Subject: X86InstrInfoSSE.td declares PINSRW as having type v8i16,
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=8f2b4cc07161b56e56d6615761ea4ba08dc0e7d3;p=oota-llvm.git

X86InstrInfoSSE.td declares PINSRW as having type v8i16,
don't alis it in the MMX .td file with a different width,
split into two X86ISD opcodes.  This fixes an x86 testcase.
