Hm. At least I can reproduce the problem here with my original patch on
egcs-1.1b. Looking at the code, it seems that the entries for the registers
which may be modified by a subroutine call are not set in regs_ever_live,
however, the code that does this is in the generic gcc part, so unless you
patched that, I would guess that you are using a newer gcc and it was fixed
there?

I don't have much time currently, so this may take another month or so until
I get enough time to look at this (and try it on a current gcc).
