Documentation
Check if a RI represents a zero value. - a literal zero - register %g0, which is always zero.
fpRelEA :: Int -> Reg -> InstrSource
Calculate the effective address which would be used by the corresponding fpRel sequence.
isUnconditionalJump :: Instr -> BoolSource
An instruction that will cause the one after it never to be exectuted
SPARC instruction set. Not complete. This is only the ones we need.

The maximum number of spill slots available on the C stack. If we use up all of the slots, then we're screwed.
Why do we reserve 64 bytes, instead of using the whole thing?? -- BL 20090215
