Hi Jakub,
Thank you for your suggestion. I actually learned from your earlier patch
(https://gcc.gnu.org/cgit/gcc/commit?id=7f940822) and had already planned to
update tree-call-cdce.cc when handling these builtins. Your guidance is much
appreciated!
Best regards,
Yuao

Note, not just constant folding is needed, but I think the builtins should
be handled in
tree-call-cdce.cc (can_test_argument_range, edom_only_function,
get_no_error_domain).
