This method used to be defined on Object and handled Strings and JSObjects; but only the object hierarchy rooted at JSObject has 'elements', and Strings are handled slightly differently. Thus it makes sense to split up into JSObject::GetOwnConstantElement String::GetCharAsString This way, we can also separate future work on making JSObjects and Strings never-serialized.

Currently if gn check is enabled (with v8/third_party ignored), there are many errors due to headers being used without adding the proper dependency in BUILD.gn (or because it's being used transitively without a public_deps chain). This makes the number of errors go from 2114 to 195. Apart from adding dependencies, it also moves _v8_internal_Node_Print from objects-printer.cc to node.cc so it can see the Node::Print method which wouldn't otherwise be possible without a circular dependency. Also removes the previously deleted compiler/graph-builder-tester.h file.

Earlier we used the same interrupt budget always and waited for higher number of ticks when tiering up from Turboprop to TurboFan. On some of the real world pages this adds a reasonable overhead for processing these interrupts. This cl sets the interrupt budget to a higher value so there are fewer interrupts. This cl: 1. Sets the interrupt budget on feedback cell to FLAG_interrupt_budget * scale factor when we install optimized code. 2. Resets the budget to FLAG_interrupt_budget when there is a deoptimization. 3. Updates the runtime profiler to remove the scaling of number of ticks needed for optimization when tiering up from TP to TF. On sheets benchmark, we spend 40-50ms when servicing interrupts from Turboprop code. This change brings it down to ~7ms. We also see improvements on other pages.

This CL introduces a test runner flag to detect if webassembly has been disabled. Since all tests that require wasm are alrady skipped in lite mode, we introduce a has_webassembly flag for the test runner which checks for v8_enable_webassembly=true and v8_enable_lite_mode=false. As a drive-by, we also do not set the V8_ENABLE_WEBASSEMBLY preprocessor flag if lite mode is enabled. The status files are updated by splitting wasm tests from the "lite_mode" section and checking for "not has_webassembly" instead. Note that the v8_enable_webassembly=false configuration is not tested on any bot currently, but I will make sure that all tests keep passing on further changes in this configuration.

Whenever we destroy an object that contains a (Weak)(CrossThread)Persistent, we call the Persistent's dtor which frees the relevant PersistentNode. To get the PersistentRegion for the node, we get the value, then get the the relevant page which holds a reference to the heap which holds the regions. During a termination GC there is no marking and no weak callback processing. That means that, when destroying a Persistent, the page on which the object referenced by the Persistent resides may have already been swept and destroyed. Then when we try to get the page we cleared or unallocated memory and crash. This issue presented as a sweeper crash in the web tests and content_browsertests. This issue affects only Weak(CrossThread)Persistent since the region for their strong counterparts are already cleared at the start of a termination GC. This is not an issue in the Blink impl because (1) Blink finds the elevant regions through ThreadState without going through pages, and (2) Blink runs a full GC on termination that includes executing weak callbacks. Alternatively we could trace the Weak(CrossThread)Persistent region which will run the weakness callbacks and clear all WeakPersistents. The cost and outcome is equivalent.

On 64-bit platforms we reserve the maximum size of a WebAssembly memory. Thereby the memory can grow in-place. On 32-bit platforms, however, we allocate only the initial size, and grow the memory by reallocating the memory. Due to memory fragmentation the memory therefore cannot grow big. With this CL we allow to reserve 1GB of memory even on 32-bit platforms. Thereby the memory can grow to at least 1GB.

This reverts commit ed225df7. Reason for revert: Blocks the roll, causing compile failures in Chromium: https://ci.chromium.org/p/chromium/builders/try/win_chromium_compile_dbg_ng/800868? Original change's description: > [objects] Cache the ExternalString's data in its resource > > For external uncached strings (also called "Small External Strings") > with cacheable resources, we can cache its resource's data at the > string's creation time. This allows us to safely read the data from the > background as we wouldn't trigger a data() callback. > > For more information regarding the investigation and possible proposals > see > https://docs.google.com/document/d/101eAQqFpBPWFGNJicxtdlwYShJkTOUsEuxkVVeu5Hrk/edit?usp=sharing > > Bug: v8:7790, v8:11463 > Change-Id: I6164092b01a6ccb525a9516f476e066b35fb1f96 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2685177 > Commit-Queue: Santiago Aboy Solanes <solanes@chromium.org> > Reviewed-by: Ulan Degenbaev <ulan@chromium.org> > Reviewed-by: Leszek Swirski <leszeks@chromium.org> > Cr-Commit-Position: refs/heads/master@{#72862} Bug: v8:7790 Bug: v8:11463 Change-Id: I1d14c2f9872d156d43d5d95c8a032a37ba9379cb No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2708824 Auto-Submit: Bill Budge <bbudge@chromium.org> Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Commit-Queue: Bill Budge <bbudge@chromium.org> Reviewed-by:

Use a slightly different instruction sequence for AVX, these instructions issue to different ports, resulting in less resource pressure. Full details in the bug.
