It must have had large code for all the array address calculations.

I have been thinking about un-inlining spls.  This saves 29K out of
1096K text.  It may even save some time (because function call overhead
is small better locality more than compensates for it).  I haven't found
a benchmark that shows a clear advantage either way.  I tried kernel
compiles, i/o's with a small block size, `ping -f localhost's with the
usual (small) block size, and ttcp's with small and large block sizes,
on a P5 and a 486/33.  ttcp is known to use a lot of spls.
