	* som.c (som_canonicalize_reloc): Likewise.
	* hp300hpux.c (MY(slurp_reloc_table)): Likewise.  Also, if malloc
	returns NULL, don't report an error if we asked for zero bytes.
	* i386lynx.c (NAME(lynx,slurp_reloc_table)): If malloc returns
	NULL, don't report an error if we asked for zero bytes.

Jeff Law 1f46bba327 * som.c (som_slurp_string_table): Use malloc to allocate space
for the cached copy of the native string table.
        (som_slurp_symbol_table): Likewise for the native symbol table.
        (som_slurp_reloc_table): Likewise for the native and generic
        relocation tables.
        (som_bfd_free_cached_info): Free the cached native strings,
        symbols, and relocations.  Also free the canonical cached relocations.

Ian Lance Taylor 9deaaaf1b3 * targets.c (bfd_target): Add _bfd_free_cached_info field.
* bfd.c (bfd_free_cached_info): Define.
	* bfd-in.h (JUMP_TABLE): Add _bfd_free_cached_info.
	* bfd-in2.h: Rebuilt.
	* All backends: Initialize bfd_free_cached_info entry point to
	bfd_true.

Jeff Law 06e6eb0e53 * som.c (som_begin_writing): New approach at dealing with holes
in executables left by the HP linker.  Does not rely on subspace
        alignments as subspaces are *NOT* guaranteed to be properly
        aligned in an executable (can you believe that!).
