      jgruber authored 
      Instead of auto-generating the Name() convenience accessor, use a macro to
avoid wasting code space.

  BUILTIN_CODE(isolate, Name)

expands to

  isolate->builtins()->builtin_handle(Builtins::kName);

This reduces the size of libv8.so by 134,752 bytes on a x64 release build.

      [generators] remove SuspendFlags enum and related code · 53553f5d
      Caitlin Potter authored 
      SuspendFlags was originally used by the suspend operation to determine
which field to record the bytecode offset of a suspended generator, and
the value the generator was resumed with. For async generators, await
operations would use a separate field, in order to preserve the previous
yield input value. This was important to ensure `function.sent`
continued to function correctly.

As function.sent is being retired, this allows the removal of support
for that. Given that this was the only real need for SuspendFlags in the
first place (with other uses tacked on as a hack), this involves several
other changes as well:

- Modification of MacroAssembler AssertGeneratorObject. No longer
  accepts a SuspendFlags parameter to determine which type of check to
  perform.
- Removal of `flags` operand from SuspendGenerator bytecode, and the
  GeneratorStore js-operator.
- Removal of `flags` parameter from ResumeGeneratorTrampoline builtins.
- Removal of Runtime functions, interpreter intrinsics and
  AccessBuilders associated with the [[await_input_or_debug_pos]] field
  in JSAsyncGeneratorObject, as this field no longer exists.
- Addition of a new `Yield` AST node (subclass of Suspend) in order to
  prevent the need for the other SuspendFlag values.

      [arm64] Clear the upper 32 bits after a TruncateDoubleToI · 124ff532
      Andreas Haas authored 
      TruncateDoubleToI generated a 32-bit result but did not clear the upper
32 bits. This violated the invariant that the upper 32 bits should be
cleared when the result is 32 bits. This change fixes the bug mentioned
below. Clearing the upper 32 bits is also done on x64.

      Don't dereference handles in (macro-)assembler functions used by TF. · 9b3174b2
      Georg Neis authored 
      Remove all IsHeapObject/IsSmi checks from assembler and also from
the macro-assembler functions that Turbofan code generation uses.

Note for porters: In case it's unclear which macro-assembler
functions need to be modified, it may be best to wait until I
split MacroAssembler in a followup-CL, which will make that clear.

      [arm] Introduce UseScratchRegisterScope · 8e84b715
      Pierre Langlois authored 
      Introduce a stripped down version of UseScratchRegisterScope for ARM and use it
inside the assembler and macro-assembler. At the exception of the Call
instructions, we now use this scope instead of using the ip register
directly. This is inspired from how the ARM64 backend works.

In general, the benefit of doing this is we can catch cases where ip is being
used both by the caller and by the assembler. But more specifically, TurboFan
reserves r9 as an extra scratch register because ip can already be used by the
assembler. With this utility, we can isolate the cases in the code generator
which need an extra register and potentially fix them, allowing us to give r9
back to the register allocator.

This patch uncovered places in the assembler where we were using ip
unconditionally when we could have re-used the destination register instead.

      [elements] Rename FAST elements kinds · 26c00f4a
      Mathias Bynens authored 
      The `FAST_` prefix doesn’t make much sense — they’re all just different cases
with their own optimizations. Packedness being implicit (e.g. `FAST_ELEMENTS`
vs. `FAST_HOLEY_ELEMENTS`) is not ideal, either.

This patch renames the FAST elements kinds as follows:

- e.g. FAST_ELEMENTS => PACKED_ELEMENTS
- e.g. FAST_HOLEY_ELEMENTS => HOLEY_ELEMENTS

The following exceptions are left intact, for lack of a better name:

- FAST_SLOPPY_ARGUMENTS_ELEMENTS
- SLOW_SLOPPY_ARGUMENTS_ELEMENTS
- FAST_STRING_WRAPPER_ELEMENTS
- SLOW_STRING_WRAPPER_ELEMENTS

This makes it easier to reason about elements kinds, and less confusing to
explain how they’re used.
