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.
