2013-01-15PR c++/55663 - constexpr function templ instantiationDodji Seketeli4-0/+95
Consider the example of the problem report 1 template <typename> 2 constexpr bool the_truth () { return true; } 3 4 template <bool> 5 struct Takes_bool { }; 6 7 template<bool B> 8 using Alias = Takes_bool<B>; 9 10 template<typename T> 11 struct test { using type = Alias<the_truth<T>()>; }; 12 13 int main () { 14 test<int> a; 15 16 return 0; 17 } that yields the error: test.cc: In substitution of ‘template<bool B> using Alias = Takes_bool<B> [with bool B = the_truth<int>()]’: test.cc:11:51: required from ‘struct test<int>’ test.cc:14:13: required from here test.cc:11:51: error: integral expression ‘the_truth<int>()’ is not constant struct test { using type = Alias<the_truth<T>()>; }; I think the issue happens in the course of instantiating test<int> at line 14, when we look into instantiating Alias<the_truth<T>()> (at line 11) (using instantiate_alias_template) with T = int. There, when we check the argument 'the_truth<int>()' to see if it actually is a constant expression, in check_instantiated_arg, we fail to recognize it constexpr-ness b/c we just look at its TREE_CONSTANT. At that point, the_truth<int> should have been folded, and it's not, because instantiate_alias_template forgets to call coerce_template_parms on its arguments.
