The file is now using CPURegister without declaring it. This may or may not just compile because of unified builds, but it broke at least one build: https://build.webkit.org/#/builders/133/builds/4298/steps/9/logs/stdio
Created attachment 445547 [details] v1 Add include for CPURegister.
Created attachment 445548 [details] v2 Now with the right include!
Committed r286360 (244719@main): <https://commits.webkit.org/244719@main> All reviewed patches have been landed. Closing bug and clearing flags on attachment 445548 [details].
