[−][src]Struct cranelift_codegen_meta::cdsl::recipes::EncodingRecipe
A recipe for encoding instructions with a given format.
Many different instructions can be encoded by the same recipe, but they must all have the same instruction format.
The operands_in
and operands_out
arguments are tuples specifying the register
allocation constraints for the value operands and results respectively. The
possible constraints for an operand are:
- A
RegClass
specifying the set of allowed registers. - A
Register
specifying a fixed-register operand. - An integer indicating that this result is tied to a value operand, so they must use the same register.
- A
Stack
specifying a value in a stack slot.
The branch_range
argument must be provided for recipes that can encode
branch instructions. It is an (origin, bits)
tuple describing the exact
range that can be encoded in a branch instruction.
Fields
name: String
Short mnemonic name for this recipe.
format: Rc<InstructionFormat>
Associated instruction format.
base_size: u64
Base number of bytes in the binary encoded instruction.
operands_in: Vec<OperandConstraint>
Tuple of register constraints for value operands.
operands_out: Vec<OperandConstraint>
Tuple of register constraints for results.
compute_size: &'static str
Function name to use when computing actual size.
branch_range: Option<BranchRange>
(origin, bits)
range for branches.
clobbers_flags: bool
This instruction clobbers iflags
and fflags
; true by default.
inst_predicate: Option<InstructionPredicate>
Instruction predicate.
isa_predicate: Option<u8>
ISA predicate.
emit: Option<String>
Rust code for binary emission.
