I updated to sys-devel/clang-9.0.0 and unmerged sys-devel/clang-8.0.1 afterwards.  Then I tried to update from dev-util/lldb-8.0.1 to dev-util/lldb-9.0.0.  This failed with:

You probably forgot to rebuild packages depending on sys-devel/clang:= (app-doc/doxygen[clang] is one of them).
Check:

$ (cd /var/db/pkg; grep -E "sys-devel/clang-[^[:space:]]*:[0-8]/[^[:space:]]+=" */*/RDEPEND)

In any case, libraries of packages that are being uninstalled should be preserved, if other packages are still using them, not?

[Comment 4 Michał Górny 2019-09-28 06:31:00 UTC]

Did you use -C or --depclean?

emerge -C llvm:8

Then you have no reason to complain that it broke your packages.

Though I suppose doxygen should have been rebuilt when clang was upgraded.  I guess it's only brought in via build-time dependencies, and that's why Portage didn't bother.  Nevertheless, that's going to prevent people from unmerging old slots forever.

Reassigning to Portage people.

Libraries used by other packages, like dev-qt/qt-creator or dev-qt/qdoc, were preserved by `emerge -C llvm:8`, which is why I expected the same to happen for app-doc/doxygen and media-libs/mesa (bug #695646) as well.
