[llvm-commits] CVS: reopt/lib/LightWtProfiling/UnpackTraceFunction.cpp

[Brian Gaeke]

Changes in directory reopt/lib/LightWtProfiling:

UnpackTraceFunction.cpp updated: 1.36 -> 1.37

---
Log message:

Try looking for special "operand 0" records in PhyRegAlloc saved state.
#if 0-out getSavedStateIndexOfOperandInInstruction() for now so that we
make sure we don't call it.
