      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.

      [api] TC39 Dynamic Code Brand checks · aabe6406
      Daniel Vogelheim authored 
      https://github.com/tc39/proposal-dynamic-code-brand-checks

An experimental implementation of the TC39 "Dynamic Code Brand Checks". This
implementation sticks an API-only symbol on each "code kind" object, which
is more flexible, but costs memory for each instance.

      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.

      [cleanup][torque] Use @generateCppClass in some simple cases, part 2 · a5811358
      Seth Brenith authored 
      This patch is mostly mechanical. A few changes in
implementation-visitor.cc might be worth mentioning:
- Don't generate both field offset macros and class definitions for the
  same class. This was mostly just to keep me from forgetting to remove
  the DEFINE_FIELD_OFFSET_CONSTANTS part when converting classes, but
  also helpfully flagged that FixedArrayBase wasn't using the generated
  class that it requested.
- Generate forward declarations for all tq-defined classes in
  internal-class-definitions-tq.h. This is helpful for making things
  compile when classes have fields of other class types.
- When generating accessors for union types, use the nearest class type
  that contains the entire union rather than plain Object. This is
  important for compile-time type safety. It also required a few minor
  fixes elsewhere (isolate.cc, modules.cc, scope-info.cc,
  source-text-module.cc, and a correction of the field types in
  CallHandlerInfo to match how they're set in api.cc).

      [objects] Shrink FunctionTemplateInfo · b0b5eae0
      Dan Elphick authored 
      Adds a new field rare_data of type FunctionTemplateRareData to
FunctionTemplateInfo and moves 8 others which are unset on 90% of
FunctionTemplateInfo objects to this field.

Getters like prototype_template() are changed to GetPrototypeTemplate()
to indicate they're not trivial. The setters are replaced with static
methods (e.g. SetPrototypeTemplate) that take an Isolate and the
template object, since they can now perform allocation.
