Enum optimization::Level

pub enum Level {
    None,
    Moderate,
    Aggressive,
    Custom(Vec<Optimization>),
}

These are predefined sequences of optimizations (in clang and gcc these are called -O1, -O3, -Os and so forth).

Variants

None

This level compiles the fastest and generates the most debuggable code since it does not perform any optimization.

Moderate

Moderate level of optimization which enables most optimizations.

Aggressive

Enables optimizations that take longer to perform or that may generate larger code in an attempt to make the program run faster.

Custom(Vec<Optimization>)

A user-defined sequence of optimizations

Methods

impl Level

pub fn run_all(&self, program: &mut FirmProgram)

run the list of optimizations defined by the optimization level on the given program

Trait Implementations

impl Clone for Level

fn clone(&self) -> Level

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Level

fn default() -> Self

Returns the "default value" for a type.

impl Debug for Level

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

Formats the value using the given formatter.
