In assignments the lhs should be evaluated first and shouldn't be
re-evaluated when the value of the rhs is available. Fix it by
saving the receiver and the key registers into AssignmentLhsData
before building the assignment and use them later, instead of visiting
the AST again to retrieve the receiver.
In addition, now that we save the receiver register, use it to
perform the brand check even when we know for sure that it's
going to fail later because it's a write to a private
method or accessing the accessor in the wrong way (v8:11364),
so that the brand check error always appears first if it is present,
as specified in
https://tc39.es/proposal-private-methods/#sec-privatefieldget
Drive-by: unify the brand check error messages, and replace "Object"
with "Receiver" in the messages for clarity. The instance private
brand check now throws "Receiver must be an instance of class <name>"
and the static private brand check now throws "Receiver must be
class <name>". Also always set the expression position to the
property load position, because the brand check failure comes from
the load operation.

In the future we will allow arbitrary objects as host-defined options.
To prepare the embedders for the upcoming changes we migrate the API
to use v8::Data where possible.
Internally we still use i::FixedArray with primitive values until the
migration to context-stored host-defined options is completed.
Note: This CL also introduces a temporary cast and inheritance
between Data and PrimitiveArray which will be removed again.

This CL fixes a memory leak where we would not properly pop all
Promises from the Isolate-wide Promise stack. This can happen under
the following conditions:
- `await`ing a Promise in an async function
- Debugger is active
- AsyncEventDelegate is not set.
In the case above, the promise of the surrounding async function is
pushed onto the global Promise stack, but not poped before the
await. This CL fixes that.

This mechanism replaces the explicit write barrier in V8's API which

The internal barrier should also be slightly faster as it doesn't

CodeSpaceMemoryModificationScope should only be used by the main
thread and during a safepoint. This adds a check in
CodeSpaceMemoryModificationScope.
The reason for this is that CodeSpaceMemoryModificationScope is not
thread-safe. It assumes that no other thread is modifying code space
(either by setting memory permission or adding a new page).
This CL also replaces CodeSpaceMemoryModificationScope to
CodePageCollectionMemoryModificationScope in a few occurrences, where
the former is not needed. This should not hurt performance.

We enable struct.new and array.init initializer expressions in the JS
testcase generated by --wasm-fuzzer-gen-test. We needed to make some
changes in the WasmInitExpr class, and to implement a new interface for
the WasmFullDecoder, which constructs a WasmInitExpr.
Changes:
- Make WasmInitExpr a ZoneObject. Use a pointer for its operands_ field.
This is needed so WasmInitExpr is trivially copiable, and thus usable
as a Value type in WasmFullDecoder.
- Implement a WasmFullDecoder interface in wasm-fuzzer-common that
constructs a WasmInitExpr. Use it to decode initializers in the
module generated by the fuzzer.
- Change AppendInitExpr to take a WasmInitExpr as argument.
- Fix an issue with printing of struct definitions.
- Change initializer expression used for structs to struct.new_with_rtt.
This is consistent with the currently used structural types.

The wasm serialization format only contains TurboFan code. All other
functions are only represented by placeholders. With this CL
serialization fails if the serialized module does not contain any
TurboFan functions and would therefore consist only of placeholders.
This is a defense in depth approach, because ideally serialization
only gets triggered when TurboFan code is available. However, in some
scenarios like debugging it can happen that modules without TurboFan
code get serialized.

Remove the concept of JobId from LazyCompileDispatcher, and make SFIs
the canonical id for these jobs.
This has several consequences:
* We no longer split enqueing a job and registering a SFI with that
job. We did this previously because we could not allocate SFIs in
the Parser -- now with LocalHeap we can, so we do.
* We remove the separate Job vector, and make the SFI IdentityMap
hold pointers to Jobs directly. This requires a small amount of
extra care to deallocate Jobs when removing them from the map,
but it means not having to allocate new global handles for jobs.
* The SFI is passed into the BackgroundCompileTask instead of the
script, so our task finalization doesn't need the SFI anymore.
* We no longer need to iterate ParallelTasks after compiling (to
register SFIs), so we can get rid of ParallelTasks entirely and
access the dispatcher directly from the parser.
There are a few drive-bys since we're touching this code:
* Jobs are move to have a "state" variable rather than a collection
of bools, for stricter DCHECKing.
* There's no longer a set of "currently running" jobs, since this
was only used to check if a job is running, we can instead inspect
the job's state directly.

