_add_symbols'. The latter saves pointers to the hash tables 7061 entries created by `_bfd_generic_link_add_one_symbol' indexed by symbol 7062 number, so that the `_bfd_final_link' routine does not have to call the 7063 hash table lookup routine to locate the entry. 7064 7065 7066 File: bfd.info, Node: Adding symbols from an archive, Prev: Adding symbols from an object file, Up: Adding Symbols to the Hash Table 7067 7068 2.17.2.3 Adding symbols from an archive 7069 ....................................... 7070 7071 When the `_bfd_link_add_symbols' routine is passed an archive, it must 7072 look through the symbols defined by the archive and decide which 7073 elements of the archive should be included in the link. For each such 7074 element it must call the `add_archive_element' linker callback, and it 7075 must add the symbols from the object file to the linker hash table. 7076 7077 In most cases the work of looking through the symbols in the archive 7078 should be done by the `_bfd_generic_link_add_archive_symbols' function. 7079 This function builds a hash table from the archive symbol table and 7080 looks through the list of undefined symbols to see which elements 7081 should be included. `_bfd_generic_link_add_archive_symbols' is passed 7082 a function to call to make the final decision about adding an archive 7083 element to the link and to do the actual work of adding the symbols to 7084 the linker hash table. 7085 7086 The function passed to `_bfd_generic_link_add_archive_symbols' must 7087 read the symbols of the archive element and decide whether the archive 7088 element should be included in the link. If the element is to be 7089 included, the `add_archive_element' linker callback routine must be 7090 called with the element as an argument, and the elements symbols must 7091 be added to the linker hash table just as though the element had itself 7092 been passed to the `_bfd_link_add_symbols' function. 7093 7094 When the a.out `_bfd_link_add_symbols' function receives an archive, 7095 it calls `_bfd_generic_link_add_archive_symbols' passing 7096 `aout_link_check_archive_element' as the function argument. 7097 `aout_link_check_archive_element' calls `aout_link_check_ar_symbols'. 7098 If the latter decides to add the element (an element is only added if 7099 it provides a real, non-common, definition for a previously undefined 7100 or common symbol) it calls the `add_archive_element' callback and then 7101 `aout_link_check_archive_element' calls `aout_link_add_symbols' to 7102 actually add the symbols to the linker hash table. 7103 7104 The ECOFF back end is unusual in that it does not normally call 7105 `_bfd_generic_link_add_archive_symbols', because ECOFF archives already 7106 contain a hash table of symbols. The ECOFF back end searches the 7107 archive itself to avoid the overhead of creating a new hash table. 7108 7109 7110 File: bfd.info, Node: Performing the Final Link, Prev: Adding Symbols to the Hash Table, Up: Linker Functions 7111 7112 2.17.3 Performing the final link 7113 -------------------------------- 7114 7115 When all the input files have been processed, the linker calls the 7116 `_bfd_final_link' entry point of the output BFD. This routine is 7117 responsible for producing the final output file, which has several 7118 aspects. It must relocate the contents of the input sections and copy 7119 the data into the output sections. It must build an output symbol 7120 table including any local symbols from the input files and the global 7121 symbols from the hash table. When producing relocatable output, it must 7122 modify the input relocs and write them into the output file. There may 7123 also be object format dependent work to be done. 7124 7125 The linker will also call the `write_object_contents' entry point 7126 when the BFD is closed. The two entry points must work together in 7127 order to produce the correct output file. 7128 7129 The details of how this works are inevitably dependent upon the 7130 specific object file format. The a.out `_bfd_final_link' routine is 7131 `NAME(aout,final_link)'. 7132 7133 * Menu: 7134 7135 * Information provided by the linker:: 7136 * Relocating the section contents:: 7137 * Writing the symbol table:: 7138 7139 7140 File: bfd.info, Node: Information provided by the linker, Next: Relocating the section contents, Prev: Performing the Final Link, Up: Performing the Final Link 7141 7142 2.17.3.1 Information provided by the linker 7143 ........................................... 7144 7145 Before the linker calls the `_bfd_final_link' entry point, it sets up 7146 some data structures for the function to use. 7147 7148 The `input_bfds' field of the `bfd_link_info' structure will point 7149 to a list of all the input files included in the link. These files are 7150 linked through the `link_next' field of the `bfd' structure. 7151 7152 Each section in the output file will have a list of `link_order' 7153 structures attached to the `map_head.link_order' field (the 7154 `link_order' structure is defined in `bfdlink.h'). These structures 7155 describe how to create the contents of the output section in terms of 7156 the contents of various input sections, fill constants, and, 7157 eventually, other types of information. They also describe relocs that 7158 must be created by the BFD backend, but do not correspond to any input 7159 file; this is used to support -Ur, which builds constructors while 7160 generating a relocatable object file. 7161 7162 7163 File: bfd.info, Node: Relocating the section contents, Next: Writing the symbol table, Prev: Information provided by the linker, Up: Performing the Final Link 7164 7165 2.17.3.2 Relocating the section contents 7166 ........................................ 7167 7168 The `_bfd_final_link' function should look through the `link_order' 7169 structures attached to each section of the output file. Each 7170 `link_order' structure should either be handled specially, or it should 7171 be passed to the function `_bfd_default_link_order' which will do the 7172 right thing (`_bfd_default_link_order' is defined in `linker.c'). 7173 7174 For efficiency, a `link_order' of type `bfd_indirect_link_order' 7175 whose associated section belongs to a BFD of the same format as the 7176 output BFD must be handled specially. This type of `link_order' 7177 describes part of an output section in terms of a section belonging to 7178 one of the input files. The `_bfd_final_link' function should read the 7179 contents of the section and any associated relocs, apply the relocs to 7180 the section contents, and write out the modified section contents. If 7181 performing a relocatable link, the relocs themselves must also be 7182 modified and written out. 7183 7184 The functions `_bfd_relocate_contents' and 7185 `_bfd_final_link_relocate' provide some general support for performing 7186 the actual relocations, notably overflow checking. Their arguments 7187 include information about the symbol the relocation is against and a 7188 `reloc_howto_type' argument which describes the relocation to perform. 7189 These functions are defined in `reloc.c'. 7190 7191 The a.out function which handles reading, relocating, and writing 7192 section contents is `aout_link_input_section'. The actual relocation 7193 is done in `aout_link_input_section_std' and 7194 `aout_link_input_section_ext'. 7195 7196 7197 File: bfd.info, Node: Writing the symbol table, Prev: Relocating the section contents, Up: Performing the Final Link 7198 7199 2.17.3.3 Writing the symbol table 7200 ................................. 7201 7202 The `_bfd_final_link' function must gather all the symbols in the input 7203 files and write them out. It must also write out all the symbols in 7204 the global hash table. This must be controlled by the `strip' and 7205 `discard' fields of the `bfd_link_info' structure. 7206 7207 The local symbols of the input files will not have been entered into 7208 the linker hash table. The `_bfd_final_link' routine must consider 7209 each input file and include the symbols in the output file. It may be 7210 convenient to do this when looking through the `link_order' structures, 7211 or it may be done by stepping through the `input_bfds' list. 7212 7213 The `_bfd_final_link' routine must also traverse the global hash 7214 table to gather all the externally visible symbols. It is possible 7215 that most of the externally visible symbols may be written out when 7216 considering the symbols of each input file, but it is still necessary 7217 to traverse the hash table since the linker script may have defined 7218 some symbols that are not in any of the input files. 7219 7220 The `strip' field of the `bfd_link_info' structure controls which 7221 symbols are written out. The possible values are listed in 7222 `bfdlink.h'. If the value is `strip_some', then the `keep_hash' field 7223 of the `bfd_link_info' structure is a hash table of symbols to keep; 7224 each symbol should be looked up in this hash table, and only symbols 7225 which are present should be included in the output file. 7226 7227 If the `strip' field of the `bfd_link_info' structure permits local 7228 symbols to be written out, the `discard' field is used to further 7229 controls which local symbols are included in the output file. If the 7230 value is `discard_l', then all local symbols which begin with a certain 7231 prefix are discarded; this is controlled by the 7232 `bfd_is_local_label_name' entry point. 