Struct Cranelift

pub struct Cranelift { /* private fields */ }

Global configuration options used to create an wasmer_engine::Engine and customize its behavior.

This structure exposes a builder-like interface and is primarily consumed by wasmer_engine::Engine::new.

Implementations

impl Cranelift

pub fn new() -> Self

Creates a new configuration object with the default configuration specified.

pub fn canonicalize_nans(&mut self, enable: bool) -> &mut Self

Enable NaN canonicalization.

NaN canonicalization is useful when trying to run WebAssembly deterministically across different architectures.

pub fn opt_level(&mut self, opt_level: CraneliftOptLevel) -> &mut Self

The optimization levels when optimizing the IR.

pub fn isa(&self, target: &Target) -> CodegenResult<Box<dyn TargetIsa>>

Generates the ISA for the provided target

pub fn flags(&self, target: &Target) -> Flags

Generates the flags for the compiler
