2021-04-02	Simplify coverage tests	Rich Kadel	-75/+0
	This change reduces the risk of impacting coverage tests on unrelated changes (such as MIR and Span changes), and reduces the burden when blessing coverage changes in case it is necessary. * Remove all spanview tests. The spanview tests were useful during development, but they can be generated as needed, via compiler command line flags. They aren't critical to confirming coverage results. (The coverage report tests are sufficient.) When spanview regeneration was necessary, the diffs were way too hard to read to be useful anyway. So I'm removing them to reduce friction from a feature that is no longer useful. * Remove the requirement for `llvm-cov show --debug` when blessing tests. The `--debug` flag is, unfortunately, only available if LLVM is built with `optimize = false` (in Rust's config.toml). This adds significant time and resource burdens to the contributor's build. As it turns out, for other reasons in the past, I wasn't actually using the debug output (counter info) to validate coverage anymore either, so it was required for no reason, I now realize.
2020-12-03	Combination of commits	Rich Kadel	-0/+75
	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.
