Struct Instruction 

pub struct Instruction {
    pub word: usize,
    pub opcode: u16,
    pub control: u32,
    pub extensions: Vec<u32>,
    pub saturate: bool,
    pub nonzero: bool,
    pub operands: Vec<Operand>,
}

An instruction as stored.

Fields

word: usize

The instruction’s first word in the token stream.

opcode: u16

The opcode token’s low 11 bits (see opcode_name).

control: u32

The opcode token’s bits 11 to 23: saturate and the opcode-specific controls (the test of a conditional, a resinfo return type, the interpolation of a declaration).

extensions: Vec<u32>

The opcode’s extended tokens as stored (sample offsets, resource dimension, return type).

saturate: bool

The saturate bit of the opcode token.

nonzero: bool

A conditional (if, breakc, continuec) taken when its operand is nonzero (_nz), else when zero (_z).

operands: Vec<Operand>

The operands, destination first where the instruction has one.

Implementations

impl Instruction

pub fn name(&self) -> &'static str

The opcode’s name (mov, add, …), or unknown opcode.

pub fn sample_offset(&self) -> Option<[i32; 3]>

The sample offsets of the extended token of kind 1 (_aoffimmi), if the instruction has one.

pub fn resource_dimension(&self) -> Option<(u32, u32)>

The resource dimension and structured stride of the extended token of kind 2.

pub fn return_type(&self) -> Option<u32>

The return-type token of the extended token of kind 3 (four nibbles).

Trait Implementations

impl Clone for Instruction

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Instruction

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

Formats the value using the given formatter.
