      [x64] Compare map instead of value to heap number map in ToStringStub. · 02a2580b
      bmeurer authored 
      Fixes a typo introduced earlier, where we compare the value to heap
number map instead of the map loaded previously.

      [crankshaft] Re-add fast-case for string add left/right. · 4542a2d4
      bmeurer authored 
      Now the StringAddStub can optionally convert it's parameters to strings
(following the rules for the addition operator). This could be further
optimized once we have a ToPrimitiveStub, but it should be sufficient
for the moment.

Also removed the unused Strength parameter to the HStringAdd operator,
because string addition does not depend on language mode.

      [builtins] Add support for NewTarget to Execution::New. · 1dfac69f
      bmeurer authored 
      Introduce new builtins Construct and ConstructFunction (in line
with the Call and CallFunction builtins that we already have) as
proper bottleneck for Construct and [[Construct]] on JSFunctions.
Use these builtins to support passing NewTarget from C++ to
JavaScript land.

Long-term we want the CallConstructStub to be used for
gathering feedback on entry to construction chain (i.e. the
initial new Foo), and use the Construct builtins to do the
actual work inside the construction chain (i.e. calling into
super and stuff).

MIPS and MIPS64 ports contributed by akos.palfi@imgtec.com.

      If @@toStringTag is an accessor property, we cannot assume that the result
of calling Object.prototype.toString() for objects with the same map.

      Split the GN 'snapshot_toolchain' logic out into an include file. · 7d5d1570
      dpranke authored 
      We need to build parts of v8 with a toolchain that might be different
from both the default (target) toolchain and the regular host toolchain,
because we need the snapshot to have the same bit-width as the target.
V8's build defines a 'snapshot_toolchain' setting for this.

It turns out that we need the value of this toolchain to be exposed
to the Chromium build because some of the test targets (in browser_tests)
depend on d8 and need to be able to built using the same toolchain.

      Reland of Make profiler no frame region detection code more robust [ia86/x64] · 4962bbb1
      alph authored 
      Upon collection of the stack trace if the current PC falls into
the frame building code, the top frame might be in a non-consistent
state. That leads to some of the frames could be missing from the
stack trace.

The patch makes it check instructions under current PC and if they
look like the frame setup/destroy code, it skips the entire sample.

Support for x86/x64
