coverage: Shrink call spans to just the function name

2025-04-01T02:07:33+00:00

This is a way to shrink call spans that doesn't involve mixing different spans, and avoids overlap with argument spans. This patch also removes some low-value comments that were causing rustfmt to ignore the match arms.

coverage: Separate span-extraction from unexpansion

coverage: Defer part of counter-creation until codegen

coverage: Rename `basic_coverage_blocks` to just `graph`

2024-12-20T06:48:59+00:00

During coverage instrumentation, this variable always holds the coverage graph, which is a simplified view of the MIR control-flow graph. The new name is clearer in context, and also shorter.

coverage: Treat await similar to a macro

2024-09-06T05:01:59+00:00

Currently `await` is only counted towards coverage if the containing function is suspended and resumed at least once. This is because it expands to code which contains a branch on the discriminant of `Poll`. By treating it like a branching macro (e.g. `assert!`), these implementation details will be hidden from the coverage results.

coverage: Extract hole spans from HIR instead of MIR

2024-07-08T11:22:56+00:00

This makes it possible to treat more kinds of nested item/code as holes, instead of being restricted to closures.
