Detailed Description

Defines a builder that does CSE of MachineInstructions using GISelCSEInfo.

Eg usage.

GISelCSEInfo *Info = &getAnalysis<GISelCSEAnalysisWrapperPass>().getCSEInfo(); CSEMIRBuilder CB(Builder.getState()); CB.setCSEInfo(Info); auto A = CB.buildConstant(s32, 42); auto B = CB.buildConstant(s32, 42); assert(A == B); unsigned CReg = MRI.createGenericVirtualRegister(s32); auto C = CB.buildConstant(CReg, 42); assert(C->getOpcode() == TargetOpcode::COPY); Explicitly passing in a register would materialize a copy if possible. CSEMIRBuilder also does trivial constant folding for binary ops.
