--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The vector builder calls operand_equal_p, which in turn does:
case REAL_CST:
if (real_identical (&TREE_REAL_CST (arg0), &TREE_REAL_CST (arg1)))
return true;
if (!HONOR_SIGNED_ZEROS (arg0))
{
/* If we do not distinguish between signed and unsigned zero,
consider them equal. */
if (real_zerop (arg0) && real_zerop (arg1))
return true;
}
return false;
So, what could be done is temporarily enable flag_signed_zeros in the vector
builder.
