Description Michael Petlan 2017-03-10 14:21:23 UTC 
Description of problem:

While x86_64 seems to be OK, on ppc64, dyninst seems to be not working at all. I have just tried few simple tests for both static and dynamic instrumentation.

Version-Release number of selected component (if applicable):
dyninst-9.2.0-5.fc25.ppc64

How reproducible:
100%

Steps to Reproduce:
1. run the attached reproducer
2.
3.

Actual results:

Static instrumentation creates a segfaulting binary:
(gdb) bt full
#0  0x00003fffb690f620 in DYNINST_lock_tramp_guard () from /usr/lib64/dyninst/libdyninstAPI_RT.so.9.2
No symbol table info available.
#1  0x0000000010100168 in ?? ()
No symbol table info available.
#2  0x0000000000000000 in ?? ()
No symbol table info available.

When trying dynamic instrumentation, the mutator cannot attach the mutatee and causes its crash.

--FATAL-- #68: Dyninst was unable to attach to the specified process
--FATAL-- #68: BPatch.C[1040]: no process 15600 defined in procsByPid

[1]+  Killed                  ./mutatee


Expected results:

Both static and dynamic instrumentation works.

Additional info:

Comment 3 Josh Stone 2017-03-10 17:05:28 UTC 
Can you try 9.3.1 in rawhide?  Stan is also working on this for f25:
https://koji.fedoraproject.org/koji/buildinfo?buildID=867035
Comment 4 Stan Cox 2017-03-30 00:50:58 UTC 
ppc64 9.3.1 is fine for the dynamic case:
% ldd mutator | grep libparseAPI
 libparseAPI.so.9.3 => /usr/lib64/dyninst/libparseAPI.so.9.3 (0x00003fff89a00000)
...b
% cat RESULT.log
MUTATION OK.

There is a problem for the static case which is due to this:
 https://github.com/dyninst/dyninst/issues/355
With that patch in 9.3.1 the test worked fine:
sh run.sh
=== building the code ===
make: Nothing to be done for `all'.
=== running mutator ===
MUTATION DONE. MUTATOR IS GOING...
=== running mutated mutatee ===
MUTATION OK.

So we should probably try to get that patch into a 9.3.1-2
