Match

Detect any matching elements, setting the condition flags

Compares each active 8-bit or 16-bit character left with all of the characters in the corresponding 128-bit segment of right. Where the first source element detects any matching characters in the second segment it places true in the corresponding element of the destination predicate, otherwise false. Inactive elements in the destination predicate register are set to zero.

NoMatch

The opposite of Match()

This contributes to #93095

It covers instructions in FEAT_SVE2 related to bitwise operations. They are similar to the SVE mask methods.

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.
