- `llvm-cov-flags` adds extra flags when running LLVM's `llvm-cov` tool.
- Used by [coverage tests](compiletest.md#coverage-tests) in `coverage-run` mode.
### Tidy specific directives
The following directives control how the [tidy script](../conventions.md#formatting)
verifies tests.
- `ignore-tidy-target-specific-tests` disables checking that the appropriate
LLVM component is required (via a `needs-llvm-components` directive) when a
test is compiled for a specific target (via the `--target` flag in a
`compile-flag` directive).
- [`unused-revision-names`](compiletest.md#ignoring-unused-revision-names) -
suppress tidy checks for mentioning unknown revision names.
