src: ignore GCC -Wcast-function-type for v8.h
This commit suggests that cast-function-type warnings be ignored from v8.h. Currently, GCC reports a number of warnings like this:
In file included from ../src/util.h:27,
from ../src/aliased_buffer.h:7,
from ../src/memory_tracker.h:5,
from ../src/base_object.h:27,
from ../src/async_wrap.h:27,
from ../src/req_wrap.h:6,
from ../src/req_wrap-inl.h:6,
from ../src/connect_wrap.h:6,
from ../src/connect_wrap.cc:1:
../deps/v8/include/v8.h: In instantiation of
‘void v8::PersistentBase<T>::SetWeak(
P*,
typename v8::WeakCallbackInfo<P>::Callback, v8::WeakCallbackType)
[with
P = node::BaseObject;
T = v8::Object;
typename v8::WeakCallbackInfo<P>::Callback =
void (*)(const v8::WeakCallbackInfo<node::BaseObject>&)]’:
../src/base_object-inl.h:123:42: required from here
../deps/v8/include/v8.h:10374:16: warning:
cast between incompatible function types from
‘v8::WeakCallbackInfo<node::BaseObject>::Callback’
{aka ‘void (*)(const v8::WeakCallbackInfo<node::BaseObject>&)’} to
‘Callback’
{aka ‘void (*)(const v8::WeakCallbackInfo<void>&)’}
[-Wcast-function-type]
reinterpret_cast<Callback>(callback), type);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The motivation for doing this that it makes it difficult to spot other warnings that might be important. Since it is v8 that performs this cast I was not able to find a way around it.
