Public bug reported: Within glibc (2.19 on Ubuntu, but also on 2.17), some "long double" routines for PPC64 are wrong: both .c and .S files exist, and .S files are taken first though they are old and wrong. The bugs appear for some cases (for ceill(), second double is wrong). The fix is easy: remove the wrong .S files so that the correct .c files are used for building libm.so (/lib/powerpc64le-linux-gnu/libm-2.19.so).
The impacted routines are: ceill, roundl, etc. The patches have already been integrated into glibc at sourceware.org : Assuming GLIBC 2.19, you need these patches: https://sourceware.org/git/?p=glibc.git;a=commit;h=374f7f61214967bb4e2257695aeeeecc2a77f369 https://sourceware.org/git/?p=glibc.git;a=commit;h=98fb27a373f37554232e0060eef1a5bb00a07eb0 https://sourceware.org/git/?p=glibc.git;a=commit;h=c7de50250367167d8c9f35594b264f6a0af8dd0c Regards, Tony ** Affects: pcre3 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1294588 Title: glibc: some long double math routines for PPC64 are wrong: patches To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pcre3/+bug/1294588/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
