| 12 | |
---|
| 13 | run - This invokes the SPARC Instruction Simulator (SIS) on hello. |
---|
| 14 | |
---|
| 15 | gdb - This invokes gdb with the integrated SPARC Instruction |
---|
| 16 | Simulator (SIS) on hello. |

| 25 | The following is a sample session with sis: |

---|
| 27 | $ gmake run |

---|
| 43 | sis> quit |
---|
| 44 | |
---|
| 45 | Note that the user typed "go" to start the executable and "quit" to |
---|
| 46 | exit the simulator. The normal exit message is "IU in error mode (257)" |
---|
| 47 | because the program exits by generating an unhandled trap. |

| 50 | SAMPLE SESSION WITH GDB |
---|
| 51 | ======================= |
---|
| 52 | |
---|
| 53 | The following is a sample session with sis: |
---|
| 54 | |
---|
| 55 | $ gmake gdb |
---|
| 56 | /home/joel/gnat-3.10b/sparc-rtems//bin/sis-gdb hello |

| 76 | |
---|
| 77 | Program exited normally. |

| 78 | (gdb) quit |
---|
| 79 | |
---|
| 80 | Note that the user typed "run" to start the executable and "quit" to |
---|
| 81 | exit the debugger. Other gdb commands function the same as when gdb |
---|
| 82 | is used natively. |
---|
| 83 | |
---|
| 84 | The program "sis-gdb" is a script which always invokes a command file |
---|
| 85 | to initialize the simulator and load the executable into the simulator's |
---|
| 86 | memory. |
