A method for evaluating a breakpoint in a line of source code includes encountering the breakpoint and evaluating whether the breakpoint is at the start of the line. If the breakpoint is at the start of the line, then the debugger stops at the breakpoint and tracks the breakpoint. If the breakpoint is not at the start of the line, then the debugger evaluates whether the breakpoint is reached via a back branch. If the breakpoint is not at the start of the line and is reached via a back branch, then the debugger stops at the breakpoint and tracks the breakpoint. If the breakpoint is not at the start of the line and is not a back branch target, then the debugger passes the breakpoint and tracks the breakpoint.

Evaluation of statement-level breakpoints

A method for implementing a step over operation by a debugger for an instruction in a routine includes receiving a step over command for an instruction and determining whether the instruction is a branch used for a function call. If the instruction is not a branch used for a function call, then the debugger treats the instruction as not a function call. If the instruction is a branch used for a function call, then the debugger determines whether the instruction is generated from source code. If the instruction is not generated from source code, then the debugger treats the instruction as not a function call. If the instruction is generated from source code, then the debugger treats the instruction as a function call.
