Typically, we want a break to occur before the line we attach it to. And the breakpoint condition is attached to the binary location at debug time, not to the source line at assemble/compile time. I would expect a debugger to have a list of breakpoints, each attached to a location in the binary, which is in turn associated with a line of source code. You can modify the conditions on the breakpoints, and add and remove breakpoints, at will -- without any source modifications. So if you're considering attaching breakpoints to source, as suggested below, I think we're on different tangents.
