This CL extends BoundedPageAllocator with PageFreeingMode parameter which controls how pages should be freed: by setting permissions to kNoAccess (preferred) or by discarding pages (Apple Silicon specific behavior for RWX pages). The latter mode allows to ensure that once pages are configured with RWX permissions they are never reconfigured to anything else again. The new mode will be used in a follow-up CL.

Young GlobalHandle nodes were processed during post processing which required a logic to defend against recursive GCs. This was originally designed in a delayed way as the list itself was only treated as an optimization and could thus be lazily cleared. Since this still happens in the atomic pause and every node needs to be visited, there's no advantage over just keeping it correct at all times.

Make sure that Call nodes are only added to the graph after their arguments are processed. Previously we were already doing this for the undefined constant, but forgot to also do it for tagging nodes. Now rather than trying to add those nodes before creating the Call node, we create the Call node without adding it to the graph, then add it only after setting up its inputs.

Invoking a JSBoundFunction is slightly slower than a normal JSFunction (since we don't have to first jump to the target_function). The closure steps in SourceTextModule ExecuteAsyncModule is controlled by the engine so it is better to create dedicated context slots for the captured values.

Once we start protecting assembler buffers via PKU, the background compile threads need to enable write permissions during compilation in order to access them. This CL adds that, with a little trick to allow passing {nullptr} to the {CodeSpaceWriteScope} for configurations where we do not actually use the provided {NativeModule}. This is needed because the background compile threads do not keep the {NativeModule} alive during compilation, so they also should not pass the potentially dangling pointer to the {CodeSpaceWriteScope}.

This CL switches over our OSR system to be based on the feedback vector osr caches. - OSRing to Sparkplug is fully separated from OSR urgency. If SP code exists, we simply jump to it, no need to maintain an installation request. - Each JumpLoop checks its dedicated FeedbackVector cache slot. If a valid target code object exists, we enter it *without* calling into runtime to fetch the code object. - Finally, OSR urgency still remains as the heuristic for requesting Turbofan OSR compile jobs. Note it no longer has a double purpose of being a generic untargeted installation request. With the new system in place, we can remove now-unnecessary hacks: - Early OSR tierup is replaced by the standard OSR system. Any present OSR code is automatically entered. - The synchronous OSR compilation fallback is removed. With precise installation (= per-JumpLoop-bytecode) we no longer have the problem of 'getting unlucky' with JumpLoop/cache entry mismatches. Execution has moved on while compiling? Simply spawn a new concurrent compile job. - Remove the synchronous (non-OSR) Turbofan compile request now that we always enter available OSR code as early as possible. - Tiering into Sparkplug no longer messes with OSR state.

This introduces an AssemblerBufferCache class which will (later) cache the backing store of AssemblerBuffers. This is needed for PKU-protected assembler buffers, which are expensive to allocate and deallocate. For now, the AssemblerBufferCache does not do any caching, this will be added in a follow-up CL.

This is a reland of commit 62632c08. Reason for previous revert: Performance regressions crbug.com/1315724. The reland only optimizes strict equal boolean literal like "a===true" or "a===false", and we generate TestReferenceEqual rather than TestStrictEqual for the comparasion. And also add typed optimization for ReferenceEqual when all inputs are boolean with boolean constant. Original change's description: > [interpreter] Optimize strict equal boolean > > For strict equal boolean literal like "a===true" > or "a===false", we could generate TestReferenceEqual > rather than TestStrictEqual.

For call_direct, feedback (for the first level of inlining) only records call counts, not the statically-known target. So to be able to make feedback for potential additional inlining levels available, the feedback processor must look to the wire bytes to extract the call targets. Without feedback and hence unknown call counts, such multi-level inlining would not happen.

These were originally proposed as a part of the fixed-width SIMD proposal, and were then migrated to the relaxed-simd proposal which also deems these operations out of scope.

One of the biggest categories in heap snapshots is named “(system)”, which gives developers no indication of why all that memory is used or what they might do to reduce it. In this change, I propose that we create a new category for Maps, DescriptorArrays, and related objects, and call this new category “(object shape)” in the devtools. I think that this category name would be more meaningful, while still grouping those objects together so that they mostly stay out of the way.
