re:z14 - That would not sufice, as it means that it would not be part of regular archive rebuilds, autopkgtest testing of itself, reverse dependencies, and like toolchain/kernel. I am sure we can ship it, but the stability and quality concerns will be degraded a lot. And it means it will be out of scope for canonical to maintain / fix. I'm sure we will drop z14 builds if they start failing to build or are reported as broken, given lack of our z14 access on the launchpad internal infrastructure.
about flags. I'll check if -mzvector can be added, and if that helps. Can that go for all three builds? z12, z13, z14? Note that during configure stage (as seen in debian/rules) we do override cflags, flags with distro defaults. For z12 build we use: cd build && ../configure --prefix="/home/ubuntu/atlas/debian/tmp" --incdir="/home/ubuntu/atlas/debian/tmp/usr/include/s390x-linux-gnu/" --libdir="/home/ubuntu/atlas/debian/tmp/usr/lib/s390x-linux-gnu/" --shared -D c -DWALL -Ss f77lib "-L/usr/lib/gcc/s390x-linux-gnu/8/ -lgfortran -lgcc_s -lpthread" -Ss pmake 'make' -v 2 -b 64 -A IBMz12 -V 1 -t 0 --cc="cc" --cflags="-Wdate-time -D_FORTIFY_SOURCE=2 -g -O2 -fdebug-prefix-map=/home/ubuntu/atlas=. -fstack-protector-strong" -C acg gcc -F acg "-Wdate-time -D_FORTIFY_SOURCE=2 -g -O2 -fdebug-prefix-map=/home/ubuntu/atlas=. -fstack-protector-strong" -C if gfortran -F if "-g -O2 -fdebug-prefix-map=/home/ubuntu/atlas=. -fstack-protector-strong" -Ss ADdir ../../debian/archdefs/s390x --cripple-atlas-performance z13 adds -A IBMz13 -V 8 config options, and -march=z13 to all the *flags z14 adds -A IBMz14 -V 4 config options, and -march=z14 to all the *flags and no -mzvector is not used at the moment. When I attemped the build, the build stage does compile temporary binaries, and does try to execute them. Let me try to get z13 build going, and i'll provide you the logs about the failing to build z14-on-z13. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1814796 Title: [19.04 FEAT] Provide optimized libatlas libraries for different types of z Systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1814796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
