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. 2020-12-01 01:58:08 -06:00			`1\| 1\|fn main() {`

Reland - Report coverage `0` of dead blocks Fixes: #84018 With `-Z instrument-coverage`, coverage reporting of dead blocks (for example, blocks dropped because a conditional branch is dropped, based on const evaluation) is now supported. Note, this PR relands an earlier, reverted PR that failed when compiling generators. The prior issues with generators has been resolved and a new test was added to prevent future regressions. Check out the resulting changes to test coverage of dead blocks in the test coverage reports in this PR. 2021-05-01 16:56:48 -05:00			`3\| 0\| loop {}`
