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

[Brian Gaeke]

Changes in directory reopt/lib/LightWtProfiling:

RuntimeOptimizations.cpp updated: 1.33 -> 1.34

---
Log message:

When writing out a trace, also write out the module into a separate file.
This allows us to test trace-based optimizations based on exactly what the
trace optimizer would get as input.

Diffs of the changes:  (+17 -7)
