[PATCH] D98232: [regalloc] Ensure Query::collectInterferringVregs is called before interval iteration

[Mircea Trofin via Phabricator via llvm-commits]

mtrofin added a comment.

Resurrecting the topic here: @nikic @lebedev.ri @dmgreen @qcolombet @aditya_nandakumar

should we go ahead and revert (most of*) https://reviews.llvm.org/D35816? IIRC, @aditya_nandakumar and @qcolombet 's work would make the eviction chains introduced in https://reviews.llvm.org/D35816 unnecessary. We disabled it, too, with the change here, and haven't heard any complaints.

*The reason I'm saying "most of" is because https://reviews.llvm.org/D35816 had some changes to weight calculation, too. So I'd prefer keeping that. The rest would go (code in regalloc and tests)
