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). cu Michael -- Michael Schwingen, Ahornstrasse 36, 52074 Aachen ------ Want more information?
