[llvm-commits] CVS: llvm/lib/Target/PowerPC/PowerPC.td Makefile PowerPCAsmPrinter.cpp

[Misha Brukman]

Changes in directory llvm/lib/Target/PowerPC:

PowerPC.td updated: 1.8 -> 1.9
Makefile updated: 1.11 -> 1.12
PowerPCAsmPrinter.cpp updated: 1.60 -> 1.61
---
Log message:

* Change PPC32AsmPrinter => PowerPCAsmPrinter since it is now shared between
  Darwin and AIX and is not 32- or 64-bit specific
* Bring back PowerPC.td as a result, to make it use the `PowerPC' class name
* Adjust Makefile accordingly
