Hello, at least since 14-release, I can't compile base/ports with CPUTYPE post nehalem. Any '-march' declaring AVX(*) capability leads to SIGILLing binaries with default -O2 CFLAGS. Not much of a help, but here's a ports example, but same result with base outcome too: zsh: illegal hardware instruction (core dumped) /var/ports-wrktree/editors/vim/work-console/vim-9.0.2143/src/vim kernel: pid 56502 (vim), jid 0, uid 0: exited on signal 4 (core dumped) gdb /var/ports-wrktree/editors/vim/work-console/vim-9.0.2143/src/vim /var/ports-wrktree/editors/vim/work-console/vim-9.0.2143/runtime/doc/vim.core GNU gdb (GDB) 13.2 [GDB v13.2 for FreeBSD] Copyright (C) 2023 Free Software Foundation, Inc.

Is CPUTYPE supposed to stay untouched these days? Thanks, -harry
