      Reland^2 "[ptr-cage] Rename IsolateRoot to PtrComprCageBase" · 627b6b2f
      Shu-yu Guo authored
      This is a reland of e28dadc2
      
      The original failure was due to a stale Win32 bot. The reland failure
      was due to idempotent task deduplication returning the exact same
      failure. See crbug/1196064

      Reland "[torque] allow exported classes with custom C++ class" · bd75b0ba
      Tobias Tebbi authored
      This is a reland of 26f10ecd
      
      Change compared to original CL:
      The deserializer changes StrongDescriptorArray to DescriptorArray.
      Since this CL uses separate BodyDescriptors for the two kinds of
      descriptor arrays, this caused a DCHECK failure when the deserializer
      changes the map while the object is visited from the concurrent marking
      thread. Fix this by disabling the corresponding checks.
      
      
      Original change's description:
      > [torque] allow exported classes with custom C++ class

      [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.

      [torque][cleanup] Simplify some Torque-defined classes · e7693985
      Seth Brenith authored
      This CL is pretty mechanical; I just iterated through some Torque
      classes making the following changes:
      
      - Use @generateCppClass if it seems easy to
      - Use @generatePrint if the existing printer doesn't do anything special
      - Fix up any imprecise field types
      
      It also includes two minor changes to implementation-visitor:
      
      - Add a new -inl.h file with the things needed for
        torque-generated/class-definitions-tq.cc so we don't need to keep
        changing the compiler when we add @generateCppClass.
      - Avoid emitting incorrect accessors for ExternalPointers. This isn't
        strictly necessary for correctness, as the accessors defined in C++
        already hide the ones inherited from generated code, but it makes me
        feel safer.

      [isolate] Make field getters use a const Isolate* · 42a56e03
      Leszek Swirski authored
      To indicate that the Isolate* in getters might not be a "real" isolate,
      but rather a calculated one from GetIsolateForPtrCompr only used for
      calculating the isolate root, make that function return a const Isolate*
      and change field getters, Object::IsFoo predicates, and related
      functions to all take a const Isolate* instead of an Isolate*
      
      With this change, we can slightly more confidently use Objects that are
      in OffThreadSpace, without having to worry too much about having an
      Isolate* floating around that could accidentally be used.
      
      This is a slight abuse of const semantics, but it allows implicit
      conversion from Isolate* arguments to the const Isolate* parameter.

      [torque] Verify nested struct fields in classes · 88a2d011
      Seth Brenith authored
      As one of several steps involved in supporting struct-valued fields
      within classes, this CL generates type verification code for the data
      contained in those structs.
      
      In order to generate verification code, Torque needs to know about
      struct field offsets and the total size of structs. Those calculations
      are added to StructType itself and the function TypeVisitor::ComputeType
      which initializes the StructType. I repurposed the Field::offset value
      to behave in structs more like it does in classes (it had previously
      indicated the index of a field within a struct, but nobody used that
      value). Overall this works okay, and I think it's less confusing to have
      Field::offset mean the same thing everywhere. However, some struct
      fields have types with unknown size (Field::GetFieldSizeInformation
      fails), so those fields are now marked with offset Field::kInvalidOffset
      to indicate that the structs containing them should not be used within
      class fields or anywhere else that requires packed layout.

      This change is mostly mechanical, but it's worth mentioning a few
      slightly interesting cases:
      - A couple of field definitions didn't match the signedness of their
        corresponding accessors.
      - The generated accessors for Smi data use Smi values directly, but
        usually we want C++ accessors to use ints instead. I added a macro
        that hides the generated Smi accessors and exposes int accessors,
        but we might consider generating int accessors directly.
      - The data held in some fields is described in comments next to the
        accessor definition for those fields. With automatically generated
        accessors, those comments need a new home. In this change I put them
        in the Torque object definition, but I'm open to other suggestions.
      - gen-postmortem-metadata couldn't find updated class definitions after
        they got split across multiple lines, so I changed its matching
        logic. (Ideally debug-support.cc should be a Torque compiler output
        rather than something that involves parsing C++ with regexes, but
        this makes it correctly report subclass relationships for now.)
      - The end offsets generated by Torque were off by one from the values
        that would be generated by DEFINE_FIELD_OFFSET_CONSTANTS.
