This patch implements the declarations of private methods, the access
of private methods would be left to a future patch.
When a private methods declaration is encountered, we now:
- Create a brand symbol during class evaluation and store it in the
context.
- Create the closures for the private methods
- Load the brand from the context and store it in the instance in the
constructor.

Error messages are unspecified in JavaScript and occasional small
differences in the compared configurations lead to an unjustified
maintenance burden of correctness-fuzzing issues.
This CL replaces most error messages with a fixed suppression
message during correctness fuzzing (behind a flag).
The flag covering all extra behavior for correctness fuzzing is now
renamed to --correctness-fuzzer-suppressions.

Overall, total test runtime that was wasted due to timeouts is 3420 seconds in
the last 2 weeks. Even with 4 retries, assuming all of them time out, needed
additional capacity is under 2 hours per week. Based on this analysis, I think
it's safe to land this CL.
Note that this is not intended as a long-term solution of the timeout problem,
but rather a temporary solution to prevent ongoing errors. Proper investigation
and correct long-term solution are still needed and tracked in the bug.

This CL sets up the basic classes that will be used for the Perfetto

This implementation produces a binary proto file in the current

that is coming in a following CL.
Currently the old tracing and perfetto tracing are both run alongside
each other if the build flag is enabled.

This also makes processing immediate, i.e. outputs are parsed into results as
soon as test run is finished, which will allow us to implement logic that checks
whether we have enough runs based on already-accumulated results.
Since we process each output immediately, we do not need Measurement class any
longer and its ConsumeOutput is now integrated directly into TraceConfig.
Similarly AccumulateResults is replaced with RunnableConfig.ProcessOutput as we
do not accumulate results any longer.

This is a reland of Ie3ac389e1c082d1671efd4d74abc076ce943301b with a fix
for MSAN failures.
Interrupt budget was store in bytecode array and used to be shared
across all contexts. With lazy feedback allocation, using context
independent interrupt budget might lead to performance cliffs when
we have closures that do not share the same feedback (for ex: across
contexts). This would be a problem even earlier but it could be
more pronounced with feedback vector allocation, since the budgets
for optimization is much higher (144x) than the budget for feedback
allocation.

Interrupt budget was store in bytecode array and used to be shared

independent interrupt budget might lead to performance cliffs when
we have closures that do not share the same feedback (for ex: across

Since wasm optimizations are independent of JS optimizations, we can
just combine the "no_liftoff" variant with the existing "stress"
variant (which has the similar "--always-opt" option for JS), and add
a "Liftoff only" variant as part of "nooptimization".
This gives more coverage to find bugs like https://crrev.com/c/1543354

For standard test failures, the variant name is enough to deduce the
full command line of the test. This is used to create the flako
command line on the infra side.
Test failures from numfuzz have additional variant_flags, calculated
by the fuzzer, which don't match a variant name. Exposing those in
the test results will enable printing a proper flako command line
on infra side for numfuzz cases.

Allocate feedback vectors lazily when the function's interrupt budget has
reached a specified threshold. This cl introduces a new field in the
ClosureFeedbackCellArray to track the interrupt budget for allocating
feedback vectors. Using the interrupt budget on the bytecode array could
cause problems when there are closures across native contexts and we may
delay allocating feedback vectors in one of them causing unexpected
performance cliffs. In the long term we may want to remove interrupt budget
from bytecode array and use context specific budget for tiering up decisions
as well.

