Either a pointer to an AST node or the offset within the external AST source where the AST node can be found. More... | |
A lazy pointer to an AST node (of base type T) that resides within an external AST source.
The AST node is identified within the external AST source by a 63-bit offset, and can be retrieved via an operation on the external AST source itself.

Either a pointer to an AST node or the offset within the external AST source where the AST node can be found.
If the low bit is clear, a pointer to the AST node. If the low bit is set, the upper 63 bits are the offset.
