I've pushed a branch w/ the -freorder-blocks-algorithm=stc workaround to: git://git.launchpad.net/~dannf/ubuntu/+source/edk2 reorder-blocks It also includes some other build system fixes/cleanups. I propose we push that to sid & sync to zesty, then cherry pick just the first patch for a yakkety SRU. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1632875 Title: qemu-efi built w/ gcc-6 doesn't boot in KVM mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/edk2/+bug/1632875/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1632875] Re: qemu-efi built w/ gcc-6 doesn't boot in KVM mode
Turns out that a qemu-efi built by gcc master works in KVM mode. So I did some GCC bisecting to try and identify A) What change after GCC 6.2 made it start working again and B) What change occurred between GCC 5 and 6.2 that broke it to begin with. A) What change after GCC 6.2 made it start working again? master started working again after: # first boots commit: [c76c65ae09761b460a9c015112ca03f34aab25ff] 2016-10-13 Richard Biener I don't understand this change enough to know why it would have any effect, and it wasn't trivial enough for me to backport it to gcc-6 to test it on it's own. B) What change occurred between GCC 5 and 6.2 that broke it to begin with? The breakage started with: # first bad commit: [e57ef194b2cbbc8f178bdb6259e3bf3d2d4512e3] bb-reorder: Add -freorder-blocks-algorithm= and wire it up Based on that, I tried rebuilding qemu-efi with both -fno-reorder-blocks and -freorder-blocks-algorithm=stc. Both worked - so perhaps one of them is a better option than reverting to gcc-5. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1632875 Title: qemu-efi built w/ gcc-6 doesn't boot in KVM mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/edk2/+bug/1632875/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

We actually still do use the GCC49 profile, and that works with gcc-4.9 and gcc-5, but not with gcc-6. I'm planning on bisecting gcc to try and understand why. Indeed, the GCC5 profile with gcc-5 does lead to a early crash in UEFI, and that goes away if I drop the lto optimizations. -dann > -- > You received this bug notification because you are subscribed to the bug > report. > https://bugs.launchpad.net/bugs/1632875 > > Title: > qemu-efi built w/ gcc-6 doesn't boot in KVM mode > > To manage notifications about this bug go to: > https://bugs.launchpad.net/ubuntu/+source/edk2/+bug/1632875/+subscriptions > > Launchpad-Notification-Type: bug > Launchpad-Bug: distribution=ubuntu; sourcepackage=edk2; component=universe; status=Confirmed; importance=High; assignee=None; > Launchpad-Bug: distribution=ubuntu; distroseries=yakkety; sourcepackage=edk2; component=universe; status=Confirmed; importance=High; assignee=None; > Launchpad-Bug-Tags: patch > Launchpad-Bug-Information-Type: Public > Launchpad-Bug-Private: no > Launchpad-Bug-Security-Vulnerability: no > Launchpad-Bug-Commenters: ard-biesheuvel dannf > Launchpad-Bug-Reporter: dann frazier (dannf) > Launchpad-Bug-Modifier: Ard Biesheuvel (ard-biesheuvel) > Launchpad-Message-Rationale: Subscriber > Launchpad-Message-For: dannf -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1632875 Title: qemu-efi built w/ gcc-6 doesn't boot in KVM mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/edk2/+bug/1632875/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
