[Lldb-commits] [PATCH] D140996: [c++20] P1907R1: Support for generalized non-type template arguments of scalar type.

[Shafik Yaghmour via Phabricator via lldb-commits]

shafik added inline comments.


================
Comment at: clang/test/CodeGenCXX/template-arguments.cpp:4
+
+template<typename T> CONSTEXPR T id(T v) { return v; }
+template<auto V> auto value = id(V);
----------------
I don't see any tests covering unions or enums.


================
Comment at: clang/test/SemaTemplate/temp_arg_nontype_cxx20.cpp:12
+using F1 = Float<1.0f>;
+using F1 = Float<2.0f / 2>;
 
----------------
I believe this is IFNDR the template-heads are functionally equivelent but not equivelent: https://eel.is/c++draft/temp.class#general-3


================
Comment at: clang/test/SemaTemplate/temp_arg_nontype_cxx20.cpp:56
+using CF = ComplexFloat<1.0f + 3.0fi>;
+using CF = ComplexFloat<3.0fi + 1.0f>;
 
----------------
Can we add an enum example e.g.:

```
enum E{ E1, E2};
template <E> struct SE {};
using IPE = SE<E1>;
using IPE = SE<E2>;

```
