One for - internal digestion, and one full of char arrays for I/O. The original - names have gone to detect errors. - - * Makefile.in, m68kcoff.c, targets.c - Test new structure code with a 68k coff implementaion - - * coff-code.h, icoff.c, coffswap.c, libcoff.h - Fixed all the places where there were problems with the size and - alignments of structures on disk and structures in memory. #ifed out - all the code in coffswap.c, since it should be done using the target - swap routines now. - -Thu May 9 11:00:45 1991 Steve Chamberlain (steve at cygint.cygnus.com) - - * ieee.c (do_one, ieee_slurp_section_data): now supports the load - multiple reloc command. - - * sunos.c (sunos4_set_section_contents): Made it so that sections - are always padded to their alignment size. - -Sat May 4 15:49:43 1991 John Gilmore (gnu at cygint.cygnus.com) - - * archive.c, bfd.c, coff-code.h, opncls.c, sunos.c, trad-core.c: - Clean up types and such (saber C problems). - * ecoff.c: Clean up types and such. Remove routines that are - not used. Fix up reading and swapping of shorts from files. - - Notes on bfd-0.5.2-patch1a, from Per Bothner: - - * a.out.vax.c: Remove two bogus "static" from prototypes. - - * ecoff.c: Got rid of lots of non-working junk (that had - been copied directly from coff-code.h). - Updated to be consistent with updates to icoff.c and coff-code.h. - - * libbfd.h: Added definitions for S_IXUSR, S_IXGRP, and S_IXOTH - if they're missing (as they are in (BDS-4.3-based) NewsOS-3). - - * sunos.c (n_txtoff): (Re-)Add support for sony. This is a kludge, - but until the target_vector is automatically generated, - it's as good as any. Note that the text offset is the only - difference between NewsOS and SunOs (including magic numbers). - (Most of the sunos_* routines should to renamed bsd_* - and move to a bsd.c file. Then (and when the target_vector - is automatically generated) it might make sense to create - a separate Sony target.) - - * sysdep.h: Don't declare fread and fwrite. Causes trouble - on some systems, and doesn't help on others. - Similarly, only define X_OK if not already defined. - - * trad-core.c: Don't include sys/stat.h - at least - on NewsOS 3, it has already been included. - -Tue Mar 5 01:47:57 1991 John Gilmore (gnu at cygint.cygnus.com) - - * coff-code.h (bfd_coff_swap_sym, bfd_coff_swap_aux, - bfd_coff_swap_lineno): Export the routines that byte-swap COFF - symbol tables if necessary when reading them in, so gdb can use - them. Add "bfd_coff_" to the names so they won't conflict with - names in calling programs. FIXME-soon: if coff-code.h is - included in two BFD modules, this will cause duplicate - definitions; the routines should be exported to a separate, - common, module (probably along with a mess of other ones). - -Sat Mar 2 12:11:26 1991 John Gilmore (gnu at cygint.cygnus.com) - - Improve modtime support. - - * bfd.h: Add boolean mtime_set, and declare bfd_get_mtime. - Remove #define for bfd_get_mtime. Remove gratuitous comment. - * bfd.c (bfd_get_mtime): New fn, caches mtime, gets if not cached. - BUG: archive members still do not get correct mod times. - - Improve floating point support for core files. - - * sunos.c (struct core): Change void *fpa_dummy to double fp_stuff. - (sunos4_core_file_p): Create a second registers section in the - core file, called ".reg2", for the float registers. - -Thu Feb 14 15:49:06 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com) - - * many changes to improve archive handling; found a logic flaw in - bfd_check_format which only just happened to work by cooncidence. - -Thu Feb 14 07:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com) - - * bfd.c (bfd_perform_relocation): fixed to use output_offsets - correctly. - - * bfd.h: changed type of udata in asymbol to void *, like it - should be. Added bfd_reloc_dangerous enum member. - - * coff-code.h: Fixed it so that internally generated symbols get - their values relocated correctly in all cases. Removed calls to - xmalloc. - - * icoff.c: Not understanding the destination symbol of a reloc is - not a failure any more, just 'dangerous'. This allows linking of - b.out and coff images. - - * sunos.c: Cleaned up the way that ZMAGIC section sizes are - calculated. - - -Tue Feb 12 13:25:46 1991 Steve Chamberlain (steve at cygint.cygnus.com) - - * sunos.c (translate_to_native_sym_flags): fixed - sym_pointer->n_value so that symbols on the way out get their - section relative values calculated correctly. - - * coff-code.h (mangle_symbols): fixed problem where tags were not - being relocated for structs, enums, unions. Also various lints. - -Mon Feb 11 19:52:26 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com) - - * archive.c (get_elt_at_filepos): system_call_error returned - incorrectly. - -Sun Feb 10 23:18:40 1991 Gumby Vinayak Wallace (gumby at cygint.cygnus.com) - - * Resolve the use of no_error and system_call_error. - The bfd library itself now will never set bfd_error to - no_error. - - The code still needs to be combed to make sure all the error - codes are correct. I suspect they are not always set correctly. - - * The names of all the messages have _ prepended because the sun - bundled compiler can't distinguish from a macro which takes an - argument and the same identifier in a non-macro context. - - * The reason for the above being that entry points which used to - be trampoline functions are now just macros which expand to a - direct call through the bfd's xfer vector. - - * (../include/intel-coff.h) F_AR32WR: fix this constant. Why - must gas have its own version of everything (the gas version - had the correct value) - -Tue Feb 5 11:46:53 1991 Steve Chamberlain (steve at cygint.cygnus.com) - - * b.out.c: Added patches supplied by chrisb@mipon2.intel.com to - properly support i960 architecture and output correct reloc stuff. - - * bfd.h: added prototype for bfd_printable_arch_mach, added - BFD_FAIL - - * coff-code.h: Applied patches from chrisb to support i960 - architecture, zero relocs and swap them correcly and conditionally - compiled the timestamp. - - * sunos.c: Made the default section alignment 2^3 so that doubles - are done properly.

