.. when deoptimization occurs after the outermost loop containing the loop that triggered OSR compilation. The reasoning is that the main benefit of OSR'd code is speeding up the OSR'd loop; the speedup of the OSR'd loop is assumed to be higher than deoptimization overhead. This is a slightly modified version of crrev.com/c/3521361, credit goes to tao.pan@intel.com for most of the investigation and implementation work.

Table.set has two arguments, the table index and the value. Therefore Table.set was defined with a length of 2. However, the value argument is optional, so the length should actually be 1.

When updating pointers during a full GC, a page might not be swept already. In such cases there might be invalid objects and slots recorded in free memory. Updating tagged slots in free memory is fine even though it is superfluous work. However, the GC also needs to calculate the size of potentially dead invalid objects in order to be able to check whether a slot is within that object. But since that object is dead, its map might be dead as well which makes size calculation impossible on such objects. The CL changes this to cache the size of invalid objects. A follow-up CL will also check the marking bit of invalid objects.

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}.

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.

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?

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.

We need to use MachineRepresentation to properly distinguish the types in compiler::UnallocatedOperand. Bug: v8:7700 Change-Id: I4273512a00290bb85b09aeb3788643e346be03f7 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3602515Reviewed-by:

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.
