The above looks to me like a syscall that isn't hooked up.
>From syscall.S, I see
LDREGX %r20(%r19), %r19
/* If this is a sys_rt_sigreturn call, and the signal was received
* when not in_syscall, then we want to return via syscall_exit_rfi,
* not syscall_exit. Signal no. in r20, in_syscall in r25 (see
* trampoline code in signal.c).
*/
ldi __NR_rt_sigreturn,%r2
comb,= %r2,%r20,.Lrt_sigreturn
.Lin_syscall:
ldil L%syscall_exit,%r2
be 0(%sr7,%r19)
ldo R%syscall_exit(%r2),%r2
r19 and sr7 are both zero.
