archWordFormat :: Bool -> Format Source #
stackFrameHeaderSize :: Platform -> Int Source #
The size of a minimal stackframe header including minimal parameter save area.
maxSpillSlots :: NCGConfig -> Int Source #
The number of spill slots available without allocating more.
allocMoreStack :: Platform -> Int -> NatCmmDecl statics Instr -> UniqSM (NatCmmDecl statics Instr, [(BlockId, BlockId)]) Source #
makeFarBranches :: LabelMap RawCmmStatics -> [NatBasicBlock Instr] -> [NatBasicBlock Instr] Source #
mkJumpInstr :: BlockId -> [Instr] Source #
Make an unconditional jump instruction.
mkSpillInstr :: NCGConfig -> Reg -> Int -> Int -> [Instr] Source #
An instruction to spill a register into a spill slot.
patchJumpInstr :: Instr -> (BlockId -> BlockId) -> Instr Source #
Change the destination of this jump instruction. Used in the linear allocator when adding fixup blocks for join points.
patchRegsOfInstr :: Instr -> (Reg -> Reg) -> Instr Source #
Apply a given mapping to all the register references in this instruction.
jumpDestsOfInstr :: Instr -> [BlockId] Source #
Checks whether this instruction is a jump/branch instruction. One that can change the flow of control in a way that the register allocator needs to worry about.
takeRegRegMoveInstr :: Instr -> Maybe (Reg, Reg) Source #
Take the source and destination from this reg -> reg move instruction or Nothing if it's not one
takeDeltaInstr :: Instr -> Maybe Int Source #
See if this instruction is telling us the current C stack delta
mkRegRegMoveInstr :: Reg -> Reg -> Instr Source #
Copy the value in a register to another one. Must work for all register classes.
regUsageOfInstr :: Platform -> Instr -> RegUsage Source #
Get the registers that are being used by this instruction. regUsage doesn't need to do any trickery for jumps and such. Just state precisely the regs read and written by that insn. The consequences of control flow transfers, as far as register allocation goes, are taken care of by the register allocator.
isJumpishInstr :: Instr -> Bool Source #
Checks whether this instruction is a jump/branch instruction. One that can change the flow of control in a way that the register allocator needs to worry about.
isMetaInstr :: Instr -> Bool Source #
