* config/rs6000/rs6000.opt (-mmass): New option to enable the
compiler to autovectorize mathmetical functions for power7 using
the Mathematical Acceleration Subsystem library.
* config/rs6000/rs6000.opt (-mveclibabi=mass): New option to
enable the compiler to autovectorize mathmetical functions for
power7 using the Mathematical Acceleration Subsystem library.
* config/rs6000/rs6000.c (rs6000_builtin_vectorized_libmass): New
function to handle auto vectorizing math functions that are in the
MASS library.
* config/rs6000/rs6000.c (rs6000_veclib_handler): New variable to
handle which vector math library we have.
(rs6000_override_options): Add -mveclibabi=mass support.
(rs6000_builtin_vectorized_libmass): New function to handle auto
vectorizing math functions that are in the MASS library.
(rs6000_builtin_vectorized_function): Call it.
* doc/invoke.texi (RS/6000 and PowerPC Options): Document -mmass.
* doc/invoke.texi (RS/6000 and PowerPC Options): Document
-mveclibabi=mass.
