326e32d7ce Wed Mar 30 16:25:41 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)

	get_symtab_upper_bound, bfd_canonicalize_symtab,
	bfd_get_reloc_upper_bound, and bfd_canonicalize_reloc.  They now

ec099b4b25 * aoutx.h (NAME(aout,find_nearest_line)): The caller expects

8eb5d4be69 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
	returns NULL, it is not an error.  It's possible that some of
	these checks are not necessary (because the size can never be
	zero), but putting in the checks is the conservative thing to do
	in light of the fact that some of these malloc calls replaced
	unchecked alloca calls, in which a zero argument would work fine.
1994-03-17 18:54:48 +00:00
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.
