Subject: 	* elf32-spu.c (struct spu_link_hash_table): Add "stubs".
X-Git-Tag: sid-snapshot-20071001~72
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=98e89a7d8460331aaf46665d74bbc6491cfac14d;p=platform%2Fupstream%2Fbinutils.git

	* elf32-spu.c (struct spu_link_hash_table): Add "stubs".
	(spu_elf_link_hash_table_create): Init new field.
	(spu_elf_size_stubs): Store sorted stub syms in new htab field
	rather than local var.
	(spu_elf_build_stubs): Iterate over htab stubs rather than
	hash traversal.
	(struct stubarr): Delete.
	(allocate_spuear_stubs, populate_stubs, write_one_stub): Adjust.
