1 | /* This module is part of BFD */ |

| 4 | /* The intention is that one day, all the code which uses sections | |
| 5 | will change and use seclets instead - maybe seglet would have been | |
| 6 | a better name.. | |
| 7 | ||
| 8 | Anyway, a seclet contains enough info to be able to describe an | |
| 9 | area of output memory in one go. | |
| 10 | ||
| 11 | The only description so far catered for is that of the | |
| 12 | <<bfd_indirect_seclet>>, which is a select which points to a | |
| 13 | <<section>> and the <<asymbols>> associated with the section, so | |
| 14 | that relocation can be done when needed. | |
| 15 | ||
| 16 | One day there will be more types - they will at least migrate from | |
| 17 | the linker's data structures - also there could be extra stuff, | |
| 18 | like a bss seclet, which descibes a lump of memory as containing | |
| 19 | zeros compactly, without the horrible SEC_* flag cruft. | |
