* aout-target.h: add to vector, call generic_relax * bfd-in.h: add to vector * bfd.c: add #define for vector * bout.c: add to vector, call generic_relax * coffcode.h: add to vector, also now has coff specific relax code for the relaxable H8/300 relocs. Also clean up abs section cruft. * elf.c: call generic_relax * ieee.c: call new vector, clean up some bugs due to the creation of bfd_abs_section * libbfd.h: add bfd_generic_relax_section EXFUN * oasys.c: call generic_relax * reloc.c: implement generic_relax * seclet.c: moved much of this into coffcode.h * srec.c: call generic_relax * targets.c: define new transfer vector

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