[cleanup] Remove obsolete "one byte data hint" for strings. In the early days of Chrome when we used WebKit there was no support for ASCII strings on the C++ side, so we put a hint onto these two-byte strings that said "string only contains one byte data", such that internally in V8 when these were involved in string operations, we could instead create the *cheaper* one byte strings. Nowadays Blink properly supports one-byte string representations and this additional hint only comes with overhead, since we check it in quite a few places (i.e. on the hot path for string concatenation), plus we end up consuming more memory due to the additional string maps. Removing the hint also frees one bit in the InstanceType zoo for strings. This alone improves performance on the `bench-dom-serialize.js` test case by around **3%**.

[torque] Generate instance types Design doc: https://docs.google.com/document/d/1ZU6rCvF2YHBGMLujWqqaxlPsjFfjKDE9C3-EugfdlAE/edit Changes from the design doc: - Changed to use 'class' declarations rather than 'type' declarations for things that need instance types but whose layout is not known to Torque. These declarations end with a semicolon rather than having a full set of methods and fields surrounded by {}. If the class's name should not be treated as a class name in generated output (because it's actually a template, or doesn't exist at all), we use the standard 'generates' clause to declare the most appropriate C++ class. - Removed @instanceTypeName. - @highestInstanceType became @highestInstanceTypeWithinParentClassRange to indicate a semantic change: it no longer denotes the highest instance type globally, but only within the range of values for its immediate parent class. This lets us use it for Oddball, which is expected to be the highest primitive type. - Added new abstract classes JSCustomElementsObject and JSSpecialObject to help with some range checks. - Added @lowestInstanceTypeWithinParentClassRange so we can move the new classes JSCustomElementsObject and JSSpecialObject to the beginning of the JSObject range. This seems like the least-brittle way to establish ranges that also include JSProxy (and these ranges are verified with static assertions in instance-type.h). - Renamed @instanceTypeValue to @apiExposedInstanceTypeValue. - Renamed @instanceTypeFlags to @reserveBitsInInstanceType. This change introduces the new annotations and adds the ability for Torque to assign instance types that satisfy those annotations. Torque now emits two new macros: - TORQUE_ASSIGNED_INSTANCE_TYPES, which is used to define the InstanceType enumeration - TORQUE_ASSIGNED_INSTANCE_TYPE_LIST, which replaces the non-String parts of INSTANCE_TYPE_LIST The design document mentions a couple of other macro lists that could easily be replaced, but I'd like to defer those to a subsequent checkin because this one is already pretty large.

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.

[torque] Use generated instance types, part 1 This change begins making use of the fact that Torque now knows about the relationship between classes and instance types, to replace a few repetitive lists: - Instance type checkers (single and range), defined in src/objects/instance-type.h - Verification dispatch in src/diagnostics/objects-debug.cc - Printer dispatch in src/diagnostics/objects-printer.cc - Postmortem object type detection in tools/debug_helper/get-object-properties.cc Torque is updated to generate four macro lists for the instance types, representing all of the classes separated in two dimensions: classes that correspond to a single instance type versus those that have a range, and classes that are fully defined in Torque (with fields and methods inside '{}') versus those that are only declared. The latter distinction is useful because fully-defined classes are guaranteed to correspond to real C++ classes, whereas only-declared classes are not. A few other changes were required to make the lists above work: - Renamed IsFiller to IsFreeSpaceOrFiller to better reflect what it does and avoid conflicts with the new macro-generated IsFiller method. This is the part I'm most worried about: I think the new name is an improvement for clarity and consistency, but I could imagine someone typing IsFiller out of habit and introducing a bug. If we'd prefer to keep the name IsFiller, my other idea is to rename FreeSpace to VariableSizeFiller and Filler to FixedSizeFiller. - Made Tuple3 extend from Struct, not Tuple2, because IsTuple2 is expected to check for only TUPLE2_TYPE and not include TUPLE3_TYPE. - Normalized the dispatched behavior for BigIntBase and HeapNumber. - Added a few new object printers.

[cleanup] Don't inherit from Tuple2 and Tuple3 This change updates CachedTemplateObjectMap, BreakPointInfo, and BreakPoint to inherit directly from Struct rather than Tuple2 or Tuple3. It also removes Tuple3 because nothing else used Tuple3. By avoiding tuple types, we get various benefits that Torque can provide: - stricter debug verifier functions - accessors, cast functions, and printers are generated - BreakPoint and BreakPointInfo have different instance types, so you can tell them apart at runtime or in a debugger Change-Id: I9367bc08c6dea55d659fd610f9f6105fd61c907a Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1988793 Reviewed-by: Ulan Degenbaev <ulan@chromium.org> Reviewed-by: Jakob Gruber <jgruber@chromium.org> Commit-Queue: Seth Brenith <seth.brenith@microsoft.com> Cr-Commit-Position: refs/heads/master@{#65668}

