--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is what I get on the trunk:
t.c: In function ‘main’:
t.c:26:11: error: this operation requires the SVE ISA extension
26 | if (__builtin_bcmp (&freq, a, 10))
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
t.c:26:11: note: you can enable SVE using the command-line option ‘-march’, or
by using the ‘target’ attribute or pragma
during RTL pass: expand
t.c:26:11: internal compiler error: Segmentation fault