Cygnus was providing GNU support for the team, and -was contracted to provide the required functionality. - - The name came from a conversation David Wallace was having with -Richard Stallman about the library: RMS said that it would be quite -hard--David said "BFD". Stallman was right, but the name stuck. - - At the same time, Ready Systems wanted much the same thing, but for -different object file formats: IEEE-695, Oasys, Srecords, a.out and 68k -coff. - - BFD was first implemented by members of Cygnus Support; Steve -Chamberlain (`sac@cygnus.com'), John Gilmore (`gnu@cygnus.com'), K. -Richard Pixley (`rich@cygnus.com') and David Henkel-Wallace -(`gumby@cygnus.com'). - - -File: bfd.info, Node: How It Works, Next: What BFD Version 2 Can Do, Prev: History, Up: Overview - -How To Use BFD -============== - - To use the library, include `bfd.h' and link with `libbfd.a'. - - BFD provides a common interface to the parts of an object file for a -calling application. - - When an application sucessfully opens a target file (object, -archive, or whatever), a pointer to an internal structure is returned. -This pointer points to a structure called `bfd', described in `bfd.h'. -Our convention is to call this pointer a BFD, and instances of it -within code `abfd'. All operations on the target object file are -applied as methods to the BFD. The mapping is defined within `bfd.h' -in a set of macros, all beginning with `bfd_' to reduce namespace -pollution. - - For example, this sequence does what you would probably expect: -return the number of sections in an object file attached to a BFD -`abfd'. - - #include "bfd.h" - - unsigned int number_of_sections(abfd) - bfd *abfd; - { - return bfd_count_sections(abfd); - } - - The abstraction used within BFD is that an object file has: - - * a header, - - * a number of sections containing raw data (*note Sections::.), - - * a set of relocations (*note Relocations::.), and - - * some symbol information (*note Symbols::.). - -Also, BFDs opened for archives have the additional attribute of an index -and contain subordinate BFDs. This approach is fine for a.out and coff, -but loses efficiency when applied to formats such as S-records and -IEEE-695. - - -File: bfd.info, Node: What BFD Version 2 Can Do, Prev: How It Works, Up: Overview - -What BFD Version 2 Can Do -========================= - - When an object file is opened, BFD subroutines automatically -determine the format of the input object file. They then build a -descriptor in memory with pointers to routines that will be used to -access elements of the object file's data structures. - - As different information from the the object files is required, BFD -reads from different sections of the file and processes them. For -example, a very common operation for the linker is processing symbol -tables. Each BFD back end provides a routine for converting between -the object file's representation of symbols and an internal canonical -format. When the linker asks for the symbol table of an object file, it -calls through a memory pointer to the routine from the relevant BFD -back end which reads and converts the table into a canonical form. The -linker then operates upon the canonical form. When the link is finished -and the linker writes the output file's symbol table, another BFD back -end routine is called to take the newly created symbol table and -convert it into the chosen output format. - -* Menu: - -* BFD information loss:: Information Loss -* Canonical format:: The BFD canonical object-file format - - -File: bfd.info, Node: BFD information loss, Next: Canonical format, Up: What BFD Version 2 Can Do - -Information Loss ----------------- - - *Information can be lost during output.* The output formats -supported by BFD do not provide identical facilities, and information -which can be described in one form has nowhere to go in another format. -One example of this is alignment information in `b.out'. There is -nowhere in an `a.out' format file to store alignment information on the -contained data, so when a file is linked from `b.out' and an `a.out' -image is produced, alignment information will not propagate to the -output file. (The linker will still use the alignment information -internally, so the link is performed correctly). - - Another example is COFF section names. COFF files may contain an -unlimited number of sections, each one with a textual section name. If -the target of the link is a format which does not have many sections -(e.g., `a.out') or has sections without names (e.g., the Oasys format), -the link cannot be done simply. You can circumvent this problem by -describing the desired input-to-output section mapping with the linker -command language. - - *Information can be lost during canonicalization.* The BFD internal -canonical form of the external formats is not exhaustive; there are -structures in input formats for which there is no direct representation -internally. This means that the BFD back ends cannot maintain all -possible data richness through the transformation between external to -internal and back to external formats. - - This limitation is only a problem when an application reads one -format and writes another. Each BFD back end is responsible for -maintaining as much data as possible, and the internal BFD canonical -form has structures which are opaque to the BFD core, and exported only -to the back ends. When a file is read in one format, the canonical form -is generated for BFD and the application. At the same time, the back -end saves away any information which may otherwise be lost. If the data -is then written back in the same format, the back end routine will be -able to use the canonical form provided by the BFD core as well as the -information it prepared earlier. Since there is a great deal of -commonality between back ends, there is no information lost when -linking or copying big endian COFF to little endian COFF, or `a.out' to -`b.out'. When a mixture of formats is linked, the information is only -lost from the files whose format differs from the destination. - - -File: bfd.info, Node: Canonical format, Prev: BFD information loss, Up: What BFD Version 2 Can Do - -The BFD canonical object-file format ------------------------------------- - - The greatest potential for loss of information occurs when there is -the least overlap between the information provided by the source -format, that stored by the canonical format, and that needed by the -destination format. A brief description of the canonical form may help -you understand which kinds of data you can count on preserving across -conversions. - -*files* - Information stored on a per-file basis includes target machine - architecture, particular implementation format type, a demand - pageable bit, and a write protected bit. Information like Unix - magic numbers is not stored here--only the magic numbers' meaning, - so a `ZMAGIC' file would have both the demand pageable bit and the - write protected text bit set. The byte order of the target is - stored on a per-file basis, so that big- and little-endian object - files may be used with one another. - -*sections* - Each section in the input file contains the name of the section, - the section's original address in the object file, size and - alignment information, various flags, and pointers into other BFD - data structures. - -*symbols* - Each symbol contains a pointer to the information for the object - file which originally defined it, its name, its value, and various - flag bits. When a BFD back end reads in a symbol table, it - relocates all symbols to make them relative to the base of the - section where they were defined. Doing this ensures that each - symbol points to its containing section. Each symbol also has a - varying amount of hidden private data for the BFD back end. Since - the symbol points to the original file, the private data format - for that symbol is accessible. `ld' can operate on a collection - of symbols of wildly different formats without problems. - - Normal global and simple local symbols are maintained on output, - so an output file (no matter its format) will retain symbols - pointing to functions and to global, static, and common variables. - Some symbol information is not worth retaining; in `a.out', type - information is stored in