I use the following patch in my local mips-llvm branch:
commit 9783fdf63c8a4e1775a494b47b7f3648b65779ab

Hack around .cprestore anger

I fake the .cprestore based on what we do for _mcount in
^/sys/mips/include/profile.h. Whether this is wrong or not, I do not know, but
it results in a functional world along with the rest of my mips-llvm patches
(https://github.com/freebsd/freebsd/compare/master...kevans91:mips-llvm?expand=1),
some of which were stolen from jhb. This branch results in a functional
CLANG_BOOTSTRAP+LLD_BOOTSTRAP world and kernel for mips32, but mips64 kernel is
horribly broken in weird ways with both llvm8 and projects/clang900-import and
CLANG_BOOTSTRAP+LD_BOOTSTRAP.
