Hans Wennborg 504991638f Revert r312154 "Re-enable "[MachineCopyPropagation] Extend pass to do COPY source forwarding"" ... It caused PR34387: Assertion failed: (RegNo < NumRegs && "Attempting to access record for invalid register number!") > Issues identified by buildbots addressed since original review: > - Fixed ARMLoadStoreOptimizer bug exposed by this change in r311907. > - The pass no longer forwards COPYs to physical register uses, since > doing so can break code that implicitly relies on the physical > register number of the use. > - The pass no longer forwards COPYs to undef uses, since doing so > can break the machine verifier by creating LiveRanges that don't > end on a use (since the undef operand is not considered a use). > > [MachineCopyPropagation] Extend pass to do COPY source forwarding > > This change extends MachineCopyPropagation to do COPY source forwarding. > > This change also extends the MachineCopyPropagation pass to be able to > be run during register allocation, after physical registers have been > assigned, but before the virtual registers have been re-written, which > allows it to remove virtual register COPY LiveIntervals that become dead > through the forwarding of all of their uses. llvm-svn: 312178		2017-08-30 22:11:37 +00:00
