| 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 | |
| 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. |
| 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. */ |