7233 7234 The a.out backend handles symbols by calling 7235 `aout_link_write_symbols' on each input BFD and then traversing the 7236 global hash table with the function `aout_link_write_other_symbol'. It 7237 builds a string table while writing out the symbols, which is written 7238 to the output file at the end of `NAME(aout,final_link)'. 7239 7240 2.17.3.4 `bfd_link_split_section' 7241 ................................. 7242 7243 *Synopsis* 7244 bfd_boolean bfd_link_split_section (bfd *abfd, asection *sec); 7245 *Description* 7246 Return nonzero if SEC should be split during a reloceatable or final 7247 link. 7248 #define bfd_link_split_section(abfd, sec) \ 7249 BFD_SEND (abfd, _bfd_link_split_section, (abfd, sec)) 7250 7251 2.17.3.5 `bfd_section_already_linked' 7252 ..................................... 7253 7254 *Synopsis* 7255 void bfd_section_already_linked (bfd *abfd, asection *sec, 7256 struct bfd_link_info *info); 7257 *Description* 7258 Check if SEC has been already linked during a reloceatable or final 7259 link. 7260 #define bfd_section_already_linked(abfd, sec, info) \ 7261 BFD_SEND (abfd, _section_already_linked, (abfd, sec, info)) 7262 7263 7264 File: bfd.info, Node: Hash Tables, Prev: Linker Functions, Up: BFD front end 7265 7266 2.18 Hash Tables 7267 ================ 7268 7269 BFD provides a simple set of hash table functions. Routines are 7270 provided to initialize a hash table, to free a hash table, to look up a 7271 string in a hash table and optionally create an entry for it, and to 7272 traverse a hash table. There is currently no routine to delete an 7273 string from a hash table. 7274 7275 The basic hash table does not permit any data to be stored with a 7276 string. However, a hash table is designed to present a base class from 7277 which other types of hash tables may be derived. These derived types 7278 may store additional information with the string. Hash tables were 7279 implemented in this way, rather than simply providing a data pointer in 7280 a hash table entry, because they were designed for use by the linker 7281 back ends. The linker may create thousands of hash table entries, and 7282 the overhead of allocating private data and storing and following 7283 pointers becomes noticeable. 7284 7285 The basic hash table code is in `hash.c'. 7286 7287 * Menu: 7288 7289 * Creating and Freeing a Hash Table:: 7290 * Looking Up or Entering a String:: 7291 * Traversing a Hash Table:: 7292 * Deriving a New Hash Table Type:: 7293 7294 7295 File: bfd.info, Node: Creating and Freeing a Hash Table, Next: Looking Up or Entering a String, Prev: Hash Tables, Up: Hash Tables 7296 7297 2.18.1 Creating and freeing a hash table 7298 ---------------------------------------- 7299 7300 To create a hash table, create an instance of a `struct bfd_hash_table' 7301 (defined in `bfd.h') and call `bfd_hash_table_init' (if you know 7302 approximately how many entries you will need, the function 7303 `bfd_hash_table_init_n', which takes a SIZE argument, may be used). 7304 `bfd_hash_table_init' returns `FALSE' if some sort of error occurs. 7305 7306 The function `bfd_hash_table_init' take as an argument a function to 7307 use to create new entries. For a basic hash table, use the function 7308 `bfd_hash_newfunc'. *Note Deriving a New Hash Table Type::, for why 7309 you would want to use a different value for this argument. 7310 7311 `bfd_hash_table_init' will create an objalloc which will be used to 7312 allocate new entries. You may allocate memory on this objalloc using 7313 `bfd_hash_allocate'. 7314 7315 Use `bfd_hash_table_free' to free up all the memory that has been 7316 allocated for a hash table. This will not free up the `struct 7317 bfd_hash_table' itself, which you must provide. 7318 7319 Use `bfd_hash_set_default_size' to set the default size of hash 7320 table to use. 7321 7322 7323 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 7324 7325 2.18.2 Looking up or entering a string 7326 -------------------------------------- 7327 7328 The function `bfd_hash_lookup' is used both to look up a string in the 7329 hash table and to create a new entry. 7330 7331 If the CREATE argument is `FALSE', `bfd_hash_lookup' will look up a 7332 string. If the string is found, it will returns a pointer to a `struct 7333 bfd_hash_entry'. If the string is not found in the table 7334 `bfd_hash_lookup' will return `NULL'. You should not modify any of the 7335 fields in the returns `struct bfd_hash_entry'. 7336 7337 If the CREATE argument is `TRUE', the string will be entered into 7338 the hash table if it is not already there. Either way a pointer to a 7339 `struct bfd_hash_entry' will be returned, either to the existing 7340 structure or to a newly created one. In this case, a `NULL' return 7341 means that an error occurred. 7342 7343 If the CREATE argument is `TRUE', and a new entry is created, the 7344 COPY argument is used to decide whether to copy the string onto the 7345 hash table objalloc or not. If COPY is passed as `FALSE', you must be 7346 careful not to deallocate or modify the string as long as the hash table 7347 exists. 7348 7349 7350 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 7351 7352 2.18.3 Traversing a hash table 7353 ------------------------------ 7354 7355 The function `bfd_hash_traverse' may be used to traverse a hash table, 7356 calling a function on each element. The traversal is done in a random 7357 order. 7358 7359 `bfd_hash_traverse' takes as arguments a function and a generic 7360 `void *' pointer. The function is called with a hash table entry (a 7361 `struct bfd_hash_entry *') and the generic pointer passed to 7362 `bfd_hash_traverse'. The function must return a `boolean' value, which 7363 indicates whether to continue traversing the hash table. If the 7364 function returns `FALSE', `bfd_hash_traverse' will stop the traversal 7365 and return immediately. 7366 7367 7368 File: bfd.info, Node: Deriving a New Hash Table Type, Prev: Traversing a Hash Table, Up: Hash Tables 7369 7370 2.18.4 Deriving a new hash table type 7371 ------------------------------------- 7372 7373 Many uses of hash tables want to store additional information which 7374 each entry in the hash table. Some also find it convenient to store 7375 additional information with the hash table itself. This may be done 7376 using a derived hash table. 7377 7378 Since C is not an object oriented language, creating a derived hash 7379 table requires sticking together some boilerplate routines with a few 7380 differences specific to the type of hash table you want to create. 7381 7382 An example of a derived hash table is the linker hash table. The 7383 structures for this are defined in `bfdlink.h'. The functions are in 7384 `linker.c'. 7385 7386 You may also derive a hash table from an already derived hash table. 7387 For example, the a.out linker backend code uses a hash table derived 7388 from the linker hash table. 7389 7390 * Menu: 7391 7392 * Define the Derived Structures:: 7393 * Write the Derived Creation Routine:: 7394 * Write Other Derived Routines:: 7395 7396 7397 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 7398 7399 2.18.4.1 Define the derived structures 7400 ...................................... 7401 7402 You must define a structure for an entry in the hash table, and a 7403 structure for the hash table itself. 7404 7405 The first field in the structure for an entry in the hash table must 7406 be of the type used for an entry in the hash table you are deriving 7407 from. If you are deriving from a basic hash table this is `struct 7408 bfd_hash_entry', which is defined in `bfd.h'. The first field in the 7409 structure for the hash table itself must be of the type of the hash 7410 table you are deriving from itself. If you are deriving from a basic 7411 hash table, this is `struct bfd_hash_table'. 7412 7413 For example, the linker hash table defines `struct 7414 bfd_link_hash_entry' (in `bfdlink.h'). The first field, `root', is of 7415 type `struct bfd_hash_entry'. Similarly, the first field in `struct 7416 bfd_link_hash_table', `table', is of type `struct bfd_hash_table'. 7417 7418 7419 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 7420 7421 2.18.4.2 Write the derived creation routine 7422 ........................................... 7423 7424 You must write a routine which will create and initialize an entry in 7425 the hash table. This routine is passed as the function argument to 7426 `bfd_hash_table_init'. 