Trait Implementations§
§impl MachInst for MInst
impl MachInst for MInst
§const TRAP_OPCODE: &'static [u8] = _
const TRAP_OPCODE: &'static [u8] = _
Byte representation of a trap opcode which is inserted by
MachBuffer
during its defer_trap
method.§type ABIMachineSpec = X64ABIMachineSpec
type ABIMachineSpec = X64ABIMachineSpec
The ABI machine spec for this
MachInst
.§type LabelUse = LabelUse
type LabelUse = LabelUse
A label-use kind: a type that describes the types of label references that
can occur in an instruction.
§fn get_operands(&mut self, collector: &mut impl OperandVisitor)
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).
§fn is_move(&self) -> Option<(Writable<Reg>, Reg)>
fn is_move(&self) -> Option<(Writable<Reg>, Reg)>
If this is a simple move, return the (source, destination) tuple of registers.
§fn is_included_in_clobbers(&self) -> bool
fn is_included_in_clobbers(&self) -> bool
Should this instruction be included in the clobber-set?
§fn is_term(&self) -> MachTerminator
fn is_term(&self) -> MachTerminator
Is this a terminator (branch or ret)? If so, return its type
(ret/uncond/cond) and target if applicable.
§fn is_mem_access(&self) -> bool
fn is_mem_access(&self) -> bool
Does this instruction access memory?
§fn gen_nop(preferred_size: usize) -> MInst
fn gen_nop(preferred_size: usize) -> MInst
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.§fn rc_for_type(
ty: Type,
) -> Result<(&'static [RegClass], &'static [Type]), CodegenError>
fn rc_for_type( ty: Type, ) -> Result<(&'static [RegClass], &'static [Type]), CodegenError>
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
§fn canonical_type_for_rc(rc: RegClass) -> Type
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.§fn gen_jump(label: MachLabel) -> MInst
fn gen_jump(label: MachLabel) -> MInst
Generate a jump to another target. Used during lowering of
control flow.
§fn gen_imm_u64(value: u64, dst: Writable<Reg>) -> Option<MInst>
fn gen_imm_u64(value: u64, dst: Writable<Reg>) -> Option<MInst>
Generate a store of an immediate 64-bit integer to a register. Used by
the control plane to generate random instructions.
§fn gen_imm_f64(
value: f64,
tmp: Writable<Reg>,
dst: Writable<Reg>,
) -> SmallVec<[MInst; 2]>
fn gen_imm_f64( value: f64, tmp: Writable<Reg>, dst: Writable<Reg>, ) -> SmallVec<[MInst; 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.
§fn gen_dummy_use(reg: Reg) -> MInst
fn gen_dummy_use(reg: Reg) -> MInst
Generate a dummy instruction that will keep a value alive but
has no other purpose.
§fn worst_case_size() -> u32
fn worst_case_size() -> u32
What is the worst-case instruction size emitted by this instruction type?
§fn ref_type_regclass(_: &Flags) -> RegClass
fn ref_type_regclass(_: &Flags) -> RegClass
What is the register class used for reference types (GC-observable pointers)? Can
be dependent on compilation flags.
§fn is_safepoint(&self) -> bool
fn is_safepoint(&self) -> bool
Is this a safepoint?
§fn function_alignment() -> FunctionAlignment
fn function_alignment() -> FunctionAlignment
Returns a description of the alignment required for functions for this
architecture.
§fn align_basic_block(offset: u32) -> u32
fn align_basic_block(offset: u32) -> u32
Align a basic block offset (from start of function). By default, no
alignment occurs.
§fn gen_block_start(
_is_indirect_branch_target: bool,
_is_forward_edge_cfi_enabled: bool,
) -> Option<Self>
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.
§impl MachInstEmit for MInst
impl MachInstEmit for MInst
§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.
