/* Three Bit Tags
|
||||
|
||||
* 000 -- a non-immediate value. Points into the pair heap.
|
||||
*
|
||||
* 001 -- a gloc (i.e., a resolved global variable in a CAR in a code graph)
|
||||
* or the CAR of an object handle (i.e., the tagged pointer to the
|
||||
* vtable part of a user-defined object).
|
||||
*
|
||||
* If X has this tag, the value at CDAR(X - 1) distinguishes
|
||||
* glocs from object handles. The distinction only needs
|
||||
* to be made in a few places. Only a few parts of the code know
|
||||
* about glocs. In most cases, when a value in the CAR of a pair
|
||||
* has the tag 001, it means that the pair is an object handle.
|
||||
*
|
||||
* 010 -- the tag for immediate, exact integers.
|
||||
*
|
||||
* 011 -- in the CAR of a pair, this tag indicates that the pair is a closure.
|
||||
* The remaining bits of the CAR are a pointer into the pair heap
|
||||
* to the code graph for the closure.
|
||||
*
|
||||
* 1xy -- an extension tag which means that there is a five or six bit
|
||||
* tag to the left of the low three bits. See the nice diagrams
|
||||
* in ../doc/code.doc if you want to know what the bits mean.
