https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D223300 --- Comment #40 from Jan Beich <jbeich@FreeBSD.org> --- (In reply to Mikhail T. from comment #38) > Maybe, that's because I compiled rust itself (1.22.1) with "march=3Dnativ= e"?=20 Well, I use CPUTYPE=3Dnative myself (on -CURRENT amd64) and on head-i386 poudriere jail. Obviously, MACHINE_CPU had to be populated manually because bsd.cpu.mk is dumb (see bug 112997). > may also want to add the `-C codegen-units=3D${MAKE_JOBS_NUMBER}` to para= llelize the compilations. No, -C codegen-units pessimizes LTO which is enabled by default for release builds. ThinLTO isn't ready yet. https://internals.rust-lang.org/t/help-test-out-thinlto/6017 --=20 You are receiving this mail because: You are the assignee for the bug.=
