This changeset makes sparc64_linux_step_trap to return 0 when a
breakpoint is set in a `ta 0x6d´ which is not a sigreturn syscall. In
these cases no rt_frame exists in the stack and thus the read PC is
wrong.
ChangeLog
2014-01-29 Jose E. Marchesi <jose.marchesi@oracle.com>
* sparc64-linux-tdep.c (sparc64_linux_step_trap): Get PC from
the sigreturn register save area only if the syscall is
sigreturn.
