--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-14 branch has been updated by Richard Biener <rgue...@gcc.gnu.org>: https://gcc.gnu.org/g:98dc0471d5409701ae700cd7aba8716fdc500401 commit r14-10677-g98dc0471d5409701ae700cd7aba8716fdc500401 Author: Richard Biener <rguent...@suse.de> Date: Thu Jul 18 13:35:33 2024 +0200 middle-end/115641 - invalid address construction fold_truth_andor_1 via make_bit_field_ref builds an address of a CALL_EXPR which isn't valid GENERIC and later causes an ICE. The following simply avoids the folding for f ().a != 1 || f ().b != 2 as it is a premature optimization anyway. The alternative would have been to build a TARGET_EXPR around the call. To get this far f () has to be const as otherwise the two calls are not semantically equivalent for the optimization. PR middle-end/115641 * fold-const.cc (decode_field_reference): If the inner reference isn't something we can take the address of, fail. * gcc.dg/torture/pr115641.c: New testcase. (cherry picked from commit 3670c70c561656a19f6bff36dd229f18120af127)
