Due to https://chromium-review.googlesource.com/c/v8/v8/+/1835541 it's now possible that we reach ProcessApiCall without any arguments hints. I don't know how to test this in d8.

Remove TaggedIsAsyncGenerator since all but one use is to generate asserts that are handled automatically by TNodes. The remaining use is then just inlined. Also removes unused IsFastJSIterResult function.

The `set disassembly-flavor` command is only available when debugging a x86 target. On other targets, sourcing `tools/gdbinit` fails as a result.

This CL changes the Tagged loads when pointer compression is enabled. It shouldn't affect anything for the time being since if we have pointer compression enabled, we are going to be storing Compressed values. Later, we will eliminate the Compressed representation and that it's where it will come into effect.

It was recently changed to Tagged in https://chromium-review.googlesource.com/c/v8/v8/+/1832174, but IntPtr is a better choice since we are doing an IntPtr equality check below. AnyTagged loads will decompress in the near future. Then, https://chromium-review.googlesource.com/c/v8/v8/+/1822637 needs this CL before submission since otherwise we will be decompressing a value that we don't need to decompress.

Since C++14, there is a spec'ed attribute for deprecation of methods, functions, types, aliases or anything else. This CL switches from the GCC __attribute__ to this standard attribute. This allows to use the V8_DEPRECATED and V8_DEPRECATE_SOON macros on anything where the standard attribute can be used (including {using} statements that were not working before). It also avoids the need to nest the whole declaration in the macro, making the code more readable.

The particular combination of (1) having callee-saved registers in the stub per the C++ calling convention, (2) passing arguments to the callee on the stack, and (3) that callee throwing an exception, caused the saved registers to be restored to bogus values. To fix this, the stack unwinder needs to compute the stub's frame size correctly (i.e. without stack parameters).

This removes the output parameter returning the number of stack slot for the frame from {LookupExceptionHandlerInTable}. This is a remnant from when V8 had dynamically sized frames (aka. full-codegen), which is no longer the case. The frame size can easily be computed independent of the exception handler found during the lookup.

Empty slow element dictionary had the sticky bit set. This bit was used to indicate that the dictionary cannot go to the fast mode either because the dictionary had elements with attributed or elements at large indices. There is no reason for the empty dictionary to have this bit set. This causes bugs in some corner cases.

Ingvar Stepanyan authored
Unfortunately, codebase contains lots of places that use one of the two formats as an internal representation for Wasm locations: 1) {line: 0, column: byte offset within entire module} 2) {line: function index, column: byte offset within function} These places choose these formats interchangeably and convert from one to another depending on the presence of source map URL in Wasm. This is not very convenient and makes it hard to add support for DWARF which should behave just like Wasm with source maps - that is, report a raw Wasm script instead of fake scripts per each disassembled function, and use representation (1) instead of (2) internally. I tried to refactor these locations and avoid checking for source map URLs in the previous CL - https://crrev.com/c/v8/v8/+/1833688. However, it quickly got out of hand, and updating code in one place just kept revealing yet another that gets broken by the changes, so I made a decision to abandon it and leave to someone who knows the codebase better. Instead, this CL is based on https://crrev.com/c/v8/v8/+/1809375, but, rather than trying to integrate DWARF separately and only for supported agents, it pretends that encountering DWARF section is the same as encountering a `sourceMappingURL` section with fake URL "wasm://dwarf". This ensures that Wasm with DWARF behaves exactly in the same way as Wasm with source maps, just like we want, with minimal changes to the codebase. The only downside is that frontends without DWARF support won't get even a disassembled version of Wasm that contains DWARF info. This is unfortunate, but, as per previous discussions, should be fine given current state of Wasm debugging.

The test creates 10000 modules, which runs in less then one second in release builds, but can take much longer with stress flags and on special bots. It timed out on the tsan isolates bot in a variant passing --stress-wasm-code-gc. Since the test should only verify that we support more than 1000 modules in a single isolate, we do not need to run it in that variant. Thus just skip it.

TracedGlobalTrait was unable to override v8::TracedGlobal<v8::Object> for avoiding the destructor because it is needed on the API surface itself and C++ ODR which prohibits specialization after template instantiation. Avoid this problem by providing a separate type TracedReference that, similar to TracedGlobal, is purely traced but avoids the destructor completely. This only works for embedders that have their memory management tied to V8 as it is prone to accessing already reclaimed objects otherwise.

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.
