is trivially rematerializable and integrate it into TargetInstrInfo::isTriviallyReMaterializable. This way, all places that need to know whether an instruction is rematerializable will get the same answer. This enables the useful parts of the aggressive-remat option by default -- using AliasAnalysis to determine whether a memory location is invariant, and removes the questionable parts -- rematting operations with virtual register inputs that may not be live everywhere. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83687 91177308-0d34-0410-b5e6-96231b3b80d8 |
