From: Mike Frysinger Date: Wed, 22 Sep 2010 20:37:25 +0000 (+0000) Subject: opcodes: blackfin: fix decoding of LSHIFT insns X-Git-Tag: sid-snapshot-20101001~107 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=59a82d2333aec12b174ad37f2f385afbfe06cf45;p=external%2Fbinutils.git opcodes: blackfin: fix decoding of LSHIFT insns The Blackfin ISA does not have a "SHIFT" insn, it has either LSHIFT, ASHIFT, or BXORSHIFT. So be specific when disassembling. As fall out of this change, we need to update some assembler tests.
