[llvm-commits] CVS: llvm/lib/Target/PowerPC/PowerPCRegisterInfo.cpp

[Reid Spencer]

Changes in directory llvm/lib/Target/PowerPC:

PowerPCRegisterInfo.cpp updated: 1.24 -> 1.25
---
Log message:

Fix stack size processing now that the return address isn't an implied 
push onto the top of the stack like x86, which uses the local area 
offset.  This will allow the removal of PowerPCPEI.cpp soon.
