Example 21 with AMD64

use of jdk.vm.ci.amd64.AMD64 in project graal by oracle.

the class AMD64ArrayCompareToOp method supportsAVX512VLBW.

    AMD64 arch = (AMD64) target.arch;
    EnumSet<CPUFeature> features = arch.getFeatures();
    return features.contains(CPUFeature.AVX512BW) && features.contains(CPUFeature.AVX512VL);
}

Example 22 with AMD64

use of jdk.vm.ci.amd64.AMD64 in project graal by oracle.
