Ordering issue example

When upgrading llvm along with other things, I missed lldb from outside @world upgrade run, but the output was very verbose and hard to spot the issue.
It outputs issues between clang and llvm 19 times (where each takes several lines on a terminal) and the real issue is somewhere in the middle, buried in the spam.
The spam happens due to all the different LLVM_TARGETS constraints that portage decides to list one by one instead of at once, which is a separate thing I understand is already on the radar or something separately.

Sam thinks there are improvements possible here in terms of the ordering of this output that you can see attached.
Comment 1 Zac Medico gentoo-dev 2023-11-01 16:25:21 UTC
The clang deps do specify each target separately like this:

  llvm_targets_AArch64? ( ~sys-devel/llvm-17.0.3[llvm_targets_AArch64] )

Portage could group them by parent, and could possibly even merge multiple targets into a single atom, though merged atoms could be a little confusing since they differ from what the ebuild specified.
Comment 2 Mart Raudsepp gentoo-dev 2023-11-01 20:56:26 UTC
So separately, maybe llvm.org.eclass could build the dep atom a bit differently.
