Subject: AMDGPU: Fix not adding exec to defs of cmpx instruction pseudos
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=88ba582891a62e78083da17610a746b4dfa13b30;p=oota-llvm.git

AMDGPU: Fix not adding exec to defs of cmpx instruction pseudos

This was only set on the final _si/_vi version, but not
on the pseudos most of codegen sees.

No test since these instructions aren't used yet.
