Several of the probes in the signal tapset don't resolve to the kernel source.
Confirmed with 2.6.35 and 2.6.32
e.g.
probe signal.send {
if (sig == 7)
printf("sending SIGBUS to %s\n", pid_name)
}
probe signal.handle {
if (sig == 7)
printf("SIGBUS %s, code %x handler %x\n", execname(),
sig_code, @cast(ka_addr, "struct sigaction")->sa_handler)
}
gives
semantic error: failed to retrieve location attribute for local 'info'
(dieoffset: 0x7bec1): identifier '$info' at
/pkg/systemtap-1.3/share/systemtap/tapset/signal.stp:610:16
source: sig_code = $info->si_code
^
semantic error: failed to retrieve location attribute for local 'ka' (dieoffset:
0x7bebc): identifier '$ka' at :611:15
source: ka_addr = $ka

Pass 2: analysis failed. Try again with another '--vp 01' option.
