The following code emits "non constant" but conceptually should emit "constant". The type of __func__
is "static const char *" so either fold_builtin_constant_p needs to be relaxed a bit or fname_decl should
be building STRING_CST.
int main(int argc, char **argv)
{
puts (__builtin_constant_p(__func__) ? "constant" : "non constant");
}
