Jakob Stoklund Olesen 1c062c24ab Fix -widen-vmovs liveness issues. ... When widening a copy, we are reading a larger register that may not be live. Use an <undef> flag to tell the register scavenger and machine code verifier that we know the value isn't defined. We now widen: %S6<def> = COPY %S4<kill>, %D3<imp-def> into: %D3<def> = VMOVD %D2<undef>, pred:14, pred:%noreg, %S4<imp-use,kill> This also keeps the <kill> flag on %S4 so we don't inadvertently kill a live value in %S5. Finally, ensure that ARMBaseInstrInfo::setExecutionDomain() preserves the <undef> flag when converting VMOVD to VORR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141746 91177308-0d34-0410-b5e6-96231b3b80d8		2011-10-12 00:06:23 +00:00
