--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I am going to fix this testcase.
The warning is expected, the code does check at runtime not to invoke
__atomic_compare_exchange_n with invalid orderings.
/* The success memory ordering must be at least as strong as \
the failure memory ordering. */ \
if (model_s < model_f) \
return 0; \
/* Ignore invalid memory orderings. */ \
if (model_f == __ATOMIC_RELEASE || model_f == __ATOMIC_ACQ_REL) \
return 0; \
I am trying to decide I just want to add -Wno-invalid-memory-model or add the
dg-warning . I am leaning towards adding the flag.