7427 7428 In order to permit other hash tables to be derived from the hash 7429 table you are creating, this routine must be written in a standard way. 7430 7431 The first argument to the creation routine is a pointer to a hash 7432 table entry. This may be `NULL', in which case the routine should 7433 allocate the right amount of space. Otherwise the space has already 7434 been allocated by a hash table type derived from this one. 7435 7436 After allocating space, the creation routine must call the creation 7437 routine of the hash table type it is derived from, passing in a pointer 7438 to the space it just allocated. This will initialize any fields used 7439 by the base hash table. 7440 7441 Finally the creation routine must initialize any local fields for 7442 the new hash table type. 7443 7444 Here is a boilerplate example of a creation routine. FUNCTION_NAME 7445 is the name of the routine. ENTRY_TYPE is the type of an entry in the 7446 hash table you are creating. BASE_NEWFUNC is the name of the creation 7447 routine of the hash table type your hash table is derived from. 7448 7449 struct bfd_hash_entry * 7450 FUNCTION_NAME (struct bfd_hash_entry *entry, 7451 struct bfd_hash_table *table, 7452 const char *string) 7453 { 7454 struct ENTRY_TYPE *ret = (ENTRY_TYPE *) entry; 7455 7456 /* Allocate the structure if it has not already been allocated by a 7457 derived class. */ 7458 if (ret == NULL) 7459 { 7460 ret = bfd_hash_allocate (table, sizeof (* ret)); 7461 if (ret == NULL) 7462 return NULL; 7463 } 7464 7465 /* Call the allocation method of the base class. */ 7466 ret = ((ENTRY_TYPE *) 7467 BASE_NEWFUNC ((struct bfd_hash_entry *) ret, table, string)); 7468 7469 /* Initialize the local fields here. */ 7470 7471 return (struct bfd_hash_entry *) ret; 7472 } 7473 *Description* 7474 The creation routine for the linker hash table, which is in `linker.c', 7475 looks just like this example. FUNCTION_NAME is 7476 `_bfd_link_hash_newfunc'. ENTRY_TYPE is `struct bfd_link_hash_entry'. 7477 BASE_NEWFUNC is `bfd_hash_newfunc', the creation routine for a basic 7478 hash table. 7479 7480 `_bfd_link_hash_newfunc' also initializes the local fields in a 7481 linker hash table entry: `type', `written' and `next'. 7482 7483 7484 File: bfd.info, Node: Write Other Derived Routines, Prev: Write the Derived Creation Routine, Up: Deriving a New Hash Table Type 7485 7486 2.18.4.3 Write other derived routines 7487 ..................................... 7488 7489 You will want to write other routines for your new hash table, as well. 7490 7491 You will want an initialization routine which calls the 7492 initialization routine of the hash table you are deriving from and 7493 initializes any other local fields. For the linker hash table, this is 7494 `_bfd_link_hash_table_init' in `linker.c'. 7495 7496 You will want a lookup routine which calls the lookup routine of the 7497 hash table you are deriving from and casts the result. The linker hash 7498 table uses `bfd_link_hash_lookup' in `linker.c' (this actually takes an 7499 additional argument which it uses to decide how to return the looked up 7500 value). 7501 7502 You may want a traversal routine. This should just call the 7503 traversal routine of the hash table you are deriving from with 7504 appropriate casts. The linker hash table uses `bfd_link_hash_traverse' 7505 in `linker.c'. 7506 7507 These routines may simply be defined as macros. For example, the 7508 a.out backend linker hash table, which is derived from the linker hash 7509 table, uses macros for the lookup and traversal routines. These are 7510 `aout_link_hash_lookup' and `aout_link_hash_traverse' in aoutx.h. 7511 7512 7513 File: bfd.info, Node: BFD back ends, Next: GNU Free Documentation License, Prev: BFD front end, Up: Top 7514 7515 3 BFD back ends 7516 *************** 7517 7518 * Menu: 7519 7520 * What to Put Where:: 7521 * aout :: a.out backends 7522 * coff :: coff backends 7523 * elf :: elf backends 7524 * mmo :: mmo backend 7525 7526 7527 File: bfd.info, Node: What to Put Where, Next: aout, Prev: BFD back ends, Up: BFD back ends 7528 7529 3.1 What to Put Where 7530 ===================== 7531 7532 All of BFD lives in one directory. 7533 7534 7535 File: bfd.info, Node: aout, Next: coff, Prev: What to Put Where, Up: BFD back ends 7536 7537 3.2 a.out backends 7538 ================== 7539 7540 *Description* 7541 BFD supports a number of different flavours of a.out format, though the 7542 major differences are only the sizes of the structures on disk, and the 7543 shape of the relocation information. 7544 7545 The support is split into a basic support file `aoutx.h' and other 7546 files which derive functions from the base. One derivation file is 7547 `aoutf1.h' (for a.out flavour 1), and adds to the basic a.out functions 7548 support for sun3, sun4, 386 and 29k a.out files, to create a target 7549 jump vector for a specific target. 7550 7551 This information is further split out into more specific files for 7552 each machine, including `sunos.c' for sun3 and sun4, `newsos3.c' for 7553 the Sony NEWS, and `demo64.c' for a demonstration of a 64 bit a.out 7554 format. 7555 7556 The base file `aoutx.h' defines general mechanisms for reading and 7557 writing records to and from disk and various other methods which BFD 7558 requires. It is included by `aout32.c' and `aout64.c' to form the names 7559 `aout_32_swap_exec_header_in', `aout_64_swap_exec_header_in', etc. 7560 7561 As an example, this is what goes on to make the back end for a sun4, 7562 from `aout32.c': 7563 7564 #define ARCH_SIZE 32 7565 #include "aoutx.h" 7566 7567 Which exports names: 7568 7569 ... 7570 aout_32_canonicalize_reloc 7571 aout_32_find_nearest_line 7572 aout_32_get_lineno 7573 aout_32_get_reloc_upper_bound 7574 ... 7575 7576 from `sunos.c': 7577 7578 #define TARGET_NAME "a.out-sunos-big" 7579 #define VECNAME sunos_big_vec 7580 #include "aoutf1.h" 7581 7582 requires all the names from `aout32.c', and produces the jump vector 7583 7584 sunos_big_vec 7585 7586 The file `host-aout.c' is a special case. It is for a large set of 7587 hosts that use "more or less standard" a.out files, and for which 7588 cross-debugging is not interesting. It uses the standard 32-bit a.out 7589 support routines, but determines the file offsets and addresses of the 7590 text, data, and BSS sections, the machine architecture and machine 7591 type, and the entry point address, in a host-dependent manner. Once 7592 these values have been determined, generic code is used to handle the 7593 object file. 7594 7595 When porting it to run on a new system, you must supply: 7596 7597 HOST_PAGE_SIZE 7598 HOST_SEGMENT_SIZE 7599 HOST_MACHINE_ARCH (optional) 7600 HOST_MACHINE_MACHINE (optional) 7601 HOST_TEXT_START_ADDR 7602 HOST_STACK_END_ADDR 7603 7604 in the file `../include/sys/h-XXX.h' (for your host). These values, 7605 plus the structures and macros defined in `a.out.h' on your host 7606 system, will produce a BFD target that will access ordinary a.out files 7607 on your host. To configure a new machine to use `host-aout.c', specify: 7608 7609 TDEFAULTS = -DDEFAULT_VECTOR=host_aout_big_vec 7610 TDEPFILES= host-aout.o trad-core.o 7611 7612 in the `config/XXX.mt' file, and modify `configure.in' to use the 7613 `XXX.mt' file (by setting "`bfd_target=XXX'") when your configuration 7614 is selected. 7615 7616 3.2.1 Relocations 7617 ----------------- 7618 7619 *Description* 7620 The file `aoutx.h' provides for both the _standard_ and _extended_ 7621 forms of a.out relocation records. 7622 7623 The standard records contain only an address, a symbol index, and a 7624 type field. The extended records (used on 29ks and sparcs) also have a 7625 full integer for an addend. 7626 7627 3.2.2 Internal entry points 7628 --------------------------- 7629 7630 *Description* 7631 `aoutx.h' exports several routines for accessing the contents of an 7632 a.out file, which are gathered and exported in turn by various format 7633 specific files (eg sunos.c). 7634 7635 3.2.2.1 `aout_SIZE_swap_exec_header_in' 7636 ....................................... 7637 7638 *Synopsis* 7639 void aout_SIZE_swap_exec_header_in, 7640 (bfd *abfd, 7641 struct external_exec *bytes, 7642 struct internal_exec *execp); 7643 *Description* 7644 Swap the information in an executable header RAW_BYTES taken from a raw 7645 byte stream memory image into the internal exec header structure EXECP. 7646 7647 3.2.2.2 `aout_SIZE_swap_exec_header_out' 7648 ........................................ 7649 7650 *Synopsis* 7651 void aout_SIZE_swap_exec_header_out 7652 (bfd *abfd, 7653 struct internal_exec *execp, 7654 struct external_exec *raw_bytes); 7655 *Description* 7656 Swap the information in an internal exec header structure EXECP into 7657 the buffer RAW_BYTES ready for writing to disk. 7658 7659 3.2.2.3 `aout_SIZE_some_aout_object_p' 7660 ...................................... 7661 7662 *Synopsis* 7663 const bfd_target *aout_SIZE_some_aout_object_p 7664 (bfd *abfd, 7665 struct internal_exec *execp, 7666 const bfd_target *(*callback_to_real_object_p) (bfd *)); 7667 *Description* 7668 Some a.out variant thinks that the file open in ABFD checking is an 7669 a.out file.

