Installation of mesa-git from AUR

I am wondering if I can safely install it via yay -S mesa-git and simply replace mesa when prompted.

I am confused about the pinned comment because I am not entirely sure what it means exactly, and when will I have to perform (if at all) those extra steps (AUR package):

Mesa and llvm are closely tied together. Everytime the llvm mesa is built against changes/updates , mesa needs to be rebuilt.

I expect anyone building mesa-git against one of the llvm trunk variants to be able to do that themselves, but atleast some of the people that built against repo llvm don't understand how to deal with such a rebuild.

The rest of this post is meant for those people.

* Verify if latest PKGBUILD requirements match llvm repo versions.
* If they don't , post to alert me of this.
* DELAY the update of llvm/clang suite and their lib32- counterparts
* Once the PKGBUILD does match, download it.

`Option A - best one`

* run pacman -Syu to ensure your system is in sync with your mirrror server
* build mesa-git in a clean chroot

see for the official way or for an alternative method.

* install the newly built mesa-git
* run pacman -Syu
* ready

`Option B - 2nd best`

* revert to repo mesa
* pacman -Syu
* build mesa-git
* switch from mesa to mesa-git
* ready

Do I also then need to install lib32-mesa-git?
