23/* This file contains routines used to swap COFF data. It is a header
24 file because the details of swapping depend on the details of the
25 structures used by each COFF implementation. This is included by
26 coffcode.h, as well as by the ECOFF backend.
27
28 Any file which uses this must first include "coff/internal.h" and
29 "coff/CPU.h". The functions will then be correct for that CPU. */
