Hello,

DTrace seems to no longer work properly on stable/10; I get errors like
the following

dtrace: invalid probe specifier pid$target::malloc:entry{ }:
"/usr/lib/dtrace/io.d", line 49: cannot find type: struct devstat*: Type
information is in parent and unavailable

and I know of a couple other users running into the same problem.

I recall that some changes to libdwarf, libelf and the CTF tools were needed
in order to work with clang 3.4; do you know if there's any plan to MFC them
soon as well?

Thanks,
-Mark
