Adds feature-gated `#[no_coverage]` function attribute, to fix derived Eq `0` coverage issue #83601 Derived Eq no longer shows uncovered The Eq trait has a special hidden function. MIR `InstrumentCoverage` would add this function to the coverage map, but it is never called, so the `Eq` trait would always appear uncovered. Fixes: #83601 The fix required creating a new function attribute `no_coverage` to mark functions that should be ignored by `InstrumentCoverage` and the coverage `mapgen` (during codegen). Adding a `no_coverage` feature gate with tracking issue #84605. r? `@tmandry` cc: `@wesleywiser` |
