Subject: 	* elf32-spu.c (struct spu_link_hash_table): Remove overlay_fixed,
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2a516af65ecd776f581b5df497d29374d021f57c;p=binutils-gdb.git

	* elf32-spu.c (struct spu_link_hash_table): Remove overlay_fixed,
	reserved, and extra_stack_space members.
	(spu_elf_auto_overlay): Use auto_overlay_fixed, auto_overlay_reserved,
	and extra_stack_space members of htab->params instead.
