[llvm-commits] CVS: llvm/lib/Target/X86/X86CodeEmitter.cpp X86TargetMachine.cpp

[Chris Lattner]

Changes in directory llvm/lib/Target/X86:

X86CodeEmitter.cpp updated: 1.44 -> 1.45
X86TargetMachine.cpp updated: 1.40 -> 1.41

---
Log message:

Finally, _actually delete the machine code_ for a function, after it has
been emitted.  Also, since the FPK pass is causing memory access violations,
disable it.
