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 support for new style asymbols and + bfd_print_symbol. Fixed so that asymbol and + reloc records are handled correctly.

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 <stdlib.h> 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.
