While working on the Torque compiler, I've sometimes found it difficult to understand Torque's intermediate representation and how it corresponds to the output. In this change, I propose adding a build flag that instructs Torque to emit comments describing its IR, interspersed in the generated code. This is particularly useful for seeing the stack management instructions (Peek, Poke, and DeleteRange) which don't emit any corresponding C++ code.

Docs: https://docs.google.com/document/d/13n1qaB6A-gvgWc9NDhWm-UPuOqow_Y0DNgCeTbtIotI Modify that C++ backend so that it can emit either runtime C++ or postmortem debugging code. When in postmortem debugging mode, the overall code structure would look similar with some difference: 1. Instead of passing an Isolate* everywhere, we pass a MemoryAccessor. 2. Instead of runtime class names like String, we use uintptr_t 3. When loading data from objects, instead of TaggedField<T>::load or Object::ReadField (which read from the current process), we use the MemoryAccessor and read data from the debuggee process. 4. Return values should be wrapped in the Value struct. Implement the debug accessors for complex length expressions and add test for such class (SmallOrderedHashSet).

Currently, all runtime C++ code generated for Torque macros all goes into a single .cc file and corresponding header. This is simple, but limits how we can use that generated code. For example, field accessors are generally expected to be inlinable at compilation time (not relying on LTO). This change updates the Torque compiler to output runtime C++ code into the same *-tq-inl.inc files that contain implementations of member functions for generated classes. All Torque macros transitively called from the top-level macros are included in the same file, to avoid any need for these generated files to #include each other. These macros are emitted within per-file namespaces to avoid multiple-definition build failures.

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 change adds a new code generator, which supports a subset of the instructions supported by the existing CSAGenerator, and instead of generating CSA it generates runtime C++ code. The new generator is used to generate a set of Torque macros that return slices to indexed fields. These new macros should be sufficient to eventually support Torque-generated field accessors, BodyDescriptors, verifier functions, and postmortem field inspection in debug_helper.

Summary of changes: - GC visitors no longer rely on superclass visitors, but instead visit everything themselves. This enables generating better code. - Try to match simple body descriptors to reduce the amount of generated code. - Turn SizeFor(instance) into an AllocatedSize() method. - Remove the special handling of resizable object sizes from Torque and instead overwrite AllocatedSize in classes that need special handling in C++. - Split the visitor id lists depending on whether the class has pointer fields. - Turn Torque-generated body descriptors into an .inc file to simplify includes. - Fix generated size functions to properly align the size. - Generate GC visitors (and C++ class definitions) for all string classes and FixedArray, WeakFixedArray, and WeakArrayList. - Store generated instance types in Torque class types. This is only used to determine if a type has a single instance type in this CL.

In the process: * Augment C++-generated Torque classes with SizeFor methods to calculate size of instances. * Add a new "@generateBodyDescriptor" annotation that causes Torque to generate C++ BodyDescriptors code that can be used to visit objects compatible with existing V8 mechanisms, e.g. GC * Fully automate C++ macro machinery so that adding non-extern Torque class doesn't require any C++ changes, including ensuring generation of instance types and proper boilerplate for validators and printers. * Make handling of @export a true annotation, allowing the modifier to be used on class declarations. * Add functionality such that classes with the @export annotation are available to be used from C++. Field accessors for exported classes are public and factory methods are generated to create instances of the objects from C++. * Change the Torque compiler such that Non-exported classes implicitly have the @generateBodyDescriptor annotation added and causes both verifiers and printers to be generated. * Switch non-extern Torque classes from using existing Struct-based machinery to being first-class classes that support more existing Torque class features.

This change is the first part of adding Torque support for a "bitfield struct", which represents a set of bitfields packed together into an integer value. With this change, Torque can generate the list of BitField template specializations that allow runtime code to use the bitfield values. The flags used in SharedFunctionInfo are converted to Torque to exercise this functionality. Bitfield values are not yet accessible directly from Torque code.

For this, all Torque stub-linkage builtins use TFC instead of TFS, with a custom descriptor added to interface-descriptors.h To avoid having complex logic in the generated code, the new class TorqueInterfaceDescriptor contains the logic to create a CallInterfaceDescriptor from a signature consisting of TNode types. As an example and test, this CL ports StringCharAt to Torque.

Forge (Google3) can only run 64-bit executables. As Torque runs as part of the build process, we need a 32-bit "cross-compile" mode when we target 32-bit architectures. Note that this flag won't be needed in Chromium/V8 land, since we build V8 with the same bit width as the target architecture. This CL adds a new runtime flag to torque "-m32". When enabled, the flag forces 32-bit word sizes for various pointer/word sizes. By default, the host system sizes from {src/commons/globals.h} are used.

This change begins to implement the functionality described in https://docs.google.com/document/d/1evHnb1uLlSbvHAAsmOXyc25x3uh1DjgNa8u1RHvwVhk/edit# for investigating V8 state in crash dumps. This change adds a new library, v8_debug_helper, for providing platform- agnostic assistance with postmortem debugging. This library can be used by extensions built for debuggers such as WinDbg or lldb. Its public API is described by debug-helper.h; currently the only method it exposes is GetObjectProperties, but we'd like to add more functionality over time. The API surface is restricted to plain C-style structs and pointers, so that it's easy to link from a debugger extension built with a different toolchain. This change also adds a new cctest file to exercise some basic interaction with the new library. The API function GetObjectProperties takes an object pointer (which could be compressed, or weak, or a SMI), and returns a string description of the object and a list of properties the object contains. For now, the list of properties is entirely based on Torque object definitions, but we expect to add custom properties in future updates so that it can be easier to make sense of complex data structures such as dictionaries. GetObjectProperties does several things that are intended to generate somewhat useful results even in cases where memory may be corrupt or unavailable: - The caller may optionally provide a type string which will be used if the memory for the object's Map is inaccessible. - All object pointers are compared against the list of known objects generated by mkgrokdump. The caller may optionally provide the pointers for the first pages of various heap spaces, to avoid spurious matches. If those pointers are not provided, then any matches are prefixed with "maybe" in the resulting description string, such as "maybe UndefinedValue (0x4288000341 <Oddball>)".

