Ian Lance Taylor	d1b44e837e	* elf.c (bfd_elf_generic_reloc): If this is not an inplace reloc, then skip bfd_perform_relocation even if the addend is non-zero.	33 years ago
Ken Raeburn	32090b8e4f	* elf.c, elfcode.h, libelf.h: Serious reorganization. Deleted `thunk' structure, merged into tdata, duplicate data eliminated. Rearranged functions, grouping by function. Broke up many functions in elfcode.h, re-ordered many parts of file writing to handle unpredictable state of section relocation table as provided by various applications. Still needs cleanup: Merge functions back together, split out data structure with only data that is used only when writing out object file. * elf.c (bfd_elf_generic_reloc): New function, taken from coff-mips.c. * elf32-sparc.c (elf_sparc_howto_table): Use it, to work around bfd_perform_relocation lossage.	34 years ago

John Gilmore	5f9ca96038	* aout-adobe.c, aoutf1.h, aoutx.h, bout.c coff-m68k.c, coff-z8k.c, coffcode.h, elf.c, libaout.h, libbfd.h, srec.c: Lint.	34 years ago
John Gilmore	f8e0194018	* aout-adobe.c, aoutf1.h, archive.c, bout.c, coff-rs6000.c, coffcode.h, elf.c, ieee.c, libaout.h, libbfd.c, oasys.c, sco-core.c: Lint: Second argument of bfd_seek is always file_ptr. Third argument is SEEK_SET or SEEK_CUR. Result is always 0 or -1.	34 years ago
Steve Chamberlain	294eaca479	Some of these are guesses, if you know different, just yell. Thu Oct 8 08:52:48 1992 Steve Chamberlain (sac@thepub.cygnus.com) Now a bfd knows whether underscores are normally prepended to symbols in its file format. Helps with error messages. * aout-adobe.c, aout-target.h, bout.c, coff-a29k.c, coff-h8300.c, coff-z8k.c: targets set so they have leading underscore * coff-i386.c, coff-i960.c, coff-m68k.c, coff-mips.c, coff-m88k.c, coff-rs6000.c, coff-we32k.c, elf.c, ieee.c, srec.c: targets set without leading underscore flag * targets.c: add symbol leading char to xvec description * bfd-in.h (bfd_get_symbol_leading_char): new macro.	34 years ago
Brendan Kehoe	13ff13438b	* elf.c (section_from_elf_index): Return bfd_abs_section, not 0, since we should never have a NULL section. (elf_slurp_symbol_table): If st_shndx doesn't match any of our tests, set the section to bfd_abs_section.	34 years ago
Fred Fish	3dfa6cfb66	* config/stratus.mt (CC): Remove definition. * elf.c (bfd_section_from_shdr, elf_section_from_bfd_section, section_from_elf_index): Add SHT_BEPROGBITS case for i860 in big endian mode. * elf.c (bfd_section_from_shdr): Test for the possibility that section_from_elf_index returns NULL and don't dereference it.	35 years ago
Fred Fish	97225e37f7	* elf.c: Remove "(void)" casts from function calls where the return value is ignored, in accordance with GNU coding standards.	35 years ago
Fred Fish	ec6b2951da	* libbfd.h, libbfd-in.h (bfd_seek): Make prototype match definition. * reloc.c (bfd_default_reloc_type_lookup): Make cast on return type match actual return type. * elf_print_symbol (section_name): Make CONST.	35 years ago
John Gilmore	796aae470c	* elf.c (bfd_elf_find_section): Mark as INTERNAL_FUNCTION so its prototype will be included in libbfd.h. Change result type to struct * (rather than equivalent typedef) so it can be used in the prototype, where they typedef won't be known. * libbfd.h: Updated version.	35 years ago
Fred Fish	91f781ffbb	* elf.c (bfd_section_from_shdr, elf_slurp_symbol_table): Correct misconception that there can be only one symbol table. Only call elf_slurp_symbol_table on the full symbol table, not the dynamic one which is only a subset of the full one. (The bfd library was slurping in the first ELF symbol table it found and then ignoring any others. For dynamically linked executables, this happened to be the dynamic symbol table, which is a subset of the full symbol table and only contains the symbols that need to be used in dynamic linking.)	35 years ago
John Gilmore	80bdcb77bd	* elf.c (elf_obj_tdata): Merge elf_obj_tdata_struct and elf_core_tdata_struct into a single common struct. Core files wouldn't have worked at all without this. (bfd_elf_find_section): New function for GDB's undercover use to find string sections that BFD hides from it. (elf_get_str_section): Avoid multiple alloc&reads for same data; lint. (elf_object_p, elf_core_file_p): Allocate internal file header storage dynamically. * bfd.c (union {...} tdata): Remove elf_core_tdata_struct. * demo64.c: Prevent "empty translation unit" warnings from idiots.	35 years ago
Fred Fish	808dfd5aab	Fix couple of function args that expect to be passed CONST pointers, and boolean functions that were returning NULL, which can be "void *" rather than just bare 0.	35 years ago
Mark Eichin	37ac3b76ec	Massive changes. Elf sections are now processed into BFD sections only if they make sense as independent sections; symbols and relocs are turned into BFD symbols and relocs; objects are now created. objdump and copy mostly work on .o files. this check-in will be followed by gdb testing. the code has not yet been split up the way coff is to support multiple architectures and bit widths. no ChangeLog entries yet; too big... nearly everything changed.	35 years ago
Fred Fish	d4acec2c22	Fix to use a single disposable copy of section header table and program header table entries.	35 years ago
Fred Fish	d01cd8fc75	Makefile.in: Add dependencies for various coff-*.o files. elf.c: Remove extraneous paren from core_prpsinfo and core_prpstatus macros, rename core_prpstatus to core_prstatus. Replace references to old section "size" member with new "_raw_size" member. Implement elf_make_empty_symbol, which is now used.	35 years ago
Steve Chamberlain	e98e6ec111	Uses the new small reloc type now. Currently self hosts on sun4 and sun3	35 years ago
Fred Fish	e83f304031	Enclose corename and execname inside a HAVE_PROCFS ifdef, since they are unused when it is not defined.	35 years ago
Steve Chamberlain	c3eb25fc25	* aout-encap.c, aoutf1.h, aoutx.h, archive.c, bout.c, coff-a29k.c, coff-h8300.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c, coff-mips.c, coff-rs6000.c, cpu-h300.c, elf.c, i386aout.c, newos3.c, stab-syms.c, syms.c: All these files have had their #includes altered to point to the new places.	35 years ago
Fred Fish	eb8983c9ca	Fix bug in elf.c (missing "break" statements in cases), add ncr and SVR4 i386 support to configuration.	35 years ago
John Gilmore	8c4a1ace3d	ALIGN->BFD_ALIGN	35 years ago
Fred Fish	a6c1d73165	Don't try to create a bfd section for the first ELF section header table entry, since it is just a placeholder with no name.	35 years ago
Fred Fish	e0796d2213	Add partial support for ELF format corefiles. Still needs code to extract register values from corefiles and make them available to bfd clients.	35 years ago
Steve Chamberlain	9ce0058ca6	* empty log message *	35 years ago
