stackFrameHeaderSize :: Int Source #
Stack frame header size Each stack frame contains ra and fp -- prologue.
spillSlotSize :: Int Source #
All registers are 8 byte wide.
stackAlign :: Int Source #
The number of bytes that the stack pointer should be aligned to.
maxSpillSlots :: NCGConfig -> Int Source #
The number of spill slots available without allocating more.
spillSlotToOffset :: Int -> Int Source #
Convert a spill slot number to a *byte* offset.
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.
callerSavedRegisters :: [Reg] Source #
Caller-saved registers (according to calling convention)
0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 |

patchRegsOfInstr :: Instr -> (Reg -> Reg) -> Instr Source #
Apply a given mapping to all the register references in this instruction.
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.
patchJumpInstr :: Instr -> (BlockId -> BlockId) -> Instr Source #
Change the destination of this (potential) jump instruction. Used in the linear allocator when adding fixup blocks for join points.
mkSpillInstr :: HasCallStack => NCGConfig -> RegWithFormat -> Int -> Int -> [Instr] Source #
Make a spill instruction, spill a register into spill slot.
mkLoadInstr :: NCGConfig -> RegWithFormat -> Int -> Int -> [Instr] Source #
Make a reload instruction, reload from spill slot to a register.
takeDeltaInstr :: Instr -> Maybe Int Source #
See if this instruction is telling us the current C stack delta
isMetaInstr :: Instr -> Bool Source #
Not real instructions. Just meta data
mkRegRegMoveInstr :: Reg -> Reg -> Instr Source #
Copy the value in a register to another one. Must work for all register classes.
takeRegRegMoveInstr :: Instr -> Maybe (Reg, Reg) Source #
Take the source and destination from this (potential) reg -> reg move instruction
We have to be a bit careful here: A MOV can also mean an implicit
conversion. This case is filtered out.
mkJumpInstr :: BlockId -> [Instr] Source #
Make an unconditional jump instruction.
allocMoreStack :: Platform -> Int -> NatCmmDecl statics Instr -> UniqDSM (NatCmmDecl statics Instr, [(BlockId, BlockId)]) Source #
