(NAME(aout,link_hash_table_init)): New function. (NAME(aout,link_hash_table_create)): Call NAME(aout,link_hash_table_init), not _bfd_link_hash_table_init.

1994-03-10 * libbfd-in.h: Remove alloca cruft. It was missing some necessaryJim Kingdon1-4/+7
cruft (like the #pragma alloca for AIX). In addition to that problem, the C alloca calls xmalloc, which means checking for being out of memory can't work right. The following changes remove all uses of alloca from BFD. * hosts/solaris2.h: Remove alloca cruft. * som.c: Replace alloca with a fixed size auto array. * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c, ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c, sunos.c: Replace alloca with malloc and appropriate error checking and freeing. * linker.c: Replace alloca with obstack_alloc. * libbfd.h: Rebuilt.

choose_reloc_size. (sunos4_write_object_contents) now calls choose_reloc_size so outputs relocs correctly, also calculates the size of the sections correctly. * aout.c: (look in the rrgs I hate VI) ~ ~ ~ ~

1991-05-11 * sunos.c: Remove all code that goes in aout.c. Split outJohn Gilmore1-1404/+77
machine dependent followup in sunos4_object_p into sunos4_callback. Use JUMP_TABLE(aout) 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.

* sunos.c (sunos4_set_section_contents): Made it so that sections are always padded to their alignment size.
1991-05-08Various portability lints.Steve Chamberlain1-1/+3
Fixed reloc bug in ieee and oasys.
1991-05-04Saber C cleanup. Fix horrid bug in opncls.c in which an obstack isJohn Gilmore1-5/+5
initialized on the stack and then copied into its own allocated space. (Wow, Steve, you're twisted...)

1991-05-02Merge Per Bothner's MIPS changes from 31 March 1991 (bfd-0.5.2-patch1a)John Gilmore1-1/+0
and make the result compile and run on the DEC 3100. It still has trouble running but it can handle opening exec and symbol files in ecoff format.
1991-05-02Merge devo/bfd with GDB's bfd.John Gilmore1-272/+206
Remove obstack.h to ../include and obstack.c to ../libiberty. Move COFF symbol swapping code to coffswap.c where GDB can call it but it won't be duplicated if we have N different COFF targets. Add support for traditional Unix core files (with a upage). This support is from an Ultrix port, but is probably slightly broken now. Improve bfd_release's of obstack'd items on error returns. gcc -Wall fixes. Handle section alignment slightly better in coff, and comment where it needs more work (on page-aligning virtual vs file addresses for DPAGED). Use set_tdata everywhere that tdata is set, to avoid "cast to the left of assignment" problems with some compilers. Move bfd_alloc, bfd_zalloc, bfd_realloc, and bfd_release into libbfd.h (from bfd.h) since they are internal routines. Remove the redundant suffix "_struct" from struct tags. Set symbol count early in file reading, before slurping in the syms, for GDB's use.
1991-04-25Minor changes to accomodate merging of three include file directories.John Gilmore1-6/+7
1991-04-24Changed the shape of the howto type yet again.Steve Chamberlain1-36/+35
