JDK-8135018 - AARCH64: Missing memory barriers for CMS collector
Description
The dirty marking of the card table needs to be a releasing store for CMS. It's already there in template interpreter and C2 on PPC64. We have seen GC crashed when testing C1 on PPC64.
This change is a prerequisite for our C1 on PPC64 contribution.
Comments
It is already fixed in hs-rt: 8135018: AARCH64: Missing memory barriers for CMS collector We just have to wait until it gets merged into hs-comp.
