Fixed conflict with drop elaboration and coverage See https://github.com/rust-lang/rust/issues/80045#issuecomment-745733339 Coverage statements are moved to the beginning of the BCB. This does also affect what's counted before a panic, changing some results, but I think these results may even be preferred? In any case, there are no guarantees about what's counted when a panic occurs (by design).

Combination of commits Fixes multiple issue with counters, with simplification Includes a change to the implicit else span in ast_lowering, so coverage of the implicit else no longer spans the `then` block. Adds coverage for unused closures and async function bodies. Fixes: #78542 Adding unreachable regions for known MIR missing from coverage map Cleaned up PR commits, and removed link-dead-code requirement and tests Coverage no longer depends on Issue #76038 (`-C link-dead-code` is no longer needed or enforced, so MSVC can use the same tests as Linux and MacOS now) Restrict adding unreachable regions to covered files Improved the code that adds coverage for uncalled functions (with MIR but not-codegenned) to avoid generating coverage in files not already included in the files with covered functions. Resolved last known issue requiring --emit llvm-ir workaround Fixed bugs in how unreachable code spans were added.
