-dnl  The std/rep/movsl/cld is very slow for small blocks on pentium4.  Its
-dnl  startup time seems to be about 165 cycles.  It then needs 2.6 c/l.
-dnl  We therefore use an open-coded 2 c/l copying loop.
-
-dnl  Ultimately, we may want to use 64-bit movq or 128-bit movdqu in some
-dnl  nifty unrolled arrangement.  Clearly, that could reach much higher
-dnl  speeds, at least for large blocks.
