Subject: [ARC] Fix case-sensitivity for extension instructions.
X-Git-Tag: users/ARM/embedded-binutils-master-2018q4~1296
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f02806be1ff3d25fdf4d9e06ced33c4b138458aa;p=external%2Fbinutils.git

[ARC] Fix case-sensitivity for extension instructions.

In ARC assembler, we accept case insensitive mnemonics, but this was
not the case for extension instruction, fix it and add a test.

	* config/tc-arc.c (tokenize_extinsn): Convert to lower case the
	name of extension instructions.
	* testsuite/gas/arc/textinsn_case.d: New file.
	* testsuite/gas/arc/textinsn_case.s: Likewise.
