Abstract
A method of debugging a function upon function exit includes pausing program execution at the time of initializing the function, wherein the function initialization includes saving a set of registers on the stack, recording the value of the stack pointer, configuring a watchpoint register based on the recorded value, wherein the watchpoint register is configured to trap memory references of the function based on the recorded value of the stack pointer, and executing the function. Program execution will pause when it is exiting the function because of stack references made by the function epilogue to restore registers saved on the stack and the configured watchpoint registers.