the symbol table as long symbol names. - This information would be useless to most COFF debuggers; the - linker has command line switches to allow users to throw it away. - - There is one word of type information within the symbol, so if the - format supports symbol type information within symbols (for - example, COFF, IEEE, Oasys) and the type is simple enough to fit - within one word (nearly everything but aggregates), the - information will be preserved. - -*relocation level* - Each canonical BFD relocation record contains a pointer to the - symbol to relocate to, the offset of the data to relocate, the - section the data is in, and a pointer to a relocation type - descriptor. Relocation is performed by passing messages through - the relocation type descriptor and the symbol pointer. Therefore, - relocations can be performed on output data using a relocation - method that is only available in one of the input formats. For - instance, Oasys provides a byte relocation format. A relocation - record requesting this relocation type would point indirectly to a - routine to perform this, so the relocation may be performed on a - byte being written to a 68k COFF file, even though 68k COFF has no - such relocation type. - -*line numbers* - Object formats can contain, for debugging purposes, some form of - mapping between symbols, source line numbers, and addresses in the - output file. These addresses have to be relocated along with the - symbol information. Each symbol with an associated list of line - number records points to the first record of the list. The head - of a line number list consists of a pointer to the symbol, which - allows finding out the address of the function whose line number - is being described. The rest of the list is made up of pairs: - offsets into the section and line numbers. Any format which can - simply derive this information can pass it successfully between - formats (COFF, IEEE and Oasys). - - -File: bfd.info, Node: BFD front end, Next: BFD back ends, Prev: Overview, Up: Top - -BFD front end -************* - -`typedef bfd' -============= - - A BFD has type `bfd'; objects of this type are the cornerstone of -any application using BFD.

There is one -obstack per open BFD file, into which the current state is stored. When -a BFD is closed, the obstack is deleted, and so everything which has -been allocated by BFD for the closing file is thrown away. - - BFD does not free anything created by an application, but pointers -into `bfd' structures become invalid on a `bfd_close'; for example, -after a `bfd_close' the vector passed to `bfd_canonicalize_symtab' is -still around, since it has been allocated by the application, but the -data that it pointed to are lost. - - The general rule is to not close a BFD until all operations dependent -upon data from the BFD have been completed, or all the data from within -the file has been copied. To help with the management of memory, there -is a function (`bfd_alloc_size') which returns the number of bytes in -obstacks associated with the supplied BFD. This could be used to select -the greediest open BFD, close it to reclaim the memory, perform some -operation and reopen the BFD again, to get a fresh copy of the data -structures. - - -File: bfd.info, Node: Initialization, Next: Sections, Prev: Memory Usage, Up: BFD front end - -Initialization -============== - - These are the functions that handle initializing a BFD. -`bfd_init' -.......... - -*Synopsis* - void bfd_init(void); - *Description* -This routine must be called before any other BFD function to initialize -magical internal data structures. - -File: bfd.info, Node: Sections, Next: Symbols, Prev: Initialization, Up: BFD front end - -Sections -======== - -The raw data contained within a BFD is maintained through the section -abstraction. A single BFD may have any number of sections. It keeps -hold of them by pointing to the first; each one points to the next in -the list. - - Sections are supported in BFD in `section.c'. - -* Menu: - -* Section Input:: -* Section Output:: -* typedef asection:: -* section prototypes:: - - -File: bfd.info, Node: Section Input, Next: Section Output, Prev: Sections, Up: Sections - -Section input -------------- - -When a BFD is opened for reading, the section structures are created -and attached to the BFD. - - Each section has a name which describes the section in the outside -world--for example, `a.out' would contain at least three sections, -called `.text', `.data' and `.bss'. - - Names need not be unique; for example a COFF file may have several -sections named `.data'. - - Sometimes a BFD will contain more than the "natural" number of -sections. A back end may attach other sections containing constructor -data, or an application may add a section (using `bfd_make_section') to -the sections attached to an already open BFD. For example, the linker -creates an extra section `COMMON' for each input file's BFD to hold -information about common storage. - - The raw data is not necessarily read in when the section descriptor -is created. Some targets may leave the data in place until a -`bfd_get_section_contents' call is made. Other back ends may read in -all the data at once. For example, an S-record file has to be read -once to determine the size of the data. An IEEE-695 file doesn't -contain raw data in sections, but data and relocation expressions -intermixed, so the data area has to be parsed to get out the data and -relocations. - -File: bfd.info, Node: Section Output, Next: typedef asection, Prev: Section Input, Up: Sections - -Section output --------------- - -To write a new object style BFD, the various sections to be written -have to be created. They are attached to the BFD in the same way as -input sections; data is written to the sections using -`bfd_set_section_contents'. - - Any program that creates or combines sections (e.g., the assembler -and linker) must use the `asection' fields `output_section' and -`output_offset' to indicate the file sections to which each section -must be written. (If the section is being created from scratch, -`output_section' should probably point to the section itself and -`output_offset' should probably be zero.) - - The data to be written comes from input sections attached (via -`output_section' pointers) to the output sections. The output section -structure can be considered a filter for the input section: the output -section determines the vma of the output data and the name, but the -input section determines the offset into the output section of the data -to be written. - - E.g., to create a section "O", starting at 0x100, 0x123 long, -containing two subsections, "A" at offset 0x0 (i.e., at vma 0x100) and -"B" at offset 0x20 (i.e., at vma 0x120) the `asection' structures would -look like: - - section name "A" - output_offset 0x00 - size 0x20 - output_section -----------> section name "O" - | vma 0x100 - section name "B" | size 0x123 - output_offset 0x20 | - size 0x103 | - output_section --------| - -Link orders ------------ - -The data within a section is stored in a "link_order". These are much -like the fixups in `gas'. The link_order abstraction allows a section -to grow and shrink within itself. - - A link_order knows how big it is, and which is the next link_order -and where the raw data for it is; it also points to a list of -relocations which apply to it. - - The link_order is used by the linker to perform relaxing on final -code. The compiler creates code which is as big as necessary to make -it work without relaxing, and the user can select whether to relax. -Sometimes relaxing takes a lot of time. The linker runs around the -relocations to see if any are attached to data which can be shrunk, if -so it does it on a link_order by link_order basis. - -File: bfd.info, Node: typedef asection, Next: section prototypes, Prev: Section Output, Up: Sections - -typedef asection ----------------- - -Here is the section structure: -. - typedef struct sec - { - /* The name of the section; the name isn't a copy, the pointer is - the same as that passed to bfd_make_section. */ - - CONST char *name; - - /* Which section is it; 0..nth. */ - - int index; - - /* The next section in the list belonging to the BFD, or NULL. */ - - struct sec *next; - - /* The field flags contains attributes of the section.

