I tried upgrading to the debian testing version of valgrind, 1:3.13.0-2.
That doesn't complain about unknown instructions, but causes some
miscomputation. E.g.,
~/build/gmp/mini-gmp/tests/t-mul
succeeds when run normally, but running under valgrind fails like
mpz_mul failed:
a:
-ffffffffffffffffffffff00000007ffffffffffffff00000000000000fffffffffffffffffffff
b: 1fffffffffffffffffffffffffffffffffffffffe00007ffffffff
r:
-1fffffffffffffffffffffe0000000ffffffffffdfffe7ffffffff000020001ffff7ff000040fffdfff81ffff800000000e00007ffffffff00000001ffff800000001

I'd suggest to get an official valgrind release (not a Debian improved
variant) and if that too is buggy, report it to Julian et al:
