Hi all,
when I try to compile my project I receive the error below about Core.
What does it mean?

Regards,
Matteo

Error:

C:\upp\uppsrc\Core\Mt.cpp (635): error: '_mm_pause' was not declared in this scope
 (): _mm_pause();
C:\upp\uppsrc\Core\Mt.cpp (635): note: suggested alternative: '_mm_free'
 (): _mm_pause();
 (): _mm_free

Core\Mt.cpp

void SpinLock::Wait()
{
	volatile int n = 0;
	while(locked) {
	#ifdef CPU_X86
		_mm_pause();         <<<<<<< ROW 635
	#endif
		if(n++ > 500)
			Sleep(0);
	}
}
