I am looking at results from analyzePhysReg, and am getting results a little different than I expected for x86. The call to this is coming from this code in llvm::MachineBasicBlock::computeRegisterLiveness 1163 MachineOperandIteratorBase::PhysRegInfo Analysis = 1164 ConstMIOperands(I).analyzePhysReg(Reg, TRI); The instruction I being analyzed is: %BX<def> = MOV16rm %EDI, 2, %ECX, 0, %noreg; mem:LD2[%arrayidx98](tbaa=!18) and the Reg being passed in is 21, which is EBX. The result I get back for is: Analysis:...
