[LLVMdev] Coalescing and VNInfo
I've hit a bug in a refactored version of coalescing and I'm trying to
understand what is going on. In particular, I'm curious about this
line in SimpleRegisterCoalescing.cpp:
00710 LHSValsDefinedFromRHS[VNI] =
RHS.getLiveRangeContaining(VNI->def-1)->valno;
Why VNI->def-1? The bug I'm seeing is that RHS returns a NULL
LiveRange because it doesn't contain VNI->def-1:
%reg1093,0 = [5750,5754:2)[5754,5782:1)[5782,5858:0)[5868,5870:0)
0 at 5782-(5858 5870) 1 at 5754-(5778) 2 at 5750
Should it really be VNI-...
