[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,
