That is, this code will do wrong being compiled with VS2008?
int cpuInfo[4];
__cpuid(cpuInfo, 1);
bool osUsesXSAVE_XRSTORE = cpuInfo[2] & (1 << 27) || false ;
bool cpuAVXSuport = cpuInfo[2] & (1 << 28) || false ;
if (osUsesXSAVE_XRSTORE && cpuAVXSuport)
{
// Check if the OS will save the YMM registers
unsigned long long xcrFeatureMask =
_xgetbv(_XCR_XFEATURE_ENABLED_MASK);
avxSupported = (xcrFeatureMask & 0x6) || false ;
}
__cpuid() will not report correctly?
