https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D264949 Lorenzo Salvadore <salvadore@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |antoine@FreeBSD.org --- Comment #16 from Lorenzo Salvadore <salvadore@freebsd.org> --- (In reply to Mark Millard from comment #14) Thanks Mark, those links are exactly what I was searching. I read in there that our package build servers took 8 hours to build gcc11. which is 6 hours more than what was necessary for gcc10, for which LTO_BOOTSTRAP is not available. Of course, this is only for one version (CURRENT) and for one architecture (amd64): LTO_BOOTSTRAP is default on 6 architectures and at the moment we support 3 releases. So LTO_BOOTSTRAP by default probably increases packages build time consumption by a few days (distributed on all machines building packages; I don't know how many they are). Is it really acceptable? Also, please keep in mind that everything we are discussing for gcc11 also concerns gcc11-devel, so all measurements should be multiplied by 2. Moreover, we have to think about exp-runs: is it acceptable to increase exp-runs building times by 6 hours per jail? I am unsure. I add antoine@ to= CC, so we can ask him directly. I would also like to ask some packages building servers maintainer, but I am unsure who should I ask. Unless LTO optimiziation is really significant (but I fear it is not), I wo= uld disable it by default for the sake of more efficient building machines and faster exp-runs. If there is no agreement on this, I think at least explain= ing the issue in pkg-help is necessary. --=20 You are receiving this mail because: You are the assignee for the bug.=
