Changes in directory llvm/lib/Target/PowerPC:
PPCTargetMachine.cpp updated: 1.76 -> 1.77
PPCTargetMachine.h updated: 1.15 -> 1.16
---
Log message:
Add a new option to indicate we want the code generator to emit code quickly,
not spending tons of time microoptimizing it. This is useful for an -O0
style of build.
