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

[Brian Gaeke]

Changes in directory reopt/lib/LightWtProfiling:

RuntimeOptimizations.cpp updated: 1.12 -> 1.13

---
Log message:

Always use a ModuleProvider.

Fix up some comments.

Set up a FunctionPassManager, a DefaultIntrinsicLowering, and a SPARC
TargetMachine; hopefully we can use all these instances in the rest of the
trace-opt machinery too.

Add commented-out code: we will want to addPassesToJITCompile soon. :-)
