pub struct FaerieBuilder { /* fields omitted */ }

A builder for FaerieBackend.

Methods

impl FaerieBuilder

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

Create a new FaerieBuilder using the given Cranelift target, that can be passed to Module::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 cranelift_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 cranelift_module::default_libcall_names().
