--- Comment #3 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
> The problem is that some string functions are defined as inline functions
> using *_chk function variants. object_sizes pass transforms *_chk call
> into original function call in a regular case but not for CHKP wrappers.
> Thus CHKP wrappers need to be supported in object_sizes pass to make these
> tests pass on Darwin.

Now
grep memcpy chkp-stropt-1.c.097t.chkpopt
gives
__builtin___memcpy_chk.chkp (buf1_2(D), __chkp_bounds_of_buf1_7(D),
buf2_4(D), __chkp_bounds_of_buf2_8(D), len_5(D), 18446744073709551615);
What should I do for that?