This runtime function behaves like StoreDataPropertyInLiteral, except it
can throw, since it's also used for defining public class fields. Unlike
the literal use case, class field can end up throwing due to field
initializers doing things like freezing the instance.

The goal of the PR is to add to telemetry a metric estimating the space
occupied by the codemap retained by a CpuProfiler and its underlying
CodeObserver.
This change is motivated by the addition of kEagerLogger to CpuProfiler
which when enabled let a CpuProfiler build a CodeMap without an active
session. This metric will help us understand better the space consumed
by a profiler in that scenario and will also help detect memory leaks.

Currently, the safepoint is last call instruction's return address on
mips and loongarch64 platform. But in `CallCFunction`, there are some
other instructions after calling, which leading to a wrong safepoint
record on mips and loongarch64.
So I record the pc for safepoint at the end of `CallCFunction`
function, and change `last_call_pc_` to `pc_for_safepoint_`.
Besides, commit 48b2b89176 introduced
a typo on loong64 platform, I also fixed it in this CL.

Currently, in the following struct
struct LayoutObject : GarbageCollected<>, MixinA, MixinB {};
the subobject that corresponds to the first base GarbageCollected<>
always takes up some space (one word). The empty-base-optimization
doesn't happen because the second base (MixinA) has the same subobject
as the first base (GarbageCollected), which is the most parent class
GarbageCollectedBase. The compiler can't "merge" them because it must
guarantee that distinct objects of the same type have distinct
addresses.
The attribute [[no_unique_address]] doesn't work for base classes,
unfortunately (but is a good idea for a Standard proposal). As a
solution, the CL simply removes GarbageCollectedBase.

This is a reland of 35a6eeecfa
Reland fixes:
* Add a SharedFunctionInfo::CopyFrom to encapsulate updating the SFI
from the placeholder. This now includes copying scope_info (which
wasn't included in the original CL and caused some of the issues)
* Make sure that LocalHandleScope is initialised only inside of
UnparkedScope (fixed TSAN issues)
* Clean-up: Don't add `script_` to ParseInfo, but instead pass it
separately to Parser. Eventually we'd ideally get rid of ParseInfo
entirely (splitting it into input and output) so let's not add more
fields to it. Reverts changing CreateScript to InitializeScript.

Unfortunately, CharacterRanges may use 0x10ffff as a marker value
signifying 'highest possible code unit' irrespective of whether the
regexp instance has the unicode flag or not. This value makes it
through RegExpCharacterClass::ToNode unmodified (since no surrogate
desugaring takes place without /u). Correctly mask out the 0xffff
value for purposes of building our uint16_t range array.
Note: It'd be better to never introduce 0x10ffff in the first place,
but given the irregexp pipeline's lack of hackability I hesitate to
change this - we are sure to rely on it implicitly in other spots.

This patch refactors the ClassFields benchmarks and makes the results
detection work properly. Previously the errors weren't caught since
the ClassFields benchmarks don't get run in the perf_integration
step in the CI.
- Instead of putting different configs (single/multiple fields, type
of fields, etc.)in the JSON configuration, we now group the related
benchmarks into the same script and run the different configurations
in the scripts directly. Only the optimization status is now
controlled in JSON. All the class fields definition benchmarks are
merged into initialize-class.js.
- Update the number of local iterations of evaluate-class.js to 100
(similar to most of other benchmarks) to keep the time spent on
this benchmark similar to that of other benchmarks.
In addition, copy the configs to JSTests3 so that the benchmarks gets
run by the perf_integration step and we can see the graphs on
http://chromeperf.appspot.com/report. These can be removed
when the ClassFields benchmark results are generated there too.

