Mon Aug 19 13:48:22 1991 Roland H. Pesch (pesch at cygint.cygnus.com) * aoutx.h, archive.c, archures.c, bfd.c, bfd.texinfo, cache.c, coffcode.h, core.c, format.c, libbfd.c, libbfd.h, libcoff.h, opncls.c, reloc.c, section.c, syms.c, targets.c (documentation segments): used BFD (caps) more consistently as a name in discourse, fixed a few other minor typos and uses of fonts Thu Aug 8 16:47:43 1991 Steve Chamberlain (steve at cygint.cygnus.com) * coffcode.h: fixed bug where string table size wasn't being swapped. Thu Aug 1 16:35:28 1991 Steve Chamberlain (steve at cygint.cygnus.com) * section.c: added SEC_CONSTRUCTOR_TEXT|DATA|BSS flags * syms.c: added BSF_CONSTRUCTOR, BSF_WARNING and BSF_INDIRECT flags. (bfd_print_symbol_vandf) now knows what to do with the above flags. * aoutx.h: made translate_from_native_sym_flags and translate_to_native_sym_flags produce the above flags. Wed Jul 31 09:53:52 1991 John Gilmore (gnu at cygint.cygnus.com) * all files: update copyright notices for GPL version 2. Install header comments and attribute most modules to their authors. BFD's name is now officially "Binary File Descriptor", so remove any conflicting pejoratives. archures.h: Consists solely of comments; remove it. Fri Jul 26 18:11:34 1991 Steve Chamberlain (steve at cygint.cygnus.com) * Makefile.in, bfd.c: Made it compile again. Fri Jul 19 08:17:09 1991 Steve Chamberlain (steve at cygint.cygnus.com) * newsos3.c, targets.c, coffcode.h: new patches from David Wood Mon Jul 15 16:27:42 1991 Steve Chamberlain (steve at cygint.cygnus.com) * aoutf1.h archive.c bfd.c coffcode.h core.c ecoff.c ieee.c bfd.texinfo oasys.c opncls.c reloc.c srec.c: More documentation on lint fixes. * amdcoff.c bfd.texinfo Makefile.in : Folded in changes for amd 29k coff by David Wood (wood@lab.ultra.nyu.edu). Thu Jul 4 09:53:16 1991 Steve Chamberlain (steve at cygint.cygnus.com) * Everything: created some new files, core.c format.c, reloc.c, section.c and syms.c to split the functionality a bit better. Cleaned up the rest of the files a bit, and added some documentation. Mon Jul 1 13:29:47 1991 David Wood (wood at david.ultra.nya.edu) * opncls.c, ../include/sys/h-sun3.h ../include/sys/h-sun4.h: fcntl really takes 3 arguments, patched code and ammended prototypes. Fri Jun 14 13:19:40 1991 Steve Chamberlain (steve at cygint.cygnus.com) * ../include/bfd.h (struct bfd_target): Added new field "align_power_min" which contains the minimum alignment for a section. This is used in coff_new_section_hook. The field insertion necessitates an update of all backends.. * aoutf1.h jump table field inserted * archive.c(snarf_ar_hdr)(bfd_slurp_coff_armap) can now parse dgux style extended filenames too. * bout.c(b_out_squirt_out_relocs) fix to assertion tests. Jump table field inserted. * coffcode.h(just about everything) Now patches up symbol tables using a different mechanism. The Intel major bug has been fixed, and the linker can self host on the Aviion and be debugged with gdb. * ecoff.c: new include and jump table patch, i386coff.c: new include and jump table patch, icoff.c: new include and jump table patch, ieee.c: can now read archives containing ieee modules., libcoff.h: added (combined_entry_type), libieee.h: uped max sections to 20, m68kcoff.c: new include and jump table patch, m88kbcs.c: new include and jump table patch, oasys.c: various bugs fixed. opncls.c: added bfd_alloc_grow and bfd_alloc_finish. srec.c: jump table patch. trad-code.c fixed #IF typeo Fri Jun 7 12:35:46 1991 Sean Fagan (sef at cygint.cygnus.com) * coffcode.h (coff_swap_aux_in): added else case to deal with filenames less than 9 characters. Thu Jun 6 18:27:38 1991 Steve Chamberlain (steve at cygint.cygnus.com) * ../include/oasys.h oasys.c (oasys_archive_p): fixed so it works * srec.c: now allows any number of sections to be created in a file. Outputs addresses of the right length. Thu May 30 15:30:10 1991 Steve Chamberlain (steve at cygint.cygnus.com) * bfd.c (bfd_check_format): Fixed problem where when a defaulted target didn't match, the format got set to the attempted match, breaking a future test. *../include/i386coff.h : fixed typo in type field with size * i386coff.c icoff.c m88k-bcs.c ecoff.c ../include/bfd.h : Added support in the jump table for the swapping routines exported to gdb. Now gdb works with the 386. Tue May 28 17:21:43 1991 John Gilmore (gnu at cygint.cygnus.com) * Merge in changes