Enum OpcodeSelector

enum OpcodeSelector {
    Normal,
    ImmediateSrc,
    Mul,
    WideMul,
    Target,
    Branch,
}

HashX uses a limited number of different instruction selection strategies, chosen based on the sub-cycle timing of our position in the instruction stream.

Variants

Normal

Main ALU instruction chooser, picks from Add/Sub/Xor/Rotate

ImmediateSrc

Retry pass if Normal fails, instructions with immediate source only

Mul

Only multiply instructions, no additional register selection work.

WideMul

Wide multiply instructions, randomly choosing signedness

Target

Only branch targets

Branch

Only branch instructions

Implementations

impl OpcodeSelector

fn apply<R: RngCore>(&self, gen: &mut Generator<'_, R>) -> Opcode

Apply the selector, advancing the Rng state and returning an Opcode.

Trait Implementations

impl Clone for OpcodeSelector

fn clone(&self) -> OpcodeSelector

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OpcodeSelector

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

Formats the value using the given formatter.

impl PartialEq for OpcodeSelector

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

Tests for self and other values to be equal, and is used by ==.

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

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