Trait Implementations§

Source§

impl Clone for MInst

Source§

fn clone(&self) -> MInst

Returns a copy of the value. Read more
1.0.0 · Source§

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source. Read more
Source§

impl Debug for Inst

Source§

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter. Read more
Source§

impl MachInst for Inst

Source§

const TRAP_OPCODE: &'static [u8] = _

Byte representation of a trap opcode which is inserted by MachBuffer during its defer_trap method.
Source§

type ABIMachineSpec = X64ABIMachineSpec

The ABI machine spec for this MachInst.
Source§

type LabelUse = LabelUse

A label-use kind: a type that describes the types of label references that can occur in an instruction.
Source§

fn get_operands(&mut self, collector: &mut impl OperandVisitor)

Return the registers referenced by this machine instruction along with the modes of reference (use, def, modify).
Source§

fn is_move(&self) -> Option<(Writable<Reg>, Reg)>

If this is a simple move, return the (source, destination) tuple of registers.
Source§

fn is_included_in_clobbers(&self) -> bool

Should this instruction be included in the clobber-set?
Source§

fn is_trap(&self) -> bool

Is this an unconditional trap?
Source§

fn is_args(&self) -> bool

Is this an “args” pseudoinst?
Source§

fn is_term(&self) -> MachTerminator

Is this a terminator (branch or ret)? If so, return its type (ret/uncond/cond) and target if applicable.
Source§

fn is_mem_access(&self) -> bool

Does this instruction access memory?
Source§

fn gen_move(dst_reg: Writable<Reg>, src_reg: Reg, ty: Type) -> Inst

Generate a move.
Source§

fn gen_nop(preferred_size: usize) -> Inst

Generate a NOP. The preferred_size parameter allows the caller to request a NOP of that size, or as close to it as possible. The machine backend may return a NOP whose binary encoding is smaller than the preferred size, but must not return a NOP that is larger. However, the instruction must have a nonzero size if preferred_size is nonzero.
Source§

fn rc_for_type( ty: Type, ) -> CodegenResult<(&'static [RegClass], &'static [Type])>

Determine register class(es) to store the given Cranelift type, and the Cranelift type actually stored in the underlying register(s). May return an error if the type isn’t supported by this backend. Read more
Source§

fn canonical_type_for_rc(rc: RegClass) -> Type

Get an appropriate type that can fully hold a value in a given register class. This may not be the only type that maps to that class, but when used with gen_move() or the ABI trait’s load/spill constructors, it should produce instruction(s) that move the entire register contents.
Source§

fn gen_jump(label: MachLabel) -> Inst

Generate a jump to another target. Used during lowering of control flow.
Source§

fn gen_imm_u64(value: u64, dst: Writable<Reg>) -> Option<Self>

Generate a store of an immediate 64-bit integer to a register. Used by the control plane to generate random instructions.
Source§

fn gen_imm_f64( value: f64, tmp: Writable<Reg>, dst: Writable<Reg>, ) -> SmallVec<[Self; 2]>

Generate a store of an immediate 64-bit integer to a register. Used by the control plane to generate random instructions. The tmp register may be used by architectures which don’t support writing immediate values to floating point registers directly.
Source§

fn gen_dummy_use(reg: Reg) -> Self

Generate a dummy instruction that will keep a value alive but has no other purpose.
Source§

fn worst_case_size() -> CodeOffset

What is the worst-case instruction size emitted by this instruction type?
Source§

fn ref_type_regclass(_: &Flags) -> RegClass

What is the register class used for reference types (GC-observable pointers)? Can be dependent on compilation flags.
Source§

fn is_safepoint(&self) -> bool

Is this a safepoint?
Source§

fn function_alignment() -> FunctionAlignment

Returns a description of the alignment required for functions for this architecture.
Source§

fn align_basic_block(offset: CodeOffset) -> CodeOffset

Align a basic block offset (from start of function). By default, no alignment occurs.
Source§

fn gen_block_start( _is_indirect_branch_target: bool, _is_forward_edge_cfi_enabled: bool, ) -> Option<Self>

Generate an instruction that must appear at the beginning of a basic block, if any. Note that the return value must not be subject to register allocation.
Source§

impl MachInstEmit for Inst

Source§

type State = EmitState

Persistent state carried across emit invocations.
Source§

type Info = EmitInfo

Constant information used in emit invocations.
Source§

fn emit( &self, sink: &mut MachBuffer<Inst>, info: &Self::Info, state: &mut Self::State, )

Emit the instruction.
Source§

fn pretty_print_inst(&self, _: &mut Self::State) -> String

Pretty-print the instruction.
Source§

impl MachInstEmitState<MInst> for EmitState

Source§

fn new(abi: &Callee<X64ABIMachineSpec>, ctrl_plane: ControlPlane) -> Self

Create a new emission state given the ABI object.
Source§

fn pre_safepoint(&mut self, user_stack_map: Option<UserStackMap>)

Update the emission state before emitting an instruction that is a safepoint.
Source§

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.
Source§

fn take_ctrl_plane(self) -> ControlPlane

Used to continue using a control plane after the emission state is not needed anymore.
Source§

fn frame_layout(&self) -> &FrameLayout

The [FrameLayout] for the function currently being compiled.
Source§

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.
