A Gentoo wiki page explains that the support was only in a Cavium-provided toolchain, not upstream (https://wiki.gentoo.org/wiki/MIPS/ERLite-3). jmallett added saa/saad instructions to our base gas in r208737 (https://svnweb.freebsd.org/changeset/base/208737, see contrib/binutils/gas/config/tc-mips.c) but support is not in the FreeBSD mips binutils port. This issue should probably be addressed by adding support to the binutils port, and also adding a workaround to the base system.
