Trait Implementations

impl Debug for ConstantP

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

Formats the value using the given formatter.

impl Pass for ConstantP

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

What it is called, in lower case with hyphens between words.

fn describe(&self) -> &'static str

One line, for --print-pipeline.

fn preserves(&self) -> Preserved

Which analyses still answer the same questions about the function this pass has finished with as they did about the one it was handed.

fn required(&self) -> bool

Whether -fno-<name> is refused, because the pass is not one the compile can do without.

fn run(&self, func: &mut Func, _an: &mut Analyses, _fuel: &mut Fuel) -> Stats

Transforms the function, asking fuel before each transformation.

fn run_emitting( &self, func: &mut Func, an: &mut Analyses, fuel: &mut Fuel, data: &mut ReadOnly<'_>, ) -> Stats

Transforms the function the way Pass::run does, with somewhere to put a read only table the transformation needs.
