Struct OpSpec 

pub struct OpSpec {
    pub name: &'static str,
    pub fmt: Fmt,
    pub opcode: u32,
    pub funct3: u32,
    pub aux: u32,
}

One implemented instruction: enough to encode it from operands.

Fields

name: &'static str

fmt: Fmt

opcode: u32

funct3: u32

aux: u32

funct7 (R / IShift32), funct6 (IShift), or funct12 (Unary).

Implementations

impl OpSpec

pub fn touches_memory_or_control(&self) -> bool

True for loads, stores, and branches — ops the (v1) register-only generator skips because they need a backing memory window or non-straight-line control flow. The rest (R/I/shift/unary/lui/auipc) are pure register→register and total by construction.

Trait Implementations

fn clone(&self) -> OpSpec

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

Performs copy-assignment from source.

impl Debug for OpSpec

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

Formats the value using the given formatter.
