Implementations§

source§

impl<'a, 'tcx> TerminatorCodegenHelper<'tcx>

source

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.

source

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.

source

fn llbb_characteristics<Bx: BuilderMethods<'a, 'tcx>>( &self, fx: &mut FunctionCx<'a, 'tcx, Bx>, target: BasicBlock ) -> (bool, bool)

source

fn funclet_br<Bx: BuilderMethods<'a, 'tcx>>( &self, fx: &mut FunctionCx<'a, 'tcx, Bx>, bx: &mut Bx, target: BasicBlock, mergeable_succ: bool ) -> MergingSucc

source

fn do_call<Bx: BuilderMethods<'a, 'tcx>>( &self, fx: &mut FunctionCx<'a, 'tcx, Bx>, bx: &mut Bx, fn_abi: &'tcx FnAbi<'tcx, Ty<'tcx>>, fn_ptr: Bx::Value, llargs: &[Bx::Value], destination: Option<(ReturnDest<'tcx, Bx::Value>, BasicBlock)>, cleanup: Option<BasicBlock>, copied_constant_arguments: &[PlaceRef<'tcx, <Bx as BackendTypes>::Value>], mergeable_succ: bool ) -> MergingSucc

Call fn_ptr of fn_abi with the arguments llargs, the optional return destination destination and the cleanup function cleanup.

source

fn do_inlineasm<Bx: BuilderMethods<'a, 'tcx>>( &self, fx: &mut FunctionCx<'a, 'tcx, Bx>, bx: &mut Bx, template: &[InlineAsmTemplatePiece], operands: &[InlineAsmOperandRef<'tcx, Bx>], options: InlineAsmOptions, line_spans: &[Span], destination: Option<BasicBlock>, cleanup: Option<BasicBlock>, instance: Instance<'_>, mergeable_succ: bool ) -> MergingSucc

Generates inline assembly with optional destination and cleanup.
