      [Torque] Finalize torque-generated synchronized accessors · 8da583ee
      Nico Hartmann authored 
      Torque-generated relaxed/acquire/release accessors now expect an
additional Tag argument to be more consistent with handwritten
accessors.

Torque's annotations are renamed from @relaxedRead, @relaxedWrite,
@acquireRead and @releaseWrite to @cppRelaxedLoad, @cppRelaxedStore,
@cppAcquireLoad and @cppReleaseStore, repesectively. This renaming
shall better reflect the fact that those annotations just generate
corresponding synchronization on the generated C++ accessors
(not CSA code) and be more consistent with the C++ side of things
where "Load" and "Store" is used instead of "Read" and "Write".

This CL uses these new annotations on a few fields in DebugInfo and
FunctionTemplateInfo to have Torque generate accessors automatically.

      [compiler] Support GetPropertyAccessInfo in a concurrent setting · 1277bb5c
      Jakob Gruber authored 
      Until this CL, the JSHeapBroker::GetPropertyAccessInfo (GPAI) process
was as follows:

 1. GPAI is called on the main thread (MT) during the serialization
    phase to create and cache PAIs.
 2. GPAI is called again from the background thread (BT); only cached
    PAIs from step 1 are usable.

As part of concurrent inlining, the goal is to move GPAI fully to the
background thread. This CL takes a major step in that direction by
making GPAI itself callable from the BT without resorting solely to PAIs
that were previously cached on the MT.

There are two main reasons why GPAI previously had to run on the MT:

 a) Concurrent access to Maps and other heap objects.
 b) Serialization and creation of ObjectRefs for objects discovered
    during GPAI.

This CL addresses only reason a) and leaves b) for future work. This
is done by keeping the two-pass approach, s.t. the initial call of
GPAI on the MT discovers and serializes objects. We then clear all
cached PAIs. The second call of GPAI on the BT thus runs full logic in a
concurrent setting.

Once all relevant objects (= maps and prototypes) no longer require
MT-serialization, reason b) is also addressed and the first pass can be
removed.

The new logic is implemented behind the runtime flag
--turbo-concurrent-get-property-access-info (default true), intended
to be removed in the future.

      Reland "[fastcall] Add support for leaf interface type checks" · 5540fbfc
      Maya Lekova authored 
      This is a reland of 6124a534

It fixes a UAF issue in the d8 test by moving the test API object
constructor to PerIsolateData. It also fixes a crash in Chromium
caused by current usage of v8::ApiObject, which should be migrated
to v8::Value*.

Original change's description:

      Check published FunctionTemplateInfo is immutable · 1040aef3
      Nico Hartmann authored 
      This CL generalized the previous check that a FunctionTemplateInfo
instance is not changed after being instantiated to a check for
immutability after being published. A FTI is considered published once
it is instantiated (set in a SharedFunctionInfo) or set as an accessor
on a JSObject. The published state is tracked in the flags field.
TurboFan relies on this immutabilty for concurrent access.

The immutability requirement was already met before this CL, but this
change enforces this by adding necessary checks.

      [torque] generate C++ class definitions per Torque file · 03f60296
      Tobias Tebbi authored 
      This CL splits the class definitions per .tq file, to realize the
following relationship:
A class defined in src/objects/foo.tq has a C++ definition in
src/objects/foo.h. Torque then generates:

- torque-generated/src/objects/foo-tq.inc
  An include file (no proper header) to be included in src/objects/foo.h
  containing the Torque-generated C++ class definition.

- torque-generated/src/objects/foo-tq-inl.inc
  An include file (no proper header) to be included in
  src/objects/foo-inl.h containing inline function definitions.

- torque-generated/src/objects/foo-tq.cc
  A source file including src/objects/foo-inl.h that contains non-inline
  function definitions.

Advantages of this approach:
- Avoid big monolithic headers and preserve the work that went into
  splitting objects.h
- Moving a definition to Torque keeps everything in the same place
  from a C++ viewpoint, including a fully Torque-generated C++ class
  definition.
- The Torque-generated include files do not need to be independent
  headers, necessary includes or forward declarations can just be added
  to the headers that include them.

Drive-by changes:
A bunch of definitions and files had to be moved or created to realize
a consistent 1:1 relationship between .tq files and C++ headers.

      This is to establish a naming rule for Torque-generated files:
- If the file is called foo/bar-tq..., then it is derived from a
  file foo/bar.tq
- Otherwise it doesn't belong to a specific .tq file.

So far, we attached -tq to all Torque-generated file names, where it
sometimes corresponded to a .tq file name and sometimes not.
It is not necessary to add -tq to file names to indicate that they are
Torque-generated, since they are already in a directory called
torque-generated, and we always refer to them as
"torque-generated/filename", so there is no confusion even though some
files now have the same name as a corresponding hand-written file, for
example factory.cc.

      [offthread] Change OffThreadIsolate to LocalIsolate · f1589bbe
      Leszek Swirski authored 
      This patch introduces a new LocalIsolate and LocalFactory, which use
LocalHeap and replace OffThreadIsolate and OffThreadFactory. This allows
us to remove those classes, as well as the related OffThreadSpace,
OffThreadLargeObjectSpace, OffThreadHeap, and OffThreadTransferHandle.
OffThreadLogger becomes LocalLogger.

LocalHeap behaves more like Heap than OffThreadHeap did, so this allows
us to additionally remove the concept of "Finish" and "Publish" that the
OffThreadIsolate had, and allows us to internalize strings directly with
the newly-concurrent string table (where the implementation can now move
to FactoryBase).

This patch also removes the off-thread support from the deserializer
entirely, as well as removing the LocalIsolateWrapper which allowed
run-time distinction between Isolate and OffThreadIsolate. LocalHeap
doesn't support the reservation model used by the deserializer, and we
will likely move the deserializer to use LocalIsolate unconditionally
once we figure out the details of how to do this.

      Revert "[torque][cleanup] Use more precise field types in a few classes" · 16cb2d94
      Seth Brenith authored 
      This reverts commit 4e5fabae.

Reason for revert: performance regressions chromium:1085305, chromium:1084978

Original change's description:
> [torque][cleanup] Use more precise field types in a few classes
> 
> This change updates some Torque-defined classes to include more precise
> field types where possible. It also updates those classes to use
> @generateCppClass. One field was removed because it's unused
> (PrototypeInfo::validity_cell), and two fields in StackFrameInfo
> actually became less precise because they're based on Script::name,
> which is an embedder-provided untyped Local<Value>. (Automatically
> generated accessors pointed out this bug easily.)
> 
> This change also includes a couple of minor fixes in Torque.
