CodeStubs contain their corresponding Isolate* now. (part 1) · dd30db90

svenpanne@chromium.org authored Apr 24, 2014

This is a purely mechanical change, adding an Isolate* to the CodeStub
constructor and a corresponding field plus a getter. A few methods in
CodeStub and its subclasses can be simplified now, but this is done in
a separate CL.

The underlying reason apart from simplicity is that deep down in the
call chain we need to detect if the serializer is active or not. This
information will be part of the Isolate, not a global variable with
funky synchronization primitives around it (which is fundamentally
wrong and the underlying cause for race conditions and a catch-22
during initialization).

Fix C++ type of Factory::NewFixedDoubleArray. · 8c57b450

The change fixes the C++ type of Factory::NewFixedDoubleArray to
reflect the empty array case, where we return an empty
FixedArray (rather than FixedDoubleArray).
