[llvm-commits] CVS: llvm/lib/Target/CBackend/CTargetMachine.h

[Owen Anderson]

Changes in directory llvm/lib/Target/CBackend:

CTargetMachine.h updated: 1.10 -> 1.11
---
Log message:

Refactor TargetMachine, pushing handling of TargetData into the target-specific subclasses.  This has one caller-visible change: getTargetData() now returns a pointer instead of a reference.

This fixes PR 759: http://llvm.cs.uiuc.edu/PR759 .
