--- Comment #1 from Xi Ruoyao <xry111 at gcc dot gnu.org> ---
On x86_64 it's reproducible likewise:
typedef double __attribute__ ((vector_size (32))) vec;
register vec a asm("ymm2"), b asm("ymm0"), c asm("ymm1");
void
test (void)
{
for (int i = 0; i < 4; i++)
c[i] = a[i] < b[i] ? 0.1 : 0.2;
}
$ gcc/cc1 t.c -mavx2
t.c:8:10: internal compiler error: in expand_assignment, at expr.cc:6073
8 | c[i] = a[i] < b[i] ? 0.1 : 0.2;
