You can add __attribute__((sseregparm)) to function declaration. This
will force arguments to/from function to SSE registers. The problem
is, that it will result in "warning: 'sseregparm' attribute ignored",
but this can be ignored using dg-prune-output dg directive. Please see
many examples in the testsuite.
