Overview

A folded address constant (ISO C 6.6): a base object plus a constant byte displacement, the form a pointer global's initializer must reduce to. base_kind is :symbol (a file-scope object named by symbol), :string (an interned string literal indexed by string_id), or :absolute (no object at all — symbol and string_id are nil and offset is the raw bit pattern, from a pointer cast of an integer constant such as "(dfree_t)-1"); offset is the byte displacement past that base for :symbol/:string (accumulated from subscripts, member accesses and pointer arithmetic), or the absolute value itself for :absolute; pointee is the type of the object presently at base+offset, so a further subscript or "+ n" knows how many bytes one step spans (and a cast overrides it without moving the address).
