| 43 | ff0002 INSN2 | |
| 44 | ff0003 INSN3 <-- TP2, collect $regs | |
| 45 | ff0004 INSN4 <-- TP3, while-stepping 10 collect $regs | |
| 46 | ff0005 INSN5 | |
| 47 | ||
| 48 | Notice that when instruction INSN5 is reached, the while-stepping | |
| 49 | actions of both TP1 and TP3 are still being collected, and that TP2 | |
| 50 | had been collected meanwhile. The whole range of ff0001-ff0005 | |
| 51 | should be single-stepped, due to at least TP1's while-stepping | |
| 52 | action covering the whole range. | |
| 53 | ||
| 54 | On the other hand, the same tracepoint with a while-stepping action | |
| 55 | may be hit by more than one thread simultaneously, hence we can't | |
| 56 | keep the current step count in the tracepoint itself. | |
