Documentation
type InstrBlock = OrdList Instr Source #
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 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 |
Holds code that references a memory address.
Constructors
| Amode AddrMode InstrBlock |
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

| Any Format (Reg -> InstrBlock) |
