/* 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, ECOFF_64,
|
|
ECOFF_SIGNED_32 or ECOFF_SIGNED_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. */
