      [torque] Add LazyNode support · ede27407
      Seth Brenith authored
      This change adds a new abstract type Lazy<T> which can be used to
      interoperate with CSA code that uses LazyNode. This new type has special
      code-generation rules because its generated type is not TNode<...> but
      std::function<TNode<...>()>. Torque code can do nothing with this type
      except pass it around, but passing it to the CSA function RunLazy is an
      easy way to execute the std::function and get back a normal value.
      Torque code can also create Lazy<T> values using the intrinsic function
      %MakeLazy, which takes the name of a macro as its first parameter,
      followed by arguments to that macro which will be passed when the
      LazyNode is evaluated. We use the macro's name because the language
      doesn't support taking references to macros, and implementing such a
      feature would be complicated.

      [torque] Unused implicit parameters can be undefined · 9bd8e5f2
      Daniel Clifford authored
      e.g. the following is now valid Torque code:
      
        macro TestA(implicit c: Context)() {}
      
        macro TestB(): bool {
          return TestA();
        }
      
      This is handy for more flexible usage of generics that may or may not
      use implicit parameters deep inside their specializations.
      
      Note that this change doesn't change the fundamental rigor (or lack
      thereof) around checking the usage of implicit parameters, which
      already do not require '_' before their parameter identifier if
      unused. It just silences errors in cases where a call site doesn't
      implicitly pass a parameter that ultimately doesn't have a use site
      and adds meaningful error messages in the case that it does.

      [torque] generate Cast<> macros from Torque-defined classes · 1052dfb3
      Daniel Clifford authored
      This change enables automatic generation of Cast<> operators for
      classes that are defined in Torque.
      
      * Cast<> macros are generated for all classes that are defined in
        Torque code that are neither shapes nor marked with a new
        @doNotGenerateCast annotation.
      
      * Implicitly generated Cast macros simply call through to an
        internally-defined "DownCastForTorqueClass" macro that implements
        the cast using one of three strategies for efficiency. If the class
        has subclasses (i.e. a range of instance types including subtypes),
        the DownCastForTorqueClass checks for inclusion in the instance type
        range. If the class has a single instance type (i.e. no subclasses),
        then either 1) a map check is used if the class has a globally-
        defined map constant or 2) an equality check for the instance type
        is used.
      
      * Added new intrinsics to introspect class information, e.g. fetching
        instance type ranges for a class, accessing the globally-defined map
        for a class.
      
      * Removed a whole pile of existing explicit Cast<> operators that are
        no longer needed because of the implicitly generated Cast<> macros.
      
      * Added tests for the new Cast<> implementations.

      [torque] avoid ambiguity if a catch catches from other handlers · 7e7b24eb
      Tobias Tebbi authored
      Torque desugars try-catch/label constructs with several handlers
      into nested try structures, with the first handler ending-up
      innermost. So currently, if you write
      
      try {
      ...
      } label Foo {
        Throw(...);
      } catch (e) {
      
      }
      
      The catch will catch the preceding Throw in another handler.
      This is different from how multiple try-catch handlers are done in
      languages like Java, where throwing from a preceding catch handler
      is not caught by a later one. To avoid this possible ambiguity, this
      CL prohibits this pattern, enforcing that a catch handler comes first,
      before any other label-handler attached to the same try.
      This way, a catch handler never catches from any other handler on the
      same try, since they have to come later.

      [torque] add const references and disallow const class field writes · d7e02ea4
      Tobias Tebbi authored
      - Allow type expression for abstract type supertypes.
        For consistency, and ease of implementation, also allow this for enums.
      - Allow subtyping of structs. This requires changing all places where we
        checked for struct types and instead check if we have a subtype of a
        struct type.
      - This allows defining two subtypes of the Reference<T> struct for
        mutable and constant references. Mutable references are a subtype of
        constant references.
      - &T desugars to MutableReference<T>
        const &T desugars to ConstReference<T>
      - A const field of a class produces a constant reference.
        A const field of a mutable reference to a struct is const.
        A mutable field of a const reference to a struct is const.
      - It is possible to assign a new struct value to a mutable reference to
        a struct, even if the struct contains const fields. This is analogous
        to allowing assignments of let-bound structs with constant fields.
      
      Not in this CL:
      - A notion of const slices.
      - Applying const to appropriate class fields.

      [torque] multiple arrays in one object · 59e8d45a
      Tobias Tebbi authored
      This allows the definition of classes with several arrays and ports
      SmallOrderedHashTable subclasses to Torque as an example, including
      the existing CSA allocation functions for them.
      
      Overview of changes:
      - Introduce ResidueClass to encapsulate the modulo-arithmetic
        necessary to do alignment checks.
      - Add MachineOperatorReducer to the CSA pipeline to address now
        missing CSA ad-hoc constant folding that got blocked by a
        temporary phi.
      - Allow assignments to references to structs. This is needed to
        initialize the data_table part of SmallOrderedHashMap.
      - Make the NumberLiteralExpression AST-node store a double instead
        of a string. This is necessary to detect arrays with constant size
        used for padding.
      - Turn offsets into base::Optional<size_t> to ensure we don't use
        an invalid or statically unknown offset.
      - Remove CreateFieldReferenceInstruction since it doesn't work for
        complex offset computations and the logic can be expressed better
        in ImplementationVisitor.
      - Validate alignment of structs embedded in classes.

