Most likely it's latent, asm constexpr just reuses the existing constexpr
machinery.
5271 static tree
5272 initialized_type (tree t)
5273 {
5274 if (TYPE_P (t))
5275 return t;
5276 tree type = TREE_TYPE (t);
5277 if (TREE_CODE (t) == CALL_EXPR)
5278 {
(rr)
5279 /* A constructor call has void type, so we need to look deeper.
*/
5280 tree fn = get_function_named_in_call (t);
5281 if (fn && TREE_CODE (fn) == FUNCTION_DECL
5282 && DECL_CXX_CONSTRUCTOR_P (fn))
5283 type = DECL_CONTEXT (fn);
5284 }
5285 else if (TREE_CODE (t) == COMPOUND_EXPR)
5286 return initialized_type (TREE_OPERAND (t, 1));
5287 else if (TREE_CODE (t) == AGGR_INIT_EXPR)
5288 type = TREE_TYPE (AGGR_INIT_EXPR_SLOT (t));
(rr)
5289 return cv_unqualified (type);
5290 }
but t is an unexpected scope_ref with no type which is not handled:
