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:
====
# stap -p4 ../src/testsuite/buildok/memory.stp

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