When selecting the frame above the V8_Dcheck method (at the DCHECK
location), it helps enormously to immediately see the error message
generated by the DCHECK. This extends the dcheck_stop_handler to find
and print this message.
Drive-by: Speed up the handler by stopping after the first V8_Dcheck
frame.

This is purely a renaming change. The ES spec uses the term 'detach'
for the process of removing the backing store of a typed array, while
V8 uses the historical term 'neuter'. Update our internal implementation,
including method names and flag names, to match the spec.
Note that some error messages still use the term 'neuter' since error
messages are asserted by some embedder tests, like layout tests.

Intrinsic changes:
- Rename %RawCast to %RawObjectCast and add error checking so that it
only applies to subtypes of Objects.
- Add %RawPointerCast, which is similar to %RawObjectCast but must be
used for all subtypes of RawPtr.
- Add %RawConstexprCast, which allows one constexpr to be be cast to
another at compile time. It translate to an appropriate static_cast
in the generated code
- Add %FromConstexpr, which handles most of the standard cases of
generating XXXConstant CSA nodes from constexpr constants. It uses
either SmiConstant, NumberConstant, StringConstant, IntPtrConstant
or Int32Constant, depending on the cast-to type generic <To> type.
- Add support for intrinsics that return constexpr results.
Cleanup:
- Turn FromConstexpr into a generic with two generic types, a <To> and
a <From> type. Most FromConstexpr can use the new %FromConstexpr
intrinsic rather than provide an explicit implementation.

We recently changed embedded builtins to be emitted as raw assembly

don't support large data streams well and can take over 5 minutes for

Moves allocation of the WasmModuleObject for asm.js code out of SyncCompileTranslatedAsmJS

and the WasmModuleObject requires a native context. Instead save the members required to
create the object in the AsmWasmData and create it during module instantiation. Note:
since the Wasm module is an implementation detail for asm_wasm code and isn't exposed,
this doeesn't have semantic change for asm.js code.
As part of this change, the AsmWasmData is changed from a FixedArray to a dedicated
struct. Some logic is also moved from module-compiler to wasm-engine to make the
seperation between Wasm SyncCompile and AsmJS SyncCompile more clear.

This enables more seamless interop between Torque and CSA:
Since CodeStubAssembler can now inherit from the Torque base namespace,
macros defined in the base namespace can be used in CodeStubAssembler
macros, even without qualification.
At the same time, macros in the base namespace can refer to
CodeStubAssembler macros. The only new limitation is that types defined
in code-stub-assembler.h cannot be referenced in the signature of macros
defined in the base namespace, since this would produce a cyclic header
dependency. A work-around for this woud be to put such types (like int31
in this CL) into a separate header included by both. I (mis-)used
code-assembler.h for that.
Another side-effec is that types and enums defined in CodeStubAssembler
have to be accessed in a qualified way from Torque.
Other assemblers can now inherit from their Torque equivalent, so
porting macros into the corresponding Torque namespace doesn't require
any change to the existing use-sites.
To avoid C++ ambiguities, the Torque-generated assemblers must not define
anything also defined in Code(Stub)Assembler. This includes the type
aliases for TNode, PLabel, ...
My workaround is to qualify everything in the generated C++.
As a drive-by fix, I had to change the formatter to avoid a situation
where it doesn't compute a fixed point: putting a keyword at the
beginning of a line removes the '\s' in front of it, so I replaced that
with '\b'.

change "Also forces all non-trampoline RelocInfo ByteArrays for builtins
to be generated into RO_SPACE."
Creates a single RelocInfo to be used by all builtin trampolines and
stores it as a root. All trampolines then substitute this for their
trampoline at generation time with DCHECKs to make sure it is
identical.
On x64, this results in the OLD_SPACE part of the startup snapshot
decreasing in size from 165656 to 130808 (-34848) bytes and RO_SPACE
(in the read-only snapshot) increasing from 31248 to 31272 (+24) bytes.

Creates a single RelocInfo to be used by all builtin trampolines and
stores it as a root. All trampolines then substitute this for their
trampoline at generation time with DCHECKs to make sure it is
identical.
Also forces all non-trampoline RelocInfo ByteArrays for builtins to be
generated into RO_SPACE.
On x64, this results in the OLD_SPACE part of the startup snapshot
decreasing in size from 166096 to 131248 (-34848) bytes and RO_SPACE
(in the read-only snapshot) increasing from 31176 to 31248 (+72) bytes.

Many parts of the old JS implementation are preserved, because
TypedArray.p.join still relies on it. These will be removed once
TypedArray.p.join is ported to Torque.
To simplify implementation, special handling of extremely sparse arrays
has been removed.
Performance improvements vary by array size, elements, and sparse-ness.

