--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. There's a single double typed constant in the initializer:
<constructor 0x7ffff69dd678
type <vector_type 0x7ffff69ccb28 __m512

since this is a runtime initializer we shouldn't have gimplified it to
try
{
v = *.LC0;
out = v;
}
finally
{
v = {CLOBBER(eos)};
}
we do have to reflect the current rounding mode for non-static initializer
IIRC.
