Summary: This patch introduces command-line support for the Armv8.6-a architecture and assembly support for BFloat16. Details can be found https://community.arm.com/developer/ip-products/processors/b/processors-ip-blog/posts/arm-architecture-developments-armv8-6-a in addition to the GCC patch for the 8..6-a CLI: https://gcc.gnu.org/legacy-ml/gcc-patches/2019-11/msg02647.html In detail this patch - march options for armv8.6-a - BFloat16 assembly This is part of a patch series, starting with command-line and Bfloat16 assembly support. The subsequent patches will upstream intrinsics support for BFloat16, followed by Matrix Multiplication and the remaining Virtualization features of the armv8.6-a architecture.
