Return 8-byte vectors in memory instead of MMX registers. This is the
-default on Solaris@tie{}8 and 9 and VxWorks to match the ABI of the Sun
-Studio compilers until version 12. Later compiler versions (starting
-with Studio 12 Update@tie{}1) follow the ABI used by other x86 targets, which
-is the default on Solaris@tie{}10 and later. @emph{Only} use this option if
-you need to remain compatible with existing code produced by those
-previous compiler versions or older versions of GCC@.
