Implementations

impl InstructionData

pub fn opcode(&self) -> Opcode

Get the opcode of this instruction.

pub fn typevar_operand(&self, pool: &ValueListPool) -> Option<Value>

Get the controlling type variable operand.

pub fn arguments<'a>(&'a self, pool: &'a ValueListPool) -> &[Value]

Get the value arguments to this instruction.

pub fn arguments_mut<'a>( &'a mut self, pool: &'a mut ValueListPool ) -> &mut [Value]

Get mutable references to the value arguments to this instruction.

pub fn eq<F: Fn(Value) -> Value>( &self, other: &Self, pool: &ValueListPool, mapper: F ) -> bool

Compare two InstructionData for equality.

This operation requires a reference to a ValueListPool to determine if the contents of any ValueLists are equal.

This operation takes a closure that is allowed to map each argument value to some other value before the instructions are compared. This allows various forms of canonicalization.

pub fn hash<H: Hasher, F: Fn(Value) -> Value>( &self, state: &mut H, pool: &ValueListPool, mapper: F )

Hash an InstructionData.

This operation requires a reference to a ValueListPool to hash the contents of any ValueLists.

This operation takes a closure that is allowed to map each argument value to some other value before it is hashed. This allows various forms of canonicalization.

pub fn deep_clone(&self, pool: &mut ValueListPool) -> Self

Deep-clone an InstructionData, including any referenced lists.

This operation requires a reference to a ValueListPool to clone the ValueLists.

impl InstructionData

Analyzing an instruction.

Avoid large matches on instruction formats by using the methods defined here to examine instructions.

pub fn branch_destination<'a>( &'a self, jump_tables: &'a JumpTables ) -> &[BlockCall]

Get the destinations of this instruction, if it’s a branch.

br_table returns the empty slice.

pub fn branch_destination_mut<'a>( &'a mut self, jump_tables: &'a mut JumpTables ) -> &mut [BlockCall]

Get a mutable slice of the destinations of this instruction, if it’s a branch.

br_table returns the empty slice.

pub fn trap_code(&self) -> Option<TrapCode>

If this is a trapping instruction, get its trap code. Otherwise, return None.

pub fn cond_code(&self) -> Option<IntCC>

If this is a control-flow instruction depending on an integer condition, gets its condition. Otherwise, return None.

pub fn fp_cond_code(&self) -> Option<FloatCC>

If this is a control-flow instruction depending on a floating-point condition, gets its condition. Otherwise, return None.

pub fn trap_code_mut(&mut self) -> Option<&mut TrapCode>

If this is a trapping instruction, get an exclusive reference to its trap code. Otherwise, return None.

pub fn atomic_rmw_op(&self) -> Option<AtomicRmwOp>

If this is an atomic read/modify/write instruction, return its subopcode.

pub fn load_store_offset(&self) -> Option<i32>

If this is a load/store instruction, returns its immediate offset.

pub fn memflags(&self) -> Option<MemFlags>

If this is a load/store instruction, return its memory flags.

pub fn stack_slot(&self) -> Option<StackSlot>

If this instruction references a stack slot, return it

pub fn analyze_call<'a>(&'a self, pool: &'a ValueListPool) -> CallInfo<'a>

Return information about a call instruction.

Any instruction that can call another function reveals its call signature here.

Trait Implementations

impl Clone for InstructionData

fn clone(&self) -> InstructionData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InstructionData

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

Formats the value using the given formatter.

impl<'a> From<&'a InstructionData> for InstructionFormat

fn from(inst: &'a InstructionData) -> Self

Converts to this type from the input type.

impl Hash for InstructionData

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for InstructionData

fn eq(&self, other: &InstructionData) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
