pub struct EmitState { /* private fields */ }
Expand description
State carried between emissions of a sequence of instructions.
Trait Implementations§
§impl MachInstEmitState<MInst> for EmitState
impl MachInstEmitState<MInst> for EmitState
§fn new(abi: &Callee<X64ABIMachineSpec>, ctrl_plane: ControlPlane) -> EmitState
fn new(abi: &Callee<X64ABIMachineSpec>, ctrl_plane: ControlPlane) -> EmitState
Create a new emission state given the ABI object.
§fn pre_safepoint(&mut self, user_stack_map: Option<UserStackMap>)
fn pre_safepoint(&mut self, user_stack_map: Option<UserStackMap>)
Update the emission state before emitting an instruction that is a
safepoint.
§fn ctrl_plane_mut(&mut self) -> &mut ControlPlane
fn ctrl_plane_mut(&mut self) -> &mut ControlPlane
The emission state holds ownership of a control plane, so it doesn’t
have to be passed around explicitly too much.
ctrl_plane_mut
may
be used if temporary access to the control plane is needed by some
other function that doesn’t have access to the emission state.§fn take_ctrl_plane(self) -> ControlPlane
fn take_ctrl_plane(self) -> ControlPlane
Used to continue using a control plane after the emission state is
not needed anymore.
§fn frame_layout(&self) -> &FrameLayout
fn frame_layout(&self) -> &FrameLayout
The [
FrameLayout
] for the function currently being compiled.§fn on_new_block(&mut self)
fn on_new_block(&mut self)
A hook that triggers when first emitting a new block.
It is guaranteed to be called before any instructions are emitted.
