static

Builds a statement that copies/moves the given entity from From to To.

This routine is used to copy/move the members of a class with an implicitly-declared copy/move assignment operator. When the entities being copied are arrays, this routine builds for loops to copy them.

Parameters

S	The Sema object used for type-checking.
Loc	The location where the implicit copy/move is being generated.
T	The type of the expressions being copied/moved. Both expressions must have this type.
To	The expression we are copying/moving to.
From	The expression we are copying/moving from.
CopyingBaseSubobject	Whether we're copying/moving a base subobject. Otherwise, it's a non-static member subobject.
Copying	Whether we're copying or moving.
Depth	Internal parameter recording the depth of the recursion.

Returns

A statement or a loop that copies the expressions, or StmtResult(0) if a memcpy should be used instead.

Check that the given field is initialized within a constexpr constructor.

Parameters

Dcl	The constexpr constructor being checked.
Field	The field being checked. This may be a member of an anonymous struct or union nested within the class being checked.
Inits	All declarations, including anonymous struct/union members and indirect members, for which any initialization was provided.
Diagnosed	Whether we've emitted the error message yet. Used to attach multiple notes for different members to the same error.
Kind	Whether we're diagnosing a constructor as written or determining whether the formal requirements are satisfied.

Returns

false if we're checking for validity and the constructor does not satisfy the requirements on a constexpr constructor.

Perform lookup for a special member of the specified kind, and determine whether it is trivial.

If the triviality can be determined without the lookup, skip it. This is intended for use when determining whether a special member of a containing object is trivial, and thus does not ever perform overload resolution for default constructors.

If Selected is not NULL, *Selected will be filled in with the member that was most likely to be intended to be trivial, if any.

If ForCall is true, look at CXXRecord::HasTrivialSpecialMembersForCall to determine whether the special member is trivial.