Port the CompilerDispatcher to use the Jobs API, instead of its own
hand-rolled worker management.
This required some re-thinking of how testing is handled, since the
tests want to be able to
a) Defer calls to PostTask/Job, to actuall post the jobs later. This
was easy enough with PostTask, since we could simply store the task
in a list and no-op, but PostJob has to return a JobHandle. The
tests now have a DelayedJobHandleWrapper, which defers all method
calls on itself, and because of all the unique_ptrs, there's also
now a SharedJobHandleWrapper.
b) Wait until tasks/jobs complete. Returning from a Task meant that
the task had completed, but this isn't necessarily the case with
JobTasks; e.g. a job might be asked to yield. This patch hacks
around this by Posting and Joining a non-owning copy of the
requested JobTask, and then re-posting it once Join returns.

TracedReferenceBase use (traced) global handles to implement the
referencs. Provide a write barrier in the corresponding handle
methods. Doing so
- avoids bugs by having embedders taking care of write barrier
management.
- speeds up the barrier as it is better integrated in the handle
methods.
Drive-by: We don't need write barriers on initializating stores.

A "store own" slow runtime was missing, and the slow handler on the
StoreOwnIC was using the non-own slow runtime function, incorrectly
causing setters to be called.
For baseline, [1] invalidates the invariant that StoreOwnIC is only used
for storing properties already in the literal boilerplate, since it's
also used when the new literal is cloned from an object spread.

When evaluating a top-level expression while paused on a breakpoint, we
don't support an await expression as top-level statement. In these
cases, the error was not informative and could be improved.
To do so, we now propagate the information from DebugEvaluate to
ParseInfo and use the parse_info in parser-base to throw a more
informative error while parsing.

Not all the SSE2 instructions can be extended to
256-bit wide AVX instructions, AVX only supports 128-bit
wide packed integer operands, while AVX2 supports both
128-bit and 256-bit wide packed integer operands. Moreover,
the 256-bit shift instructions use XMM register/m128 to store
the shift count, while all the operands of others are YMM
registers/m256 operands,so we have to divide the
SSE2_INSTRUCTION_LIST into 3 lists, packed double, packed
integer and packed integer shift.

arbitrary strings. Element accesses on module namespace objects
will be interpreted as indexed properties, so those element key

Extend type assertions to all types covering JavaScript values.
This is achieved by allocating type representations on the heap using
newly defined HeapObject subclasses. To allocate these in the compiler,
we disable concurrent compilation for the --assert-types flag for now.
Fix two type errors that came up with the existing tests:
1. JSCreateKeyValueArray has type Array (i.e., a JSArray) instead of
OtherObject.
2. OperationTyper::NumberToString(Type) can type the result as the
HeapConstant Factory::zero_string(). However, NumberToString does
not always produce this string. To avoid regressions, the CL keeps
the HeapConstant type and changes the runtime and builtin code to
always produce the canonical "0" string.
A few tests were failing because they check for truncations to work
and prevent deoptimization. However, AssertType nodes destroy all
truncations (which is by design), so these tests are incompatible
and now disabled for the assert_types variant.
Drive-by fix: a few minor Torque issues that came up.

- Introduce v8::ScriptCompiler::CompileFunction
- Deprecate v8::ScriptCompiler::CompileFunctionInContext
- Add v8::Function::GetUnboundScript
- Add v8::Script::GetResourceName
The ScriptOrModule out-parameter is only used by NodeJS since we don't
allow arbitrary objects has host-defined options and they need a way to
keep the options alive.
This CL deprecates the out-parameter and adds helper methods to
address the most common use-cases.
The final fix still requires more fundamental changes on how host-defined
options are handled.
