This avoids having to check both flags in two places, and prevents people from trying to enable WebAssembly in lite mode (which would currently build, but you still would not get Wasm support). The downside is that the default value shown by `gn args --list` now sais `""` instead of `true`.

Georg Neis authored
AbstractBytecodeArray was introduced in order to let the bytecode array accessor work on either a Handle<BytecodeArray> or a serialized BytecodeArrayRef. We have since implemented direct heap access for bytecode arrays, so we can now remove the abstraction again. Note that this means that as far as bytecode iteration is concerned we no longer access the bytecode array through the BytecodeArrayRef. I will remove the obsolete methods from that class in a follow-up CL. The downside is the loss of this explicit interface. The upside is simplicity and less code. We can justify the downside with the fact that the bytecode array data is immutable and thus the Ref indirection less meaningful than in other cases.

If two call instructions were generated right after each other, the source position table could get populated with two entries for the same PC (triggered by the follow-up CL: https://crrev.com/c/2697359). This CL fixes that by slightly changing the carry-over of source positions from nodes to instructions. The call node which has a source position attached generates two instructions: 18: gap () ([rax|R|tp] = v16(-); [rbx|R|t] = v17(-);) [rax|R|t] = ArchCallWasmFunction [immediate:4] #-1 [rax|R|tp] [rbx|R|t] [immediate:5] 19: gap () () ArchJmp [immediate:6] Those are then reversed, and the source position is attached to the first one (the ArchJmp). After reversing it again later, the source position will be set to the pc *after* the call instruction, which in the example happened to be just another call instruction which already had a source position, resulting in this code: [...] 0x388ee467d426 66 e875feffff call 0x388ee467d2a0 ;; wasm stub: WasmThrow 0x388ee467d42b 6b e850feffff call 0x388ee467d280 ;; wasm stub: WasmStackGuard [...] Source positions: pc offset position 6b 5 6b 0 By attaching the source position to the *last* instruction (after reversing), we ensure that it will be generated for an instruction *before* the call, or the call itself if this is the first instruction emitted for that node.

Port 8136e399 Original Commit Message: Extract code sequence into macro-assembler for reuse between Liftoff and TurboFan. Small tweaks to macro-assembler functions Pmaddwd and Pmaddubsw to move src1 to dst on SSE when src != dst. TurboFan codegen won't be affected by this since it sets the right restrictions in instruction-selector.

Optimize ia32 code sequences. This is the same sequences as x64, which have been optimized based on supported extensions. Bug: v8:11464 Change-Id: I10396a928a431cdd2de9b22bb8a395bc0adb4694 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2704897Reviewed-by:

Extract code sequence into macro-assembler for reuse between Liftoff and TurboFan. Similar to x64, there is a bit of register-aliasing checking due to the rather strict requirements for the code sequence depending on the CpuFetures that are supported.

This is a partial reland of https://crrev.com/c/v8/v8/+/2601880 . This change improves readability and helps prepare for when ScopeInfo will not be convertible to FixedArrayBase.

Now that we create a full frame for interrupts during the baseline out-of-line prologue, we shouldn't consider the out-of-line prologue builtin's frames as BASELINE, but rather have the frame above be the baseline frame.
