For example, https://codecov.io/gh/dlang/dmd/src/master/src/dmd/backend/cod4.d shows 0% coverage.

Probably because the backend is compiled with `-betterC` which apparently breaks `-cov`.

@MoonlightSentinel created dlang/dmd pull request #11522 "Workaround for Issue 21119 - Disable -betterC for coverage builds" mentioning this issue: - Workaround for Issue 21119 - Disable -betterC for coverage builds because -betterC apparently breaks coverage generation https://github.com/dlang/dmd/pull/11522

-cov requires linking with druntime, and -betterC explicitly must not require druntime. This is not a bug in the backend.

Working now.
