Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- There are other reasons why versioning is forbidden, e.g. __attribute__((target_clones ("avx", "default"))) void foo (void) { static void *p = &&lab; asm volatile ("" : "+m" (p) : : "memory"); lab:; } and __attribute__((target_clones ("avx", "default"))) int foo (int x) { __label__ lab; __attribute__((noinline)) void bar () { goto lab; } if (x == 5) bar (); x++; lab:; return x; } ICE too, even when they don't have any extra attributes. So the target clones code needs to cope with those in any case.
