PR c++/55311 - Cannot specialize alias template with arg of type array of char
Consider this test case:
1 template <const char *const C, typename T>
2 struct A
3 {};
4
5 struct B {};
6
7 extern constexpr char HELLO_WORLD[] = "hello world";
8
9 A<HELLO_WORLD, B> g; // <-- This works fine
10
11 template <typename T>
12 using PartiallySpecialized = A<HELLO_WORLD, T>; // <-- This fails
13
At line 12 G++ fails to instantiate the alias template that has a
string variable initialized with a string literal, with the error
message:
test.cc:12:46: error: ‘"hello world"’ is not a valid template argument of type ‘const char*’ because ‘"hello world"’ is not a variable
using PartiallySpecialized = A<HELLO_WORLD, T>; // <-- This fails
^
Note that instantiating the template A at line 9 with the same
arguments as in the problematic case above works.
This happens in the context of lookup_template_class_1, when it handles
the alias template instantiation A<HELLO_WORLD, T> and thus passes the
VAR_DECL for HELLO_WORLD to convert_nontype_argument.
Note that from there decay_conversion replaces the the VAR_DECL with
its STRING_CST initializer[1]. Latter on, convert_nontype_argument
checks that the HELLO_WORLD constant it received as argument was
indeed a VAR_DECL:
else
{
tree decl;
decl = ((TREE_CODE (expr) == ADDR_EXPR)
? TREE_OPERAND (expr, 0) : expr);
if (TREE_CODE (decl) != VAR_DECL)
{
error ("%qE is not a valid template argument of type %qT "
"because %qE is not a variable",
expr, type, decl);
return NULL_TREE;
}
But the issue is, that VAR_DECL has been replaced by STRING_CST, so
the last 'if' above fails.
The fix is to teach decay_conversion to return the address of array,
rather than returning its initializer.

PR c++/52343 - error with alias template as template template argument
In the example accompanying this patch, check_instantiated_arg tries
to ensure that a non-type template argument should be a constant if it
has integral or enumeration type.
The problem is that an alias template which type-id is, e.g, an
integer, looks like an argument that has integral/enumeration type:
its TREE_TYPE is an integer type. So check_instantiated_arg
mistenkaly barks that this integral non-type argument is not a
constant.
