Subject: 	* config/tc-mips.c (mips_cpu): Initialize to -1.
X-Git-Tag: gdb-4_18~13193
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4bb0cc41f2fb5d838459c90926c0283c7d193857;p=external%2Fbinutils.git

	* config/tc-mips.c (mips_cpu): Initialize to -1.
	(md_begin): Don't mips_cpu if it was already set.
	(md_parse_option): For -mipsN, don't set mips_cpu if it was
	already set.  For -mcpu=, just set mips_cpu, not mips_isa.
