This removes some duplicated classes and definitions.
These instructions are defined:
_e32 // pseudo
_e32_si
_e64 // pseudo
_e64_si
_e64_vi
llvm-svn: 226191
Use VGPR_32 register class instead. These two register classes were
identical and having separate classes was causing
SIInstrInfo::isLegalOperands() to be overly conservative in some cases.
This change is necessary to prevent future paches from missing a folding
opportunity in fneg-fabs.ll.