For example, The 88k bcs 7733 coff format is implemented in the file `coff-m88k.c'. This file 7734 `#include's `coff/m88k.h' which defines the external structure of the 7735 coff format for the 88k, and `coff/internal.h' which defines the 7736 internal structure. `coff-m88k.c' also defines the relocations used by 7737 the 88k format *Note Relocations::. 7738 7739 The Intel i960 processor version of coff is implemented in 7740 `coff-i960.c'. This file has the same structure as `coff-m88k.c', 7741 except that it includes `coff/i960.h' rather than `coff-m88k.h'. 7742 7743 3.3.1 Porting to a new version of coff 7744 -------------------------------------- 7745 7746 The recommended method is to select from the existing implementations 7747 the version of coff which is most like the one you want to use. For 7748 example, we'll say that i386 coff is the one you select, and that your 7749 coff flavour is called foo. Copy `i386coff.c' to `foocoff.c', copy 7750 `../include/coff/i386.h' to `../include/coff/foo.h', and add the lines 7751 to `targets.c' and `Makefile.in' so that your new back end is used. 7752 Alter the shapes of the structures in `../include/coff/foo.h' so that 7753 they match what you need. You will probably also have to add `#ifdef's 7754 to the code in `coff/internal.h' and `coffcode.h' if your version of 7755 coff is too wild. 7756 7757 You can verify that your new BFD backend works quite simply by 7758 building `objdump' from the `binutils' directory, and making sure that 7759 its version of what's going on and your host system's idea (assuming it 7760 has the pretty standard coff dump utility, usually called `att-dump' or 7761 just `dump') are the same. Then clean up your code, and send what 7762 you've done to Cygnus. Then your stuff will be in the next release, and 7763 you won't have to keep integrating it. 7764 7765 3.3.2 How the coff backend works 7766 -------------------------------- 7767 7768 3.3.2.1 File layout 7769 ................... 7770 7771 The Coff backend is split into generic routines that are applicable to 7772 any Coff target and routines that are specific to a particular target. 7773 The target-specific routines are further split into ones which are 7774 basically the same for all Coff targets except that they use the 7775 external symbol format or use different values for certain constants. 7776 7777 The generic routines are in `coffgen.c'. These routines work for 7778 any Coff target. They use some hooks into the target specific code; 7779 the hooks are in a `bfd_coff_backend_data' structure, one of which 7780 exists for each target. 7781 7782 The essentially similar target-specific routines are in 7783 `coffcode.h'. This header file includes executable C code. The 7784 various Coff targets first include the appropriate Coff header file, 7785 make any special defines that are needed, and then include `coffcode.h'. 7786 7787 Some of the Coff targets then also have additional routines in the 7788 target source file itself. 7789 7790 For example, `coff-i960.c' includes `coff/internal.h' and 7791 `coff/i960.h'. It then defines a few constants, such as `I960', and 7792 includes `coffcode.h'. Since the i960 has complex relocation types, 7793 `coff-i960.c' also includes some code to manipulate the i960 relocs. 7794 This code is not in `coffcode.h' because it would not be used by any 7795 other target. 7796 7797 3.3.2.2 Bit twiddling 7798 ..................... 7799 7800 Each flavour of coff supported in BFD has its own header file 7801 describing the external layout of the structures. There is also an 7802 internal description of the coff layout, in `coff/internal.h'. A major 7803 function of the coff backend is swapping the bytes and twiddling the 7804 bits to translate the external form of the structures into the normal 7805 internal form. This is all performed in the `bfd_swap'_thing_direction 7806 routines. Some elements are different sizes between different versions 7807 of coff; it is the duty of the coff version specific include file to 7808 override the definitions of various packing routines in `coffcode.h'. 7809 E.g., the size of line number entry in coff is sometimes 16 bits, and 7810 sometimes 32 bits. `#define'ing `PUT_LNSZ_LNNO' and `GET_LNSZ_LNNO' 7811 will select the correct one. No doubt, some day someone will find a 7812 version of coff which has a varying field size not catered to at the 7813 moment. To port BFD, that person will have to add more `#defines'. 7814 Three of the bit twiddling routines are exported to `gdb'; 7815 `coff_swap_aux_in', `coff_swap_sym_in' and `coff_swap_lineno_in'. `GDB' 7816 reads the symbol table on its own, but uses BFD to fix things up. More 7817 of the bit twiddlers are exported for `gas'; `coff_swap_aux_out', 7818 `coff_swap_sym_out', `coff_swap_lineno_out', `coff_swap_reloc_out', 7819 `coff_swap_filehdr_out', `coff_swap_aouthdr_out', 7820 `coff_swap_scnhdr_out'. `Gas' currently keeps track of all the symbol 7821 table and reloc drudgery itself, thereby saving the internal BFD 7822 overhead, but uses BFD to swap things on the way out, making cross 7823 ports much safer. Doing so also allows BFD (and thus the linker) to 7824 use the same header files as `gas', which makes one avenue to disaster 7825 disappear. 7826 7827 3.3.2.3 Symbol reading 7828 ...................... 7829 7830 The simple canonical form for symbols used by BFD is not rich enough to 7831 keep all the information available in a coff symbol table. The back end 7832 gets around this problem by keeping the original symbol table around, 7833 "behind the scenes". 7834 7835 When a symbol table is requested (through a call to 7836 `bfd_canonicalize_symtab'), a request gets through to 7837 `coff_get_normalized_symtab'. This reads the symbol table from the coff 7838 file and swaps all the structures inside into the internal form. It 7839 also fixes up all the pointers in the table (represented in the file by 7840 offsets from the first symbol in the table) into physical pointers to 7841 elements in the new internal table. This involves some work since the 7842 meanings of fields change depending upon context: a field that is a 7843 pointer to another structure in the symbol table at one moment may be 7844 the size in bytes of a structure at the next. Another pass is made 7845 over the table. All symbols which mark file names (`C_FILE' symbols) 7846 are modified so that the internal string points to the value in the 7847 auxent (the real filename) rather than the normal text associated with 7848 the symbol (`".file"'). 7849 7850 At this time the symbol names are moved around. Coff stores all 7851 symbols less than nine characters long physically within the symbol 7852 table; longer strings are kept at the end of the file in the string 7853 table. This pass moves all strings into memory and replaces them with 7854 pointers to the strings. 7855 7856 The symbol table is massaged once again, this time to create the 7857 canonical table used by the BFD application. Each symbol is inspected 7858 in turn, and a decision made (using the `sclass' field) about the 7859 various flags to set in the `asymbol'. *Note Symbols::. The generated 7860 canonical table shares strings with the hidden internal symbol table. 7861 7862 Any linenumbers are read from the coff file too, and attached to the 7863 symbols which own the functions the linenumbers belong to. 7864 7865 3.3.2.4 Symbol writing 7866 ...................... 7867 7868 Writing a symbol to a coff file which didn't come from a coff file will 7869 lose any debugging information. The `asymbol' structure remembers the 7870 BFD from which the symbol was taken, and on output the back end makes 7871 sure that the same destination target as source target is present. 7872 7873 When the symbols have come from a coff file then all the debugging 7874 information is preserved. 7875 7876 Symbol tables are provided for writing to the back end in a vector 7877 of pointers to pointers. This allows applications like the linker to 7878 accumulate and output large symbol tables without having to do too much 7879 byte copying. 7880 7881 This function runs through the provided symbol table and patches 7882 each symbol marked as a file place holder (`C_FILE') to point to the 7883 next file place holder in the list. It also marks each `offset' field 7884 in the list with the offset from the first symbol of the current symbol. 7885 7886 Another function of this procedure is to turn the canonical value 7887 form of BFD into the form used by coff. Internally, BFD expects symbol 7888 values to be offsets from a section base; so a symbol physically at 7889 0x120, but in a section starting at 0x100, would have the value 0x20. 7890 Coff expects symbols to contain their final value, so symbols have 7891 their values changed at this point to reflect their sum with their 7892 owning section. This transformation uses the `output_section' field of 7893 the `asymbol''s `asection' *Note Sections::. 7894 7895 * `coff_mangle_symbols' 7896 This routine runs though the provided symbol table and uses the 7897 offsets generated by the previous pass and the pointers generated when 7898 the symbol table was read in to create the structured hierarchy 7899 required by coff. It changes each pointer to a symbol into the index 7900 into the symbol table of the asymbol. 7901 7902 * `coff_write_symbols' 7903 This routine runs through the symbol table and patches up the 7904 symbols from their internal form into the coff way, calls the bit 7905 twiddlers, and writes out the table to the file. 7906 7907 3.3.2.5 `coff_symbol_type' 7908 .......................... 7909 7910 *Description* 7911 The hidden information for an `asymbol' is described in a 7912 `combined_entry_type': 7913 7914 7915 typedef struct coff_ptr_struct 7916 { 7917 /* Remembers the offset from the first symbol in the file for 7918 this symbol.

