65f3861e3b [wasm-c-api] New call descriptor and stackframe kind
So far, calls to Wasm C/C++ API functions reused the call descriptors
of WasmImportWrappers, and the stack frame type of regular Wasm
functions. This CL cleans that up by introducing separate implementations
for both. No change in functionality or performance is expected.

238dab8d2d [Tools] Update tickprocessor entry processing to work on Android symbols.
On Android libraries there are zero length entries within the ranged
symbols which break our range processing. This updates the logic to
only add entries for zero-length entries if they aren't within the range
of the previously added entry.

201c50951d [Tools] Add support to tickprocessor to symbolize libraries embedded in APKs
On Android we load the native library directly from the APK. As such,
we need to convert symbols from the mapped APK to the underlying .so
when symbolizing the ticks.

This CL adds a --apk-embedded-library argument to tick processor to enable
specifying which unstripped library file was embeded in the APK and enable
symbolizing.

70bd7cf0ef Reland "[typedarray] Move external/data pointer to JSTypedArray."
This is a reland of 4b86fea530 with
copy&paste typo in CodeStubAssembler::AllocateByteArray() fixed
(bug led to holes in new space, which was crashing reproducibly
on the ia32 bot).

4b86fea530 [typedarray] Move external/data pointer to JSTypedArray.
As the next step in supporting huge typed arrays in V8, this moves the
external/data pointer from the FixedTypedArrayBase backing store to the
JSTypedArray instance itself, and replaces the special backing stores
with a plain ByteArray (removing all the code for the FixedTypedArrayBase
class hierarchy). By doing so, we can drastically simplify the system
around typed arrays.

Note: Several places in the code base used to check the instance type
of the elements backing store of a JSTypedArray instead of checking the
elements kind on the JSTypedArray map directly. Those had to be fixed,
since the backing store is now always a ByteArray.

Drive-by-fix: Move all the typed elements access related code into the
elements.cc file to properly encapsulate the accesses.

This reverts commit 384a51da42.

This hack is both broken (builtins now have individual symbols and no
longer resolve to v8_Default_embedded_blob_) and useless (profview
seems to detect builtins just fine without it).

302a49c6b3 [logging] Systematically emit CodeCreateEvents for builtins
Introduce a single point to emit CodeCreateEvents for all builtins in
Isolate::Init. At this location, we cover both the case of builtin generation
(e.g. in mksnapshot) and deserialized builtins (in standard builds),
whereas previously we only emitted events post-builtin-generation.

In order to preserve behavior for bytecode handler events, pack the bytecode
and operand scale into our existing builtin metadata table.

Drive-by: Update way-out-of-date comment in the static initializer
check.

0dc9b63ed3 [torque] explicit exports of macros to CSA
Macros are now inaccessible from CSA except if their declaration is
marked with the "export" keyword. The implicit field accessors for class
fields are always exported.

In this CL, unwarranted access from CSA is prevented by appending a
pseudo-random suffix to non-exported names. This is to be replaced by
something more principled, namely by not including these macros at all in
the headers included from CSA.

15a7e04eec [torque] Move Map layout definition to Torque
This commit attempts to change as little behavior as possible, but it
does require reordering the fields within Map to abide by Torque rules
specifying that strong and weak fields must be in separate sections.

Also includes some Torque compiler updates:
- Allow enums (types extending from integral types) as class fields
- Rename @ifdef to @if and add @ifnot for inverse checks
- Allow void fields in class declarations, which take up no space and
  emit no accessors

41bc1cfd80 [Intl] Speed up Intl.NumberFormat constructor x4
1. Use the newer LocalizedNumberFormatter API which improve
   the performance score x3.3.
   Here are how I got the performance score:
  $ python -u tools/run_perf.py --binary-override-path \
    out/x64.release/d8 --filter "JSTests/Intl"  \
    test/js-perf-test/JSTests5.json

  Look for NewIntlNumberFormat-Intl(Score) for 3 runs.

  BEFORE: 539   507  507
   AFTER: 2009 2069 1994

2. Also add symbol and enum to prepare implementing of the unified
   number proposal.

These are added as mjsunit tests for now since they haven't been merged
to the spec repo. When that happens, the wasm-spec-tests testsuite can
be updated to include these tests, and the tests in this directory can
be removed.

