| Title | Little in manual about in-band headers |
| Status | open |
| Priority | nice |
| Assigned user | Gareth Rees |
| Organization | Ravenbrook |
| Description | The manual doesn't have much to say about in-band headers. RB says [1]: "the manual could do with some diagrams for things like in-band headers" |
| Analysis | There needs to be a section in the user guide but we don't have any example code yet that illustrates it. (There's Open Dylan, but that's not suitable as a pedagogical example.) We expect that this feature will be useful in these cases: 1. tagged pointers; 2. malloc placeholder that stores the block size in the header (I would have liked to illustrate with a "conservative collector" but can't do this because none of the pools support scanning of ambiguous references!) |
