Required methods

pub fn new_metadata(&self, sess: TyCtxt<'_>, mod_name: &str) -> Self::Module[src]

pub fn write_compressed_metadata<'tcx>(
    &self,
    tcx: TyCtxt<'tcx>,
    metadata: &EncodedMetadata,
    llvm_module: &mut Self::Module
)[src]

pub fn codegen_allocator<'tcx>(
    &self,
    tcx: TyCtxt<'tcx>,
    mods: &mut Self::Module,
    kind: AllocatorKind,
    has_alloc_error_handler: bool
)[src]

pub fn compile_codegen_unit(
    &self,
    tcx: TyCtxt<'_>,
    cgu_name: Symbol
) -> (ModuleCodegen<Self::Module>, u64)[src]

This generates the codegen unit and returns it along with a u64 giving an estimate of the unit's processing cost.

pub fn target_machine_factory(
    &self,
    sess: &Session,
    opt_level: OptLevel
) -> Arc<dyn Fn() -> Result<Self::TargetMachine, String> + Send + Sync>[src]

pub fn target_cpu<'b>(&self, sess: &'b Session) -> &'b str[src]

pub fn tune_cpu<'b>(&self, sess: &'b Session) -> Option<&'b str>[src]
