[llvm-commits] CVS: llvm/tools/gccas/gccas.cpp

[Chris Lattner]

Changes in directory llvm/tools/gccas:

gccas.cpp updated: 1.123 -> 1.124
---
Log message:

Run an instcombine pass after inlining but before scalarrepl.  This allows 
instcombine to clean up the code, which makes more code suitable for SRoA.
This helps C++ code in particular, e.g. speeding up tramp3d by 31%.
