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 

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 

Use appropriate @dots{} and @minus{} markup in the documentation.