The implicit parameter syntax adds a second parameter list
before the explicit parameter list when declaring macros, builtins and
runtime functions:
extern macro MyMacro(implicit a: Smi)(b: Oddball);
when calling the macro, only the formal parameters can be provided
at the call site. The implicit parameters are implicitly looked-up
by name in the scope of the call and prepended to the explicit parameter
list. The values that are found by name for each implicit parameter must
be castable the corresponding implicit parameter type:
MyMacro(Null); // Error, a is not defined
...
const a: Smi = 0;
MyMacro(Null); // OK
...
const a: Object = 0;
MyMacro(Null); // Error, a has wrong type
For external macros, builtins and runtime functions, the formal
parameter list expected on the C++ side is the concatenation of the
implicit and explicit parameter lists.
As a drive-by: fix the formatting of typeswitch statements in the
the presence of deferred-marked blocks and funky white space.

This JSAsyncFunctionObject represents the implicit generator object
inside of async functions, and also holds the outer promise for the
async functions. This in turn allows us to get rid of the .promise
in the Parser / BytecodeGenerator completely, and will make it
possible to build zero-cost async stack traces independent of the
concrete synchronous part of the stack frame (which currently breaks
in Node.js).
In the bytecode all the async function operations now take this new
JSAsyncFunctionObject instead of passing both the .generator_object
and the .promise, which further simplifies and shrinks the bytecode.
It also reduces the size of async function frames, potentially making
the suspend/resume cheaper.
This also changes `await` to use intrinsics instead of calling to
special JSFunctions on the native context, and thus reduces the size of
the native contexts.
Drive-by-fix: Introduce a dedicated JSCreateAsyncFunctionObject operator
to TurboFan.

The MapIterator protector protects the original iteration behaviors of
Map.prototype.keys(), Map.prototype.values(), and Set.prototype.entries().
It does not protect the original iteration behavior of
Map.prototype[Symbol.iterator](). The protector is invalidated when:
* The 'next' property is set on an object where the property holder is the
%MapIteratorPrototype% (e.g. because the object is that very prototype).
* The 'Symbol.iterator' property is set on an object where the property
holder is the %IteratorPrototype%. Note that this also invalidates the
SetIterator protector (see below).
The SetIterator protector protects the original iteration behavior of
Set.prototype.keys(), Set.prototype.values(), Set.prototype.entries(),
and Set.prototype[Symbol.iterator](). The protector is invalidated when:
* The 'next' property is set on an object where the property holder is the
%SetIteratorPrototype% (e.g. because the object is that very prototype).
* The 'Symbol.iterator' property is set on an object where the property
holder is the %SetPrototype% OR %IteratorPrototype%. This means that
setting Symbol.iterator on a MapIterator object can also invalidate the
SetIterator protector, and vice versa, setting Symbol.iterator on a
SetIterator object can also invalidate the MapIterator. This is an over-
approximation for the sake of simplicity.

Change the way that the (internal) await closures store the link to the
generator object by introducing a dedicated AwaitContext, which stores
the generator object into the extension slot (instead of misusing a
regular FunctionContext here). Also unify the allocation+initialization
of these contexts in the await-related builtins (both for async functions
and generators).
The rationale behind this is that for (zero-cost) async stack traces, we
will need to dig into these contexts and we can do better checking with
a dedicated instance type there. As an additional benefit, we save one
word per await context, since we just use (the otherwise unused) extension
slot to remember the generator object. As yet another benefit we will
never accidentally use any of these contexts in the regular scope chain
lookups, meaning we can also catch bugs there. And last but not least
the objects printing machinery understands these contexts now and can
even print the generator object for AwaitContexts for short printing,
which is really valuable for debugging.

The Parser inserts a temporary .promise variable to hold the outer
promise for async functions, but doesn't assign an actually visible
name to it. This change puts the name ".promise" on it (similar to
what we do for other special variables like .result), which makes it
easier to debug this (for V8 developers). It's not observable to
regular developers.

Issues/problems addressed:
- Fix line-wrapping and indenting for long declarations including strings,
e.g. generates and constexpr clauses.
- Implement proper formatting for typeswitch statements
- Fix formatting of operator declarations
- Fix formatting of constexpr if-clauses (the constexpr is now included on the
same line as the if and it doesn't mess up the formatting that
- Fix formatting of label declarations on callables, the "label" keyword now
always starts a new line with indentation.
- Remove space after identifier name in generic parameter declarations, e.g.
"<a : T>" is now "<a: T>" which is consistent with type specification
formatting elsewhere.
- Indent "otherwise" clauses that have been pushed to the next line.
Also ran the formatter over all existing .tq files.

