So, the big list of unknown symbols was my fault! Whoops. i've gotten further using gcc-6.4 by fixing some of the warnings/issues that have crept up. Here's a review for one of them: https://reviews.freebsd.org/D26504 However, now I've hit: /usr/local/bin/mips-unknown-freebsd13.0-ld: /usr/home/adrian/work/freebsd/head-embedded/obj/mips_ap/usr/home/adrian/work/freebsd/head-embedded/src/mips.mips/tmp/usr/lib/libc++.so.1: undefined reference to `__atomic_fetch_sub_8' /usr/local/bin/mips-unknown-freebsd13.0-ld: /usr/home/adrian/work/freebsd/head-embedded/obj/mips_ap/usr/home/adrian/work/freebsd/head-embedded/src/mips.mips/tmp/usr/lib/libc++.so.1: undefined reference to `__atomic_load_8' /usr/local/bin/mips-unknown-freebsd13.0-ld: /usr/home/adrian/work/freebsd/head-embedded/obj/mips_ap/usr/home/adrian/work/freebsd/head-embedded/src/mips.mips/tmp/usr/lib/libc++.so.1: undefined reference to `__atomic_fetch_add_8' .. looks like we need some 64 bit atomics now in mips32 for libc++ / devd. -adrian