This CL also adds the test/mjsunit/wasm/bulk-memory-spec directory to a
list of directories that aren't checked for copyright (since these files
are auto-generated).

- Create the closures for the private methods
- Load the brand from the context and store it in the instance in the

b3b6b5c655 [foozzie] Ignore error messages in correctness fuzzing
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.

b3e2bcf95a [tools] Default to 4 retries for all perf tests
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.

8f4063c6ea [tracing] Implement the default TracingController with Perfetto
Based on Primiano's prototype:
https://chromium-review.googlesource.com/c/v8/v8/+/1290549

This is still behind a build flag. I'll add functionality incrementally
rather than land everything in one giant CL.

This CL sets up the basic classes that will be used for the Perfetto
implementation, e.g. the producer, consumer, controller and task runner.

This implementation produces a binary proto file in the current
directory named v8_trace.proto. It doesn't yet produce JSON output,
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.

01821ab3b6 [test] Stress wasm code gc in "stress_background_compile"
The "stress_background_compile" variant runs on all our bots. We
combine it with testing wasm code GC (which kind of fits into
background compile stressing) to get more coverage for that. Both
features are orthogonal, so we can test both at the same time without
loosing any coverage.

7a70c55dc0 [tools] Replace yield-based output processing with explicit method calls
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.

3295fb7350 [tools] Add timestamps to each log line
We've originally added them in https://crrev.com/c/1159361 and then removed
again in https://crrev.com/c/1291370 since they were implemented in LogDog
Viewer. However, looks like logs from the swarming tasks are all dumped into
step stdout at the same time and thus logdog assigns idential timestamp to all
lines making it fairly useless.

a32c97cca1 [cleanup] Clean up space names in the heap
- Remove AllocationSpaceName() which was in SHOUTY_CASE and did not
  actually handle CODE_LO_SPACE.
- Make GetSpaceName() static because it is.
- Change callers of old AllocationSpaceName() to use GetSpaceName().
- Change the input type to a AllocationSpace rather than int given the
  function crashes on invalid values.

Space::name() now returns a lower case result but this is only used by
functions guarded by gc_verbose or trace_fragmentation so I don't think
this will break anything.

1ea09f0b4f [test] Ignore optimization state in tests on number fuzzer
This enable test suites to check which test driver framework is used.
When using number fuzzer on mjsunit, we add a JS file that
switches off the optimization-state assertions.

Checking intrinsic state is not feasible on the number fuzzer and in
the past, we needed to skip tests on demand, which is a maintenance
burden. The main function of the fuzzer, to check for dcheck errors and
tsan issues, is retained.

f78f43b1b9 Reland "[interpreter] Move interrupt budget from BytecodeArray to FeedbackCell"
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.

31b49aeeb0 [test] Test more wasm variants
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
more easy.

ff0b9dd30e [test] Expose variant flags in json output
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.

7629afdb9d [lite] Allocate feedback vectors lazily
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.

d6a60a0ee1 [turbofan] Significantly improve ConsString creation performance.
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.

ed34a736f1 [gcmole] Update bootstrap script for static linkage.
This changes gcmole's bootstrapping script so that it always creates
binaries that link libstdc++ statically (both plugin and Clang) and do
not link against unneeded libraries (only Clang). For deployment of
gcmole on our infrastructure, it is much easier to have fewer external
dependencies.

b240733fd5 [gdb] Add helper for creating an object from a pointer
Since the new Objects were introduced, we can no longer cast integers to
and Object pointer and call methods on them in gdb (due to how gdb's
expression evaluator deals with temporaries). So, we add a new helper
method to our gdbinit, "$job", which takes an address and returns an
Object that is now exists in real (stack) memory.

9af9a6b7e9 [gcmole] Switch assignment operator special case.
This updates the existing special casing of assignment operators by
gcmole to match for assignments of {HeapObject} instead of {HeapObject*}
variables. The former now uses the implicit C++ assignment operator call
instead of a primitive assignment binary operation.

Also removes the dead {handle_decl_name} field as a drive-by-fix.
