/* 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. */
