Struct cretonne_faerie::FaerieBuilder

pub struct FaerieBuilder { /* fields omitted */ }

A builder for FaerieBackend.

Methods

impl FaerieBuilder

pub fn new(     isa: Box<TargetIsa>,     name: String,     collect_traps: FaerieTrapCollection,     libcall_names: Box<Fn(LibCall) -> String> ) -> ModuleResult<Self>

Create a new FaerieBuilder using the given Cretonne target, that can be passed to [Module::new](cretonne_module/struct.Module.html#method.new].

Faerie output requires that TargetIsa have PIC (Position Independent Code) enabled.

collect_traps setting determines whether trap information is collected in a FaerieTrapManifest available in the FaerieProduct.

The libcall_names function provides a way to translate cretonne_codegen's ir::LibCall enum to symbols. LibCalls are inserted in the IR as part of the legalization for certain floating point instructions, and for stack probes. If you don't know what to use for this argument, use FaerieBuilder::default_libcall_names().

pub fn default_libcall_names() -> Box<Fn(LibCall) -> String>

Default names for ir::LibCalls. A function by this name is imported into the object as part of the translation of a ir::ExternalName::LibCall variant. Calls to a LibCall should only be inserted into the IR by the cretonne_codegen legalizer pass.
