Struct AddrTerm

pub struct AddrTerm {
    pub primary: AddrTermCalculation,
    pub second_use: Option<AddrTermCalculation>,
}

An address term, consisting of a primary sized shift-then-multipy operation, and an optional second sized shift-then-multiply operation.

Fields

primary: AddrTermCalculation

The primary operation on the input.

second_use: Option<AddrTermCalculation>

The optional second use of the input.

Implementations

impl AddrTerm

pub fn empty() -> Self

Creates a new address term that always returns 0.

pub fn identity() -> Self

Creates an address term that always returns the value it receives.

pub fn single(size: AddrTermSize, right: u8, mult: u8) -> Self

Creates an address term that sizes, shifts and multiplies once.

pub fn apply(self, val: u64) -> u64

Applies the term to val.

pub fn compute_relocation( self, current_value: u64, current_output: u64, target_output: u64, ) -> Option<u64>

Computes a new value for this term that would move the memory access from current_output to target_output, given that the input for the term is currently current_value.

pub fn offset_is_valid(self, offset: i64) -> bool

Returns true if the delta between two accesses where only this term differs can be offset.

pub fn minimum_step_size(self) -> u64

Returns the minimum step size of this term.

pub fn is_valid_delta( self, original_value: u64, new_value: u64, original_address: u64, new_address: u64, ) -> bool

Determines whether the change from original_address to new_address could have occurred given that the original value for this term was original_value, and for new_address it was new_value.

pub fn is_possible_with_delta( &self, original_address: u64, new_address: u64, ) -> bool

Determines whether this term could be part of an address calculation, if modifying only this term changes the address of a memory access from original_address to new_address.

pub fn all() -> Vec<AddrTerm>

Returns all supported AddrTerms.

Trait Implementations

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AddrTerm

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for AddrTerm

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

Formats the value using the given formatter.

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

impl Ord for AddrTerm

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

This method returns an Ordering between self and other.

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

where Self: Sized,
