Documentation
virtualRegSqueeze :: RegClass -> VirtualReg -> Int Source #
regSqueeze_class reg Calculate the maximum number of register colors that could be denied to a node of this class due to having this reg as a neighbour.
classOfRealReg :: RealReg -> RegClass Source #
allRealRegs :: [RealReg] Source #
All the allocatable registers in the machine, including register pairs.
allocatableRegs :: [RealReg] Source #
Produce the second-half-of-a-double register given the first half.
All the regs that the register allocator can allocate to, with the fixed use regs removed.
argRegs :: RegNo -> [Reg] Source #
The registers to place arguments for function calls, for some number of arguments.
allArgRegs :: [Reg] Source #
All all the regs that could possibly be returned by argRegs
callClobberedRegs :: [Reg] Source #
mkVirtualReg :: Unique -> Format -> VirtualReg Source #
Make a virtual reg with this format.
regDotColor :: RealReg -> SDoc Source #
