8256740: ZGC: Move closures out of zOopClosure files #1347

wants to merge 1 commit into from


Copy link

@stefank stefank commented Nov 20, 2020

zOopClosures.hpp and zOopClosures.inline.hpp contain a collection of different closures. There used to be a need to split closures and have them registered with the oop iterate framework, but that has been fixed with the last oop iterate framework rewrite.

I propose that we move the closures out to the sub-systems where they are used.
