There are around 710 tests for amd64 and around 650 tests for i386. When =
everything is compiled with GCC then I get a bit less than 20 failures =
on amd64. The figure goes up to about 60 failures for i386 and building =
everything with clang. I=E2=80=99m still working through the i386 and =
clang related issues.
I=E2=80=99m tracking issues on GitHub as they are analysed.

There=E2=80=99s a fairly large number of syscalls that predate FreeBSD =
10 and are not implemented. Here are the ones added in FreeBSD 10 or =
later that aren=E2=80=99t implemented.
