Subject: 	* config/tc-mips.c (cons_fix_new_mips): Only treat 8 byte reloc
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bf39474f1526af4e7b1b105a4c11d77fb1db7ad7;p=binutils-gdb.git

	* config/tc-mips.c (cons_fix_new_mips): Only treat 8 byte reloc
	specially if not ELF.
	(md_apply_fix): Handle BFD_RELOC_64.
	(tc_gen_reloc): Handle BFD_RELOC_64.
