[PATCH] D156491: [RA] Split a virtual register in cold blocks if it is not assigned preferred physical register

[Hans Wennborg via Phabricator via llvm-commits]

hans added a comment.

We're seeing binary size increases in Chromium, in particular for Android and Fuchsia where size is critical: https://crbug.com/1488374
Is that an inherent property of this change, and could it be scaled back for optsize functions for example?
