This is a reland of 44708a5b Original change's description: > [compiler, heap] Create LocalHeap outside of ExecuteJob > > Create LocalHeap directly in the Task or in GetOptimizedCodeNow and > pass its reference as argument to ExecuteJob. This allows us to create > LocalHeap differently for the main and background thread, e.g. by > passing an additional argument to the constructor in the future. > It will be required in the future anyways when the main thread will > have its own LocalHeap/LocalIsolate. > > Extending the scope of LocalHeap, also made > HandleBase::IsDereferenceAllowed more precise and uncovered two > potential issues: heap accesses in > OptimizingCompileDispatcher::CompileNext and PipelineImpl::AssembleCode > with --code-comments. > > LocalHeap can now be created in the parked state. Also fixed a data > race with LocalHeap's destructor publishing write barrier entries > without holding the lock. > > Bug: v8:10315 > Change-Id: I9226972601a07b87108cd66efbbb6a0d118af58d > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2460818 > Commit-Queue: Georg Neis <neis@chromium.org> > Reviewed-by: Leszek Swirski <leszeks@chromium.org> > Reviewed-by: Santiago Aboy Solanes <solanes@chromium.org> > Reviewed-by: Georg Neis <neis@chromium.org> > Reviewed-by: Ulan Degenbaev <ulan@chromium.org> > Cr-Commit-Position: refs/heads/master@{#70521} Bug: v8:10315 Change-Id: I4c459fd6dfb98d47fc9941c0dc6864bf5a1d2d3e Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2474788Reviewed-by: Ulan Degenbaev <ulan@chromium.org> Reviewed-by: Santiago Aboy Solanes <solanes@chromium.org> Reviewed-by: Georg Neis <neis@chromium.org> Reviewed-by: Leszek Swirski <leszeks@chromium.org> Commit-Queue: Dominik Inführ <dinfuehr@chromium.org> Cr-Commit-Position: refs/heads/master@{#70560}
