* Fri Sep 28 2018 Severin Gehwolf <sgehwolf@redhat.com> - 1:11.0.ea.28-9
- Rework changes from 1:11.0.ea.22-6. RHBZ#1632174 supercedes
RHBZ-1624122.
- Add patch, JDK-8210416-RHBZ-1632174-fdlibm-opt-fix.patch, so as to
optimize compilation of fdlibm library.
- Add patch, JDK-8210425-RHBZ-1632174-sharedRuntimeTrig-opt-fix.patch, so
as to optimize compilation of sharedRuntime{Trig,Trans}.cpp
- Add patch, JDK-8210647-RHBZ-1632174-libsaproc-opt-fix.patch, so as to
optimize compilation of libsaproc (extra c flags won't override
optimization).
- Add patch, JDK-8210761-RHBZ-1632174-libjsig-opt-fix.patch, so as to
optimize compilation of libjsig.
- Add patch, JDK-8210703-RHBZ-1632174-vmStructs-opt-fix.patch, so as to
optimize compilation of vmStructs.cpp (part of libjvm.so).
- Reinstate filtering of opt flags coming from redhat-rpm-config.
* Thu Sep 27 2018 Jiri Vanek <jvanek@redhat.com> - 1:11.0.ea.28-8
- removed version less provides
- javadocdir moved to arched dir as it is no longer noarch
