@fanyang-mono is this still planned for .NET 7.0? If not, can you please move it to 8.0? Thanks! |

This might have been fixed by #72982. I will try it out this week. If not, will move this to .NET8 |

AdvSimd can only be enabled when both LLVM and JIT supports it on Arm64. The support for JIT hasn't landed yet. Moving this to .NET9. |

Vector.IsHardwareAcceleratedalso returnedfalse, meaning that SIMD is currently not available at all.The text was updated successfully, but these errors were encountered:
