Hello, I have written following code to check each register if it is used by machineFunction or not : MachineRegisterInfo *MRI = &MF.getRegInfo(); TargetRegisterInfo *TRI = (TargetRegisterInfo *)MF.getSubtarget().getRegisterInfo(); const TargetMachine &TM = MF.getTarget(); const MCRegisterInfo *MCRI = TM.getMCRegisterInfo(); DEBUG(dbgs() << "Function Name : " <<

Yes there is also MachineRegisterInfo::UsedPhysRegMask which should be the union of all regmasks in the function. > On May 11, 2016, at 10:47 AM, Hal Finkel via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > > > From: "Matthias Braun" <matze at braunis.de> > To: "Hal Finkel" <hfinkel at anl.gov> > Cc: "vivek pandya"

Hello Mentors, I did analyze assembly files generated for IPRA + PGO. (1) I observed that I did not considered the scope of the optimization so changing callee saved register set for non local function is bad because IPRA can not pass this information to other modules. (2) applying this change to indirect function also has no effect because for such case IPRA is currently not able to propagate

The code in X86TargetLowering::IsEligibleForTailCallOptimization() has this part: // The callee has to preserve all registers the caller needs to preserve. const X86RegisterInfo *TRI = Subtarget.getRegisterInfo(); const uint32_t *CallerPreserved = TRI->getCallPreservedMask(MF, CallerCC); if (!CCMatch) { const uint32_t *CalleePreserved = TRI->getCallPreservedMask(MF, CalleeCC);
