This includes WasmEngine::NewNativeModule() and WasmModuleObject::New(). The intent is to make the various ways of creating a module (sync, async, deserialize, import) more similar. After this change, a NativeModule will always be created before a WasmModuleObject. This will make it easier to look up a cached NativeModule given its wire bytes. The following changes are made: * Use WasmCodeManager::EstimateNativeModuleCodeSize() to find the code size estimate by default. A different code size estimate is only used in tests. * Change CompileJsToWasmWrappers() to allocate a new FixedArray instead of assuming the array was created with the correct size. This simplifies WasmModuleObject::New(), and matches what CompileToNativeModule() does. * Remove the WasmModuleObject::New() constructor that creates a NativeModule. This case was only used in DeserializeNativeModule() and in test code.

The motivating example is JetStream 2's UniPoker test, which tests whether a sorted string of Unicode playing cards contains a five-card straight using a regular expression. In the top-level generated loop for this RegExp, we see this loop exit condition: 00000350000C2067 27 83fffe cmpl rdi,0xfe 00000350000C206A 2a 0f8da8e40000 jge 00000350000D0518 <+0xe4d8> Meaning if the current position is pointing at the very last (16-bit) character, then we exit the loop. Otherwise we go on and try to find various matches starting at the current position. However, we can see in the original expression that any possible match is at least 10 characters (5 astral-plane Unicode values), so we're wasting a lot of time attempting to find matches in cases where we're too close to the end of the string for any match to succeed. This example might be a bit contrived, but I expect that an improvement in this bounds check would help a larger family of regular expressions, where the minimum match length is large relative to the string being matched and we don't meet the other necessary criteria for fast Boyer- Moore lookahead. To get the desired bounds check in this case, this patch does the following: 1. Compute accurate EatsAtLeast values for every node during the analysis phase. This could end up doing more work than the current implementation, but analysis already has to touch every node, so it seems like a cache-friendly time to compute these values. In some cases, this might be less total work than the current implementation, because the current implementation might recompute the same node multiple times. 2. When emitting a quick check, use the EatsAtLeast value from the predecessor ChoiceNode for the bounds check. This improves the UniPoker score on my machine by about 4%, because it cuts the time spent checking for straights roughly in half, and checking for straights originally accounted for about 8% of the total time.

Per the July TC39 meeting consensus, we'd like to make the upcoming String.prototype.replaceAll proposal throw for non-global RegExp searchValues. However, String.prototype.matchAll currently does not throw in this case, causing consistency concerns. This patch adds a use counter for String.prototype.matchAll with a non-global RegExp as the searchValue. Hopefully, this pattern isn't too common in real-world code today, in which case we can both a) change matchAll and b) proceed with the desired replaceAll semantics. https://github.com/tc39/proposal-string-replaceall/issues/16 V8 CL: https://chromium-review.googlesource.com/c/v8/v8/+/1718145 Chromium CL: https://chromium-review.googlesource.com/c/chromium/src/+/1718367 BUG=v8:9551 Change-Id: Ica660a0a6189d84c3d33398c98305d0bcb9f8c23 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1718145 Commit-Queue: Mathias Bynens <mathias@chromium.org> Reviewed-by:

During Module::Reset(), the module is in an unstable state between the change to SourceTextModule::code and Module::status. Any reentrancy between these points is problematic because the normal invariants about the value of SourceTextModule::code in relation to Module::status do not hold. An allocation of the exports hash table in the middle of Module::Reset() was causing reentrancy during this problematic time. This change fixes the issue by moving the allocation earlier in Reset() before any fields are modified.

Retrieving the source position for a JavaScript stack frame is a costly operation (it requires decoding the source position table). The source position is usually retrieved twice, once for the line number, and once for the column number. This CL caches the resolved source position the first time around, improving relevant stack trace serialization micro benchmarks by ~6%.

The if above asks for field_representation to have Compressed or Any Machine Representation. Therefore, it can never be Signed. The functionality doesn't change. If field_representation is Signed, it will hit the kNoWriteBarrier at the bottom.

This removes a shortcut to a "CEntryStub" from the instance object and instead loads those values via the root set which is also referenced from the instance. It makes instance objects smaller.

If we already know it has CompressedPointer representation, let's use that information to decompress more efficiently.