BFD passes information to -applications though the `asymbol' structure. When the application -requests the symbol table, BFD reads the table in the native form and -translates parts of it into the internal format. To maintain more than -the information passed to applications, some targets keep some -information "behind the scenes" in a structure only the particular back -end knows about. For example, the coff back end keeps the original -symbol table structure as well as the canonical structure when a BFD is -read in. On output, the coff back end can reconstruct the output symbol -table so that no information is lost, even information unique to coff -which BFD doesn't know or understand. If a coff symbol table were read, -but were written through an a.out back end, all the coff specific -information would be lost. The symbol table of a BFD is not necessarily -read in until a canonicalize request is made. Then the BFD back end -fills in a table provided by the application with pointers to the -canonical information. To output symbols, the application provides BFD -with a table of pointers to pointers to `asymbol's. This allows -applications like the linker to output a symbol as it was read, since -the "behind the scenes" information will be still available. - -* Menu: - -* Reading Symbols:: -* Writing Symbols:: -* Mini Symbols:: -* typedef asymbol:: -* symbol handling functions:: - - -File: bfd.info, Node: Reading Symbols, Next: Writing Symbols, Prev: Symbols, Up: Symbols - -Reading symbols ---------------- - -There are two stages to reading a symbol table from a BFD: allocating -storage, and the actual reading process.

The application attaches a vector of pointers to pointers to -symbols to the BFD being written, and fills in the symbol count. The -close and cleanup code reads through the table provided and performs -all the necessary operations. The BFD output code must always be -provided with an "owned" symbol: one which has come from another BFD, -or one which has been created using `bfd_make_empty_symbol'. Here is an -example showing the creation of a symbol table with only one element: - - #include "bfd.h" - main() - { - bfd *abfd; - asymbol *ptrs[2]; - asymbol *new; - - abfd = bfd_openw("foo","a.out-sunos-big"); - bfd_set_format(abfd, bfd_object); - new = bfd_make_empty_symbol(abfd); - new->name = "dummy_symbol"; - new->section = bfd_make_section_old_way(abfd, ".text"); - new->flags = BSF_GLOBAL; - new->value = 0x12345; - - ptrs[0] = new; - ptrs[1] = (asymbol *)0; - - bfd_set_symtab(abfd, ptrs, 1); - bfd_close(abfd); - } - - ./makesym - nm foo - 00012345 A dummy_symbol - - Many formats cannot represent arbitary symbol information; for -instance, the `a.out' object format does not allow an arbitary number -of sections.

It has a symbol table, -although there's not much a user program will do with it. - - The big difference between an archive BFD and an ordinary BFD is -that the archive doesn't have sections. Instead it has a chain of BFDs -that are considered its contents. These BFDs can be manipulated like -any other. The BFDs contained in an archive opened for reading will -all be opened for reading. You may put either input or output BFDs -into an archive opened for output; they will be handled correctly when -the archive is closed. - - Use `bfd_openr_next_archived_file' to step through the contents of -an archive opened for input. You don't have to read the entire archive -if you don't want to! Read it until you find what you want. - - Archive contents of output BFDs are chained through the `next' -pointer in a BFD. The first one is findable through the `archive_head' -slot of the archive. Set it with `bfd_set_archive_head' (q.v.). A -given BFD may be in only one open output archive at a time. - - As expected, the BFD archive code is more general than the archive -code of any given environment. BFD archives may contain files of -different formats (e.g., a.out and coff) and even different -architectures. You may even place archives recursively into archives! - - This can cause unexpected confusion, since some archive formats are -more expressive than others. For instance, Intel COFF archives can -preserve long filenames; SunOS a.out archives cannot. If you move a -file from the first to the second format and back again, the filename -may be truncated. Likewise, different a.out environments have different -conventions as to how they truncate filenames, whether they preserve -directory names in filenames, etc. When interoperating with native -tools, be sure your files are homogeneous. - - Beware: most of these formats do not react well to the presence of -spaces in filenames. We do the best we can, but can't always handle -this case due to restrictions in the format of archives. Many Unix -utilities are braindead in regards to spaces and such in filenames -anyway, so this shouldn't be much of a restriction. - - Archives are supported in BFD in `archive.c'. -`bfd_get_next_mapent' -..................... - -*Synopsis* - symindex bfd_get_next_mapent(bfd *abfd, symindex previous, carsym **sym); - *Description* -Step through archive ABFD's symbol table (if it has one).

