commit 08876d96b76d8ca3337c6bc64114b20446625962
Author: Michael Meissner <meissner@linux.ibm.com>
Date:   Fri Nov 17 21:47:52 2023 -0500

    Add support for vector pair built-in functions.
    
    This patch adds a series of built-in functions to allow users to write code to
    do a number of simple operations where the loop is done using the __vector_pair
    type.  The __vector_pair type is an opaque type.  These built-in functions keep
    the two 128-bit vectors within the __vector_pair together, and split the
    operation after register allocation.

+@subsection PowerPC Vector Pair Built-in Functions Available on ISA 3.1
+
+GCC provides functions to speed up processing by using the type
+@code{__vector_pair} to hold two 128-bit vectors on processors that
+support ISA 3.1 (power10).  The @code{__vector_pair} type and the
+vector pair built-in functions require the MMA instruction set
+(@option{-mmma}) to be enabled, which is on by default for
+@option{-mcpu=power10}.
+
+By default, @code{__vector_pair} types are loaded into vectors with a
+single load vector pair instruction.  The processing for the built-in
+function is done as two separate vector instructions on each of the
+two 128-bit vectors stored in the vector pair.  The
+@code{__vector_pair} type is usually stored with a single vector pair
+store instruction.
+
+The following built-in functions are independent on the type of the
+underlying vector:
