X87: [turbofan] Implemented the optional Float32RoundTiesEven operator. · 0770fcba

zhengxing.li authored Dec 04, 2015

  port 57117b83 (r32308)

  original commit message:
  The Float32RoundTiesEven operator rounds float32 numbers towards the nearest
  integer. If the distance to two integers is the same, then the result is
  the even integer. This is the default rounding mode of the ieee 754 floating
  point standard.

  I implemented the optional Float32RoundTiesEven operator on x64, ia32, arm, and arm64.

X87: [crankshaft] Deoptimize if HHasInPrototypeChainAndBranch hits a proxy. · 69ea09dd

zhengxing.li authored Dec 04, 2015

  port a330af0e (r32539)

  original commit message:
  The optimized code generated by Crankshaft cannot properly deal
  with proxies (in the prototype chain), and there's probably no
  point in trying to make that work^Wfast with Crankshaft at all.
  TurboFan will handle that properly; Crankshaft just bails out
  to fullcodegen, which then goes to the runtime, which should do
  the right thing soon.

    Whenever the InstanceOfStub finds a proxy (either passed as object or
    somewhere on the prototype chain), it should bailout to the
    %HasInPrototypeChain runtime function, which will do the right thing
    (soonish).

Preserve information about dots in numbers across parser rewriting. · 1e4681c3

bradnelson authored Dec 03, 2015

Fix several operations in the parser that rewrite constant expressions
to preserve knowledge regarding whether a value originally contained a ".".
This information is required to accurately validate Asm.js typing.

Making the assumption that if either side of a binary operation contains
a dot, that the rewritten expression should be treated as a double for
Asm.js purposes. This is a slight deviation from the spec (which
would forbid mix type operations).

[turbofan, arm64] Fix native stack parameters on arm64. · 282e9411

I added a flag to the CallDescriptor which indicates that the native
stack should be used for a CallObject instead of the js stack on arm64.

Additionally I removed the use of EmitPrepareArguments because the
current implementation does not work when float and int parameters are
mixed. I plan to fix it in a future CL, because currently I have a
problem figuring out the type of a parameter.
