--- Comment #5 from Patrick Palka <ppalka at gcc dot gnu.org> ---
IIUC __builtin_is_constant_evaluated() currently acts as an optimization
barrier for the frontend's speculative folding since we don't want to
prematurely fold is_constant_evaluated() to false if the expression in question
would later be manifestly constant evaluated (in which case
is_constant_evaluated() must be folded to true). PR97553 is caused by the same
issue I think.
