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

[Brian Gaeke]

Changes in directory reopt/lib/LightWtProfiling:

UnpackTraceFunction.cpp updated: 1.74 -> 1.75

---
Log message:

Remove insertCopyMachineInstrs(), which is no longer called.

Something like it will be needed in the future, but this is just not
quite how it will need to be implemented, and in the meantime, we go
for simplicity.
