Hello all,


This patch fixes stepping over system call instruction on architectures 
that use software single stepping and also may increment PC upon return 
from the system call to communicate error. (e.g. this is what we do on 
Neutrino).

Note: I could only test this on Neutrino.


Thanks,

Aleksandar


ChangeLog:

       * gdbarch.sh (syscall_pc_increment): New function.
       * gdbarch.h, gdbarch.c: Regenerated.
       * arm-tdep.c (arm_software_single_step): Use
       gdbarch_syscall_pc_increment and if provided, insert second
       single step breakpoint at the incremented address.
