Struct rustc_mir_transform::remove_noop_landing_pads::RemoveNoopLandingPads

pub struct RemoveNoopLandingPads;

A pass that removes noop landing pads and replaces jumps to them with None. This is important because otherwise LLVM generates terrible code for these.

Implementations

impl RemoveNoopLandingPads

fn is_nop_landing_pad(
    &self,
    bb: BasicBlock,
    body: &Body<'_>,
    nop_landing_pads: &BitSet<BasicBlock>
) -> bool

fn remove_nop_landing_pads(&self, body: &mut Body<'_>)

Trait Implementations

impl<'tcx> MirPass<'tcx> for RemoveNoopLandingPads

fn is_enabled(&self, sess: &Session) -> bool

Returns true if this pass is enabled with the current combination of compiler flags.

fn run_pass(&self, _tcx: TyCtxt<'tcx>, body: &mut Body<'tcx>)

fn name(&self) -> Cow<'_, str>

fn phase_change(&self) -> Option<MirPhase>

If this pass causes the MIR to enter a new phase, return that phase.

fn is_mir_dump_enabled(&self) -> bool