from gdb-3.95 release. Makefile.in: Allow hmake and tmake files to add OFILES. aoutf1.h: bfd.c: support specific targets as well as searching. When searching, take default target in preference to others. bfd.doc: typos ieee.c, oasys.c: Avoid using the "tdata" macros left of assignment. liba.out.h: Don't hard-code file offsets; use N_ macros for them. libbfd.h: Support specific targets as well as searching. opncls.c: Support specific targets as well as searching. targets.c: Search is short-circuited if default target matches. liboasys.c, libieee.c: Undo bothner changes that make macros work to the left of assignment, but which depend on the representations of different pointer types being the same. Fri May 24 18:56:52 1991 Steve Chamberlain (steve at cygint.cygnus.com) * i386coff.c: created. * coffcode.h: added support for 386. * Makefile.in: added support for 386. * ../include/i386coff.h: created Wed May 22 07:26:38 1991 Steve Chamberlain (steve at cygint.cygnus.com) * coffcode.h: removed all put_x_ * libbfd.c: Changed #ifdef __GNUC__ to #ifdef HOST_64_BIT, Added DEFUNS Tue May 21 08:58:58 1991 Steve Chamberlain (steve at cygint.cygnus.com) (bothner) * opncls.c: Changed obstack_chunk_alloc use xmalloc Mon May 20 17:12:17 1991 Steve Chamberlain (steve at cygint.cygnus.com) * everything: Removed sysdep.h from bfd.h and put back into files from which it was split out. Now 64 bit version is built with a -DHOST_64_BIT="long long" on the compile line. Fri May 17 19:35:26 1991 Steve Chamberlain (steve at cygint.cygnus.com) Changed all the [get|put][name] routines to use [get|put]_[size in bytes]. Put in support for 64 bit work. Now two versions of bfd may be generated, according to the state of TARGET_64_BIT, one which is 32 bit only, and one which is 64/32 bits. Created new back end 'demo64' to test 64 bit functionality. Renamed some files to work on DOS. * archive.c: lint * bfd.c: prototypes and lint. * ecoff.c: added 64bit transfer * icoff.c: added 64bit transfer * ieee.c: name chage, 64 bit transfer. * liba.out.h: Split out common code from sunos and newsos into liba.out. Name changes and prototype mods. * libbfd.c: lint and prototypes, extra 64bit swaps. * libbfd.h: prototypes for new functions. * libcoff.h: lint * libieee.h: make work on DOS * liboasys.h: make work on DOS * m88k-bcs.c: Name change and 64bit stuff.* newsos3.c: common code removed, new jump table. * oasys.c: Name change * opncls.c: Portability fixes * srec.c: Name changes * sunos.c: Removed comon code. * targets.c: Added demo * aout32, aout64.c include aoutx.h * bout.c: used to be called b.out.c * coffcode.h: used to be called coff-code.h, now 64bit ized. * demo64.c: 64 bit a.out back end Thu May 16 16:02:07 1991 Steve Chamberlain (steve at cygint.cygnus.com) from bothner * libieee.h: Make ieee_data and ieee_ar_data macros usable on LHS of assignment, even when using old compilers. * liboasys.h: Ditto for oasys_data and oasys_ar_data. * m68kcoff.c: Add enum-to-int casts to accomodate old compilers. * newsos3.c: Fix definitions of SEGMENT_SIZE and TEXT_START_ADDR. * opncls.c: Define S_IXUSR, S_IXGRP, S_IXOTH if undefined. * targets.c: Add declaration of newsos3_vec. Mon May 13 10:03:29 1991 Steve Chamberlain (steve at cygint.cygnus.com) * aout.c: fixxed some of the problems with filepos calculation. (swap_ext_reloc): fixed problem with creation of relocs. (aout_set_section_contents): fixed filepos problem * coff-code.h: (swap_filehdr_in, swap_filehdr_out) add. (swap_filehdr) delete. Changed all the usage of bfd_h_put_x. (swap_aouthdr_in, swap_aouthdr_out) add. (swap_aouthdr) delete. (coff_real_object_p) cleaned up, added MIPS. (coff_object_p) cleaned up. (coff_write_object_contents) cleaned up. * ecoff.c: Totally different. Now supports ecoff fully. * icoff.c: fixed problems in relocation callout. * libcoff.h: (struct icofdata) removed hdr structure from tdata. * m68kcoff.c: updated target vector. * sunos.c: (choose_reloc_size) added: (sunos4_callback) calls choose_reloc_size. (sunos4_write_object_contents) now calls choose_reloc_size so outputs relocs correctly, also calculates the size of the sections correctly. Fri May 10 16:58:53 1991 John Gilmore (gnu at cygint.cygnus.com) Merge Per Bothner's changes to modularize BFD a.out a bit. * libbfd.h, libbfd.c (bfd_generic_get_section_contents): Add. * ieee.c: Cast enums to int before comparing them, for brain- dead