InstrBlocks are the insn sequences generated by the insn selectors. They are really trees of insns to facilitate fast appending, where a left-to-right traversal yields the insns in the correct order.

data CondCode

Source

Condition codes passed up the tree.

Constructors

CondCode Bool Cond InstrBlock

data ChildCode64

Source

a.k.a Register64 Reg is the lower 32-bit temporary which contains the result. Use getHiVRegFromLo to find the other VRegUnique.

Rules of this simplified insn selection game are therefore that the returned Reg may be modified

Constructors

ChildCode64 InstrBlock Reg

data Amode

Source

Holds code that references a memory address.

Constructors

Amode AddrMode InstrBlock

data Register

Source

Code to produce a result into a register. If the result must go in a specific register, it comes out as Fixed. Otherwise, the parent can decide which register to put it in.

Constructors

Fixed Size Reg InstrBlock
Any Size (Reg -> InstrBlock)

setSizeOfRegister :: Register -> Size -> Register

Source

Change the size field in a Register.

getRegisterReg :: CmmReg -> Reg

Source

Grab the Reg for a CmmReg

mangleIndexTree :: CmmExpr -> CmmExpr
