Subject: opcodes: blackfin: catch invalid loopsetup insns
X-Git-Tag: cygwin-1_7_8-release~147
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=298c1ec2a052b71bd60c244f2c3f8c6367214af1;p=thirdparty%2Fbinutils-gdb.git

opcodes: blackfin: catch invalid loopsetup insns

The LoopSetup insn is only valid when the reg field is 0-7, so
don't go decoding it incorrectly when reg is 8-15.
