[Bug translator/6978] New: nice to have $$parms for probe.syscall.

[srikar at linux dot vnet dot ibm dot com]

It would be nice to have $$parms for process.syscall. 
we already provide $$parms for process("path").function("func") kind of probes.

probe process.syscall {
        printf ("%s \n", $$parm)
}

$ sudo stap -v /home/srikar/scripts/a.stp -c "abc"
Pass 1: parsed user script and 45 library script(s) in 990usr/20sys/1004real ms.
semantic error: invalid target symbol for utrace probe, $syscall, $return or
$argN expected: identifier '$$parm' at /home/srikar/scripts/a.stp:2:26 while
resolving probe point process.syscall
semantic error: no probes found
Pass 2: analyzed script: 0 probe(s), 0 function(s), 0 embed(s), 0 global(s) in
10usr/0sys/16real ms.
Pass 2: analysis failed.  Try again with more '-v' (verbose) options

Another related nice-to-have feature would be having some
other synthetic $-variable ($action?  $abort) that a process.syscall
probe handler may set in order to get the utrace report_syscall
to return something other than plain UTRACE_RESUME.

Created an attachment (id=4091)
 --> (http://sourceware.org/bugzilla/attachment.cgi?id=4091&action=view)
patch and testcase to support $$parms

The $$parms can be outputted like
$ sudo stap -e 'probe process.syscall {printf("%s\n",$$parms) exit()}'
$arg1=0x3 $arg2=0xbfe69528 $arg3=0x2004 $arg4=0xbfe69528 $arg5=0xbfe6952c
$arg6=0xbfe6b548

Since there is no type information available, the parameters have to
be printed in hex format.
