[Bug translator/22087] New: implicitptr.exp failing after the bpf merge


https://sourceware.org/bugzilla/show_bug.cgi?id=22087

            Bug ID: 22087
           Summary: implicitptr.exp failing after the bpf merge
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: translator
          Assignee: systemtap at sourceware dot org
          Reporter: dsmith at redhat dot com
  Target Milestone: ---

On 3.10.0-693.el7.x86_64, when run with the pre-bpf code, the
systemtap.base/implicitptr.exp test gets 18 passes. With HEAD, the test gets 11
passes and 8 UNTESTED items, which really means that "stap -l" fails where it
didn't before.

Here's an example. Pre-bpf code:

====
PASS: implicitptr.c compile m64-O
stap -L process("implicitptr.exe").statement("foo@*:13") reports:
listified:
exe_uses_implicit_ptr caught: child process exited abnormally
UNTESTED: probe listing implicitptr-m64-O
====

HEAD:

====
PASS: implicitptr.c compile m64-O
stap -L process("implicitptr.exe").statement("foo@*:13") reports:
process("/root/rhel7-prebpf/testsuite/implicitptr.exe").statement("foo@/root/src.prebpf/testsuite/systemtap.base/implicitptr.c:13")
$j:int* $k:int** $l:int*** $i:int
PASS: probe listing implicitptr-m64-O (ijkl)
====
