5c8444f8f8 Add bfd_free_cached_info support to a.out backends.
* aoutx.h (aout_get_external_symbols): Renamed from

	read the symbols.  Allocate the cached symbols with malloc, not

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.

250578363e * libbfd.c (bfd_read): Set bfd_error as appropriate for a short
read. (bfd_error_system_call or bfd_error_file_truncated).

        * som.c: Do not blindly set bfd_error_system_call after a
        failing bfd_read, bfd_write, or bfd_seek.  In a few places
        (like som_object_p) override the error status set by bfd_read.

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.

ca16370388 (b_out_get_reloc_upper_bound): For BSS section, just return 0.
(aligncode): When shrinking, the addend should be set to the current offset in
the section plus the number of bytes of padding that will actually be retained.
(b_out_relax_section): If a section contains no relocations, don't bother
processing them.
(b_out_get_relocated_section_contents): Set reloc_done.  Assert that
bfd_get_section_contents returns true.  Check that relocs are properly ordered.
(b_out_get_relocated_section_contents, case ALIGNDONE): Assert that reloc's
addend falls between the current source offset and the raw size of the input
section.

Changed some indentation, deleted trailing whitespace, fixed some comments,
removed some "#if 1" lines.
(output_addr): New macro.
(calljx_callback, callj_callback, get_value, abs32code, aligncode,
b_out_get_relocated_section_contents): Use it for readability.

	(get_value): If the symbol is undefined, look it up in the linker
	hash table.
	(b_out_get_relocated_section_contents): For PCREL24 and PCREL13
	use get_value to get the symbol value and check for undefined
	symbols.
	* reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
	undefined, look it up in the linker hash table.

	* coffgen.c, libcoff-in.h (coff_bfd_make_debug_symbol): Renamed
	from coff_make_debug_symbol.
	* libcoff.h: Updated accordingly.

* section.c (SEC_IS_COMMON): New section flag, needed for MIPS
	ECOFF which has two common sections.
	(bfd_com_section): Set SEC_IS_COMMON flag.
	* bfd-in.h (bfd_is_com_section): New macro to test SEC_IS_COMMON.

Thu Oct  8 08:52:48 1992  Steve Chamberlain  (sac@thepub.cygnus.com)

	 Now a bfd knows whether underscores are normally prepended
