Subject: [Bug rtl-optimization/110305] Incorrect optimization with -O3 -fsignaling-nans -fno-signed-zeros

--- Comment #8 from Michael Morrell <mmorrell at tachyum dot com> ---
Interesting information.  I still feel that perhaps both functions should use
the same logic to determine whether to make this transformation, but, for
example, the extra checking for the vector case done by
fold_real_zero_addition_p may not be needed in simplify_binary_operation_1
because of when the latter is used.
