Can I remove one LLVM ?
I have llvm 18 and 19.
I have been using stable Gentoo.

| Try it and see. What is the output of emerge --ask --verbose --depclean sys-devel/llvm? |

No. Mesa specifically needs 18, at least for now:

If emerge --depclean does not want to clean it, something holds on to it. GDH-Gentoo has already given you the answer to what it is.
You don't need to remove it, it won't do much for you. It won't even free significant amount of space and it doesn't run by itself, so you don't have a good reason to want to remove it until emerge --depclean decides so.
Best Regards,
Georgi |

But then you may be recompiling the version you do not use if it is updated, and clang with llvm is a non-trivial compilation. Recent introduction of 19 and update of 18 took my laptop few hours to deal with. |

Also qttools it seems. Actually nothing needs 19 version |

| media-libs/mesa (and intel_clc) works find with LLVM_SLOT=19. It's just the ebuids that are missing an update. |

If you're sure about that, file a bug.

I should have been more careful with my wording, but in my defense, it was almost 03:00 and I should have been asleep.
I've ran the tests with LLVM_SLOT=19 set on libclc, intel_clc and mesa. All tests pass, but I only have VIDEO_CARDS=intel, so I don't know if my testing is enough for the bug report.
I've been running with only llvm:19 on my system for a few months now. |

Look at the stabilization bugs. Your input might still be useful.

| As I understand it, Mesa is already using LLVM 18, so there is nothing to force. There was discussion here of whether LLVM 19 would be viable for Mesa. |

Yes, sorry.
Force rebuild with llvm 19 and remove llvm 18.
Or rebuild whole world with 18 and remove 19 ? |

Unless you want to create a maintenance problem, leave both versions alone.
LLVM 18 is needed for Mesa. Some of its components link to this version's libraries, so you can't get rid of it for now.
And you'll have LLVM 19 because you are on an LLVM profile, 19 is the latest stable, and Gentoo is rolling release.