It is the pointer into -the table returned by the back end's `get_symtab' action. *Note -Symbols::. The symbol is referenced through a pointer to a pointer so -that tools like the linker can fix up all the symbols of the same name -by modifying only one pointer. The relocation routine looks in the -symbol and uses the base of the section the symbol is attached to and -the value of the symbol as the initial relocation offset. If the symbol -pointer is zero, then the section provided is looked up. - - * `address' The `address' field gives the offset in bytes from the -base of the section data which owns the relocation record to the first -byte of relocatable information. The actual data relocated will be -relative to this point; for example, a relocation type which modifies -the bottom two bytes of a four byte word would not touch the first byte -pointed to in a big endian world. - - * `addend' The `addend' is a value provided by the back end to be -added (!) to the relocation offset. Its interpretation is dependent upon -the howto. For example, on the 68k the code: - - char foo[]; - main() - { - return foo[0x12345678]; - } - - Could be compiled into: - - linkw fp,#-4 - moveb @#12345678,d0 - extbl d0 - unlk fp - rts - - This could create a reloc pointing to `foo', but leave the offset in -the data, something like: - - RELOCATION RECORDS FOR [.text]: - offset type value - 00000006 32 _foo - - 00000000 4e56 fffc ; linkw fp,#-4 - 00000004 1039 1234 5678 ; moveb @#12345678,d0 - 0000000a 49c0 ; extbl d0 - 0000000c 4e5e ; unlk fp - 0000000e 4e75 ; rts - - Using coff and an 88k, some instructions don't have enough space in -them to represent the full address range, and pointers have to be -loaded in two parts. So you'd get something like: - - or.u r13,r0,hi16(_foo+0x12345678) - ld.b r2,r13,lo16(_foo+0x12345678) - jmp r1 - - This should create two relocs, both pointing to `_foo', and with -0x12340000 in their addend field. The data would consist of: - - RELOCATION RECORDS FOR [.text]: - offset type value - 00000002 HVRT16 _foo+0x12340000 - 00000006 LVRT16 _foo+0x12340000 - - 00000000 5da05678 ; or.u r13,r0,0x5678 - 00000004 1c4d5678 ; ld.b r2,r13,0x5678 - 00000008 f400c001 ; jmp r1 - - The relocation routine digs out the value from the data, adds it to -the addend to get the original offset, and then adds the value of -`_foo'. Note that all 32 bits have to be kept around somewhere, to cope -with carry from bit 15 to bit 16. - - One further example is the sparc and the a.out format. The sparc has -a similar problem to the 88k, in that some instructions don't have room -for an entire offset, but on the sparc the parts are created in odd -sized lumps. The designers of the a.out format chose to not use the -data within the section for storing part of the offset; all the offset -is kept within the reloc. Anything in the data should be ignored. - - save %sp,-112,%sp - sethi %hi(_foo+0x12345678),%g2 - ldsb [%g2+%lo(_foo+0x12345678)],%i0 - ret - restore - - Both relocs contain a pointer to `foo', and the offsets contain junk. - - RELOCATION RECORDS FOR [.text]: - offset type value - 00000004 HI22 _foo+0x12345678 - 00000008 LO10 _foo+0x12345678 - - 00000000 9de3bf90 ; save %sp,-112,%sp - 00000004 05000000 ; sethi %hi(_foo+0),%g2 - 00000008 f048a000 ; ldsb [%g2+%lo(_foo+0)],%i0 - 0000000c 81c7e008 ; ret - 00000010 81e80000 ; restore - - * `howto' The `howto' field can be imagined as a relocation -instruction. It is a pointer to a structure which contains information -on what to do with all of the other information in the reloc record and -data section. A back end would normally have a relocation instruction -set and turn relocations into pointers to the correct structure on -input - but it would be possible to create each howto field on demand. -`enum complain_overflow' -........................ - -Indicates what sort of overflow checking should be done when performing -a relocation. -. - enum complain_overflow - { - /* Do not complain on overflow. */ - complain_overflow_dont, - - /* Complain if the bitfield overflows, whether it is considered - as signed or unsigned. */ - complain_overflow_bitfield, - - /* Complain if the value overflows when considered as signed - number. */ - complain_overflow_signed, - - /* Complain if the value overflows when considered as an - unsigned number. */ - complain_overflow_unsigned - }; - -`reloc_howto_type' -.................. - - The `reloc_howto_type' is a structure which contains all the -information that libbfd needs to know to tie up a back end's data. -.struct symbol_cache_entry; /* Forward declaration */ - - struct reloc_howto_struct - { - /* The type field has mainly a documentary use - the back end can - do what it wants with it, though normally the back end's - external idea of what a reloc number is stored - in this field.

All the back end provides to the root part of BFD is a -structure containing pointers to functions which perform certain low -level operations on files. BFD translates the applications's requests -through a pointer into calls to the back end routines. - - When a file is opened with `bfd_openr', its format and target are -unknown. BFD uses various mechanisms to determine how to interpret the -file. The operations performed are: - - * Create a BFD by calling the internal routine `_bfd_new_bfd', then - call `bfd_find_target' with the target string supplied to - `bfd_openr' and the new BFD pointer. - - * If a null target string was provided to `bfd_find_target', look up - the environment variable `GNUTARGET' and use that as the target - string. - - * If the target string is still `NULL', or the target string is - `default', then use the first item in the target vector as the - target type, and set `target_defaulted' in the BFD to cause - `bfd_check_format' to loop through all the targets. *Note - bfd_target::. *Note Formats::. - - * Otherwise, inspect the elements in the target vector one by one, - until a match on target name is found. When found, use it. - - * Otherwise return the error `bfd_error_invalid_target' to - `bfd_openr'. - - * `bfd_openr' attempts to open the file using `bfd_open_file', and - returns the BFD. Once the BFD has been opened and the target -selected, the file format may be determined. This is done by calling -`bfd_check_format' on the BFD with a suggested format. If -`target_defaulted' has been set, each possible target type is tried to -see if it recognizes the specified format. `bfd_check_format' returns -`true' when the caller guesses right. - -* Menu: - -* bfd_target:: - - -File: bfd.info, Node: bfd_target, Prev: Targets, Up: Targets - -bfd_target ----------- - -*Description* -This structure contains everything that BFD knows about a target. It -includes things like its byte order, name, and which routines to call -to do various operations. - - Every BFD points to a target structure with its `xvec' member. - - The macros below are used to dispatch to functions through the -`bfd_target' vector. They are used in a number of macros further down -in `bfd.h', and are also used when calling various routines by hand -inside the BFD implementation.

