Implementations

impl Opcode

pub fn is_terminator(self) -> bool

True for instructions that terminate the block

pub fn is_branch(self) -> bool

True for all branch or jump instructions.

pub fn is_call(self) -> bool

Is this a call instruction?

pub fn is_return(self) -> bool

Is this a return instruction?

pub fn can_load(self) -> bool

Can this instruction read from memory?

pub fn can_store(self) -> bool

Can this instruction write to memory?

pub fn can_trap(self) -> bool

Can this instruction cause a trap?

pub fn other_side_effects(self) -> bool

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

pub fn side_effects_idempotent(self) -> bool

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

pub fn all() -> &'static [Opcode]

All cranelift opcodes.

impl Opcode

pub fn format(self) -> InstructionFormat

Get the instruction format for this opcode.

pub fn constraints(self) -> OpcodeConstraints

Get the constraint descriptor for this opcode. Panic if this is called on NotAnOpcode.

pub fn is_safepoint(self) -> bool

Is this instruction a GC safepoint?

Safepoints are all kinds of calls, except for tail calls.

Trait Implementations
