[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.

[stack-traces] Simplify and speedup stack trace collection. Following up on https://crrev.com/c/2689185, this CL significantly simplifies the whole implementation of the stack trace capturing. Before this CL, capturing any stack trace (for the purpose of the API or Error.stack) would roughly work like this: 1. The CaptureStackTrace() function uses the StackFrameIterator to walk the system stack. For each native frame it uses the FrameSummary abstraction to get all (including potentially inlined) frames. For each of those it appends a record consisting of six elements to a FrameArray (this holds pointers to the actual closures and receivers). 2. Afterwards the FrameArray is shrinked to the required size, and a new FixedArray is allocated, and initialized with new StackTraceFrame objects where each holds a reference to the FrameArray, the index of the frame, and an initially uninitialized StackFrameInfo reference. This new FixedArray is then returned from CaptureStackTrace() and either stored on a message object or provided to the API as v8::StackTrace. The new approach removes a lot of the machinery in between and directly creates a FixedArray of StackFrameInfo objects in CaptureStackTrace(). These StackFrameInfo objects are directly exposed as v8::StackFrame on the public API, and they hold the six fields that were previously stored flat in the FrameArray. This not only avoids a lot of copying around of data and creation of temporary objects and handles, but most importantly unifies and simplifies the stack frame function inside StackFrameInfo, so you no longer need to wonder which function / object might be responsible for a certain API. There's still a lot of room for improvement. In particular we currently don't cache the source position for a given StackFrameInfo (or globally), but rather recompute it every time. This is still very fast, significantly faster than the previous approach. There are some notable (potentially user visible) changes: - The CallSite#GetPosition() method now consistently returns the Wasm module relative bytecode offset for all Wasm frames (previously it'd return the function relative bytecode offset for non-asm.js Wasm frames). - The column and line numbers returned from StackFrameInfo methods are consistently 1-based now, instead of sometimes being 0-based (Wasm) and sometimes being 1-based (JS and asm.js Wasm). The only potentially noticable difference is that for CallSite#GetLineNumber() no longer returns 0 for Wasm frames, but that was wrong and useless anyways. - CallSite#GetThis() would sometimes return the_hole, another bug flushed out by this CL. The CL also contains some other not noteworthy drive-by-cleanups.

Reland "[wasm-gc] Remove abstract rtts" This is a reland of b77deeca4bd65b006a3a6c7344c2bbabd4514122 Changes compared to original: Add explicit narrowing casts in tests for MSVC. Original change's description: > [wasm-gc] Remove abstract rtts > > In the latest wasm-gc spec, rtts of abstract types are no longer > allowed. Consequently, canonical rtts of concrete types always have > a depth of 0. > > Changes: > - Change the immediate argument of rtts to a type index over a heap > type. Abstract it with TypeIndexImmediate in function body decoding. > This affects: > value_type.h, read_value_type(), decoding of relevant opcodes, > wasm subtyping, WasmInitExpr, consume_init_expr(), and > wasm-module-builder.cc. > - In function-body-decoder-impl.h, update rtt.canon to always produce > an rtt of depth 0. > - Pass a unit32_t type index over a HeapType to all rtt-related > utilities. > - Remove infrastructure for abstract-type rtts from the wasm compilers, > setup-heap-internal.cc, roots.h, and module-instantiate.cc. > - Remove ObjectReferenceKnowledge::rtt_is_i31. Remove related branches > from ref.test, ref.cast and br_on_cast implementations in the wasm > compilers. > - Remove unused 'parent' field from WasmTypeInfo. > - Make the parent argument optional in NewWasmTypeInfo, CreateStructMap, > and CreateArrayMap. > - Use more convenient arguments in IsHeapSubtypeOf. > - Update tests. > > Bug: v8:7748 > Change-Id: Ib45efe0741e6558c9b291fc8b4a75ae303146bdc > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2642248 > Commit-Queue: Manos Koukoutos <manoskouk@chromium.org> > Reviewed-by: Ulan Degenbaev <ulan@chromium.org> > Reviewed-by: Jakob Kummerow <jkummerow@chromium.org> > Cr-Commit-Position: refs/heads/master@{#72321} Bug: v8:7748 Change-Id: I22b204b486fd185077cd6c7f15d492f5143f48fe Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2650207 Commit-Queue: Manos Koukoutos <manoskouk@chromium.org> Reviewed-by: Jakob Kummerow <jkummerow@chromium.org> Reviewed-by: Ulan Degenbaev <ulan@chromium.org> Cr-Commit-Position: refs/heads/master@{#72355}

Revert "[ic] Add a new MegaDOM IC" This reverts commit c83c9590baf677665b0872ca68cba2c1cf3524c1. Reason for revert: Speculatively reverting for a failure on Arm GC stress bot - https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Arm%20GC%20Stress/b8851256837192083520/overview Original change's description: > [ic] Add a new MegaDOM IC > > This patch implements the MegaDOM IC setup and access. A new MegaDOM > IC state indicates that we've seen only DOM accessors at this access > site. > > This CL only adds support for DOM getters in LoadIC, other kinds of > access will be added in follow on CLs. > > Still remaining TODO before shipping: > 1. Have a mechanism to invalidate the protector > 2. Have a mechanism to find the accessors that aren't overloaded > 3. Use a new builtin to miss to runtime on access check failure > > Change-Id: Ie12efe5e9fa284f023043b996d61e7d74e710ee2 > Bug: v8:11321 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2618239 > Reviewed-by: Omer Katz <omerkatz@chromium.org> > Reviewed-by: Camillo Bruni <cbruni@chromium.org> > Reviewed-by: Dan Elphick <delphick@chromium.org> > Reviewed-by: Mythri Alle <mythria@chromium.org> > Commit-Queue: Sathya Gunasekaran <gsathya@chromium.org> > Cr-Commit-Position: refs/heads/master@{#73733} Bug: v8:11321 Change-Id: Ib6a55796f2a3c345d4923f9eaa215a6ff55ed15b No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2794437 Auto-Submit: Maya Lekova <mslekova@chromium.org> Commit-Queue: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Cr-Commit-Position: refs/heads/master@{#73734}
