[LLVMdev] MachineMemOperand and dependence information
Sorry, this is the part in ARMLoadStoreOptimizer.cpp that creates a LDRD
instruction.
Ops.pop_back();
Ops.pop_back();
// Form the pair instruction.
if (isLd) {
MachineInstrBuilder MIB = BuildMI(*MBB, InsertPos,
dl, TII->get(NewOpc))
.addReg(EvenReg, RegState::Define)
.addReg(OddReg, RegState::Define)
.addReg(BaseReg);
if (!isT2)...

[LLVMdev] MachineMemOperand and dependence information
I have two questions regarding MachineMemOperands and dependence
information.
Q1) I noticed that MachineMemOperands are lost when two LDRs are combined
and a LDRD is generated in ARMPreAllocLoadStoreOpt:::RescheduleOps.
(before optimization)
%reg1033<def> = LDR %reg1030, %reg0, 4100, pred:14, pred:%reg0;
mem:LD4[%uglygep10]
%reg1054<def> = LDR %reg1030, %reg0, 4104, pred:14,