This CL introduces generic Torque structs. Generics are grounded early in the Torque compilation pipeline, meaning that every instantiation of a generic struct with concrete types will be turned into a distinct StructType. As an example, consider a Tuple of types T1, T2: struct Tuple<T1: type, T2: type> { const fst: T1; const snd: T2; } which can be manipulated using generic macros, such as macro Swap<T1: type, T2: type>(tuple: Tuple<T1, T2>): Tuple<T2, T1> { return Tuple<T2, T1>{fst: tuple.snd, snd: tuple.fst}; } Currently there is no type inference for struct instantiation sites, so type arguments have to be provided explicitly: const intptrAndSmi = Tuple<intptr, Smi>{fst: 1, snd: 2}; R=sigurds@chromium.org, tebbi@chromium.org Change-Id: I43111561cbe53144db473dc844a478045644ef6c Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1714868 Commit-Queue: Georg Schmid <gsps@google.com> Reviewed-by: Tobias Tebbi <tebbi@chromium.org> Reviewed-by: Sigurd Schneider <sigurds@chromium.org> Cr-Commit-Position: refs/heads/master@{#62878}

Rework the implementation of non-external Torque classes to use Struct machinery rather than FixedArray machinery. This allows Torque-only defined 'internal' classes to the automatically generate class verifiers and printers. As part of this change, generate C++ boilerplate accessors for internal Torque classes, since this is a pre-requisite for the verifiers, printers and other Struct-based functionality. Moreover, augment the header-generating functionality in Torque to create separate header files for field offset definitions, internal class C++ definitions and instance types.

This CL introduces an 'import' statement. It does not produce any AST node. The AST contextual directly collects what source id imports what other source id. Currently the import map is unused. In the future, import syntax will be used to implement partial compilation.

Instead of generating one CodeStubAssembler-like class per namespace, Torque-generated macros are now free-standing functions not included from CSA code, and explicitly exported macros become part of the new TorqueGeneratedExportedMacrosAssembler, which CodeStubAssembler inherits from, thus making them available to all CSA code. Structs are now defined in a new header csa-types-tq.h as free-standing types with the prefix "TorqueStruct". This is a preparation for generating per Torque-file instead of per namespace.

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.

The language server and unit tests pass in an empty output directory to signal that no C++ files should be generated. As these generation steps include some validations, they should also be included in language server and unit test compilation runs. This CL introduces a "dry run" flag on the ImplementationVisitor. Additionaly, the implementation visitor wraps the file writing functionality. In case of a dry-run, file writing becomes a no-op.

This CL adds support for all kinds of Types to "textDocument/symbol" requests. While LSP has support for classes and structs, it does not have support for generic types. Only classes are marked as such, while all other types are marked as structs in terms of the LSP. Special care has to be taken with TypeAliases. Generic call sites introduce a new scope (similar to namespace scopes), where new TypeAliases are created for Generic type arguments. These TypeAliases then point to the specialized type inside this call-site specific scope. To omit the specialized TypeAliaes from the symbols list, they are marked using the "is_user_defined" flag.

The language server needs Torque compilation artifacts like declarables for more advanced features. This CL moves the GlobalContext into the LanguageServerData class when Torque compilation finishes, to preserve all the compiler data. Additionally, all declarables are split up by source id. This makes providing all symbols of a file easier.

This change generates functions that verify the things that Torque knows about objects and their fields. We still must implement each verifier function in objects-debug.cc, but we can call into the generated code to verify that field types match their Torque definitions. If no additional verification is required, we can use the macro USE_TORQUE_VERIFIER as a shorthand for a verifier that calls the corresponding generated function. A new annotation @noVerifier can be applied to both class and field definitions, to prevent generating verification code. This allows fully customized verification for complicated cases like JSFunction::prototype_or_initial_map, which might not exist at all, and JSObject::elements, which might be a one pointer filler map. Because Factory::InitializeJSObjectFromMap fills new objects with undefined values, and many verifiers need to deal with partially- initialized objects, the generated verifiers allow undefined values on every class deriving from JSObject. In cases where stricter checks were previously performed, they are kept in objects-debug.cc.

Torque semantic analysis is now a four-stage process: 1. The TypeDeclarationVisitor introduces a TypeAlias for every TypeDeclaration* (or derived) in the Torque source, but does not process the TypeDeclaration* itself. 2. All aliases are resolved in a dependency respecting manner. This CL also changes struct member resolution to happen at this point already. Types for classes are created, but their members are not resolved to allow classes to mutually reference each other in their field types. 3. 'value' declarations (macros, etc.) are processed. 4. Members of classes are processed.

This CL changes lint errors to not be printed directly to stderr. Instead, they are collected in a list that gets surfaced via the TorqueCompilerResult. This is done so they can be presented to language server clients. This change also removes the "abort_on_lint_errors" option. API users can now decide for themselves what to do, depending on the presence of lint errors in the returned list.
