It is not very clear from your posting exactly what you are trying to
do.  It sounds as though you want to add some new relocations to the
x86 target, or possibly modify some already existing ones.

The files you will most likely want to examine and edit are:

  include/elf/i386.h   -- to add new relocation numbers

  bfd/reloc.c          -- to add new BFD_RELOC_386_... enums
                          (don't forget to run 'make headers'
                          afterwards to regenerate bfd-in2.h)

  bfd/elf32-i386.c     -- to add code to process the new relocs.

  gas/config/tc-i386.c -- to add code to generate the new relocs.


Cheers
