[LLVMdev] Pass to compute livein info
Hi all,
Is there a pass that computes livein information for each
MachineBasicBlock? I tried to find such a pass but could not find any. I
am trying to use the livein information to get dead registers to insert
some instructions right before code emission but the livein information
seems to be invalidated by some pass. I might need to recompute the
livein information before my pass. Thanks a
