[llvm-commits] CVS: llvm/tools/gccld/GenerateCode.cpp

[Chris Lattner]

Changes in directory llvm/tools/gccld:

GenerateCode.cpp updated: 1.19 -> 1.20

---
Log message:

We have this snazzy link-time optimizer.  How about we start using it?  This
removes some cruft from 255.vortex, cleaning up after DAE and IPCP, which
do horrible, beautiful, things to vortex.
