[...] Thanks for testing, and nice to see it helps. Both patches are in upstream elfutils git now and are also applied to the fedora rawhide elfutils package now. Cool! Thanks. I just submitted bug 754798. (BTW, I'm still debugging that library filename issue.) Is there some change on this issue?

BTW. From the systemtap README: Consider configuring with --enable-dejazilla to automatically contribute to our public test result database. That makes it easier to compare test results at https://web.elastic.org/~dejazilla/viewsummary.php Also since systemtap depends on elfutils you might need ppc64le elfutils support, which only recently has been contributed: https://lists.fedorahosted.org/pipermail/elfutils-devel/2014-July/004090.html https://lists.fedorahosted.org/pipermail/elfutils-devel/2014-July/004091.html -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

I think at least the file testsuite/systemtap.sum should list which tests exactly failed, maybe there is some common cause to most of these failures. Yes, taking a look at it, the most common failures come from the 'listing_mode' test -- 633 failures (out of 835): # grep -c '^FAIL: listing_mode' systemtap.sum 633 A nice improvement on that one might put ppc64el closer to powerpc (244 uf). I'll take a look at it. On 07/10/2014 08:08 AM, Mark Wielaard wrote: Consider configuring with --enable-dejazilla to automatically contribute to our public test result database. Sure. I'll contribute results there after making sure I'm not making (any other) big mistakes :) Also since systemtap depends on elfutils you might need ppc64le elfutils support, which only recently has been contributed: Hey, many thanks for pointing those out. It would be hard to get serious results w/out correct ABI support. :) I built an elfutils package w/ your patches. The unexpected failures decreased by 24 (from 835 to 811).

Bug#752891: systemtap: build on ppc64el
Just documenting an observations. Debugging continues tomorrow.
I'll try to find something about the listing_mode failures.
The failing tests are those which do address liblisting_mode.so by
non-absolute pathname. Only the absolute pathname work.
There are 4 modes for specifying the filename:
- liblisting_mode.so (pp_simple)
- ./liblisting_mode.so(pp_rel)
- *liblisting_mode.so (pp_wild)
- /.../liblisting_mode.so (pp_abs)
and only the absolute variant PASSes; the other 3 variants FAIL.
Steps to reproduce:
===
Absolute pathname:
--
testsuite# make check \
RUNTESTFLAGS=listing_mode.exp \
LISTING_MODE_SUBTEST='process.library(/root/git/systemtap/testsuite/liblisting_mode.so).function(libfoo)'
=== systemtap Summary ===
# of expected passes5
# of unexpected failures28
# of known failures 48
# of untested testcases 1007
passfail total: 5 + 28 = 33
Simple / Relative / Wild pathnames:
---
testsuite# make check \
RUNTESTFLAGS=listing_mode.exp \
LISTING_MODE_SUBTEST='process.library(liblisting_mode.so).function(libfoo)'
=== systemtap Summary ===
# of expected passes2
# of unexpected failures31
# of known failures 48
# of untested testcases 1007
passfail total: 2 + 31 = 33
(same summary for './lib[...]' and '\*lib[...])
Related code:
-
proc stap_list_cmd_lib {pp {exp } {nlines_exp 1} {arguments }} {
global sopath sofullpath
set pp_simple [string map sopath $sopath $pp]
stap_list_cmd $pp_simple $exp $nlines_exp $arguments

Hi Timo, [...] Btw, would it be possible for you to run the upstream testsuite on that architecture? [...] Sure. I ran the upstream test-suite on ppc64el and powerpc ports for comparison, both running on KVM guests, linux kernel 3.14 (Debian). git remote: git://sourceware.org/git/systemtap.git git commit: 035685897c43de5cdbc15b3fc38d75c6a8955bc3 # ./configure [args from Debian srcpkg + --disable-refdocs] # make -jN # make install # make check # make installcheck (following [1]) On powerpc: # make check [...] === systemtap Summary === # of expected passes1692 # of unexpected failures244 # of unexpected successes 1 # of expected failures 287 # of known failures 59 # of untested testcases 782 # of unsupported tests 9 # make installcheck [...] FAIL: all pid tests - unexpected EOF (kernel crash) On ppc64el: # make check [...] === systemtap Summary === # of expected passes1078 # of unexpected failures835 # of unexpected successes 1 # of expected failures 287 # of known failures 58 # of untested testcases 687 # of unsupported tests 9 # make installcheck [...] === systemtap Summary === # of expected passes1400 # of unexpected failures1247 # of unexpected successes 1 # of expected failures 287 # of unknown successes 1 # of known failures 60 # of untested testcases 440 # of unsupported tests 11 I currently lack some more systemtap background to be sure.. but overall 835 uf/1078 ep vs. 244 uf/1692 ep doesn't look very good.

Hi Ritesh,
You seem to have forgotten to attach the patch.
Oops.. Indeed. :-)
Here it goes.