compilers. * coff-code.h: Remove coff_get_section_contents, and use the generic one instead. * aout.c: Derive new module from sunos.c, containing generic support code for all kinds of a.out files. * sunos.c: Remove all code that goes in aout.c. Split out machine dependent followup in sunos4_object_p into sunos4_callback. Use JUMP_TABLE(aout) for the transver vector, and redefine only the names we CHANGE, not all the names. Drop the little-endian vector, and rename the vector as sunos4 rather than generic. * b.out.c: Use aout.c routines for most of the work. Slight changes for the new regime. Remove close_and_cleanup and get_section_contents in favor of generics. New transfer vector regime. * newsos.c: New support for Sony NEWS, another a.out format. * ecoff.c: Remove close_and_cleanup. New tvec regime. * icoff.c, m88k-bcs.c: Add write_contents to tvec. * ieee.c, oasys.c: Remove close_and_cleanup, add write_contents to tvec. * opncls.c (bfd_close): Call format-dependent write_contents routine, if writing, before calling target-dependent close_and_cleanup routine (which is now always generic, I think). * srec.c: Use bfd_alloc instead of malloc. Remove close_and_cleanup and move code from it to srec_write_object_contents. Add write_contents to tvec. * targets.c: Remove a.out little vector, replace a.out big vector with SunOS vector. FIXME: Need Vax support again now. * libbfd.h: Add write_contents format-dependent-vector to the bfd_target vector. Supply a generic close_and_cleanup routine. * liba.out.h: Handle the new aout.c split. Add prototypes for all routines defined in aout.c. Rename "sunos" things to "aout" things. Add a few fields where needed for various formats. * Makefile.in: Add aout.c and newsos.c. * archive.c, ieee.c, oasys.c: Lint. Fri May 10 12:34:48 1991 Steve Chamberlain (steve at cygint.cygnus.com) * ../include/bfd.h changed forward declaration struct stat; to reduce warnings. Changed comment on bfd_h__x. * ../include/m68kcoff.h, ../include/intel-coff.h, ../include/m88k-bcs.h Now there are two incarnations of relocs, linenos and syments. 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. Fixed the same reloc bug that was in b.out.c * sysdep.h: Now compiles on a Posix box Wed Jan 30 21:36:26 1991 John Gilmore (gnu at cygint.cygnus.com) * icoff.c: Fix comment on big-endian version. * coff-code.h: Make HAS_RELOC really work (it's backwards from F_RELFLG). Set F_AR32WR in output files if little endian architecture. Tue Jan 29 20:56:10 PST 1991 steve@cygnus.com * archures.c fixed =/== typo * sunos.c added architecture stuff for output. Fixed bug where files where vma(data) != size(text) were processed wrong. * coff-code.h added a lint cast * (../include/a.out.sun4.h) fixed it so zmagic worked Mon Jan 28 19:15:29 PST 1991 steve@cygnus.com * archive.c removed loads of includes, and fixed bug where string table didn't have a null at the end. * bfd.c fixed includes, added symbols argument to canonicalize_reloc entry point. * libbfd.c fixed includes and added some lint patches. * targets.c added both sorts of intel coff. * b.out.c fixed included, changed was the canonical relocs were done. * icoff.c added support for callj and big and little enidian tables. * opncls.c added chmod+xing for files with EXEC_P set. * sunos.c fixed includes. Changed default section alignement to words. Fixed relocation stuff to work with new scheme * bfd.h various new types added, prototype for new reloc calls, changed bfd->iostream to a void * to including files don't need stdio.h. * libcoff.h added conversion table to tie relocs to canonical symbols * sysdep.h created * coff-code.h fixed includes. Added code to support big and little endian formats. Various lints. Better processing of symbols. Changed reloc stuff to new order * libbfd.h fixed includes Mon Jan 21 11:53:51 PST 1991 steve@cygnus.com * bfd.h changed name of alignment entry in sec_struct to alignment_power, because of conflicting uses within bfd. Now it should be obvious that it's a 2**n alignment specifier. Removed start_pad, end_alignment, block, minsize, output_file_alignment, subsection_alignment and original_vma fields. Added align_power() macro. Fixed bfd_section_alignment acessor macros. Added bfd_symbol_same_target macro. * b.out.c (b_out_write_object_contents) fixed to use new alignment member. Fixed (callj_callback) to use section relative symbols