[llvm-commits] CVS: llvm/include/llvm/Target/TargetMachine.h

[Chris Lattner]

Changes in directory llvm/include/llvm/Target:

TargetMachine.h updated: 1.44 -> 1.45

---
Log message:

Delete the V9 specific findOptimalStorageSize method, inlining it into all callers.
Substantially clean up all target implementations by having the OPTIONAL get*Info
methods return a pointer instead of a reference.  This allows us to have default
implementations!
