Ian Lance Taylor	f8ee1ebba0	Added some support for Irix 4 shared libraries. * ecoff.c (ecoff_new_section_hook): Set SEC_SHARED_LIBRARY for a .lib section. (ecoff_sec_to_styp_flags): Set SEC_SHARED_LIBRARY if STYP_ECOFF_LIB bit is set. (ecoff_compute_section_file_positions): Round the contents of a .lib section up to the next page boundary. (ecoff_set_section_contents): If we see a .lib section, increment the vma by one to count the number of shared libraries we have. (ecoff_write_object_contents): Don't crash if we see a STYP_ECOFF_LIB section, and don't adjust text_start or data_start or bss_size either.	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.

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

David MacKenzie	9783e04a64	Make all callers of malloc or realloc (including via obstacks) check the result for NULL.
