Implementations

impl<B: WriteBackendMethods> LtoModuleCodegen<B>

pub fn name(&self) -> &str

pub unsafe fn optimize(
    &mut 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.

pub fn cost(&self) -> u64

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

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
