[llvm-commits] CVS: llvm/lib/Target/X86/X86TargetMachine.cpp

[Chris Lattner]

Changes in directory llvm/lib/Target/X86:

X86TargetMachine.cpp updated: 1.74 -> 1.75
---
Log message:

Allow the selection-dag based selector to be diabled with -disable-pattern-isel.

For now, this is the default, as the current selector is missing some big pieces.
To enable the new selector, pass -disable-pattern-isel=false to llc or lli.