This change significantly improves the performance of string
concatenation in optimized code for the case where the resulting string
is represented as a ConsString. On the relevant test cases we go from
serializeNaive: 10762 ms.
serializeClever: 7813 ms.
serializeConcat: 10271 ms.
to
serializeNaive: 10278 ms.
serializeClever: 5533 ms.
serializeConcat: 10310 ms.
which represents a 30% improvement on the "clever" benchmark, which
tests specifically the ConsString creation performance.
This was accomplished via a couple of different steps, which are briefly
outlined here:
1. The empty_string gets its own map, so that we can easily recognize
and handle it appropriately in the TurboFan type system. This
allows us to express (and assert) that the inputs to NewConsString
are non-empty strings, making sure that TurboFan no longer creates
"crippled ConsStrings" with empty left or right hand sides.
2. Further split the existing String types in TurboFan to be able to
distinguish between OneByte and TwoByte strings on the type system
level. This allows us to avoid having to dynamically lookup the
resulting ConsString map in case of ConsString creation (i.e. when
we know that both input strings are OneByte strings or at least
one of the input strings is TwoByte).
3. We also introduced more finegrained feedback for the Add bytecode
in the interpreter, having it collect feedback about ConsStrings,
specifically ConsOneByteString and ConsTwoByteString. This feedback
can be used by TurboFan to only inline the relevant code for what
was seen so far. This allows us to remove the Octane/Splay specific
magic in JSTypedLowering to detect ConsString creation, and instead
purely rely on the feedback of what was seen so far (also making it
possible to change the semantics of NewConsString to be a low-level
operator, which is only introduced in SimplifiedLowering by looking
at the input types of StringConcat).
4. On top of the before mentioned type and interpreter changes we added
new operators CheckNonEmptyString, CheckNonEmptyOneByteString, and
CheckNonEmptyTwoByteString, which perform the appropriate (dynamic)
checks.
There are several more improvements that are possible based on this, but
since the change was already quite big, we decided not to put everything
into the first change, but do some follow up tweaks to the type system,
and builtin optimizations later.

This updates the existing bootstrap.sh script for gcmole to work against

After introducing the new pointer-containing Object class in V8 (see
https://docs.google.com/document/d/1_w49sakC1XM1OptjTurBDqO86NE16FH8LwbeUAtrbCo/edit),
gcmole stopped finding errorneous usage of raw pointers in functions that could
trigger GC. This CL modifies the heuristics of the tool to classify Object and
MaybeObject instances as raw pointers, thus giving back the missing warnings.
Updated the gcmole implementation to support modern llvm (tested with llvm 8.0)
for which additional support for MaterializeTemporaryExpr, ExprWithCleanups and
UnaryExprOrTypeTraitExpr was needed.
Basic tests are added to make it harder to introduce such errors without
noticing in the future.
This version gives a lot of false positives when ran on the whole project, see

In the early days of Chrome when we used WebKit there was no support for
ASCII strings on the C++ side, so we put a hint onto these two-byte
strings that said "string only contains one byte data", such that
internally in V8 when these were involved in string operations, we could
instead create the *cheaper* one byte strings.
Nowadays Blink properly supports one-byte string representations and
this additional hint only comes with overhead, since we check it in
quite a few places (i.e. on the hot path for string concatenation), plus
we end up consuming more memory due to the additional string maps.
Removing the hint also frees one bit in the InstanceType zoo for
strings.
This alone improves performance on the `bench-dom-serialize.js` test case
by around **3%**.

I thought about potentially adding the identifer ref to the error but
that would require allocating a new string or at the very least
increasing the size of the resulting cons string. Given that the
parser is pretty performance sensitive, I've decided to not display
the identifier.

_test.js:3: Error
a[foo].c = () => { throw Error(); };

Error
at a.(anonymous function).c (_test.js:3:26)

The initial prototype consists of a few parts:
The VS Code extension is now built using TypeScript. The build artifact
is checked-in along side the extension. The extension now starts up
the language server when it is activated. The path to the LS
executable is configurable via VS Code settings.
The language server is a separate executable. It adds a light-weight
object model on top of a Json Parser for reading/writing LSP requests
and responses. The current server is very much bare-bones featurewise:
- Tell the client that the server can handle "goto definition"
- Recompile when Torque files change
- Goto definition support for Macros/Builtins, local variables
and arguments.

Presubmit script is run before every 'git cl upload', the workflow will make
sure that the upload is canceled, but the files are formatted.

