ghc/compiler/nativeGen RegisterAlloc.hs
Log:
PowerPC NCG:
Add more efficient code for FreeRegs. One Word32 for the integer regs and
one Word32 for the floating point regs is faster than one Word64 for both.
Also, on PowerPC, use higher-numbered registers first because they aren't
clobbered by function calls.