The third routine takes all the object files and links them -together to create the output file. These routines are designed so -that the linker proper does not need to know anything about the symbols -in the object files that it is linking. The linker merely arranges the -sections as directed by the linker script and lets BFD handle the -details of symbols and relocs. - - The second routine and third routines are passed a pointer to a -`struct bfd_link_info' structure (defined in `bfdlink.h') which holds -information relevant to the link, including the linker hash table -(which was created by the first routine) and a set of callback -functions to the linker proper. - - The generic linker routines are in `linker.c', and use the header -file `genlink.h'. As of this writing, the only back ends which have -implemented versions of these routines are a.out (in `aoutx.h') and -ECOFF (in `ecoff.c'). The a.out routines are used as examples -throughout this section. - -* Menu: - -* Creating a Linker Hash Table:: -* Adding Symbols to the Hash Table:: -* Performing the Final Link:: - - -File: bfd.info, Node: Creating a Linker Hash Table, Next: Adding Symbols to the Hash Table, Prev: Linker Functions, Up: Linker Functions - -Creating a linker hash table ----------------------------- - -The linker routines must create a hash table, which must be derived -from `struct bfd_link_hash_table' described in `bfdlink.c'. *Note Hash -Tables:: for information on how to create a derived hash table.

If the back end does -not require any additional information to be stored with the entries in -the hash table, the entry point may simply create a `struct -bfd_link_hash_table'. Most likely, however, some additional -information will be needed. - - For example, with each entry in the hash table the a.out linker -keeps the index the symbol has in the final output file (this index -number is used so that when doing a relocateable link the symbol index -used in the output file can be quickly filled in when copying over a -reloc). The a.out linker code defines the required structures and -functions for a hash table derived from `struct bfd_link_hash_table'. -The a.out linker hash table is created by the function -`NAME(aout,link_hash_table_create)'; it simply allocates space for the -hash table, initializes it, and returns a pointer to it. - - When writing the linker routines for a new back end, you will -generally not know exactly which fields will be required until you have -finished. You should simply create a new hash table which defines no -additional fields, and then simply add fields as they become necessary. - -File: bfd.info, Node: Adding Symbols to the Hash Table, Next: Performing the Final Link, Prev: Creating a Linker Hash Table, Up: Linker Functions - -Adding symbols to the hash table --------------------------------- - -The linker proper will call the `_bfd_link_add_symbols' entry point for -each object file or archive which is to be linked (typically these are -the files named on the command line, but some may also come from the -linker script). The entry point is responsible for examining the file. -For an object file, BFD must add any relevant symbol information to -the hash table. For an archive, BFD must determine which elements of -the archive should be used and adding them to the link. - - The a.out version of this entry point is -`NAME(aout,link_add_symbols)'. - -* Menu: - -* Differing file formats:: -* Adding symbols from an object file:: -* Adding symbols from an archive:: - - -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 - -Differing file formats -...................... - -Normally all the files involved in a link will be of the same format, -but it is also possible to link together different format object files, -and the back end must support that. The `_bfd_link_add_symbols' entry -point is called via the target vector of the file to be added. This -has an important consequence: the function may not assume that the hash -table is the type created by the corresponding -`_bfd_link_hash_table_create' vector. All the `_bfd_link_add_symbols' -function can assume about the hash table is that it is derived from -`struct bfd_link_hash_table'. - - Sometimes the `_bfd_link_add_symbols' function must store some -information in the hash table entry to be used by the `_bfd_final_link' -function. In such a case the `creator' field of the hash table must be -checked to make sure that the hash table was created by an object file -of the same format. - - The `_bfd_final_link' routine must be prepared to handle a hash -entry without any extra information added by the -`_bfd_link_add_symbols' function. A hash entry without extra -information will also occur when the linker script directs the linker -to create a symbol. Note that, regardless of how a hash table entry is -added, all the fields will be initialized to some sort of null value by -the hash table entry initialization function. - - See `ecoff_link_add_externals' for an example of how to check the -`creator' field before saving information (in this case, the ECOFF -external symbol debugging information) in a hash table entry. - -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 - -Adding symbols from an object file -.................................. - -When the `_bfd_link_add_symbols' routine is passed an object file, it -must add all externally visible symbols in that object file to the hash -table. The actual work of adding the symbol to the hash table is -normally handled by the function `_bfd_generic_link_add_one_symbol'. -The `_bfd_link_add_symbols' routine is responsible for reading all the -symbols from the object file and passing the correct information to -`_bfd_generic_link_add_one_symbol'. - - The `_bfd_link_add_symbols' routine should not use -`bfd_canonicalize_symtab' to read the symbols. The point of providing -this routine is to avoid the overhead of converting the symbols into -generic `asymbol' structures. - - `_bfd_generic_link_add_one_symbol' handles the details of combining -common symbols, warning about multiple definitions, and so forth. It -takes arguments which describe the symbol to add, notably symbol flags, -a section, and an offset. The symbol flags include such things as -`BSF_WEAK' or `BSF_INDIRECT'. The section is a section in the object -file, or something like `bfd_und_section_ptr' for an undefined symbol -or `bfd_com_section_ptr' for a common symbol. - - If the `_bfd_final_link' routine is also going to need to read the -symbol information, the `_bfd_link_add_symbols' routine should save it -somewhere attached to the object file BFD. However, the information -should only be saved if the `keep_memory' field of the `info' argument -is true, so that the `-no-keep-memory' linker switch is effective. - - The a.out function which adds symbols from an object file is -`aout_link_add_object_symbols', and most of the interesting work is in -`aout_link_add_symbols'. The latter saves pointers to the hash tables -entries created by `_bfd_generic_link_add_one_symbol' indexed by symbol -number, so that the `_bfd_final_link' routine does not have to call the -hash table lookup routine to locate the entry. - -File: bfd.info, Node: Adding symbols from an archive, Prev: Adding symbols from an object file, Up: Adding Symbols to the Hash Table - -Adding symbols from an archive -.............................. - -When the `_bfd_link_add_symbols' routine is passed an archive, it must -look through the symbols defined by the archive and decide which -elements of the archive should be included in the link. For each such -element it must call the `add_archive_element' linker callback, and it -must add the symbols from the object file to the linker hash table. - - In most cases the work of looking through the symbols in the archive -should be done by the `_bfd_generic_link_add_archive_symbols' function. -This function builds a hash table from the archive symbol table and -looks through the list of undefined symbols to see which elements -should be included. `_bfd_generic_link_add_archive_symbols' is passed -a function to call to make the final decision about adding an archive -element to the link and to do the actual work of adding the symbols to -the linker hash table. - - The function passed to `_bfd_generic_link_add_archive_symbols' must -read the symbols of the archive element and decide whether the archive -element should be included in the link. If the element is to be -included, the `add_archive_element' linker callback routine must be -called with the element as an argument, and the elements symbols must -be added to the linker hash table just as though the element had itself -been passed to the `_bfd_link_add_symbols' function. - - When the a.out `_bfd_link_add_symbols' function receives an archive, -it calls `_bfd_generic_link_add_archive_symbols' passing -`aout_link_check_archive_element' as the function argument. -`aout_link_check_archive_element' calls `aout_link_check_ar_symbols'. -If the latter decides to add the element (an element is only added if -it provides a real, non-common, definition for a previously undefined -or common symbol) it calls the `add_archive_element' callback and then -`aout_link_check_archive_element' calls `aout_link_add_symbols' to -actually add the symbols to the linker hash table. - - The ECOFF back end is unusual in that it does not normally call -`_bfd_generic_link_add_archive_symbols', because ECOFF archives already -contain a hash table of symbols.

