/* This file was created with the aid of ``gdb-events.sh''.
|
| 26 |
|
|
|
| 27 |
|
|
The bourn shell script ``gdb-events.sh'' creates the files
|
| 28 |
|
|
``new-gdb-events.c'' and ``new-gdb-events.h and then compares
|
| 29 |
|
|
them against the existing ``gdb-events.[hc]''. Any differences
|
| 30 |
|
|
found being reported.
|
| 31 |
|
|
|
| 32 |
|
|
If editing this file, please also run gdb-events.sh and merge any
|
| 33 |
|
|
changes into that script. Conversely, when making sweeping changes
|
| 34 |
|
|
to this file, modifying gdb-events.sh and using its output may
|
| 35 |
|
|
prove easier. */
