[BUG] "Detected no AVX2 support"

[Selur]

hmm,...
I created a Hybrid.exe for testing which uses:

#include <QStringList>
#include <QString>
#include <QByteArray>

#if defined(_MSC_VER)
#include <intrin.h>
#elif defined(__GNUC__) || defined(__clang__)
#include <cpuid.h>
#endif

static void cpuid(unsigned int leaf, unsigned int subleaf,
                  unsigned int &eax, unsigned int &ebx,
                  unsigned int &ecx, unsigned int &edx)
{
#if defined(_MSC_VER)
    int regs[4];
    __cpuidex(regs, leaf, subleaf);
    eax = regs[0];
    ebx = regs[1];
    ecx = regs[2];
    edx = regs[3];
#else
    __cpuid_count(leaf, subleaf, eax, ebx, ecx, edx);
#endif
}

QStringList getCpuInfo()
{
    QStringList info;

    unsigned int eax, ebx, ecx, edx;

    // Leaf 0 : Vendor + max leaf
    cpuid(0, 0, eax, ebx, ecx, edx);

    unsigned int maxLeaf = eax;

    char vendor[13];
    memcpy(vendor + 0, &ebx, 4);
    memcpy(vendor + 4, &edx, 4);
    memcpy(vendor + 8, &ecx, 4);
    vendor[12] = 0;

    info << QString("Vendor: %1").arg(vendor);
    info << QString("Max CPUID leaf: %1").arg(maxLeaf);

    // Leaf 1 : basic features
    cpuid(1, 0, eax, ebx, ecx, edx);

    info << QString("SSE: %1").arg((edx >> 25) & 1);
    info << QString("SSE2: %1").arg((edx >> 26) & 1);
    info << QString("SSE3: %1").arg((ecx >> 0) & 1);
    info << QString("SSSE3: %1").arg((ecx >> 9) & 1);
    info << QString("SSE4.1: %1").arg((ecx >> 19) & 1);
    info << QString("SSE4.2: %1").arg((ecx >> 20) & 1);
    info << QString("AVX: %1").arg((ecx >> 28) & 1);
    info << QString("FMA: %1").arg((ecx >> 12) & 1);

    // Leaf 7 : extended features
    if (maxLeaf >= 7)
    {
        cpuid(7, 0, eax, ebx, ecx, edx);

        info << QString("AVX2: %1").arg((ebx >> 5) & 1);
        info << QString("BMI1: %1").arg((ebx >> 3) & 1);
        info << QString("BMI2: %1").arg((ebx >> 8) & 1);
        info << QString("AVX512F: %1").arg((ebx >> 16) & 1);
        info << QString("SHA: %1").arg((ebx >> 29) & 1);
    }

    // CPU brand string
    char brand[49] = {0};

    if (maxLeaf >= 0x80000004)
    {
        unsigned int data[4];

        for (int i = 0; i < 3; ++i)
        {
            cpuid(0x80000002 + i, 0, data[0], data[1], data[2], data[3]);
            memcpy(brand + i * 16, data, 16);
        }

        info << QString("Brand: %1").arg(QString::fromLatin1(brand).trimmed());
    }

    return info;
}

=> https://www.mediafire.com/file/tluc424y8...st.7z/file (simply replace the Hybrid.exe with this one)
which should output something similar to:

CPU INFO:   Vendor: AuthenticAMD   Max CPUID leaf: 13   SSE: 1   SSE2: 1   SSE3: 1   SSSE3: 1   SSE4.1: 1   SSE4.2: 1   AVX: 1   FMA: 1   AVX2: 1   BMI1: 1   BMI2: 1   AVX512F: 1   SHA: 1

inside the normal log.
What does it show for you?