      [torque] Enum language feature · fdc9fade
      Nico Hartmann authored
      This CL implements enums in Torque in three steps:
      
      1.) It implements necessary changes to Torque's type system. In
      particular, the constraints on constexpr types are relaxed such that
      constexpr types can exist without a corresponding non-constexpr
      version. Furthermore, constexpr and their non-constexpr counterpart
      need not be of the same kind of type. This allows an AbstractType to
      have a UnionType as its non-constexpr counterpart.
      
      2.) The enum feature itself is realized as a pure desugaring in the
      parser, where all required types, constants and macro specializations
      (like FromConstexpr<>) are generated from a simple enum declaration,
      such that enum entries are not just constants, but are namespace
      scoped and have distinct types so that they can be used within
      typeswitch constructs.
      
      3.) Almost all of the existing constants defined in torque
      (.tq files) are ported to new enum definitions.

      [torque] allow allocation of strings · 8ed9be48
      Tobias Tebbi authored
      This CL generalizes and improves how we handle allocations in Torque.
      
      Overview of the changes:
      - Remove obsolete special handling for JSObject classes, since it was
        incomplete: It breaks as soon as slack tracking is active.
      - Handle array initialization using slices.
      - Properly align allocation sizes. This enabled allocating strings.
      - Port AllocateSeq{One,Two}ByteString to Torque, which is much easier
        now than the old CSA code since allocation size alignment and
        large-object space allocation just happen out-of-the-box.
      - Remove obsolete or unnecessary intrinsics, some of them turn into
        macros in the torque_internal namespace.
      - Distinguish between header size and overall size for ClassType,
        make size optional and only defined when it is statically known.

      [torque] Generate more detailed errors when instantiating generics · 332290e4
      Seth Brenith authored
      Currently it's pretty easy to write Torque code that generates an error
      in some common generic function such as Convert<To: type, From: type>,
      and unless your change is very small, it can be hard to figure out what
      part of it caused that macro specialization. This CL updates the Torque
      compiler to emit some extra information about the stack of code
      positions that caused a specialization of a macro or builtin, similar to
      what Clang does for C++ templates. Obviously there might be multiple
      places that require a particular specialization, but we only report the
      first one that caused the specialization to be created.

      [torque] Strict verification of weak fields · 72d440d9
      Seth Brenith authored
      Now that we can represent specific weak types with Weak<T>, this CL
      updates the generated verifier functions so that they permit weak
      references only to the specified type. As an example, consider the
      verifier emitted for the following field in PrototypeInfo:
      
        object_create_map: Weak<Map>|Undefined;
      
      We used to emit the following, which allowed any weak reference:
      
        CHECK(object_create_map__value.IsWeakOrCleared()
            || object_create_map__value.GetHeapObjectOrSmi().IsOddball());
      
      With this change, we emit a stricter check:
      
        CHECK(object_create_map__value.IsCleared()
            || (!object_create_map__value.IsWeak()
                && object_create_map__value.GetHeapObjectOrSmi().IsOddball())
            || (object_create_map__value.IsWeak()
                && object_create_map__value.GetHeapObjectOrSmi().IsMap()));

      [torque] introduce generic abstract types · 5bba6680
      Tobias Tebbi authored
      This expands the existing mechanism for generic structs to also cover
      abstract types. This involves:
      - Moving the SpecializationKey from StructType to Type, so that it's
        also available to AbstractType.
      - Moving the generic parameters out of the StructDeclaration AST node
        and using the existing GenericDeclaration AST node for generic structs
        and abstract types too.
      - The GenericStructType declarable gets generalized to GenericType.
      
      This will be useful for defining a Weak<T> type for weak pointers.

      [torque] Add lint errors for unused variable and label bindings · 0e53739c
      Simon Zünd authored
      This CL adds lint errors when 'let' bindings, arguments and labels
      are not used. Note that errors for 'const' bindings will be added
      later.
      
      In cases where arguments are actually needed to match the signature,
      the warning can be silenced by prefixing identifiers with "_". This
      might be needed for generic specializations or builtins called from
      TurboFan. Trying to use a variable or label that was marked with
      "_" results in a compilation error.
      
      Implicit arguments are not linted. They are implemented using exact
      string matching. Prefixing an implicit argument with "_" in a callee
      would break all callers as the names would no longer match.
      
      Drive-by: Fix all new lint errors in the existing Torque code.

      [torque] More flexibel and uniform error reporting · bdfd1e4b
      Simon Zünd authored
      This CL changes the existing TorqueError struct into a more general
      TorqueMessage by adding a "kind" enum. The contextual for lint errors
      is removed and replaced by a list of TorqueMessages.
      
      A MessageBuilder is introduced to help with the different
      combinations of present information and method of reporting. A lint
      error with custom SourcePosition can be reported like this:
      
      Lint("naming convention error").Position(<src_pos_var>);
      
      While a fatal error, with CurrentSourcePosition can be thrown
      like this:
      
      Error("something went horrible wrong").Throw();
      
      This approach is both backwards compatible and should prove flexible
      enough to add more information to messages or add other message kinds.
