Sean Eric Fagan	e770a59413	Missing BFD_RELOC_26.	33 years ago
Ian Lance Taylor	326e32d7ce	Wed Mar 30 16:25:41 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com) Changes to let BFD return an error indication from get_symtab_upper_bound, bfd_canonicalize_symtab, bfd_get_reloc_upper_bound, and bfd_canonicalize_reloc. They now return long instead of unsigned int, and use -1 to indicate an error. Along the way, rename get_symtab_upper_bound to bfd_get_symtab_upper_bound. * bfd.c (bfd_get_reloc_upper_bound): Return long, and -1 on errors. (bfd_canonicalize_reloc): Likewise. * syms.c (bfd_get_symtab_upper_bound): Renamed from get_symtab_upper_bound. * targets.c (bfd_target): Renamed _get_symtab_upper_bound to _bfd_get_symtab_upper_bound, and changed it and _bfd_canonicalize_symtab and _get_reloc_upper_bound and _bfd_canonicalize_reloc to all return long. * aoutx.h (NAME(aout,get_symtab)): Return long, and -1 on errors.

Jim Kingdon	80425e6c82	* libbfd-in.h: Remove alloca cruft. It was missing some necessary 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: Replace alloca with malloc and appropriate error checking and freeing. * linker.c: Replace alloca with obstack_alloc. * libbfd.h: Rebuilt.	33 years ago
