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

[Chris Lattner]

Changes in directory llvm/tools/gccas:

gccas.cpp updated: 1.85 -> 1.86

---
Log message:

Reorder passes a bit.  In particular, it makes sense to run globaldce IMMEDIATELY after funcresolve.  Also, run the mem2reg pass _early_ so that IPCP and DAE actually do stuff.
Run instcombine and simplify cfg after this to cleanup the intraprocedural messes we create.
