[llvm-commits] CVS: llvm/lib/Target/X86/X86RegisterClasses.cpp X86RegisterInfo.h X86RegisterInfo.cpp

[Misha Brukman]

Changes in directory llvm/lib/Target/X86:

X86RegisterClasses.cpp added (r1.1)
X86RegisterInfo.h updated: 1.1 -> 1.2
X86RegisterInfo.cpp updated: 1.1 -> 1.2

---
Log message:

Add definitions for function headers from MRegisterInfo.h:
Some functions are in X86RegisterInfo.cpp, others, because of the data they
need, are in X86RegisterClasses.cpp, which also defines some register classes:
byte, short, and int.
