--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-13 branch has been updated by Andrew Pinski <pins...@gcc.gnu.org>: https://gcc.gnu.org/g:ac96973150b3279fe157f160efd83995077c7590 commit r13-8420-gac96973150b3279fe157f160efd83995077c7590 Author: Andrew Pinski <quic_apin...@quicinc.com> Date: Sun Mar 10 22:17:09 2024 +0000 Fold: Fix up merge_truthop_with_opposite_arm for NaNs [PR95351] The problem here is that merge_truthop_with_opposite_arm would use the type of the result of the comparison rather than the operands of the comparison to figure out if we are honoring NaNs. This fixes that oversight and now we get the correct results in this case. Committed as obvious after a bootstrap/test on x86_64-linux-gnu. PR middle-end/95351 gcc/ChangeLog: * fold-const.cc (merge_truthop_with_opposite_arm): Use the type of the operands of the comparison and not the type of the comparison. gcc/testsuite/ChangeLog: * gcc.dg/float_opposite_arm-1.c: New test.
