Variants

Initial

PromoteConsts

RemoveFalseEdges

PostAnalysis

Runs at the beginning of “analysis to runtime” lowering, before drop elaboration.

PreOptimizations

Runs at the end of “analysis to runtime” lowering, after drop elaboration. This is before the main optimization passes on runtime MIR kick in.

Final

MakeShim

AfterUnreachableEnumBranching

Implementations

impl SimplifyCfg

fn name(&self) -> &'static str

Trait Implementations

impl<'tcx> MirPass<'tcx> for SimplifyCfg

fn name(&self) -> &'static str

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

fn is_required(&self) -> bool

Returns true if this pass must be run (i.e. it is required for soundness). For passes which are strictly optimizations, this should return false. If this is false, #[optimize(none)] will disable the pass.

fn profiler_name(&self) -> &'static str

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

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

fn can_be_overridden(&self) -> bool

Returns true if this pass can be overridden by -Zenable-mir-passes. This should be true for basically every pass other than those that are necessary for correctness.

fn is_mir_dump_enabled(&self) -> bool

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
