Generate coverage reports of source code evaluated by miri?

[anp]

I'm setting up CI with coverage and miri for the first time in a while and thought it would be nice to measure how much of the non-#[cfg(miri)] code is covered when run under miri.

I see several previous discussions in this repository about measuring the coverage of miri itself, but I can't find any previous discussions or documentation about generating coverage reports for the code under test. Is that already possible, and if not is it something that has been discussed previously?

No, this is not currently possible. I think we have an issue in the rustc repo for coverage during const-eval, but not one for Miri.
