23/* NOTE: This is a header file, but it contains executable routines.
24 This is done this way because these routines are substantially
25 similar, but are not identical, for all ECOFF targets.
26
27 These are routines to swap the ECOFF symbolic information in and
28 out. The routines are defined statically. You can set breakpoints
29 on them in gdb by naming the including source file; e.g.,
30 'coff-mips.c':ecoff_swap_hdr_in.
31
23e2c83b
AC		 32 Before including this header file, one of ECOFF_32, ECOFF_64,
33 ECOFF_SIGNED_32 or ECOFF_SIGNED_64 must be defined. These are
34 checked when swapping information that depends upon the target
35 size. This code works for 32 bit and 64 bit ECOFF, but may need to
36 be generalized in the future.
252b5132
RH		 37
38 Some header file which defines the external forms of these
39 structures must also be included before including this header file.
40 Currently this is either coff/mips.h or coff/alpha.h.
41
42 If the symbol TEST is defined when this file is compiled, a
43 comparison is made to ensure that, in fact, the output is
44 bit-for-bit the same as the input. Of course, this symbol should
45 only be defined when deliberately testing the code on a machine
46 with the proper byte sex and such. */
