Changes in directory llvm/lib/Target/PowerPC:
PPCISelDAGToDAG.cpp updated: 1.126 -> 1.127
PPCISelLowering.cpp updated: 1.39 -> 1.40
---
Log message:
When lowering direct calls, lower them to use a targetglobaladress directly
instead of a globaladdress. This has no effect on the generated code at all.