Cleanup the JSArrayBuffer bit fields to use the proper object macros
that are now otherwise used consistently across the code base. Also
change TurboFan to consistently bailout when it sees an array buffer
that was previously neutered, so that the generic path / builtins are
again the chokepoints for the spec violations (the fact that we don't
always raise exceptions when we see a neutered array buffer), except
for the ArrayBufferView accessor inlining in the JSCallReducer, where
we still turn the values into zero (because we don't have access to
a CALL_IC speculation guard in the common case).
This also removes the ArrayBufferWasNeutered simplified operator, and
does regular LoadField + Number bitwise operations instead, which is
good enough and allows us to get rid of a lot of unnecessary complexity.

If profiling is done with --log-source-code profview will now display
a "View source" link for each function in the tree view. Clicking this
will show a new source viewer, with sampled lines highlighted. See the

This patch also fixes a bug in the profiler where the source info of
only the first code object for each function would be logged, and
includes some refactoring.

When switching log files, if a function was selected the timeline would
attempt to draw its ticks and would usually crash. It would also
preserve the selected section of the timeline.
This patch wipes out the current state when loading a new log file,
with the exception of the current mode (Summary, Bottom up, etc). As a
consequence, the timeline size is now calculated in TimelineView.render
so it will always be drawn at the right size.

This patch ports most of the Intl.Collator from JS to C++.
The Intl.Collator object no longer stores all the resolved
values. Instead these are looked up on demand as part of
Intl.Collator.prototype.resolvedOptions(), saving several words. In
the future, we can cache the result of the resolvedOptions as well.
In this patch, we use ICU to do parsing of the unicode extension in
the bcp47 language tag instead of using a custom extension parser.
This patch also fixes several spec compliance bugs as well.

Previously, Intl.PluralRules was mostly implemented in JavaScript. This
patch moves most of the constructor and parts of other methods to C++.
The size of the Intl.PluralRules object is reduced by not storing
MinimumIntegerDigits, MinimumFractionDigits, MaximumFractionDigits,
MinimumSignificantDigits, MaximumSignificantDigits. Instead these are
looked up from icu::DecimalFormat as required.
Another optimziation is that we don't create the result of
resolvedOptions when the Intl.PluralRules object is constructed, but
instead defer until this method is called. In the future, we may want
to cache the result.
This patch also cleans up several error handling paths that shouldn't
happen with ICU and instead just crashes should it ever happen.

it finds on disk. Using Python's "fnmatch" for this nicely handles
wildcards, but is relatively slow. For given test names that don't
contain any '*', we can use string equality testing, which is much
faster.
Example: the time to evaluate

sed -E 's|\.js$||' | \

For checks and assertions (mostly for debug code, like stack alignment
or zero extension), we had two modes: Emit a call to the {Abort}
runtime function (the default), and emit a debug break (used for
testing, enabled via --trap-on-abort).
In wasm, where we cannot just call a runtime function because code must
be isolate independent, we always used the trap-on-abort behaviour.
This causes problems for our fuzzers, which do not catch SIGTRAP, and
hence do not detect debug code failures.
This CL introduces a third mode ("hard abort"), which calls a C
function via {ExternalReference}. The C function still outputs the
abort reason, but does not print the stack trace. It then aborts via
"OS::Abort", just like the runtime function.
This will allow fuzzers to detect the crash and even find a nice error
message.
Even though this looks like a lot of code churn, it is actually not.
Most added lines are new tests, and other changes are minimal.

The most important point of IWYU (include-what-you-use) is that each
header includes everything it is using, so that whoever includes that
header does not need to additionally include other things.
This CL adds a script which generates files to automatically check this.
It is automatically invoked during "gclient runhooks" if the
"check_v8_header_includes" variable is set. This script generates a
number of .cc files in the "check-header-includes" directory, together
with a "sources.gni" file which lists all the generated cc files. Each
file includes one header.
If additionally the gn args "v8_check_header_includes" is set, this gni
file is included, and all the generated CC files will be compiled. This
will detect violations of the aforementioned IWYU rule.

Instead of having a separate liftoff config, which is tested against
the default (which currently means tier-up from liftoff to turbofan),
just choose reasonable liftoff configs for the existing configs.
'ignition' now implies pure liftoff execution.
'ignition_turbo_opt' always compiles with turbofan.
Other configs use the default (tier up).

term this object will be accessed via a global variable without

Moves the list macros in heap.h to roots.h and splits some of them into

Adds a instance types for each HashTable subtype, rather than reusing
HASH_TABLE_TYPE. This allows us to check for these types by checking
the instance type directly, rather than by comparing against the map in
the root set.
Also, as a drive-by, do the same for SCRIPT_CONTEXT_TABLE_TYPE, and use
instance type checks rather than map checks for Context types.
This is a good general clean-up, but in particular is intended for
GetIsolate removal.

