C++ (Cpp) CPUGetEnabledExtensions Examples

Example #1

File: vd.cpp Project: tgoyne/VSFilter-Aegisub

CCpuID::CCpuID()
{
	VDCPUTest();

	long lEnableFlags = CPUGetEnabledExtensions();

	int flags = 0;
	flags |= !!(lEnableFlags & CPUF_SUPPORTS_MMX)			? mmx		: 0;			// STD MMX
	flags |= !!(lEnableFlags & CPUF_SUPPORTS_INTEGER_SSE)	? ssemmx	: 0;			// SSE MMX
	flags |= !!(lEnableFlags & CPUF_SUPPORTS_SSE)			? ssefpu	: 0;			// STD SSE
	flags |= !!(lEnableFlags & CPUF_SUPPORTS_SSE2)			? sse2		: 0;			// SSE2
	flags |= !!(lEnableFlags & CPUF_SUPPORTS_3DNOW)			? _3dnow	: 0;			// 3DNow

	// result
	m_flags = (flag_t)flags;
}