It is for a large set of -hosts that use "more or less standard" a.out files, and for which -cross-debugging is not interesting. It uses the standard 32-bit a.out -support routines, but determines the file offsets and addresses of the -text, data, and BSS sections, the machine architecture and machine -type, and the entry point address, in a host-dependent manner.

The major -differences between formats are the sizes and alignments of fields in -structures on disk, and the occasional extra field. - - Coff in all its varieties is implemented with a few common files and -a number of implementation specific files. For example, The 88k bcs -coff format is implemented in the file `coff-m88k.c'. This file -`#include's `coff/m88k.h' which defines the external structure of the -coff format for the 88k, and `coff/internal.h' which defines the -internal structure. `coff-m88k.c' also defines the relocations used by -the 88k format *Note Relocations::. - - The Intel i960 processor version of coff is implemented in -`coff-i960.c'. This file has the same structure as `coff-m88k.c', -except that it includes `coff/i960.h' rather than `coff-m88k.h'. -Porting to a new version of coff --------------------------------- - -The recommended method is to select from the existing implementations -the version of coff which is most like the one you want to use. For -example, we'll say that i386 coff is the one you select, and that your -coff flavour is called foo. Copy `i386coff.c' to `foocoff.c', copy -`../include/coff/i386.h' to `../include/coff/foo.h', and add the lines -to `targets.c' and `Makefile.in' so that your new back end is used. -Alter the shapes of the structures in `../include/coff/foo.h' so that -they match what you need. You will probably also have to add `#ifdef's -to the code in `coff/internal.h' and `coffcode.h' if your version of -coff is too wild. - - You can verify that your new BFD backend works quite simply by -building `objdump' from the `binutils' directory, and making sure that -its version of what's going on and your host system's idea (assuming it -has the pretty standard coff dump utility, usually called `att-dump' or -just `dump') are the same. Then clean up your code, and send what -you've done to Cygnus. Then your stuff will be in the next release, and -you won't have to keep integrating it. -How the coff backend works --------------------------- - -File layout -........... - -The Coff backend is split into generic routines that are applicable to -any Coff target and routines that are specific to a particular target. -The target-specific routines are further split into ones which are -basically the same for all Coff targets except that they use the -external symbol format or use different values for certain constants. - - The generic routines are in `coffgen.c'. These routines work for -any Coff target. They use some hooks into the target specific code; -the hooks are in a `bfd_coff_backend_data' structure, one of which -exists for each target. - - The essentially similar target-specific routines are in -`coffcode.h'. This header file includes executable C code. The -various Coff targets first include the appropriate Coff header file, -make any special defines that are needed, and then include `coffcode.h'. - - Some of the Coff targets then also have additional routines in the -target source file itself. - - For example, `coff-i960.c' includes `coff/internal.h' and -`coff/i960.h'. It then defines a few constants, such as `I960', and -includes `coffcode.h'. Since the i960 has complex relocation types, -`coff-i960.c' also includes some code to manipulate the i960 relocs. -This code is not in `coffcode.h' because it would not be used by any -other target. -Bit twiddling -............. - -Each flavour of coff supported in BFD has its own header file -describing the external layout of the structures. There is also an -internal description of the coff layout, in `coff/internal.h'. A major -function of the coff backend is swapping the bytes and twiddling the -bits to translate the external form of the structures into the normal -internal form. This is all performed in the `bfd_swap'_thing_direction -routines. Some elements are different sizes between different versions -of coff; it is the duty of the coff version specific include file to -override the definitions of various packing routines in `coffcode.h'. -E.g., the size of line number entry in coff is sometimes 16 bits, and -sometimes 32 bits. `#define'ing `PUT_LNSZ_LNNO' and `GET_LNSZ_LNNO' -will select the correct one. No doubt, some day someone will find a -version of coff which has a varying field size not catered to at the -moment. To port BFD, that person will have to add more `#defines'. -Three of the bit twiddling routines are exported to `gdb'; -`coff_swap_aux_in', `coff_swap_sym_in' and `coff_swap_linno_in'. `GDB' -reads the symbol table on its own, but uses BFD to fix things up. More -of the bit twiddlers are exported for `gas'; `coff_swap_aux_out', -`coff_swap_sym_out', `coff_swap_lineno_out', `coff_swap_reloc_out', -`coff_swap_filehdr_out', `coff_swap_aouthdr_out', -`coff_swap_scnhdr_out'. `Gas' currently keeps track of all the symbol -table and reloc drudgery itself, thereby saving the internal BFD -overhead, but uses BFD to swap things on the way out, making cross -ports much safer. Doing so also allows BFD (and thus the linker) to -use the same header files as `gas', which makes one avenue to disaster -disappear. -Symbol reading -.............. - -The simple canonical form for symbols used by BFD is not rich enough to -keep all the information available in a coff symbol table. The back end -gets around this problem by keeping the original symbol table around, -"behind the scenes". - - When a symbol table is requested (through a call to -`bfd_canonicalize_symtab'), a request gets through to -`coff_get_normalized_symtab'. This reads the symbol table from the coff -file and swaps all the structures inside into the internal form. It -also fixes up all the pointers in the table (represented in the file by -offsets from the first symbol in the table) into physical pointers to -elements in the new internal table. This involves some work since the -meanings of fields change depending