All Object::Print functions now take an Isolate* parameter. Various
XX::XXPrint functions now take an Isolate if it's needed rather than
calling GetIsolate(). Such method use DECL_PRINTER_WITH_ISOLATE rather
than DECL_PRINTER.
The _v8_internal_Print_ function (intended for use in gdb) now uses
Isolate::Current() to get hold of an Isolate.
Reduces the GetIsolate and GetHeap count by 9 and 5 respectively.
Also removes unneeded gdb/lldb macros (along with their support
functions), jfv, jfm, jda and jta, since job does the same thing.

For now we keep params since NewSloppyArguments uses it to figure out how to structure the arguments object. We should be able to only keep params in case we have a special case though. E.g., leaf functions with no duplicate parameters don't need special treatment. Or we simply encode the parameter index for each context slot. (I'm not sure duplicates need special treatment.)

this objective has no real value, and we already store some internal

Curiously, npm created a 'package-lock.json', which is ~500 lines, and
which is supposed to be checked into the repository according to documentation.

This is a reland of 91bab5588c
This CL contains two major changes w.r.t to the original CL:
The random state is removed from the Smi root list and we pre-seed the RNG
on each sort with the length of the array.
To cut down on the length of the arguments list and to keep track of the
random state across recursive calls, we move most of the sort arguments into
a FixedArray and reload from the array for each recursion.

This makes the WasmCompileLazy builtin push a new WASM_COMPILE_LAZY
frame type. We can thereby remove the workaround to return a relocated
instance from the underlying runtime function. It also removes the last
remaining embedded code objects from {WasmCode} objects.

This CL adds support for inlined functions in Turbolizer. It is also a
refactoring of the Turbolizer code-base. Most importantly, handling of
source positions changed to exact source positions, and not code ranges.
This improves selection interoperability between different phase views.
A separate CL changes the Turbolizer JSON format to include inlining
information. This Turbolizer update, however, is intended to be backwards
compatible with the JSON format Turbolizer generated before the JSON
format change.

This is needed since depot_tools may not be in PATH on LUCI bots. Using the copy
of depot_tools that contains the recipes is also incorrect as it is not
guaranteed to contain binaries that do not have corresponding recipe API, which
does not apply to script called from a recipe. This also protects our release
scripts from breaking due to arbitrary changes to depot_tools.
Chromium also pins depot_tools for similar reasons:

There are likely cleanups that can be done after this CL:
- context-related functions in the interpreter and compiler take ScopeInfo as
well as ScopeType and slot-count as input. The latter 2 should be directly
derived from the former. We should be able to drop FunctionContextParameters.
- ContextExtension is probably not needed anymore, since we now always have the
correct scope_info directly in the SCOPE_INFO_INDEX slot.

the Code object currently being generated) as references to a temporary

embedded in the generated code.
This adds support for this mechanism to the builtins constants table

This CL implements TypedArray.p.sort in Torque. The Torque
version works basically the same as the existing JS builtin:
When no comparison function is provided, the C++ fast path builtin
is used. Otherwise a quicksort written in Torque is used, with
a InsertionSort fallback for smaller arrays.
The JS quicksort implementation also containes a more elaborate
third pivot calculation for larger arrays. This is currently not done.
Reported benchmark results are only for those, where a custom
comparison function is provided. The numbers for the C++ path stayed
the same.

Previously, there was one species protector for Array, TypedArray and
Promise. This CL splits the protector in three separate ones. This means
that invalidating one of them does not have negative performance
implications for the other ones.

When attributing ticks to a function, we first check if the current pc
matches a section within the dynamic library. If we find a match here,
then we don't continue looking within dynamically generated range
information, e.g. for JS functions and builtins.
This logic breaks when embedded builtins come into play. They live
within the libv8.so shared library, and are found when looking up
statics. But what we really want is to look up the dynamically
generated code-range, which contains more precise information.
In this CL, this case is detected by matching the found symbol name.
If it's the embedded blob, then we continue to dynamic lookup.

This makes testing with random gc stress use the status file entrees
for gc fuzzing as well, since many test cases not suitable for one, are
not suitable for the other.
This also skips two more tests that rely on assert(Un)Optimized, which
is unreliable with gc fuzzing.

This is relevent for when the only "git" in your PATH is git.bat (from
depot_tools). I'd guess this is pretty common for Googlers.

Minidumps could potentially contain sensitive information, so we
shouldn't be serving them to the world.
