analyzePhysReg question
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: {Clobbers = true, Defines = true, Reads = false, ReadsOv...
