Breakpoint conditions

Breakpoints have two conditions:

• The normal condition, which is specified using the command cond <breakpoint> <expr> (or by setting the Cond field when amending a breakpoint via the API), is any expression which evaluates to true or false.
• The hitcount condition, which is specified cond <breakpoint> -hitcount <operator> <number> (or by setting the HitCond field when amending a breakpoint via the API), is a constraint on the number of times the breakpoint has been hit.

When a breakpoint location is encountered during the execution of the program, the debugger will:

• Evaluate the normal condition
• Stop if there is an error while evaluating the normal condition
• If the normal condition evaluates to true the hit count is incremented
• Evaluate the hitcount condition
• If the hitcount condition is also satisfied stop the execution at the breakpoint
