Line Breakpoints
Line Breakpoint
Suspends program execution when it reaches a specific line in the source code. When a line breakpoint is set, its address is compared to the program counter during each instruction cycle. If a match occurs, the program is suspended and control is turned over to the debugger.

Line Breakpoint Activities

Some Example Uses

  • View machine state at a particular point in the program's execution
  • Determine if a line of code is ever reached
  • Determine whether some software or hardware event has occurred
  • Check program logic or calculation results
  • Inject "what if" test values into a program

A line breakpoint differs from an address breakpoint in that a line breakpoint works at the source level while an address breakpoint works at the machine level.
