24 /* The intention is that one day, all the code which uses sections
25 will change and use seclets instead - maybe seglet would have been
28 Anyway, a seclet contains enough info to be able to describe an
29 area of output memory in one go.
31 The only description so far catered for is that of the
32 <<bfd_indirect_seclet>>, which is a select which points to a
33 <<section>> and the <<asymbols>> associated with the section, so
34 that relocation can be done when needed.
36 One day there will be more types - they will at least migrate from
37 the linker's data structures - also there could be extra stuff,
38 like a bss seclet, which descibes a lump of memory as containing
39 zeros compactly, without the horrible SEC_* flag cruft.
