      Let v8's configs have an effect in 64-bit Windows Chromium builds. · 42f2261c
      thakis authored 
      The Chromium 64-bit Windows build uses "Debug_x64" and "Release_x64"
as configs for some reason, so put v8's build config settings there
too.

Reduces e.g. the runtime of CrSettingsBrowserTest.CrSettingsTest from
25s to 12s on my z840 in a 64-bit Chromium debug build
(while also turning on handle zapping).

      S390: [ic] Use the CallFunction builtin to invoke accessors. · 6c38fde9
      jyan authored 
      port 6df9a22c

Original Commit Message:
    The HandlerCompiler did not properly handle the weird edge case when a
    sloppy mode function was installed as an accessor on one of the value
    wrapper prototypes and then accessed via a load from a primitive value.
    In this case we just passed the primitive value untouched instead of
    properly wrapping it first. The CallFunction builtin properly deals with
    all the funny edge cases, so we use it instead of duplicating almost all
    of the logic here (the performance difference is neglible).

      PPC: [turbofan] Optimize loading 64-bit SMIs. · 6ae6d3f8
      mbrandy authored 
      Especially when loading and untagging SMIs within code stubs,
instances of the following pattern appear in the generated code:

    ld    <dst>, <offset>(<base>)
    sradi <dst>,<dst>,32

This CL changes that code to:

    lwa   <dst>, <SmiWordOffset(offset)>(<base>)

      Turbofan: Add MachineOperators for SIMD. · 3831d41e
      bbudge authored 
      IMPORTANT NOTE: This will likely be macroized to reduce boilerplate. Publishing now to start discussion about approach, which ops are needed, etc. Omitted functions are commented out in machine-operator.h so start there.

Takes the SIMD runtime intrinsics as a starting point for defining TF machine operators. The rationale for omitting functions is:

 - UInt constructors. int and uint aren't distinguished in wasm.
 - Check functions.
 - 'FromXxxBits' functions. These are essentially casts.
 - Simple Load / Store functions. Existing load / store with SIMD type should work.
 - Uint functions, except where their behavior is bitwise different from the Int function.

      bmeurer authored 
      This allows us to remove the troublesome %_MathClz32 intrinsic and also
allows us to utilize the functionality that is already available in
TurboFan. Also introduce a proper NumberClz32 operator so we don't need
to introduce a machine operator at the JS level.
