/* NOTE: This is a header file, but it contains executable routines.
   This is done this way because these routines are substantially
   similar, but are not identical, for all ECOFF targets.
 
   These are routines to swap the ECOFF symbolic information in and
   out.  The routines are defined statically.  You can set breakpoints
   on them in gdb by naming the including source file; e.g.,
   'coff-mips.c':ecoff_swap_hdr_in.
 
   Before including this header file, one of ECOFF_32 or ECOFF_64 must
   be defined.  These are checked when swapping information that
   depends upon the target size.  This code works for 32 bit and 64
   bit ECOFF, but may need to be generalized in the future.
 
   Some header file which defines the external forms of these
   structures must also be included before including this header file.
   Currently this is either coff/mips.h or coff/alpha.h.
 
   If the symbol TEST is defined when this file is compiled, a
   comparison is made to ensure that, in fact, the output is
   bit-for-bit the same as the input.  Of course, this symbol should
   only be defined when deliberately testing the code on a machine
   with the proper byte sex and such.  */