V8 test suites return tests by loading them into memory up-front. Up-front
loading has memory and loading-time overhead for the testrunner.
This CL converts the test-suites to load tests during the test run in parallel.
After CL, most test suites start running immediately and all test suites start
running after 3 seconds on a modern SSD.
This CL eliminates the 200 MiB memory spikes that causes memory problems in mac
minis.

Class positions is a struct that stores the start and end positions of a class
literal. It is stored both on class objects, and the template used to
instantiate class objects.
The template is reachable from the bytecode array and therefore serialized by
the startup serializer. Class objects are context-dependent and therefore

map for JSObject. To do this, allocation is now split into two
instrinsics, one that calculates the base size of the allocated object
(%GetAllocationBaseSize) and one that actually allocates (%Allocate).
In the process, remove objects.tq, which only existed to contain a
macro to fetch the default JSObject map, which is functionality that
is now in the JSObject class constructor.

Now, the CodeAssembler can annotate Nodes with SourcePositions.
SourcePositions themselves get a new mode "external," in which
they get a file_id, line and column. The file_id is currently
maintained in the isolate, mapping to strings for filenames.
Additionally, inlining information is ignored at this point,
but in the long run I'd like to recognize calls to different
CSA functions as manual inlinings.
At this point, if you want to see the results in tools like GDB,
you'll need to build without clang, and use the GCC toolchain.
GN flag is_clang=false will do the trick.

The destructor already has special handling for a {nullptr} mapping, so
we can just use {nullptr} for empty files. We get a similar error on

On order to make presubmit checks happy, we have to skip copyright

With the changes in this patch, it is now possible to add methods to
both Torque's class and struct types. As a special case, "constructor"
methods are used to initialize the values of classes and structs when
they are constructed.
The functionality in this patch includes:
- The refactoring of class- and struct-handling code to share field
and method declaration code between both.
- Addition of the "%Allocate" intrinsic that allocates raw bytes to be
allocated from the V8 GC's NewSpace heap as the basis for freshly
created, initialized class objects.
- An implementation of a CallMethodExpression AST node that enables
calling methods and constructors, including special handling of
passing through the "this" pointer for method calls on structs by
reference. The syntax for struct construction using "{}" remains as
before, but now calls the struct's matching constructor rather than
implicitly initializing the struct fields with the initialization
arguments. A new syntax for allocation classes is introduced: "new
ClassName{constructor_param1, constructor_param1, ...}", which
de-sugars to an %Allocate call followed by a call to the matching
constructor.
- class constructors can use the "super" keyword to initialize their
super class.
- If classes and struct do not have a constructor, Torque creates a
default constructor for them based on their field declarations,
where each field's initial value is assigned to a same-typed
parameter to the the default constructor. The default constructor's
parameters are in field-declaration order, and for derived classes,
the default constructor automatically uses a "super" initialization
call to initialize inherited fields.
- Class field declarations now automatically create ".field" and
".field=" operators that create CSA-compatible object accessors.
- Addition of a no-argument constructor for JSArrays that creates an
empty, PACKED_SMI_ELEMENTS JSArray using the machinery added
elsewhere in this patch.

TestSuite has a static method LoadTestSuite that should properly configure the
TestSuite instance (i.e. loaded status files and tests), however the method
leaves some configuration logic to the caller.
The leaky abstraction causes the caller to do a bunch of loading operations (see
the removed methods in base_runner.py).
This CL isolates the TestSuite loading logic to the static method only.
This is a refactoring only change without any intended logical changes.

Class declarations support structured heap data that is a subtype of
HeapObject. Only fields of Object subtypes (both strong and weak)
are currently supported (no scalar fields yet).
With this CL, both the field list macro used with the C++
DEFINE_FIELD_OFFSET_CONSTANTS macro (to make field offset constants) as
well as the Torque "operator '.field'" macros are generated for the
classes declared in Torque. This is a first step to removing the
substantial amount of duplication and boilerplate code
needed to declare heap object classes.
As a proof of concept, and handful of class field definitions,
including those for non trivial classes like JSFunction, have been
moved to Torque.
