| 39 | # The breakpoint is probably at the instruction where the value being | |
| 40 | # watched (myrec.x) gets updated. This is the instruction where we | |
| 41 | # expect to receive a watchpoint notification when we do the "stepi" | |
| 42 | # below. However, having the breakpoint at the same location as this | |
| 43 | # intruction can possibly interfere with our testcase, as stepping | |
| 44 | # over the breakpoint in order to get past it may incorrectly lead | |
| 45 | # to the debugger missing the watchpoint hit. This would be a bug | |
| 46 | # in GDB, but this is not the bug that we are trying to test here. | |
| 47 | # So, we remove all breakpoints first. | |
