Thanks for your advice. But I have searched X86 and find no more information than I have known. The problem is not to create a MachineMemOperand, but to create a MachineMemOperand with certain address. This scene does not exist in the original code. Since I have to do this in the process of register allocating, inserting IR instruction seems to be infeasible. I have thought of storing the address

...oc DL; if (MI != MBB.end()) DL = MI->getDebugLoc(); MachineFunction &MF = *MBB.getParent(); MachineFrameInfo &MFI = *MF.getFrameInfo(); MachineMemOperand *MMO = MF.getMachineMemOperand(PseudoSourceValue::getFixedStack(FrameIdx), MachineMemOperand::MOStore, 0, MFI.getObjectSize(FrameIdx), MFI.getObjectAlignment(FrameIdx)); unsigned tmpVReg = MF.getRegInfo().createVirtualRegister(OURTARGET::IntRegsRegisterClass); MachineInstr* mi = BuildMI(MBB, MI, DL, get(OURTARGET::ADDri), tmpVReg).addFram...

Hello, I've hit an assertion in SelectionDAG where we try to merge 2 loads that have the same operands but their MMO flags differ. One is dereferenceable and one is not. I'm not sure what the underlying issue here is: 1) MDSDNode with the same operands should have the same flags set on their respective MMO. The fact the flags differ when the opcode,types,operands and address-space are

Hi,   For a custom target, there is a pass to perform memory dependence analysis, where, i need to get memory pointer for "load instruction". I want to check the pointer alias behavior. I am getting this by considering the memoperands for the load instruction.   For "load instruction", Machine Instruction dumps as below:   vr12<def> = LD_Iri %vr2<kill>, 0;
