      [turbofan] Initial support for Array constructor specialization. · aeb41de0
      bmeurer authored 
      Introduce a JSCreateArray operator that represents the Array
constructor, and lower call and construct calls to the Array
constructor to JSCreateArray. Currently we don't yet replace
that with an inline allocation, but always use the specialized
stubs for the Array constructor.

This saves a lot of unnecessary deopts and elements transitions
because now we can actually consume the allocation site feedback
for the transitions.

      [simd] Introduce SIMD types (as classes) · a60f1922
      rossberg authored 
      - Introduce a proper bit for SIMD primitive values.
- Introduce constructors for individual SIMD types. These are currently just classes, which seems good enough for now, given that we always have exactly one global map per SIMD type.

The only problem with using class types for SIMD is that a SIMD constant won't be a subtype of its specific type, only of the general SIMD type. But until we actually introduce SIMD constants into the compiler that shouldn't matter.

      SIMD.js Add the other SIMD Phase 1 types. · 7b9670b6
      bbudge authored 
      Adds Int32x4, Bool32x4, Int16x8, Bool16x8, Int8x16, Bool8x16.
Adds Simd128Value base heap object class.
Changes heap/factory construction pattern to use arrays.
Adds replaceLane functions to facilitate testing.

NOPRESUBMIT=true
(presubmit checks erroneously interpret array declaration in macro definition as variable size array.)

      Expose SIMD.Float32x4 type to Javascript. · e5ed3bee
      bbudge authored 
      This CL exposes the constructor function, defines type related
information, and implements value type semantics.
It also refactors test/mjsunit/samevalue.js to test SameValue and SameValueZero.

TEST=test/mjsunit/harmony/simd.js, test/cctest/test-simd.cc

      Revert of Steps towards unification of number bitset and range types. (patchset #4 id:60001 of https://codereview.chromium.org/837723006/)

Reason for revert:
Breaks test-types/Maybe, i.e.

out/Release/cctest --random-seed=-707413401 test-types/Maybe

started failing afterwards

Original issue's description:
> Steps towards unification of number bitset and range types.
>
> - New invariant on union types: if the union has a range then the number
>   bits in the bitset must be cleared.
>
> - Various tweaks in intersection and union to satisfy the invariant.
>
> - Exposed and used representation bits in range types (and the Limits
>   helper class).
>
> - Implemented Glb for ranges so that the Is predicate handles
>   ranges correctly.
>
> - Change typer weakening so that it does not rely on GetRange.
>   However, the code still seems to be a bit fragile.
>
> - Removed the Smi types from the type system core, instead introduced
>   Signed31, Unsigned30 and created constructors for Small(Un)Signed
>   that point to the right type for the architecture.
>
> - Punched a hole in the config to be able to get to the isolate so
>   that it is possible to allocate heap numbers for newly created
>   ranges.

  that point to the right type for the architecture.

- Punched a hole in the config to be able to get to the isolate so
  that it is possible to allocate heap numbers for newly created
  ranges.