3.3.2.7 Writing relocations 8248 ........................... 8249 8250 To write relocations, the back end steps though the canonical 8251 relocation table and create an `internal_reloc'. The symbol index to 8252 use is removed from the `offset' field in the symbol table supplied. 8253 The address comes directly from the sum of the section base address and 8254 the relocation offset; the type is dug directly from the howto field. 8255 Then the `internal_reloc' is swapped into the shape of an 8256 `external_reloc' and written out to disk. 8257 8258 3.3.2.8 Reading linenumbers 8259 ........................... 8260 8261 Creating the linenumber table is done by reading in the entire coff 8262 linenumber table, and creating another table for internal use. 8263 8264 A coff linenumber table is structured so that each function is 8265 marked as having a line number of 0. Each line within the function is 8266 an offset from the first line in the function. The base of the line 8267 number information for the table is stored in the symbol associated 8268 with the function. 8269 8270 Note: The PE format uses line number 0 for a flag indicating a new 8271 source file. 8272 8273 The information is copied from the external to the internal table, 8274 and each symbol which marks a function is marked by pointing its... 8275 8276 How does this work ? 8277 8278 3.3.2.9 Reading relocations 8279 ........................... 8280 8281 Coff relocations are easily transformed into the internal BFD form 8282 (`arelent'). 8283 8284 Reading a coff relocation table is done in the following stages: 8285 8286 * Read the entire coff relocation table into memory. 8287 8288 * Process each relocation in turn; first swap it from the external 8289 to the internal form. 8290 8291 * Turn the symbol referenced in the relocation's symbol index into a 8292 pointer into the canonical symbol table. This table is the same 8293 as the one returned by a call to `bfd_canonicalize_symtab'. The 8294 back end will call that routine and save the result if a 8295 canonicalization hasn't been done. 8296 8297 * The reloc index is turned into a pointer to a howto structure, in 8298 a back end specific way. For instance, the 386 and 960 use the 8299 `r_type' to directly produce an index into a howto table vector; 8300 the 88k subtracts a number from the `r_type' field and creates an 8301 addend field. 8302 8303 8304 File: bfd.info, Node: elf, Next: mmo, Prev: coff, Up: BFD back ends 8305 8306 3.4 ELF backends 8307 ================ 8308 8309 BFD support for ELF formats is being worked on. Currently, the best 8310 supported back ends are for sparc and i386 (running svr4 or Solaris 2). 8311 8312 Documentation of the internals of the support code still needs to be 8313 written. The code is changing quickly enough that we haven't bothered 8314 yet. 8315 8316 3.4.0.1 `bfd_elf_find_section' 8317 .............................. 8318 8319 *Synopsis* 8320 struct elf_internal_shdr *bfd_elf_find_section (bfd *abfd, char *name); 8321 *Description* 8322 Helper functions for GDB to locate the string tables. Since BFD hides 8323 string tables from callers, GDB needs to use an internal hook to find 8324 them. Sun's .stabstr, in particular, isn't even pointed to by the 8325 .stab section, so ordinary mechanisms wouldn't work to find it, even if 8326 we had some. 8327 8328 8329 File: bfd.info, Node: mmo, Prev: elf, Up: BFD back ends 8330 8331 3.5 mmo backend 8332 =============== 8333 8334 The mmo object format is used exclusively together with Professor 8335 Donald E. Knuth's educational 64-bit processor MMIX. The simulator 8336 `mmix' which is available at 8337 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz' 8338 understands this format. That package also includes a combined 8339 assembler and linker called `mmixal'. The mmo format has no advantages 8340 feature-wise compared to e.g. ELF. It is a simple non-relocatable 8341 object format with no support for archives or debugging information, 8342 except for symbol value information and line numbers (which is not yet 8343 implemented in BFD). See 8344 `http://www-cs-faculty.stanford.edu/~knuth/mmix.html' for more 8345 information about MMIX. The ELF format is used for intermediate object 8346 files in the BFD implementation. 8347 8348 * Menu: 8349 8350 * File layout:: 8351 * Symbol-table:: 8352 * mmo section mapping:: 8353 8354 8355 File: bfd.info, Node: File layout, Next: Symbol-table, Prev: mmo, Up: mmo 8356 8357 3.5.1 File layout 8358 ----------------- 8359 8360 The mmo file contents is not partitioned into named sections as with 8361 e.g. ELF. Memory areas is formed by specifying the location of the 8362 data that follows. Only the memory area `0x0000...00' to `0x01ff...ff' 8363 is executable, so it is used for code (and constants) and the area 8364 `0x2000...00' to `0x20ff...ff' is used for writable data. *Note mmo 8365 section mapping::. 8366 8367 There is provision for specifying "special data" of 65536 different 8368 types. We use type 80 (decimal), arbitrarily chosen the same as the 8369 ELF `e_machine' number for MMIX, filling it with section information 8370 normally found in ELF objects. *Note mmo section mapping::. 8371 8372 Contents is entered as 32-bit words, xor:ed over previous contents, 8373 always zero-initialized. A word that starts with the byte `0x98' forms 8374 a command called a `lopcode', where the next byte distinguished between 8375 the thirteen lopcodes. The two remaining bytes, called the `Y' and `Z' 8376 fields, or the `YZ' field (a 16-bit big-endian number), are used for 8377 various purposes different for each lopcode. As documented in 8378 `http://www-cs-faculty.stanford.edu/~knuth/mmixal-intro.ps.gz', the 8379 lopcodes are: 8380 8381 `lop_quote' 8382 0x98000001. The next word is contents, regardless of whether it 8383 starts with 0x98 or not. 8384 8385 `lop_loc' 8386 0x9801YYZZ, where `Z' is 1 or 2. This is a location directive, 8387 setting the location for the next data to the next 32-bit word 8388 (for Z = 1) or 64-bit word (for Z = 2), plus Y * 2^56. Normally 8389 `Y' is 0 for the text segment and 2 for the data segment. 8390 8391 `lop_skip' 8392 0x9802YYZZ. Increase the current location by `YZ' bytes. 8393 8394 `lop_fixo' 8395 0x9803YYZZ, where `Z' is 1 or 2. Store the current location as 64 8396 bits into the location pointed to by the next 32-bit (Z = 1) or 8397 64-bit (Z = 2) word, plus Y * 2^56. 8398 8399 `lop_fixr' 8400 0x9804YYZZ. `YZ' is stored into the current location plus 2 - 4 * 8401 YZ. 8402 8403 `lop_fixrx' 8404 0x980500ZZ. `Z' is 16 or 24. A value `L' derived from the 8405 following 32-bit word are used in a manner similar to `YZ' in 8406 lop_fixr: it is xor:ed into the current location minus 4 * L. The 8407 first byte of the word is 0 or 1. If it is 1, then L = (LOWEST 24 8408 BITS OF WORD) - 2^Z, if 0, then L = (LOWEST 24 BITS OF WORD). 8409 8410 `lop_file' 8411 0x9806YYZZ. `Y' is the file number, `Z' is count of 32-bit words. 8412 Set the file number to `Y' and the line counter to 0. The next Z 8413 * 4 bytes contain the file name, padded with zeros if the count is 8414 not a multiple of four. The same `Y' may occur multiple times, 8415 but `Z' must be 0 for all but the first occurrence. 8416 8417 `lop_line' 8418 0x9807YYZZ. `YZ' is the line number. Together with lop_file, it 8419 forms the source location for the next 32-bit word. Note that for 8420 each non-lopcode 32-bit word, line numbers are assumed incremented 8421 by one. 8422 8423 `lop_spec' 8424 0x9808YYZZ. `YZ' is the type number. Data until the next lopcode 8425 other than lop_quote forms special data of type `YZ'. *Note mmo 8426 section mapping::. 8427 8428 Other types than 80, (or type 80 with a content that does not 8429 parse) is stored in sections named `.MMIX.spec_data.N' where N is 8430 the `YZ'-type. The flags for such a sections say not to allocate 8431 or load the data. The vma is 0. Contents of multiple occurrences 8432 of special data N is concatenated to the data of the previous 8433 lop_spec Ns. The location in data or code at which the lop_spec 8434 occurred is lost. 8435 8436 `lop_pre' 8437 0x980901ZZ. The first lopcode in a file. The `Z' field forms the 8438 length of header information in 32-bit words, where the first word 8439 tells the time in seconds since `00:00:00 GMT Jan 1 1970'. 