This contributes to #93095

It covers all of the instructions in FEAT_BF16. This an optional 8.2 feature and from 8.6 is mandatory in any hardware with SVE. All the methods are binaryfloat16 versions of existing double methods in SVE/SVE2. This requires 16bit binary float support adding to C# before it can be implemented.

This list was auto generated from the C ACLE for SVE, and is in three parts:

The methods list reduced down to Vector versions. All possible varaints of T are given above the method.
The complete list of all methods. The corresponding ACLE methods and SVE instructions are given above the method.
All rejected ACLE methods. These are methods we have agreed that do not need including in C#.
Where possible, existing C# naming conventions have been matched.

Many of the C functions include predicate argument(s), of type svbool_t as the first argument. These are missing from the C# method. It is expected that the Jit will create predicates where required, or combine with uses of conditionalSelect(). For more discussion see #88140 comment.

[MichalPetryka]

I think we should open a proposal for System.BFloat16 before this is considered.

[a74nh]

I think we should open a proposal for System.BFloat16 before this is considered.

Agreed. I suspect this API is of low priority.
