<pre>struct Foo {
void member() __restrict__ {
Foo *__restrict__ This = this;
}
};
Clang gives the diagnostic:
test.cpp:3:23: error: cannot initialize a variable of type 'Foo *restrict' with
an rvalue of type 'restrict Foo *'
Foo *__restrict__ This = this;
^ ~~~~
1 error generated.
Clang seems to think that `this` has type `restrict Foo *` (restrict on Foo,
rather than the pointer)
The GCC extension says:
<<a href="http://gcc.gnu.org/onlinedocs/gcc/Restricted-Pointers.html#Restricted-Pointers">http://gcc.gnu.org/onlinedocs/gcc/Restricted-Pointers.html#Restricted-Pointers</a>>
"Within the body of T::fn, this has the effective definition T *__restrict__
const this."</pre>
