The implementation of the StreamingDecoder depends on async compilation. However, when the --single-threaded flag is set, async compilation is not available. Therefore V8 does not support streaming compilation at the moment if the --single-threaded flag is set. This CL is the first step to support streaming compilation in --single-threaded mode. This CL makes the StreamingDecoder an abstract class, and the current implementation a sub-class called AsyncStreamingDecoder. A follow-up CL will provided a second sub-class implementation for streaming compilation in --single-threaded mode.

There's no need for it to be a JSArray. In the spec it's a List which roughly corresponds to FixedArray (but not JSArray). Gotchas: - There's no good point in time where we know the array length, since resolving might be interleaved with iteration. - Using ExtractFixedArray in places where we don't need to extract, since it takes care of things like allocating the resulting array in the right space etc. Drive-by fix: Previously we pre-allocated an array 1 elements too big, but never noticed it since the last element was the hole.

The operations are implemented: - i16x8.load8x8_s - i16x8.load8x8_u - i32x4.load16x4_s - i32x4.load16x4_u - i64x2.load32x2_s - i64x2.load32x2_u on x64 and i32. The rest of the arch currently bail out, and will be implemented in subsequent patches. The liftoff-compiler.cc code looks very similar to the one for LoadMem, the only difference is special handling of kSplat v.s. kExtend. kExtend always loads 8 bytes, so the bounds check and tracing is different. Compared to LoadMem there is less need for pinning, since the result is always going to be in a SIMD/FP register, which is different from the index/addr register. The enum LoadTransformationKind was moved from function-body-decoder-impl.h to function-body-decoder.h so that no unncessary header file inclusions were needed to liftoff, and also it's a better place for it to live.

For load extends, we can use Ldr, which does not require us to manually calculate address - ld1r uses post-index, so we have to add the index ourselves. By checking the operation in the instruction-selector, we can set the addressing mode for load extends to be MRR, then use Ldr in the codegen.

This change updates some Torque-defined classes to include more precise field types where possible. It also updates those classes to use @generateCppClass. One field was removed because it's unused (PrototypeInfo::validity_cell), and two fields in StackFrameInfo actually became less precise because they're based on Script::name, which is an embedder-provided untyped Local<Value>. (Automatically generated accessors pointed out this bug easily.) This change also includes a couple of minor fixes in Torque.

The typed function references proposal allows an optional second parameter to Table.grow containing the initialization value for the newly added entries for tables that do not support null defaults. This CL adds this functionality but hides it behind a newly added experimental flag --experimental-wasm-typed-funcref.

Do not lock mutex for the full duration of the slow path of allocation on background threads. For example sweeping and allocation of a new page is now performed outside of the lock.

This is a reland of 3cc981cb with a fix for data race detected by TSan. Original change's description: > [wasm][debug] Fix tier down during streaming compilation > > If the debugger is enabled while streaming compilation is happening, we > won't correctly tier down to Liftoff. This is because during streaming > compilation, we always compile for no debugging. Fixing that is a bit > tricky, since when the debugger is enabled, functions can either already > have finished compiling, or they are currently being compiled, or their > wire bytes are not received yet. > Instead of handling this correctly while streaming compilation is > running, we just recompile the whole module with Liftoff after streaming > compilation finished. > > For testing this, we use the existing tests for async compilation, and > enable --wasm-test-streaming, which compiles via the streaming decoder > even in the async compilation case. > > R=thibaudm@chromium.org > > Bug: v8:10531 > Change-Id: I0177248a9ad2e90f83faee965d6746de05423f1f > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2207133 > Reviewed-by: Thibaud Michaud <thibaudm@chromium.org> > Commit-Queue: Clemens Backes <clemensb@chromium.org> > Cr-Commit-Position: refs/heads/master@{#67882} Bug: v8:10531, v8:10544 Change-Id: I884922b6ac55543e6ff9b1046438f6b3abab6f64 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2207187Reviewed-by:

For single-threaded, we can not tier up in the background. Hence we can either tier up in foreground (which is pointless), or not tier up. This CL disables Liftoff, so will compile TurboFan code right away.
