[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,
