> This REDO PR has ~two~ 3 commits. > > The first commit is a straight re-application of the original > [JDK-8371643](https://bugs.openjdk.org/browse/JDK-8371643) change that > removes `ThreadLocalAllocBuffer::_reserve_for_allocation_prefetch` and > related code. > > That original change was backed out after it surfaced two pre-existing > issues: a real bug on master > ([JDK-8373021](https://bugs.openjdk.org/browse/JDK-8373021), now fixed), and > an intermittent test bug in `compiler/unsafe/AlignmentGapAccess.java` > ([JDK-8373487](https://bugs.openjdk.org/browse/JDK-8373487)). > > The second commit temporarily adds `compiler/unsafe/AlignmentGapAccess.java` > to the ProblemList. The reason is that this TLAB cleanup makes that > intermittent failure happen much more frequently. > > Of course we can wait until that test bug is fixed, but I think it is better > to merge this sooner and keep that test in the ProblemList for now. That lets > us keep incubating this cleanup in CI while also giving us a better chance to > uncover other existing issues. > > The third commit adds a new test that exercises large `AllocatePrefetch*` > flags values. > Test: tier1-3
