Subject: 	* elf32-mips.c (mips_elf_next_lo16_addend): Rename to ...
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=23b255aaddaf15fd568d27128f5c00d62a6486a6;p=binutils-gdb.git

	* elf32-mips.c (mips_elf_next_lo16_addend): Rename to ...
	(mips_elf_next_lo16_relocation): Don't compute the addend here.
	Just return the relocation found.
	(mips_elf_relocate_section): Pull the LO16 addend out of the
	section itself when using REL relocations.
