Most of the libs that truly benefit from this already do runtime feature detection.
The biggest offender is probably perl, but it's easy to correct (patch the makefile), and Mozilla (this one may be a lot harder).
Problem with Mozilla, is that maybe SpiderMonkey's JIT generates SSE2?
found in Bugtracker: Bug 889714 - [yast2-core?] installation aborts before GUI starts http://bugzilla.opensuse.org/show_bug.cgi?id=889714 Bug 872908 - yast yast: line 429: 2060 Illegal instruction https://bugzilla.novell.com/show_bug.cgi?id=872908 Bug 897758 - Qt5 is compiled with SSE2 by default http://bugzilla.opensuse.org/show_bug.cgi?id=897758 only the first is not SOLVED (i didnt try a new install, but perhaps the problem is goen with Bug 872908 as ist is the same Yast-Problem, isnt it?) so any problems with Qt5 or RUBY should be solved! @ClaudioFreire: you said: perl problems could easily be solved could you please open a description in Bugzilla how to patch the makefile? (you seem to know what to do, dont you?) Mozilla should be no big Problem as Felix Miata said: "I have working Firefox on both Fedora 21/KDE 4.14.1 and on Mageia 5/KDE 4.14.1, both updated in recent hours, both running newer kernels (3.17) than 13.2 will be released with (3.16)." and both are OSS ;-) but the Jagermonkey-bug should not exist any more: https://bugzilla.mozilla.org/show_bug.cgi?id=596457 -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
