This reverts commit 1370b29e. Reason for revert: Breaks some targets that lack a dependency onto v8-gn.h, see https://crbug.com/1178409. Original change's description: > [build] Enable external flag header with defines > > Due to some unusual build failures on some trybots, > v8_generate_external_defines_header was reverted to false. This turns it > back on but changes the behaviour so that defines are added to the > command line as well as to the header. Because the generated header > checks that flags that should be unset are actually unset and flags that > should be set are either unset or set to 1, this will cause build > failures on many types of mismatches, although it will not detect where a > flag is not set on the command line when it is set by the header. > > If no further failures show up with this, the hybrid part can be removed > and the v8-gn.h header can stand on its own. > > Bug: v8:11292, v8:11341 > Change-Id: I1deeeebec58f79607e68a28f808649e884810923 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2649041 > Commit-Queue: Dan Elphick <delphick@chromium.org> > Reviewed-by: Michael Lippautz <mlippautz@chromium.org> > Cr-Commit-Position: refs/heads/master@{#72327} TBR=mlippautz@chromium.org,delphick@chromium.org # Not skipping CQ checks because original CL landed > 1 day ago.

We could revisit this later, but right now the direction we're going is simply keeping fast paths in the called builtins and not generating more custom inline code.

Add (ToNumber|ToNumeric)_Baseline builtins which get the feedback vector and context from the stack, perform ToNumber/ToNumeric, and update feedback. These share C++ code with Builtins::kToNumber, but don't call it directly, as they need to collect feedback as part of the conversion.

The check was a leftover from a debugging session. We don't have a feedback vector even though we have baseline code, e.g. when we share baseline code across realms. In this case the feedback vector will be allocated upon the first invocation of the function.

Add a new StackFrame class for unoptimized frames (which are either interpreted or baseline). BaselineFrame becomes a subclass of this rather than InterpretedFrame, and the various frame constants helpers are similarly amended.

This adds a call to re-compile top level functions in case no shared function info could be found.

Also block sending "type" as part of the ObjectPreview, but only send the "value" property. The front-end will be updated to display WasmValueObject's similar to what we do for wrapper objects (i.e. StringWrapper and the like). The matching front-end change is still pending. Also refactor the WasmValueObject to have dedicated constructors for the individual types (i32, i64, f32, f64, externref and v128). This way we can just reuse the existing logic in descriptionForObject() and we also don't need to store the "type" on the object itself (not really performance sensitive, but fewer moving parts / things that can go wrong). This also addresses the crash in https://crbug.com/1166077#c16 since the WasmValueObject instances now have a proper JSFunction in their maps' constructor_or_backpointer slot and are thus able to locate their creation context. Note that this doesn't generally address https://crbug.com/1166077 itself, but only the WasmValueObject case.

Instead of looking up the register holding the instance parameter, and checking that this is the constant we expected, do it the other way around: Use the constant, and check that this matches the information in the CallDescriptor. This saves a few instructions on every Liftoff function compilation. Drive-by: Move comments, checks, and code emission closer together.

This CL is part of a series that adds the C++ implementation of SwissNameDictionary, a deterministic property backing store based on Swiss Tables. This CL adds swiss-hash-table-helpers.h, which contains helpers that are mostly independent from a particular swiss table implementation (like SwissNameDIctionary) and can therefore be re-used by potential other Swiss Table implementations in the future. As a consequence of that, those helpers are largely taken unchanged from Abseil.

Previously it was possible for a slot operand to be allocated a constant operand which is not valid. This CL adds support to the mid-tier register allocator to keep track of whether spilled operands can support constant operands, and if not to instead move the constant to a spill slot at it's definition point, and use that spill slot instead. In the process of doing this, we can cleanup the hack that required constants to always be allocated to a register for REGISTER_OR_SLOT operator policies.

This is a reland of a16add80. The fixes are adding disassembly for pcmpgtq and vpcmpgtq. While fixing also noticed a mistake in assembler for pcmpgtq, which flipped dst and src. Also realized that we don't detect SSE4.2, so adding that in. PS2 contains these changes.

Port 94b294b3 Original Commit Message: Before the removal of the arguments adaptor frame, we could set {actual arguments count} = {formal parameter count} before restarting a live frame to avoid re-entering in the adaptor frame trampoline. This does not work anymore, since we now need the correct value of the {actual argument count} to be pushed in the callee frame to be used in its epilogue. This CL calls InvokeCall with the correct argument count and the kDontAdaptArgumentsSentinel to skip arguments adaptation.

As outlined in the design document linked below, we're removing the support for the non-standard Function.displayName property for the purpose of Error.stack and DevTools Inspector stack traces. The motivation here is that the negative lookup is costly, and we have Function.name as a standard alternative (configurable since ES6 for exactly this reason). I dediced to go with JSFunction::GetDebugName(), since JSFunction::GetName() was confusing in that it'd only get the "name" property's value if it's a data property, but not with accessors. JSFunction::GetDebugName() makes it clear that this is really a debug helper function and might not give you the "name" property value.

Ephemerons are based around WeakMember which may just be null at the time the pair is considered for liveness. Bail out of marking for null keys, as they write barrier would anyways make the value strong when marking the key.

The TODO around range checks for LAST_JS_RECEIVER_TYPE is guarded by a STATIC_ASSERT, so it can be a comment rather than a TODO.
