Yes, that is exactly what should fix the tests. Unfortunately I don't have access to darwin machine right now. Can you please test if the patch (attached) fixes the tests?
gcc/
* multiple_target.c (create_dispatcher_calls): Add target check
on ifunc.
(create_target_clone): Change assembler name for versioned declarations.
gcc/testsuite
* gcc.dg/mvc1.c: Add dg-require-ifunc condition.
* gcc.dg/mvc4.c: Ditto.
* gcc.dg/mvc5.c: Ditto.
* g++.dg/ext/mvc1.C: Ditto.
* g++.dg/ext/mvc4.C: Ditto.
* gcc.dg/mvc7.c: Add dg-require-ifunc condition and checks on resolver.
Thanks,
Evgeny
