# AMD Upstreams AVX10_V2_AUX Support Into LLVM Clang 24

In addition to 

AVX10_V2_AUX adds dedicated data processing and format conversion for helping accelerate AI workloads. This adds onto AVX10 with instructions for converting standard data types to compressed data formats like FP4 and FP6, additional OCP microscaling formats, new rounding modes, and more. AVX10_V2_AUX is part of the AI Compute Extensions (ACE) worked on by both Intel and AMD as part of the x86 Ecosystem Advisory Group.

Engineers from both Intel and AMD have worked on various bits of software around the

LLVM/Clang 24.1 stable should be out around next March so we'll see what more work from the Intel/AMD x86 Ecosystem Advisory Group makes it into this next open-source compiler release.

[AMD working on AVX10_V2_AUX support for the GCC compiler](https://www.phoronix.com/news/GCC-AVX10-V2-AUX-Patches), this summer they also posted AVX10_V2_AUX support for the LLVM/Clang compiler. As of yesterday that enablement was merged for LLVM 24 for that important step toward AI Compute Extensions (ACE).

Merged to LLVM 24 Git on Monday was the initial AVX10_V2_AUX ISA support and is being exposed with the Clang compiler via the new

**-mavx10v2aux** compiler flag. The AVX10_V2_AUX implementation spans 15k lines of new code over 20 patches. See[the LLVM pull request](https://github.com/llvm/llvm-project/pull/206888)for those curious about any other details of this implementation.
