[Bug testsuite/19470] New: process_by_pid.exp always fails on arches that don't support .plt probes


https://sourceware.org/bugzilla/show_bug.cgi?id=19470

            Bug ID: 19470
           Summary: process_by_pid.exp always fails on arches that don't
                    support .plt probes
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: testsuite
          Assignee: systemtap at sourceware dot org
          Reporter: dsmith at redhat dot com
  Target Milestone: ---

Currently, only x86/arm/aarch64 support .plt probes. However, the
process_by_pid.exp testcase always tries to use .plt probes, causing failures
on all other arches.

The testcase does the equivalent of the following (this is from a ppc64
system):

====
# stap -p4 ../src/testsuite/systemtap.base/process_by_pid.stp 123
semantic error: while resolving probe point: identifier 'process' at
../src/testsuite/systemtap.base/process_by_pid.stp:12:7
        source: probe process($1).function("*") {
                      ^

semantic error: no match

Pass 2: analysis failed.  [man error::pass2]
Number of similar error messages suppressed: 4.
Rerun with -v to see them.
