llvm-6502/lib/Target/MSP430/MSP430Subtarget.cpp
Evan Cheng 59ee62d241 - Eliminate MCCodeEmitter's dependency on TargetMachine. It now uses MCInstrInfo
and MCSubtargetInfo.
- Added methods to update subtarget features (used when targets automatically
  detect subtarget features or switch modes).
- Teach X86Subtarget to update MCSubtargetInfo features bits since the
  MCSubtargetInfo layer can be shared with other modules.
- These fixes .code 16 / .code 32 support since mode switch is updated in
  MCSubtargetInfo so MC code emitter can do the right thing.
