Fields

name: String

Instruction mnemonic, also becomes opcode name.

camel_name: String

doc: String

Documentation string.

operands_in: Vec<Operand>

Input operands. This can be a mix of SSA value operands and other operand kinds.

operands_out: Vec<Operand>

Output operands. The output operands must be SSA values or variable_args.

format: Rc<InstructionFormat>

Instruction format.

polymorphic_info: Option<PolymorphicInfo>

One of the input or output operands is a free type variable. None if the instruction is not polymorphic, set otherwise.

value_opnums: Vec<usize>

Indices in operands_in of input operands that are values.

imm_opnums: Vec<usize>

Indices in operands_in of input operands that are immediates or entities.

value_results: Vec<usize>

Indices in operands_out of output operands that are values.

is_terminator: bool

True for instructions that terminate the block.

is_branch: bool

True for all branch or jump instructions.

is_call: bool

Is this a call instruction?

is_return: bool

Is this a return instruction?

can_load: bool

Can this instruction read from memory?

can_store: bool

Can this instruction write to memory?

can_trap: bool

Can this instruction cause a trap?

other_side_effects: bool

Does this instruction have other side effects besides can_* flags?

side_effects_idempotent: bool

Despite having other side effects, is this instruction okay to GVN?
