Implementations§

source§

impl<B: WriteBackendMethods> LtoModuleCodegen<B>

source

pub fn name(&self) -> &str

source

pub unsafe fn optimize( self, cgcx: &CodegenContext<B>, ) -> Result<ModuleCodegen<B::Module>, FatalError>

Optimize this module within the given codegen context.

This function is unsafe as it’ll return a ModuleCodegen still points to LLVM data structures owned by this LtoModuleCodegen. It’s intended that the module returned is immediately code generated and dropped, and then this LTO module is dropped.

source

pub fn cost(&self) -> u64

A “gauge” of how costly it is to optimize this module, used to sort biggest modules first.
