# watched (myrec.x) gets updated. This is the instruction where we
|
|
# expect to receive a watchpoint notification when we do the "stepi"
|

# below. However, having the breakpoint at the same location as this
|
|
# intruction can possibly interfere with our testcase, as stepping
|
|
# over the breakpoint in order to get past it may incorrectly lead
|
|
# to the debugger missing the watchpoint hit. This would be a bug
|
|
# in GDB, but this is not the bug that we are trying to test here.
|
|
# So, we remove all breakpoints first.
