Struct falcon::il::Block

pub struct Block { /* fields omitted */ }

A basic block in Falcon IL.

Methods

impl Block

pub fn address(&self) -> Option<u64>

Get the address of the first instruction in this block

pub fn append(&mut self, other: &Block)

Appends the contents of another Block to this Block.

Instruction indices are updated accordingly.

pub fn index(&self) -> usize

Returns the index of this Block

pub fn instructions(&self) -> &Vec<Instruction>

Returns instructions for this Block

pub fn instructions_mut(&mut self) -> &mut Vec<Instruction>

Returns a mutable reference to the instructions for this Block.

pub fn is_empty(&self) -> bool

Returns try if this Block is empty, meaning it has no Instruction

pub fn instruction(&self, index: usize) -> Option<&Instruction>

Returns an Instruction by index, or None if the instruction does not exist.

pub fn instruction_mut(&mut self, index: usize) -> Option<&mut Instruction>

Returns a mutable reference to an Instruction by index, or None if the Instruction does not exist.

pub fn remove_instruction(&mut self, index: usize) -> Result<()>

Deletes an Instruction by its index.

pub fn temp(&mut self, bits: usize) -> Scalar

Generates a temporary scalar unique to this block.

pub fn assign(&mut self, dst: Scalar, src: Expression)

Adds an assign operation to the end of this block.

pub fn store(&mut self, address: Expression, src: Expression)

Adds a store operation to the end of this block.

pub fn load(&mut self, dst: Scalar, address: Expression)

Adds a load operation to the end of this block.

pub fn branch(&mut self, dst: Expression)

Adds a conditional branch operation to the end of this block.

pub fn intrinsic(&mut self, intrinsic: Intrinsic)

Adds an intrinsic operation to the end of this block.

pub fn nop(&mut self)

Adds a nop operation to the end of this block.

Trait Implementations

impl Clone for Block

fn clone(&self) -> Block

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Block

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

Formats the value using the given formatter.

impl Eq for Block

impl Hash for Block

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,

Feeds a slice of this type into the given [Hasher].

impl Ord for Block

fn cmp(&self, other: &Block) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

impl PartialEq for Block

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

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

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

This method tests for !=.

impl PartialOrd for Block

fn partial_cmp(&self, other: &Block) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Block) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Block) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Block) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Block) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Vertex for Block

fn index(&self) -> usize

fn dot_label(&self) -> String

impl Display for Block

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

Formats the value using the given formatter.
