|

* Common heap header
|
|
*
|
|
* All heap objects share the same flags and refcount fields. Objects other
|
|
* than strings also need to have a single or double linked list pointers
|
|
* for insertion into the "heap allocated" list. Strings have single linked
|
|
* list pointers for string table chaining.
|
|
*
|
|
* Technically, 'h_refcount' must be wide enough to guarantee that it cannot
|
|
* wrap (otherwise objects might be freed incorrectly after wrapping). This
|
|
* means essentially that the refcount field must be as wide as data pointers.
|
|
* On 64-bit platforms this means that the refcount needs to be 64 bits even
|
|
* if an 'int' is 32 bits. This is a bit unfortunate, and compromising on
|
|
* this might be reasonable in the future.
|
|
*
|
|
* Heap header size on 32-bit platforms: 8 bytes without reference counting,
|
|
* 16 bytes with reference counting.
