Detailed Description

CXXExpansionStmtPattern - Represents an unexpanded C++ expansion statement.

There are four kinds of expansion statements.

Enumerating expansion statements.
Iterating expansion statements.
Destructuring expansion statements.
Dependent expansion statements.

An 'enumerating' expansion statement is one whose expansion-initializer is a brace-enclosed expression-list; this list is syntactically similar to an initializer list, but it isn't actually an expression in and of itself (in that it is never evaluated or emitted) and instead is just treated as a group of expressions. The expansion initializer of this is always a syntactic-form 'InitListExpr'.

Example:

///   template for (auto x : { 1, 2, 3 }) {
///     // ...
///   }
///

Note that the expression-list may also contain pack expansions, e.g. '{ 1, xs... }', in which case the expansion size is dependent.

Here, the '{ 1, 2, 3 }' is parsed as an 'InitListExpr'. This node handles storing (and pack-expanding) the individual expressions.

Sema then wraps this with a 'CXXExpansionSelectExpr', which also contains a reference to an integral NTTP that is used as the expansion index; this index is either dependent (if the expansion-size is dependent), or set to a value of I in the I-th expansion during the expansion process.

The actual expansion is done by 'BuildCXXExpansionSelectExpr()': for example, during the 2nd expansion of '{ a, b, c }', I is equal to 1, and BuildCXXExpansionSelectExpr(), when called via TreeTransform, 'instantiates' the expression '{ a, b, c }' to just 'b'.

Represents an unexpanded iterating expansion statement.

An 'iterating' expansion statement is one whose expansion-initializer is a a range, i.e. it has a corresponding 'begin()'/'end()' pair that is determined based on a number of conditions as stated in [stmt.expand] and [stmt.ranged].

Specifically, let E denote the expansion-initializer; the expansion statement is iterating if the type of E is not an array type, and either

2a. 'E.begin' and 'E.end' exist (irrespective of whether they're accessible, deleted, or even callable), or

2b. ADL for 'begin(E)' and 'end(E)' finds at least one viable function.

If neither A nor B apply to E (or if E is an array type), we treat this as a destructuring expansion statement instead (see case 3 below).

Notably, case 2a only checks whether the 'begin' and 'end' members exist and does not perform proper overload resolution; this is because if there is a begin/end function, but it for some reason is not usable (e.g. because it is non-const but E is const), then we'd rather error and tell the user that their begin/end function is wrong rather than falling back to destructuring.

Conversely, case 2b does perform overload resolution, simply because ADL may find quite a few begin/end overloads for unrelated types that happen to be in the same namespace. E.g. if the type of E is 'std::tuple', then there are quite a few begin/end pairs in the namespace 'std', but non of them can actually be used for a 'std::tuple', and we definitely want to destructure a tuple rather than error about it not being iterable.

In either case, once we've decided that the expansion statement is indeed iterating, we do make sure that the expression 'E.begin()'/'begin(E)' is well-formed, but any error at that point is a hard error and does not make us switch to destructuring instead.

The result of this expression is stored in a variable 'begin', which is then used to compute another variable 'iter' (which is just 'begin' + the expansion index) during expansion. During the N-th expansion, the expansion variable is then set to '*iter'. See [stmt.expand] for more information.

The expression used to compute the size of the expansion is not stored and is only created at the moment of expansion. See Sema::ComputeExpansionSize() for more information about this.

Example:

///   static constexpr std::string_view foo = "abcd";
///   template for (auto x : foo) {
///     // ...
///   }
///

Here, 'begin' is 'foo.begin()', and during e.g. the 0-th expansion, 'iter' is 'begin + 0', and thus '*iter' yields 'a', which results in 'x' being a variable of type 'char' with value 'a'.

Represents an unexpanded destructuring expansion statement.

A 'destructuring' expansion statement is any expansion statement that is not enumerating or iterating (i.e. destructuring is the last thing we try, and if it doesn't work, the program is ill-formed).

This essentially involves treating the expansion-initializer as the initializer of a structured-binding declaration, with the number of bindings and expansion size determined by the usual means (array size, std::tuple_size, etc.).

During the N-th expansion, the expansion variable is then initialized with the N-th binding of the structured-binding declaration. This is implemented by wrapping the initializer with a CXXExpansionSelectExpr, which selects a binding based on the current expansion index when called from TreeTransform.

Example:

///   std::tuple<int, long, unsigned> a {1, 2l, 3u};
///   template for (auto x : a) {
///     // ...
///   }
///

Here, we build 'auto [_U0, _U1, _U2] = a', and during e.g. the 0-th expansion, 'x' is initialized with '_U0'.

Represents an expansion statement whose expansion-initializer is type-dependent.

This will eventually become an iterating or destructuring expansion statement once the expansion-initializer is no longer dependent.

Dependent expansion statements can never be enumerating: even if the expansion size of an enumerating expansion statement is dependent (which is possible if the expression-list contains a pack), we still don't build an 'Enumerating' 'CXXExpansionStmtPattern' for it.

Example:

///   template <typename T>
///   void f() {
///     template for (auto x : T()) {
///       // ...
///     }
///   }
///
