...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: {Clobbers = true, Defines = true, Reads = false, ReadsOverlap = false, DefinesDead = false, Kills = false} It seems based on the comment in the definition of PhysRegInfo.Defines, that Defines s...
