)
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
SThe Sema object used for type-checking.
LocThe location where the implicit copy/move is being generated.
TThe type of the expressions being copied/moved. Both expressions must have this type.
ToThe expression we are copying/moving to.
FromThe expression we are copying/moving from.
CopyingBaseSubobjectWhether we're copying/moving a base subobject. Otherwise, it's a non-static member subobject.
CopyingWhether we're copying or moving.
DepthInternal 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.

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.
