We have an unfortunate situation in our back end where we have to keep pairs of
functions synchronized. Needless to say that this is not an ideal situation as
it is very difficult to enforce. Even without bugs, it's annoying to have to do
the same thing in two places.
This patch just refactors the code so that the two pairs of those functions that
pertain to printing register operands are unified:
- stripRegisterPrefix() - this just removes the letter prefixes from registers
for the InstrPrinter and AsmPrinter. This patch provides this as a static
member of PPCRegisterInfo
- Handling of PPCII::UseVSXReg - there are 3 places where we do something
special for instructions with that flag set. Each of those places does its
own checking of this flag and implements code customization. Any changes to
how we print/encode VSX/VMX registers require modifying all 3 places. This
patch unifies this into a static function in PPCInstrInfo that returns the
register number adjusted as needed.
