      [wasm-relaxed-simd][x64] Prototype relaxed min and max · c3f346b7
      Ng Zhi An authored 
      Relaxed f32x4 and f64x2 min and max.

These instructions only guarantee results when the inputs are non nans,
and when the inputs are not 0s of opposite signs.

Reuse existing float binop testing harnesses and add special checks for
such constants when relaxed operations are being tested.

Drive-by rename of x64 instruction codes to be Minps/Maxps/Minpd/Maxpd
since they map down exactly to a single instruction.

      [wasm-gc] Implement array.copy (experimental) · dfdc8f68
      Manos Koukoutos authored 
      Changes:
- Add --experimental-wasm-gc-experiments flag.
- Add array.copy opcode. Implement it in decoding and code generation
  behind the new flag.
- Add WasmCodeBuilder::BoundsCheckArrayCopy. Move BoundsCheckArray to
  the private section.
- Add WasmArrayCopy and WasmArrayCopyWithChecks builtin.
- Add WasmArrayCopy runtime function.
- Add WasmArray::ElementSlot.
- Always print two hex digits in CHECK_PROTOTYPE_OPCODE.
- In test-gc, print the thrown-error message if the function should not
  throw.
- In test-gc, add GetResultObject with one argument.

      [wasm] Complete element segment features for reftypes/typed-funcref · 37579df7
      Manos Koukoutos authored 
      Main changes:
- Allow global.get in elements segments with expressions-as-elements.
- Allow element segments with types other than funcref.

Detailed changes:
- Move WasmInitExpr to its own file. Add stream opearator << support.
- Simplify type of PrintCollection.
- Make WasmElemSegment use an array of WasmInitExpr's over the previous
  ad-hoc implementation. Move null_index to WasmModuleBuilder.
- Refactor consume_element_segment_header. Make it return a
  WasmElemSegment.
- Refactor consume_element_expr. Make it return a WasmInitExpr.
- Refactor DecodeElementSection. Make it invoke
  consume_element_segment_header, then populate its element array.
- Update module-instantiate.cc to handle global.get elements.
- Fix bug in wasm-objects.cc where the wrong type index was passed into
  module()->has_signature()
- Adapt and add tests.

      [wasm-simd] Move load/store lane out of post-mvp · 848137c4
      Ng Zhi An authored 
      Define a new macro list, since this has 1 immediate operand (lane index)
compared to other SIMD load/stores.

Also remove all the ifdef guards.

      Reland "[wasm-gc] Remove abstract rtts" · d3b41d07
      Manos Koukoutos authored 
      This is a reland of b77deeca

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.
>