[torque] Generate instance types Design doc: https://docs.google.com/document/d/1ZU6rCvF2YHBGMLujWqqaxlPsjFfjKDE9C3-EugfdlAE/edit Changes from the design doc: - Changed to use 'class' declarations rather than 'type' declarations for things that need instance types but whose layout is not known to Torque. These declarations end with a semicolon rather than having a full set of methods and fields surrounded by {}. If the class's name should not be treated as a class name in generated output (because it's actually a template, or doesn't exist at all), we use the standard 'generates' clause to declare the most appropriate C++ class. - Removed @instanceTypeName. - @highestInstanceType became @highestInstanceTypeWithinParentClassRange to indicate a semantic change: it no longer denotes the highest instance type globally, but only within the range of values for its immediate parent class. This lets us use it for Oddball, which is expected to be the highest primitive type. - Added new abstract classes JSCustomElementsObject and JSSpecialObject to help with some range checks. - Added @lowestInstanceTypeWithinParentClassRange so we can move the new classes JSCustomElementsObject and JSSpecialObject to the beginning of the JSObject range. This seems like the least-brittle way to establish ranges that also include JSProxy (and these ranges are verified with static assertions in instance-type.h). - Renamed @instanceTypeValue to @apiExposedInstanceTypeValue. - Renamed @instanceTypeFlags to @reserveBitsInInstanceType. This change introduces the new annotations and adds the ability for Torque to assign instance types that satisfy those annotations. Torque now emits two new macros: - TORQUE_ASSIGNED_INSTANCE_TYPES, which is used to define the InstanceType enumeration - TORQUE_ASSIGNED_INSTANCE_TYPE_LIST, which replaces the non-String parts of INSTANCE_TYPE_LIST The design document mentions a couple of other macro lists that could easily be replaced, but I'd like to defer those to a subsequent checkin because this one is already pretty large.

Reduce max instance type enum value. We collect instance type statistics in FatalProcessOutOfMemory into an array, which is allocated to the max instance type value. While we want to leave space to ensure new instance types do not affect constants in the API, we can be more frugal. We currently serialize 350 maps into the startup/context snapshot.

Assign CoverageInfo an instance type This allows CoverageInfo to be distinguished from other kinds of FixedArray at runtime. I also updated it to use untagged data since it only stores ints, since that seems like the generally right thing to do (even though I doubt anybody allocates enough of these to notice the reduced GC work). Related Torque changes: - Allow structs containing untagged data to be used as class fields. This requires classifying them into the tagged or untagged sections of the class layout, and checking that their alignment requirements are met when stored in a packed array. - Generate a struct containing struct field offsets, so we can ensure that the layouts defined in Torque and C++ code match. Of course it would be nice to generate a lot more (indexed accessors, synchronized accessors, GC visitors, etc.), but we can't do it all at once.

[wasm] [debug] Implement calling imported wasm functions The interpreter was not able to call imported wasm functions (hitting UNIMPLEMENTED). This CL fixes this by creating a "CWasmEntry", which is signature-specific. It has JS linkage and receives the wasm code object to call and a buffer containing all arguments (similar to the interpreter entry). It loads all arguments from the buffer and calls the given code object. The c-wasm-entry code objects are cached per instance, such that we only create them once per signature. These wasm entry stubs will also allow us to call back to compiled code from the interpreter, which we might want to do to reduce the slowdown of executing wasm for debugging.

Inline Array.prototype.forEach in TurboFan This CL contains a few pieces: - A new mechanism to create "BuiltinContinuation" checkpoints in TurboFan graphs, which--when triggered--swizzle the values in the the FrameState to be parameters to a typically TF-generated builtin that resumes execution to finish the slow-case functionality. - Continuation builtins that have special handling in the deoptimizer and their own new frame type to ensure that the values they need to begin executing can be stashed away and restored immediately before the builtin is called via a trampoline that runs when the continuation builtin's frame execution resumes. - An implementation of Array.prototype.forEach in TurboFan that can be used to inline it. The inlined forEach implementation uses the checkpoints mechanism described above to deopt in the middle of the forEach in the cases that optimization invariants are violated. There is a slightly different continuation stub for each deopt point in the forEach implementation to ensure the correct side-effects, i.e. that the deopt of the builtin isn't programmatically observable.

[cpu-profiler] Introduce NativeFrame type. The new frame type is inteneded to represent native C++ stack frames. JS code may sometimes make calls to helper native functions that do not provide any special stack layout besides the return address and frame pointer. Currently the stack iterator bails out when it sees an unknown frame. The patch allows the iterator to unwind stacks having such frames.
