-# FIXME(richkadel): I'm adding `--ignore-filename-regex=` line(s) for specific test(s) that produce
-# `llvm-cov` results for multiple files (for example `uses_crate.rs` and `used_crate/mod.rs`) as a
-# workaround for two problems causing tests to fail on Windows:
-#
-# 1. When multiple files appear in the `llvm-cov show` results, each file's coverage results can
-# appear in different a different order. Whether this is random or, somehow, platform-specific,
-# the Windows output flips the order of the files, compared to Linux. In the `uses_crate.rs`
-# test, the only test-unique (interesting) results we care about are the results for only one
-# of the two files, `mod/uses_crate.rs`, so the workaround is to ignore all but this one file.
-# In the future, we may want a more sophisticated solution that splits apart `llvm-cov show`
-# results into separate results files for each result (taking care not to create new file
-# paths that might be too long for Windows MAX_PATH limits when creating these new sub-results,
-# as well).
-# 2. When multiple files appear in the `llvm-cov show` results, the results for each file are
-# prefixed with their filename, including platform-specific path separators (`\` for Windows,
-# and `/` everywhere else). This could be filtered or normalized of course, but by ignoring
-# coverage results for all but one of the file, the filenames are no longer included anyway.
-# If this changes (if/when we decide to support `llvm-cov show` results for multiple files),
-# the file path separator differences may need to be addressed.
-#
-# Since this is only a workaround, I decided to implement the override by adding an option for
-# each file to be ignored, using a `--ignore-filename-regex=` entry for each one, rather than
-# implement some more sophisticated solution with a new custom test directive in the test file
-# itself (similar to `expect-exit-status`) because that would add a lot of complexity and still
-# be a workaround, with the same result, with no benefit.
-#
-# Yes these `--ignore-filename-regex=` options are included in all invocations of `llvm-cov show`
-# for now, but it is effectively ignored for all tests that don't include this file anyway.
-#
-# (Note that it's also possible the `_counters.<test>.txt` and `<test>.json` files (if generated)
-# may order results from multiple files inconsistently, which might also have to be accommodated
-# if and when we allow `llvm-cov` to produce results for multiple files. Note, the path separators
-# appear to be normalized to `/` in those files, thankfully.)

- 66| |// | Unexecuted instantiation: used_crate::used_only_from_bin_crate_generic_function::<_>
- 67| |//
- 68| |// These notices appear when `llvm-cov` shows instantiations. This may be a
- 69| |// default option, but it can be suppressed with:
- 70| |//
- 71| |// ```shell
- 72| |// $ `llvm-cov show --show-instantiations=0 ...`
- 73| |// ```
- 74| |//
- 75| |// The notice is triggered because the function is unused by the library itself,
- 76| |// and when the library is compiled, a synthetic function is generated, so
- 77| |// unused function coverage can be reported. Coverage can be skipped for unused
- 78| |// generic functions with:
- 79| |//
- 80| |// ```shell
- 81| |// $ `rustc -Zunstable-options -C instrument-coverage=except-unused-generics ...`
- 82| |// ```
- 83| |//
- 84| |// Even though this function is used by `uses_crate.rs` (and
- 85| |// counted), with substitutions for `T`, those instantiations are only generated
- 86| |// when the generic function is actually used (from the binary, not from this
- 87| |// library crate). So the test result shows coverage for all instantiated
- 88| |// versions and their generic type substitutions, plus the `Unexecuted
- 89| |// instantiation` message for the non-substituted version. This is valid, but
- 90| |// unfortunately a little confusing.
- 91| |//
- 92| |// The library crate has its own coverage map, and the only way to show unused
- 93| |// coverage of a generic function is to include the generic function in the
- 94| |// coverage map, marked as an "unused function". If the library were used by
- 95| |// another binary that never used this generic function, then it would be valid
- 96| |// to show the unused generic, with unknown substitution (`_`).
- 97| |//
- 98| |// The alternative is to exclude all generics from being included in the "unused
- 99| |// functions" list, which would then omit coverage results for
- 100| |// `unused_generic_function<T>()`, below.
