[Bug translator/17275] New: on s390x, buildok/memory-all-probes.stp fails


https://sourceware.org/bugzilla/show_bug.cgi?id=17275

            Bug ID: 17275
           Summary: on s390x, buildok/memory-all-probes.stp fails
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
          Assignee: systemtap at sourceware dot org
          Reporter: dsmith at redhat dot com
              Host: s390x

RHEL7 s390x has utrace (tracepoint-based), but no uprobes:

====
# stap -wp4 ../src/testsuite/buildok/memory-all-probes.stp 
user-space process-tracking facilities not available [man
error::process-tracking]
Pass 4: compilation failed.  [man error::pass4]
====

RHEL5 ia64 has utrace (in-kernel), but no uprobes:

====
# stap -wp4 ../src/testsuite/buildok/memory-all-probes.stp
/home/dsmith/.systemtap/cache/02/stap_0239fcbe16622df8c2eeb7deb70d3958_27536.ko
====

Here's the contents of memory-all-probes.stp:

====
#! stap -wp4                                                                    

// Tests if all probes in memory.stp are resolvable.                            

probe vm.*,                                                                     
      vm.*.* {}                                                                 
====

All the other memory.stp build tests pass on s390x:

Somehow the translator things memory-all-probes.stp has a user-probe in it,
even though it doesn't.
