--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Supposedly with the C++14 constexpr changes we need to be prepared to handle
all the ubsan builtins and internal calls we create during genericization.
Already in the still pending -fsanitize=vptr patch I had to deal with handling
the ubsan vptr type cache miss builtin even before the C++14 constexpr changes,
because that is created during static_cast handling, but if we now look at
DECL_SAVED_TREE, it can see all the builtins / internal calls in there.
I hope most of the ubsan stuff can be ignored for constexpr purposes.
