Actually I think it should be:
inline void* operator new(std::size_t, void* __p) throw() {
void *p1;
__asm__ ("" : "=r"(p1): "0"(__p): "memory");
return __p;
}
Which is less pessimize.
Note the reason why you need this memory barrier is because the C++ standard
says inplacement news change the dynamic type.
