http://bugzilla.suse.com/show_bug.cgi?id=920930 Bug ID: 920930 Summary: kmod test-array failure on ppc64 because qsort do not sort array Classification: openSUSE Product: openSUSE Factory Version: 201502* Hardware: PowerPC-64 OS: openSUSE 13.2 Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem Assignee: bnc-team-screening@forge.provo.novell.com Reporter: normand@linux.vnet.ibm.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- kmod test-array failure on ppc/ppc64 because qsort do not sort array https://build.opensuse.org/package/show/openSUSE:Factory:PowerPC/kmod initial reported problems === flag_fail: [ 34s] FAIL: testsuite/test-array [ 34s] FAIL: testsuite/test-depmod <= tracked by bnc#897845 === After investigation identify a simple code snippet in attached tstqsort.c that has similar behaviour as above test-array. The printf in source shows that the qsort call do not sort the array. I did the trial with a opensuse 13.2 (glibc-2.19-16.4.1.ppc64) and tumbleweed (glibc-2.21-1.1.ppc64) and the failure is the same on both. I did gdb source debug of qsort and compared the failing ppc64 case with non failing ppc64le case. The two differs by the (*cmp) __strcmp_power8 function in stdlib/msort.c that return <= 0 for BE and >0 for LE. === if ((*cmp) (b1, b2, arg) <= 0) { *(uint64_t *) tmp = *(uint64_t *) b1; b1 += sizeof (uint64_t); --n1; } else { *(uint64_t *) tmp = *(uint64_t *) b2; b2 += sizeof (uint64_t); --n2; } === I am wondering if problem could be either a missing patch in glibc for opensuse, or different options in spec between ppc64 and ppc64le. https://build.opensuse.org/package/show/openSUSE:Factory:PowerPC/glibc -- You are receiving this mail because: You are on the CC list for the bug.
