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

Changes in directory llvm/lib/Target/X86:

Printer.cpp updated: 1.46 -> 1.47
X86.h updated: 1.13 -> 1.14
X86TargetMachine.cpp updated: 1.18 -> 1.19

---
Log message:

Printer.cpp: Ditch addRequired/getAnalysis, because they leave
  Printer::doFinalization() out in the cold.  Now we pass in a TargetMachine
  to Printer's constructor and get the TargetData from the TargetMachine.
 Don't pass TargetMachine or MRegisterInfo objects around in the Printer.
 Constify TargetData references.
X86.h: Update comment and prototype of createX86CodePrinterPass().
X86TargetMachine.cpp: Update callers of createX86CodePrinterPass().
