Struct rustc_codegen_ssa::mir::block::TerminatorCodegenHelper

pub(in mir::block) struct TerminatorCodegenHelper<'tcx> {
    bb: BasicBlock,
    terminator: &'tcx Terminator<'tcx>,
    funclet_bb: Option<BasicBlock>,
}

Used by FunctionCx::codegen_terminator for emitting common patterns e.g., creating a basic block, calling a function, etc.

Fields

bb: BasicBlock

terminator: &'tcx Terminator<'tcx>

funclet_bb: Option<BasicBlock>

Implementations

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

pub(in mir::block) fn funclet<'b, Bx: BuilderMethods<'a, 'tcx>>(
    &self,
    fx: &'b mut FunctionCx<'a, 'tcx, Bx>
) -> Option<&'b Bx::Funclet>

Returns the associated funclet from FunctionCx::funclets for the funclet_bb member if it is not None.

pub(in mir::block) fn lltarget<Bx: BuilderMethods<'a, 'tcx>>(
    &self,
    fx: &mut FunctionCx<'a, 'tcx, Bx>,
    target: BasicBlock
) -> (Bx::BasicBlock, bool)

pub(in mir::block) fn llblock<Bx: BuilderMethods<'a, 'tcx>>(
    &self,
    fx: &mut FunctionCx<'a, 'tcx, Bx>,
    target: BasicBlock
) -> Bx::BasicBlock

Create a basic block.

pub(in mir::block) fn funclet_br<Bx: BuilderMethods<'a, 'tcx>>(
    &self,
    fx: &mut FunctionCx<'a, 'tcx, Bx>,
    bx: &mut Bx,
    target: BasicBlock
)

pub(in mir::block) fn do_call<Bx: BuilderMethods<'a, 'tcx>>(
    &self,
    fx: &mut FunctionCx<'a, 'tcx, Bx>,
    bx: &mut Bx,
    fn_abi: FnAbi<'tcx, Ty<'tcx>>,
    fn_ptr: Bx::Value,
    llargs: &[Bx::Value],
    destination: Option<(ReturnDest<'tcx, Bx::Value>, BasicBlock)>,
    cleanup: Option<BasicBlock>
)

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

pub(in mir::block) fn maybe_sideeffect<Bx: BuilderMethods<'a, 'tcx>>(
    &self,
    mir: &'tcx Body<'tcx>,
    bx: &mut Bx,
    targets: &[BasicBlock]
)