upon context: a field that is a -pointer to another structure in the symbol table at one moment may be -the size in bytes of a structure at the next. Another pass is made -over the table. All symbols which mark file names (`C_FILE' symbols) -are modified so that the internal string points to the value in the -auxent (the real filename) rather than the normal text associated with -the symbol (`".file"'). - - At this time the symbol names are moved around. Coff stores all -symbols less than nine characters long physically within the symbol -table; longer strings are kept at the end of the file in the string -table. This pass moves all strings into memory and replaces them with -pointers to the strings. - - The symbol table is massaged once again, this time to create the -canonical table used by the BFD application. Each symbol is inspected -in turn, and a decision made (using the `sclass' field) about the -various flags to set in the `asymbol'. *Note Symbols::. The generated -canonical table shares strings with the hidden internal symbol table. - - Any linenumbers are read from the coff file too, and attached to the -symbols which own the functions the linenumbers belong to. -Symbol writing -.............. - -Writing a symbol to a coff file which didn't come from a coff file will -lose any debugging information. The `asymbol' structure remembers the -BFD from which the symbol was taken, and on output the back end makes -sure that the same destination target as source target is present. - - When the symbols have come from a coff file then all the debugging -information is preserved. - - Symbol tables are provided for writing to the back end in a vector -of pointers to pointers. This allows applications like the linker to -accumulate and output large symbol tables without having to do too much -byte copying. - - This function runs through the provided symbol table and patches -each symbol marked as a file place holder (`C_FILE') to point to the -next file place holder in the list. It also marks each `offset' field -in the list with the offset from the first symbol of the current symbol. - - Another function of this procedure is to turn the canonical value -form of BFD into the form used by coff. Internally, BFD expects symbol -values to be offsets from a section base; so a symbol physically at -0x120, but in a section starting at 0x100, would have the value 0x20. -Coff expects symbols to contain their final value, so symbols have -their values changed at this point to reflect their sum with their -owning section. This transformation uses the `output_section' field of -the `asymbol''s `asection' *Note Sections::. - - * `coff_mangle_symbols' This routine runs though the provided symbol -table and uses the offsets generated by the previous pass and the -pointers generated when the symbol table was read in to create the -structured hierachy required by coff. It changes each pointer to a -symbol into the index into the symbol table of the asymbol. - - * `coff_write_symbols' This routine runs through the symbol table -and patches up the symbols from their internal form into the coff way, -calls the bit twiddlers, and writes out the table to the file. -`coff_symbol_type' -.................. - -*Description* -The hidden information for an `asymbol' is described in a -`combined_entry_type': -. - typedef struct coff_ptr_struct - { - - /* Remembers the offset from the first symbol in the file for - this symbol.

The symbol index to -use is removed from the `offset' field in the symbol table supplied. -The address comes directly from the sum of the section base address and -the relocation offset; the type is dug directly from the howto field. -Then the `internal_reloc' is swapped into the shape of an -`external_reloc' and written out to disk. -Reading linenumbers -................... - -Creating the linenumber table is done by reading in the entire coff -linenumber table, and creating another table for internal use. - - A coff linenumber table is structured so that each function is -marked as having a line number of 0. Each line within the function is -an offset from the first line in the function. The base of the line -number information for the table is stored in the symbol associated -with the function. - - The information is copied from the external to the internal table, -and each symbol which marks a function is marked by pointing its... - - How does this work ? -Reading relocations -................... - -Coff relocations are easily transformed into the internal BFD form -(`arelent'). - - Reading a coff relocation table is done in the following stages: - - * Read the entire coff relocation table into memory. - - * Process each relocation in turn; first swap it from the external - to the internal form. - - * Turn the symbol referenced in the relocation's symbol index into a - pointer into the canonical symbol table. This table is the same - as the one returned by a call to `bfd_canonicalize_symtab'. The - back end will call that routine and save the result if a - canonicalization hasn't been done. - - * The reloc index is turned into a pointer to a howto structure, in - a back end specific way. For instance, the 386 and 960 use the - `r_type' to directly produce an index into a howto table vector; - the 88k subtracts a number from the `r_type' field and creates an - addend field. - -File: bfd.info, Node: elf, Prev: coff, Up: BFD back ends - -ELF backends -============ - -BFD support for ELF formats is being worked on. Currently, the best -supported back ends are for sparc and i386 (running svr4 or Solaris 2). - - Documentation of the internals of the support code still needs to be -written. The code is changing quickly enough that we haven't bothered -yet. -`bfd_elf_find_section' -...................... - -*Synopsis* - struct elf_internal_shdr *bfd_elf_find_section (bfd *abfd, char *name); - *Description* -Helper functions for GDB to locate the string tables. Since BFD hides -string tables from callers, GDB needs to use an internal hook to find -them. Sun's .stabstr, in particular, isn't even pointed to by the -.stab section, so ordinary mechanisms wouldn't work to find it, even if -we had some. - -File: bfd.info, Node: Index, Prev: BFD back ends,
