Documentation
showReg :: RegNo -> String
Get the standard name for the register with this number.
virtualRegSqueeze :: RegClass -> VirtualReg -> FastInt
regSqueeze_class reg Calculuate the maximum number of register colors that could be denied to a node of this class due to having this reg as a neighbour.
realRegSqueeze :: RegClass -> RealReg -> FastInt
classOfRealReg :: RealReg -> RegClass
allRealRegs :: [RealReg]
All the allocatable registers in the machine, including register pairs.
gReg :: Int -> RegNo
iReg :: Int -> RegNo
lReg :: Int -> RegNo
Get the regno for this sort of reg
oReg :: Int -> RegNo
fReg :: Int -> RegNo
fp :: Reg
sp :: Reg
g0 :: Reg
g1 :: Reg
Some specific regs used by the code generator.

allocatableRegs :: [RealReg]
Produce the second-half-of-a-double register given the first half. All the regs that the register allocator can allocate to, with the the fixed use regs removed.
get_GlobalReg_reg_or_addr :: GlobalReg -> Either RealReg CmmExpr
argRegs :: RegNo -> [Reg]
The registers to place arguments for function calls, for some number of arguments.
allArgRegs :: [Reg]
All all the regs that could possibly be returned by argRegs
callClobberedRegs :: [Reg]
mkVirtualReg :: Unique -> Size -> VirtualReg
Make a virtual reg with this size.
regDotColor :: RealReg -> SDoc
