impl<'a, 'tcx> TerminatorCodegenHelper<'tcx>
sourcefn funclet<'b, Bx: BuilderMethods<'a, 'tcx>>(
&self,
fx: &'b mut FunctionCx<'a, 'tcx, Bx>
) -> Option<&'b Bx::Funclet>
fn funclet<'b, Bx: BuilderMethods<'a, 'tcx>>( &self, fx: &'b mut FunctionCx<'a, 'tcx, Bx> ) -> Option<&'b Bx::Funclet>
Returns the appropriate Funclet
for the current funclet, if on MSVC,
either already previously cached, or newly created, by landing_pad_for
.

target: BasicBlock
) -> Bx::BasicBlock
fn llbb_with_cleanup<Bx: BuilderMethods<'a, 'tcx>>( &self, fx: &mut FunctionCx<'a, 'tcx, Bx>, target: BasicBlock ) -> Bx::BasicBlock
Get a basic block (creating it if necessary), possibly with cleanup stuff in it or next to it.

Call fn_ptr
of fn_abi
with the arguments llargs
, the optional
return destination destination
and the unwind action unwind
.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
