Hand coded vector instructions

Hi, I'm an SGI novice.  We have a silicon graphics power series computer
here , and I'm wondering if there is an equivalent to machine-level
blaz for these animals .  An example would be :

ddot(a,b,c,n)

takes the vectores a,b and multipies them elemetn by element to
produce c.  The fortran version of this would be :

	subroutine ddot(a,b,c,n)

   	real a(n),b(n),c(n)

   	do 10 i = 1,n
      	   c(i) = a(i)*b(i)
10 	continue

	return 
	end


This would of course be optimized for the particular machine in
question.

So does anyone know about it.


Also, while, I'm at it, does anyone have the setup files for
gnu emacs figured out for the tar version maintained from the
free software foundation ?
Peace on Earth.
