Unless it's part of the defined interface that the user may not have
macros called "vector_size", "aligned", "a", "b" and "c", you should use
the __*__ attribute names, and __a etc. parameter names, to be
namespace-clean.
You shouldn't need to declare __builtin_* functions anyway. And if a
function can be represented directly with GNU C vector extensions, it's
preferred to implement it that way inline in the header rather than having
built-in functions duplicating existing GNU C functionality. (Look at
what AArch64 arm_neon.h does where possible, and what ARM arm_neon.h has
been moved towards lately. I don't now what the msa.h functions do, so I
don't know if this actually applies to any of them - but it's something to
consider, so that built-in functions are only defined where actually
needed.)
Use appropriate @dots{} and @minus{} markup in the documentation.