8440 8441 `lop_post' 8442 0x980a00ZZ. Z > 32. This lopcode follows after all 8443 content-generating lopcodes in a program. The `Z' field denotes 8444 the value of `rG' at the beginning of the program. The following 8445 256 - Z big-endian 64-bit words are loaded into global registers 8446 `$G' ... `$255'. 8447 8448 `lop_stab' 8449 0x980b0000. The next-to-last lopcode in a program. Must follow 8450 immediately after the lop_post lopcode and its data. After this 8451 lopcode follows all symbols in a compressed format (*note 8452 Symbol-table::). 8453 8454 `lop_end' 8455 0x980cYYZZ. The last lopcode in a program. It must follow the 8456 lop_stab lopcode and its data. The `YZ' field contains the number 8457 of 32-bit words of symbol table information after the preceding 8458 lop_stab lopcode. 8459 8460 Note that the lopcode "fixups"; `lop_fixr', `lop_fixrx' and 8461 `lop_fixo' are not generated by BFD, but are handled. They are 8462 generated by `mmixal'. 8463 8464 This trivial one-label, one-instruction file: 8465 8466 :Main TRAP 1,2,3 8467 8468 can be represented this way in mmo: 8469 8470 0x98090101 - lop_pre, one 32-bit word with timestamp. 8471 <timestamp> 8472 0x98010002 - lop_loc, text segment, using a 64-bit address. 8473 Note that mmixal does not emit this for the file above. 8474 0x00000000 - Address, high 32 bits. 8475 0x00000000 - Address, low 32 bits. 8476 0x98060002 - lop_file, 2 32-bit words for file-name. 8477 0x74657374 - "test" 8478 0x2e730000 - ".s\0\0" 8479 0x98070001 - lop_line, line 1. 8480 0x00010203 - TRAP 1,2,3 8481 0x980a00ff - lop_post, setting $255 to 0. 8482 0x00000000 8483 0x00000000 8484 0x980b0000 - lop_stab for ":Main" = 0, serial 1. 8485 0x203a4040 *Note Symbol-table::. 8486 0x10404020 8487 0x4d206120 8488 0x69016e00 8489 0x81000000 8490 0x980c0005 - lop_end; symbol table contained five 32-bit words. 8491 8492 8493 File: bfd.info, Node: Symbol-table, Next: mmo section mapping, Prev: File layout, Up: mmo 8494 8495 3.5.2 Symbol table format 8496 ------------------------- 8497 8498 From mmixal.w (or really, the generated mmixal.tex) in 8499 `http://www-cs-faculty.stanford.edu/~knuth/programs/mmix.tar.gz'): 8500 "Symbols are stored and retrieved by means of a `ternary search trie', 8501 following ideas of Bentley and Sedgewick. (See ACM-SIAM Symp. on 8502 Discrete Algorithms `8' (1997), 360-369; R.Sedgewick, `Algorithms in C' 8503 (Reading, Mass. Addison-Wesley, 1998), `15.4'.) Each trie node stores 8504 a character, and there are branches to subtries for the cases where a 8505 given character is less than, equal to, or greater than the character 8506 in the trie. There also is a pointer to a symbol table entry if a 8507 symbol ends at the current node." 8508 8509 So it's a tree encoded as a stream of bytes. The stream of bytes 8510 acts on a single virtual global symbol, adding and removing characters 8511 and signalling complete symbol points. Here, we read the stream and 8512 create symbols at the completion points. 8513 8514 First, there's a control byte `m'. If any of the listed bits in `m' 8515 is nonzero, we execute what stands at the right, in the listed order: 8516 8517 (MMO3_LEFT) 8518 0x40 - Traverse left trie. 8519 (Read a new command byte and recurse.) 8520 8521 (MMO3_SYMBITS) 8522 0x2f - Read the next byte as a character and store it in the 8523 current character position; increment character position. 8524 Test the bits of `m': 8525 8526 (MMO3_WCHAR) 8527 0x80 - The character is 16-bit (so read another byte, 8528 merge into current character. 8529 8530 (MMO3_TYPEBITS) 8531 0xf - We have a complete symbol; parse the type, value 8532 and serial number and do what should be done 8533 with a symbol. The type and length information 8534 is in j = (m & 0xf). 8535 8536 (MMO3_REGQUAL_BITS) 8537 j == 0xf: A register variable. The following 8538 byte tells which register. 8539 j <= 8: An absolute symbol. Read j bytes as the 8540 big-endian number the symbol equals. 8541 A j = 2 with two zero bytes denotes an 8542 unknown symbol. 8543 j > 8: As with j <= 8, but add (0x20 << 56) 8544 to the value in the following j - 8 8545 bytes. 8546 8547 Then comes the serial number, as a variant of 8548 uleb128, but better named ubeb128: 8549 Read bytes and shift the previous value left 7 8550 (multiply by 128). Add in the new byte, repeat 8551 until a byte has bit 7 set. The serial number 8552 is the computed value minus 128. 8553 8554 (MMO3_MIDDLE) 8555 0x20 - Traverse middle trie. (Read a new command byte 8556 and recurse.) Decrement character position. 8557 8558 (MMO3_RIGHT) 8559 0x10 - Traverse right trie. (Read a new command byte and 8560 recurse.) 8561 8562 Let's look again at the `lop_stab' for the trivial file (*note File 8563 layout::). 8564 8565 0x980b0000 - lop_stab for ":Main" = 0, serial 1. 8566 0x203a4040 8567 0x10404020 8568 0x4d206120 8569 0x69016e00 8570 0x81000000 8571 8572 This forms the trivial trie (note that the path between ":" and "M" 8573 is redundant): 8574 8575 203a ":" 8576 40 / 8577 40 / 8578 10 \ 8579 40 / 8580 40 / 8581 204d "M" 8582 2061 "a" 8583 2069 "i" 8584 016e "n" is the last character in a full symbol, and 8585 with a value represented in one byte. 8586 00 The value is 0. 8587 81 The serial number is 1. 8588 8589 8590 File: bfd.info, Node: mmo section mapping, Prev: Symbol-table, Up: mmo 8591 8592 3.5.3 mmo section mapping 8593 ------------------------- 8594 8595 The implementation in BFD uses special data type 80 (decimal) to 8596 encapsulate and describe named sections, containing e.g. debug 8597 information. If needed, any datum in the encapsulation will be quoted 8598 using lop_quote. First comes a 32-bit word holding the number of 8599 32-bit words containing the zero-terminated zero-padded segment name. 8600 After the name there's a 32-bit word holding flags describing the 8601 section type. Then comes a 64-bit big-endian word with the section 8602 length (in bytes), then another with the section start address. 8603 Depending on the type of section, the contents might follow, 8604 zero-padded to 32-bit boundary. For a loadable section (such as data 8605 or code), the contents might follow at some later point, not 8606 necessarily immediately, as a lop_loc with the same start address as in 8607 the section description, followed by the contents. This in effect 8608 forms a descriptor that must be emitted before the actual contents. 8609 Sections described this way must not overlap. 8610 8611 For areas that don't have such descriptors, synthetic sections are 8612 formed by BFD. Consecutive contents in the two memory areas 8613 `0x0000...00' to `0x01ff...ff' and `0x2000...00' to `0x20ff...ff' are 8614 entered in sections named `.text' and `.data' respectively. If an area 8615 is not otherwise described, but would together with a neighboring lower 8616 area be less than `0x40000000' bytes long, it is joined with the lower 8617 area and the gap is zero-filled. For other cases, a new section is 8618 formed, named `.MMIX.sec.N'.

PREAMBLE 8692 8693 The purpose of this License is to make a manual, textbook, or other 8694 written document "free" in the sense of freedom: to assure everyone 8695 the effective freedom to copy and redistribute it, with or without 8696 modifying it, either commercially or noncommercially. Secondarily, 8697 this License preserves for the author and publisher a way to get 8698 credit for their work, while not being considered responsible for 8699 modifications made by others. 8700 8701 This License is a kind of "copyleft", which means that derivative 8702 works of the document must themselves be free in the same sense. 8703 It complements the GNU General Public License, which is a copyleft 8704 license designed for free software. 8705 8706 We have designed this License in order to use it for manuals for 8707 free software, because free software needs free documentation: a 8708 free program should come with manuals providing the same freedoms 8709 that the software does. But this License is not limited to 8710 software manuals; it can be used for any textual work, regardless 8711 of subject matter or whether it is published as a printed book. 8712 We recommend this License principally for works whose purpose is 8713 instruction or reference. 8714 8715 8716 1. APPLICABILITY AND DEFINITIONS 8717 8718 This License applies to any manual or other work that contains a 8719 notice placed by the copyright holder saying it can be distributed 8720 under the terms of this License. The "Document", below, refers to 8721 any such manual or work. Any member of the public is a licensee, 8722 and is addressed as "you." 8723 8724 A "Modified Version" of the Document means any work containing the 8725 Document or a portion of it, either copied verbatim, or with 8726 modifications and/or translated into another language. 8727 8728 A "Secondary Section" is a named appendix or a front-matter 8729 section of the Document that deals exclusively with the 8730 relationship of the publishers or authors of the Document to the 8731 Document's overall subject (or to related matters) and contains 8732 nothing that could fall directly within that overall subject. 8733 (For example, if the Document is in part a textbook of 8734 mathematics, a Secondary Section may not explain any mathematics.) 8735 The relationship could be a matter of historical connection with 8736 the subject or with related matters, or of legal, commercial, 8737 philosophical, ethical or political position regarding them. 8738 8739 The "Invariant Sections" are certain Secondary Sections whose 8740 titles are designated, as being those of Invariant Sections, in 8741 the notice that says that the Document is released under this 8742 License. 8743 8744 The "Cover Texts" are certain short passages of text that are 8745 listed, as Front-Cover Texts or Back-Cover Texts, in the notice 8746 that says that the Document is released under this License. 8747 8748 A "Transparent" copy of the Document means a machine-readable copy, 8749 represented in a format whose specification is available to the 8750 general public, whose contents can be viewed and edited directly 8751 and straightforwardly with generic text editors or (for images 8752 composed of pixels) generic paint programs or (for drawings) some 8753 widely available drawing editor, and that is suitable for input to 8754 text formatters or for automatic translation to a variety of 8755 formats suitable for input to text formatters. A copy made in an 8756 otherwise Transparent file format whose markup has been designed 8757 to thwart or discourage subsequent modification by readers is not 8758 Transparent. A copy that is not "Transparent" is called "Opaque." 8759 8760 Examples of suitable formats for Transparent copies include plain 8761 ASCII without markup, Texinfo input format, LaTeX input format, 8762 SGML or XML using a publicly available DTD, and 8763 standard-conforming simple HTML designed for human modification. 8764 Opaque formats include PostScript, PDF, proprietary formats that 8765 can be read and edited only by proprietary word processors, SGML 8766 or XML for which the DTD and/or processing tools are not generally 8767 available, and the machine-generated HTML produced by some word 8768 processors for output purposes only. 8769 8770 The "Title Page" means, for a printed book, the title page itself, 8771 plus such following pages as are needed to hold, legibly, the 8772 material this License requires to appear in the title page. For 8773 works in formats which do not have any title page as such, "Title 8774 Page" means the text near the most prominent appearance of the 8775 work's title, preceding the beginning of the body of the text. 8776 8777 2. VERBATIM COPYING 8778 8779 You may copy and distribute the Document in any medium, either 8780 commercially or noncommercially, provided that this License, the 8781 copyright notices, and the license notice saying this License 8782 applies to the Document are reproduced in all copies, and that you 8783 add no other conditions whatsoever to those of this License. You 8784 may not use technical measures to obstruct or control the reading 8785 or further copying of the copies you make or distribute. However, 8786 you may accept compensation in exchange for copies. If you 8787 distribute a large enough number of copies you must also follow 8788 the conditions in section 3. 8789 8790 You may also lend copies, under the same conditions stated above, 8791 and you may publicly display copies. 8792 8793 3. COPYING IN QUANTITY 8794 8795 If you publish printed copies of the Document numbering more than 8796 100, and the Document's license notice requires Cover Texts, you 8797 must enclose the copies in covers that carry, clearly and legibly, 8798 all these Cover Texts: Front-Cover Texts on the front cover, and 8799 Back-Cover Texts on the back cover. Both covers must also clearly 8800 and legibly identify you as the publisher of these copies. The 8801 front cover must present the full title with all words of the 8802 title equally prominent and visible. You may add other material 8803 on the covers in addition. Copying with changes limited to the 8804 covers, as long as they preserve the title of the Document and 8805 satisfy these conditions, can be treated as verbatim copying in 8806 other respects. 8807 8808 If the required texts for either cover are too voluminous to fit 8809 legibly, you should put the first ones listed (as many as fit 8810 reasonably) on the actual cover, and continue the rest onto 8811 adjacent pages. 8812 8813 If you publish or distribute Opaque copies of the Document 8814 numbering more than 100, you must either include a 8815 machine-readable Transparent copy along with each Opaque copy, or 8816 state in or with each Opaque copy a publicly-accessible 8817 computer-network location containing a complete Transparent copy 8818 of the Document, free of added material, which the general 8819 network-using public has access to download anonymously at no 8820 charge using public-standard network protocols. If you use the 8821 latter option, you must take reasonably prudent steps, when you 8822 begin distribution of Opaque copies in quantity, to ensure that 8823 this Transparent copy will remain thus accessible at the stated 8824 location until at least one year after the last time you 8825 distribute an Opaque copy (directly or through your agents or 8826 retailers) of that edition to the public. 8827 8828 It is requested, but not required, that you contact the authors of 8829 the Document well before redistributing any large number of 8830 copies, to give them a chance to provide you with an updated 8831 version of the Document. 8832 8833 4. MODIFICATIONS 8834 8835 You may copy and distribute a Modified Version of the Document 8836 under the conditions of sections 2 and 3 above, provided that you 8837 release the Modified Version under precisely this License, with 8838 the Modified Version filling the role of the Document, thus 8839 licensing distribution and modification of the Modified Version to 8840 whoever possesses a copy of it. In addition, you must do these 8841 things in the Modified Version: 8842 8843 A. Use in the Title Page (and on the covers, if any) a title 8844 distinct from that of the Document, and from those of previous 8845 versions (which should, if there were any, be listed in the 8846 History section of the Document). You may use the same title 8847 as a previous version if the original publisher of that version 8848 gives permission. 8849 B. List on the Title Page, as authors, one or more persons or 8850 entities responsible for authorship of the modifications in the 8851 Modified Version, together with at least five of the principal 8852 authors of the Document (all of its principal authors, if it 8853 has less than five). 8854 C. State on the Title page the name of the publisher of the 8855 Modified Version, as the publisher. 8856 D. Preserve all the copyright notices of the Document. 8857 E. Add an appropriate copyright notice for your modifications 8858 adjacent to the other copyright notices. 8859 F. Include, immediately after the copyright notices, a license 8860 notice giving the public permission to use the Modified Version 8861 under the terms of this License, in the form shown in the 8862 Addendum below. 8863 G. Preserve in that license notice the full lists of Invariant 8864 Sections and required Cover Texts given in the Document's 8865 license notice. 8866 H. Include an unaltered copy of this License. 8867 I. Preserve the section entitled "History", and its title, and add 8868 to it an item stating at least the title, year, new authors, and 8869 publisher of the Modified Version as given on the Title Page. 8870 If there is no section entitled "History" in the Document, 8871 create one stating the title, year, authors, and publisher of 8872 the Document as given on its Title Page, then add an item 8873 describing the Modified Version as stated in the previous 8874 sentence. 8875 J. Preserve the network location, if any, given in the Document for 8876 public access to a Transparent copy of the Document, and 8877 likewise the network locations given in the Document for 8878 previous versions it was based on. These may be placed in the 8879 "History" section. You may omit a network location for a work 8880 that was published at least four years before the Document 8881 itself, or if the original publisher of the version it refers 8882 to gives permission. 8883 K. In any section entitled "Acknowledgements" or "Dedications", 8884 preserve the section's title, and preserve in the section all the 8885 substance and tone of each of the contributor acknowledgements 8886 and/or dedications given therein. 8887 L. Preserve all the Invariant Sections of the Document, 8888 unaltered in their text and in their titles. Section numbers 8889 or the equivalent are not considered part of the section titles. 8890 M. Delete any section entitled "Endorsements." Such a section 8891 may not be included in the Modified Version. 8892 N. Do not retitle any existing section as "Endorsements" or to 8893 conflict in title with any Invariant Section. 