This bug was fixed in the package atlas - 3.10.3-8ubuntu5 --- atlas (3.10.3-8ubuntu5) eoan; urgency=medium * Enable z14 build at -march=z14, with cross-compile engine at -march=z13.

yeah, currently things are structured for one build per arch. I guess we should extend this work, and improve packaging to like enable power8/9 builds, and neon, avx2/avx512 builds, etc. I've now used: cd build-z14 && ../configure $(CONFIGURE_FLAGS) -Si archdef 2 -A IBMz14 -V 4 --cflags="$(CPPFLAGS) $(CFLAGS) -march=z14 -mzvector" -C acg gcc -F acg "$(CPPFLAGS) $(CFLAGS) -march=z14 -mzvector" -C if gfortran -F if "$(FFLAGS) -march=z14 -mzvector" -Fa xc '-march=z13' And the `-Fa xc '-march=z13'` seems to make everything work, despite long and duplicated flags everywhere. Once that lands, hopefully we will have both z13 and z14 optimized libs out of the box, finally. ** Information type changed from Private to Public ** Changed in: atlas (Ubuntu) Status: New => Fix Committed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1837577 Title: [19.10 FEAT] Provide optimized libatlas libraries for different types of z Systems ( z13+z14).