properly. * sunos.c (sunos4_object_p) fixed to use new alignment_power. Fixed (translate_from_native_sym_flags) to correctly make symbols section relative. * bfd.c (bfd_errmsg) fixed various enum cast problems. (bfd_make_section) took out initialization of obsolete members. (bfd_print_symbol_vandf) added * opncls.c (bfd_create) created. * coff-code.h (coff_new_section_hook) took away refs to obsolete members. (make_a_section_from_file) added conversion between alignment types. (coff_symbol_from) added. (coff_count_linenumbers) only counts linenumbers if symbol is of coff-type. (coff_mangle_symbols) only heavily mangles symbols if symbol is coff-type. (coff_write_symbols) various lints. (coff_write_object_contents) various lints and modification for alignment conversion. (coff_slurp_relocs) fixed for use with new asection shape. Sat Jan 19 16:10:42 PST 1991 steve@cygnus.com * archive.c lots of lint * b.out.c added callj relocation support, upgrated reloc howto. Fixed so that asymbol and reloc records are output correctly. * bfd.c lots of lint, support for new bfd entry point bfd_print_symbol. * bfd.h changed definition of asymbol to contain pointer to owning bfd, removed target dependencies. * cache.c took out print statements, put in BFD_ASSERT calls. * coff-code.h various lints, corrected linenumber output functionality.

Added timestamp. * icoff.c Added support for new howto shape. * liba.out.h Added support for new asymbol shape * libbfd.c various lints * libbfd.h various lints * libcoff.h added support for new asymbol shape. * sunos.c various lints. Added support for new asymbol shape and bfd_print_symbol. Wed Jan 16 21:38:09 PST 1991 steve@cygnus.com * b.out.c removed prototype of sunos4_ennativate_symtab, lots of pointer lint. Added support for callj relocation. Fixed bug where the last 32 bytes of the text section were overwritten by data. Fixed bug where archives of b.out didn't work due bfd_slurp_extended_name_table returning false. * sunos.c added support for n_other field. Braced the howto table so that it won't be affected by any lengthing of the howto struct typedef. Various lints * bfd.h added support for n_other field, added special_function reloc type, modified bfd_perform_relocation prototype. Added bfd_h_get_x macros. * bfd.c upgraded bfd_perform_relocation, various lints. Wed Jan 16 01:55:53 1991 John Gilmore (gnu at rtl) * ChangeLog: Started ChangeLog for BFD. * ToDo: Create file for suggestions. * Makefile: Support easy loading into Saber C. Add dependencies for icoff.o and bcs88kcoff.o. Rename coff.c to coff-code.h. Change callers. * bfd.c (bfd_check_format): Allow the check_format routines to return the desired target vector, rather than just a Boolean. bfd.h (bfd_check_format): Change function pointer return type. archive.c (bfd_generic_archive_p): change callee. b.out.c (b_out_little_object_p, b_out_big_object_p, b_out_real_object_p): change callee. libbfd.c (_bfd_dummy_target): Dummy routine replacing bfd_false in check_format transfer vectors that need a filler. libbfd.h (bfd_generic_archive_p, _bfd_dummy_target): Fix decls. bcs88kcoff.c: change callee. coff-code.h (coff_real_object_p, coff_big_object_p): change callee. icoff.c: change callee. sunos.c (sunos4_object_p, sunos4_core_file_p): change callee. * libbfd.c (zalloc): It should actually zero the storage! This was commented out for some reason. * libbfd.h: Add malloc, xmalloc, memcpy, and fatal decls. This is so callers can avoid which doesn't exist on older systems. * bfd.c (map_over_sections): Add debugging code, since I noticed the section count for sunos core files was bad, but only GDB had detected the problem. (bfd_set_section_lineno_size, bfd_set_section_linenos, bfd_get_section_linenos): Remove obsolete functions. (bfd_apply_relocations): Use longs, not ints, for the math. * bfd.h: Declare enum boolean and struct bfd_target as well as typedefs for them. Remove obsolete bfd_get_section_lineno_size. * cache.c: Make the "fdopen" support work. Keep better track of how many files are open. Centralize the opening of files and be sure bfd_open[rw] actually try to open the file. Evade linked list initialization problems. * b.out.c, coff-code.h, opncls.c, sunos.c: lint. * coff-code.h (coff_slurp_symbol_table): Null-terminate symtab names. * cplus-dem.c: Delete file, since it is not part of BFD. * opncls.c (bfd_openr): Eliminate misplaced #if 0 code.
