Struct Instruction 

pub struct Instruction {
    pub op: Op,
    pub result: Option<(ValueId, TypeId)>,
    pub block: usize,
    pub at: usize,
    pub precise: bool,
}

An instruction of a function body.

Fields

op: Op

What it does.

result: Option<(ValueId, TypeId)>

The result’s value id and type, when the instruction produces one.

block: usize

The basic block it belongs to.

at: usize

Bit offset of its record.

precise: bool

The instruction carries the dx.precise attachment, which the compiler writes for HLSL’s precise: the value is not to be fused or reassociated. In skate.’s stock programs it is on calls only: 88,541 tertiary (mad), 13,005 loadInput, 3,546 unary, 1,421 dot3, 331 legacyF16ToF32, 307 binary, 213 dot4 and 105 dot2, in vertex programs (107,109 instructions in 3,185 of 3,341) and compute programs (360 in 12), in no pixel program; none of Elden Ring’s has it.

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.

impl PartialEq for Instruction

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

Equality operator ==.

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

Inequality operator !=.
