I sent the patch for non-recursive for_each_rtx some time ago.
It didn't made big difference for i386, but I would guess on SPARC it can
be different, because of the register windows.
On Sparc actually it shows up much less.
Here, try this, build a cc1 with no optimizations enabled and "-pg",
then use it to build reload1.c with -O2, you'll see for_each_rtx
clearly in the profiles.