8894 8895 If the Modified Version includes new front-matter sections or 8896 appendices that qualify as Secondary Sections and contain no 8897 material copied from the Document, you may at your option 8898 designate some or all of these sections as invariant. To do this, 8899 add their titles to the list of Invariant Sections in the Modified 8900 Version's license notice. These titles must be distinct from any 8901 other section titles. 8902 8903 You may add a section entitled "Endorsements", provided it contains 8904 nothing but endorsements of your Modified Version by various 8905 parties-for example, statements of peer review or that the text has 8906 been approved by an organization as the authoritative definition 8907 of a standard. 8908 8909 You may add a passage of up to five words as a Front-Cover Text, 8910 and a passage of up to 25 words as a Back-Cover Text, to the end 8911 of the list of Cover Texts in the Modified Version. Only one 8912 passage of Front-Cover Text and one of Back-Cover Text may be 8913 added by (or through arrangements made by) any one entity. If the 8914 Document already includes a cover text for the same cover, 8915 previously added by you or by arrangement made by the same entity 8916 you are acting on behalf of, you may not add another; but you may 8917 replace the old one, on explicit permission from the previous 8918 publisher that added the old one. 8919 8920 The author(s) and publisher(s) of the Document do not by this 8921 License give permission to use their names for publicity for or to 8922 assert or imply endorsement of any Modified Version. 8923 8924 5. COMBINING DOCUMENTS 8925 8926 You may combine the Document with other documents released under 8927 this License, under the terms defined in section 4 above for 8928 modified versions, provided that you include in the combination 8929 all of the Invariant Sections of all of the original documents, 8930 unmodified, and list them all as Invariant Sections of your 8931 combined work in its license notice. 8932 8933 The combined work need only contain one copy of this License, and 8934 multiple identical Invariant Sections may be replaced with a single 8935 copy. If there are multiple Invariant Sections with the same name 8936 but different contents, make the title of each such section unique 8937 by adding at the end of it, in parentheses, the name of the 8938 original author or publisher of that section if known, or else a 8939 unique number. Make the same adjustment to the section titles in 8940 the list of Invariant Sections in the license notice of the 8941 combined work. 8942 8943 In the combination, you must combine any sections entitled 8944 "History" in the various original documents, forming one section 8945 entitled "History"; likewise combine any sections entitled 8946 "Acknowledgements", and any sections entitled "Dedications." You 8947 must delete all sections entitled "Endorsements." 8948 8949 6. COLLECTIONS OF DOCUMENTS 8950 8951 You may make a collection consisting of the Document and other 8952 documents released under this License, and replace the individual 8953 copies of this License in the various documents with a single copy 8954 that is included in the collection, provided that you follow the 8955 rules of this License for verbatim copying of each of the 8956 documents in all other respects. 8957 8958 You may extract a single document from such a collection, and 8959 distribute it individually under this License, provided you insert 8960 a copy of this License into the extracted document, and follow 8961 this License in all other respects regarding verbatim copying of 8962 that document. 8963 8964 7. AGGREGATION WITH INDEPENDENT WORKS 8965 8966 A compilation of the Document or its derivatives with other 8967 separate and independent documents or works, in or on a volume of 8968 a storage or distribution medium, does not as a whole count as a 8969 Modified Version of the Document, provided no compilation 8970 copyright is claimed for the compilation. Such a compilation is 8971 called an "aggregate", and this License does not apply to the 8972 other self-contained works thus compiled with the Document, on 8973 account of their being thus compiled, if they are not themselves 8974 derivative works of the Document. 8975 8976 If the Cover Text requirement of section 3 is applicable to these 8977 copies of the Document, then if the Document is less than one 8978 quarter of the entire aggregate, the Document's Cover Texts may be 8979 placed on covers that surround only the Document within the 8980 aggregate. Otherwise they must appear on covers around the whole 8981 aggregate. 8982 8983 8. TRANSLATION 8984 8985 Translation is considered a kind of modification, so you may 8986 distribute translations of the Document under the terms of section 8987 4. Replacing Invariant Sections with translations requires special 8988 permission from their copyright holders, but you may include 8989 translations of some or all Invariant Sections in addition to the 8990 original versions of these Invariant Sections. You may include a 8991 translation of this License provided that you also include the 8992 original English version of this License. In case of a 8993 disagreement between the translation and the original English 8994 version of this License, the original English version will prevail. 8995 8996 9. TERMINATION 8997 8998 You may not copy, modify, sublicense, or distribute the Document 8999 except as expressly provided for under this License. Any other 9000 attempt to copy, modify, sublicense or distribute the Document is 9001 void, and will automatically terminate your rights under this 9002 License. However, parties who have received copies, or rights, 9003 from you under this License will not have their licenses 9004 terminated so long as such parties remain in full compliance. 9005 9006 10. FUTURE REVISIONS OF THIS LICENSE 9007 9008 The Free Software Foundation may publish new, revised versions of 9009 the GNU Free Documentation License from time to time. Such new 9010 versions will be similar in spirit to the present version, but may 9011 differ in detail to address new problems or concerns. See 9012 http://www.gnu.org/copyleft/. 9013 9014 Each version of the License is given a distinguishing version 9015 number. If the Document specifies that a particular numbered 9016 version of this License "or any later version" applies to it, you 9017 have the option of following the terms and conditions either of 9018 that specified version or of any later version that has been 9019 published (not as a draft) by the Free Software Foundation. If 9020 the Document does not specify a version number of this License, 9021 you may choose any version ever published (not as a draft) by the 9022 Free Software Foundation. 9023 9024 9025 ADDENDUM: How to use this License for your documents 9026 ==================================================== 9027 9028 To use this License in a document you have written, include a copy of 9029 the License in the document and put the following copyright and license 9030 notices just after the title page: 9031 9032 Copyright (C) YEAR YOUR NAME. 9033 Permission is granted to copy, distribute and/or modify this document 9034 under the terms of the GNU Free Documentation License, Version 1.1 9035 or any later version published by the Free Software Foundation; 9036 with the Invariant Sections being LIST THEIR TITLES, with the 9037 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. 9038 A copy of the license is included in the section entitled "GNU 9039 Free Documentation License." 9040 9041 If you have no Invariant Sections, write "with no Invariant Sections" 9042 instead of saying which ones are invariant. If you have no Front-Cover 9043 Texts, write "no Front-Cover Texts" instead of "Front-Cover Texts being 9044 LIST"; likewise for Back-Cover Texts. 9045 9046 If your document contains nontrivial examples of program code, we 9047 recommend releasing these examples in parallel under your choice of 9048 free software license, such as the GNU General Public License, to 9049 permit their use in free software. 9050 9051 9052 File: bfd.info, Node: BFD Index, Prev: GNU Free Documentation License, Up: Top 9053 9054 BFD Index 9055 ********* 9056 9057 [index] 9058 * Menu: 9059 9060 * _bfd_final_link_relocate: Relocating the section contents. 9061 (line 22) 9062 * _bfd_generic_link_add_archive_symbols: Adding symbols from an archive. 9063 (line 12) 9064 * _bfd_generic_link_add_one_symbol: Adding symbols from an object file. 9065 (line 19) 9066 * _bfd_generic_make_empty_symbol: symbol handling functions. 9067 (line 92) 9068 * _bfd_link_add_symbols in target vector: Adding Symbols to the Hash Table. 9069 (line 6) 9070 * _bfd_link_final_link in target vector: Performing the Final Link. 9071 (line 6) 9072 * _bfd_link_hash_table_create in target vector: Creating a Linker Hash Table. 9073 (line 6) 9074 * _bfd_relocate_contents: Relocating the section contents. 9075 (line 22) 9076 * aout_SIZE_machine_type: aout.
