With this Cl, a function that has been marked for deoptimization will not be reported as optimized. This protects against potential races where an mjsunit tests assertUnoptimized, and the optimized code for the function has been marked for deoptimization, but not been disposed of yet. The potential for this race has been discovered in the context of bug v8:9563, but this CL is not a fix for that bug.

This reverts commit dc1cc223. Revert "[regexp] Implement the match indices proposal" This reverts commit 9460101c. Reason for revert: Causes confusion on Blink side, as it introduces an object with >=2 internal fields that is not a wrapper (see bug).

In order to reflect web reality, TC39 has made some slight changes to name descriptors, see https://github.com/tc39/ecma262/pull/1490 for details. V8 was mostly already in compliance with these changes, but ThrowTypeError and anonymous classes needed some slight changes.

Replace uses of WordEqual on two tagged representation nodes with a new TaggedEqual helper, which on pointer compressed configs only compares the bottom 32-bits of the word. We no longer allow using WordEqual on anything not known to be a WordT (i.e. Node* or TNode<Object>). In the future, this may allow us to ignore the top bits of an uncompressed Smi, and have simpler decompression, though this patch is not sufficient for such a change. As a necessary drive-by, TNodify a bunch of stuff.

This changes Compiler::CollectSourcePositions to skip finalization of the BytecodeArray, constant table, handler table, ScopeInfos as well as internalization of Ast values since only the source position table is used and the others will be collected soon after by the GC. It will also now avoid recompiling inner functions that would otherwise be eagerly compiled. BytecodeArrayWriter::ToBytecodeArray has been changed to never populate the source_position_table.

Avoid clearing the memory on the embedder-side of a TracedGlobal handle. When using destructors in TracedGlobal this is safe as long as the embedder reports the handle on tracing GCs. If the embedder does not report a handle it is assumed that the containing object is dead as well. Without using destructors the same argument holds for tracing GCs. In addition, embedders using the optimization of clearing references on non-tracing GCs are expected to clear the reference in ResetHandleInNonTracingGC. It is suggested that only expert embedders make use of (a) no destructors and (b) IsRootForNonTracingGC.

This change adds the indexed field for the characters in the definition of sequential string types, and introduces support for recognizing the various specific string types in v8_debug_helper. In an attempt to avoid duplicating info about string instance types, it also refactors String::Get so that StringShape (a simple class usable by postmortem tools) can dispatch using a class that defines behaviors for each concrete type.

This new FreeList should be a reasonable replacement for our old FreeListLegacy: it is slightly less efficient (~1%), but uses much less memory (often 5% less old_space size). It is based on FreeListMany, with the following additions: - A cache to waste less time iterating empty categories - A fast path for allocations done in the runtime and generated code - A slow path (the same as FreeListMany actually) for allocations done in the GC.

For import wrappers, we add a special "callable" parameter as the last parameter. This parameter is not set in the TurboFan graph but in the code generator. Therefore this parameter has to be allocated in a special register and cannot be lowered generically. With this CL we detect in the CallDescriptor lowering if the last parameter is this special "callable" parameter. If so, we preserve it in the lowered CallDescriptor in the same register.

This CL adds a mechanism that prevents the RuntimeProfiler from triggering optimization of a function after %PrepareFunctionForOptimization has been called. This is useful to prevent flakiness in tests, as sometimes a function that already got deoptimized would receive a new code object from a concurrent compile that was triggered by a heuristic just in the right moment for the assertUnoptimized test to fail. For example, the following was happening: PrepareFunctionForOptimization [marking `testAdd` for optimized recompilation, reason: small function] [concurrently compiling method `testAdd` using TurboFan] [manually marking `testAdd` for non-concurrent optimization] [synchonously compiling method `testAdd` using TurboFan] [synchonously optimizing `testAdd` produced code object 0xAAAA - took 1.638 ms] Runtime_GetOptimizationStatus OPTIMIZED `testAdd` (code object 0xAAAA) DeoptimizeFunction `testAdd` with Code Object 0xAAAA [concurrently optimizing `testAdd` produced code object 0xBBBB - took 3.377 ms] Runtime_GetOptimizationStatus OPTIMIZED `testAdd` (code object 0xBBBB) Bug: v8:9563 Change-Id: Ia4c846aba95281589317d43b82383e70fe0a35f5 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1763546Reviewed-by:

This reverts commit aba185a7. Reason for revert: We want to keep this API.
