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

maxSpillSlots :: DynFlags -> Int
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
