https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D261977 --- Comment #45 from Piotr Kubaj <pkubaj@FreeBSD.org> --- (In reply to Matthias Andree from comment #44) 1. I assume it's to build GCC in a way that is as safe as possible, so that= the bootstrapped compiler will work fine. When you combine that with LTO and us using clang to build, it's definitely much safer than plain building. 2. LTO is used only for stage 2 and stage 3 (you can see that in config/bootstrap-lto-noplugin.mk). IMO that is reasonable, since using LTOi= zed GCC from stage 2 in stage 3 lets us make sure that the compiler works fine. (In reply to Robert Clausecker from comment #43) OK, I will disable bootstrap there according to your instructions. Regarding riscv64, we currently don't support GCC there. Regarding your earlier question for a capable ARM hardware, I'd consider getting something like https://www.ipi.wiki/products/ampere-altra-developer-platform. --=20 You are receiving this mail because: You are on the CC list for the bug.=
