Required methods

fn of_fn_ptr(cx: &C, sig: PolyFnSig<'tcx>, extra_args: &[Ty<'tcx>]) -> Self

Compute a FnAbi suitable for indirect calls, i.e. to fn pointers.

NB: this doesn’t handle virtual calls - those should use FnAbi::of_instance instead, where the instance is an InstanceDef::Virtual.

fn of_instance(
    cx: &C,
    instance: Instance<'tcx>,
    extra_args: &[Ty<'tcx>]
) -> Self

Compute a FnAbi suitable for declaring/defining an fn instance, and for direct calls to an fn.

NB: that includes virtual calls, which are represented by “direct calls” to an InstanceDef::Virtual instance (of <dyn Trait as Trait>::fn).

fn new_internal(
    cx: &C,
    sig: PolyFnSig<'tcx>,
    extra_args: &[Ty<'tcx>],
    caller_location: Option<Ty<'tcx>>,
    codegen_fn_attr_flags: CodegenFnAttrFlags,
    make_self_ptr_thin: bool
) -> Self

fn adjust_for_abi(&mut self, cx: &C, abi: SpecAbi)
