  21 /* NOTE: This is a header file, but it contains executable routines.
  22    This is done this way because these routines are substantially
  23    similar, but are not identical, for all ECOFF targets.
  24
  25    These are routines to swap the ECOFF symbolic information in and
  26    out.  The routines are defined statically.  You can set breakpoints
  27    on them in gdb by naming the including source file; e.g.,
  28    'coff-mips.c':ecoff_swap_hdr_in.
  29
  30    Before including this header file, one of ECOFF_32, ECOFF_64,
  31    ECOFF_SIGNED_32 or ECOFF_SIGNED_64 must be defined.  These are
  32    checked when swapping information that depends upon the target
  33    size.  This code works for 32 bit and 64 bit ECOFF, but may need to
  34    be generalized in the future.
  35
  36    Some header file which defines the external forms of these
  37    structures must also be included before including this header file.
  38    Currently this is either coff/mips.h or coff/alpha.h.
  39
  40    If the symbol TEST is defined when this file is compiled, a
  41    comparison is made to ensure that, in fact, the output is
  42    bit-for-bit the same as the input.  Of course, this symbol should
  43    only be defined when deliberately testing the code on a machine
  44    with the proper byte sex and such.  */
