Abstract
The disclosure is directed to a method of loading a breakpoint enabled page of a computer program into a computer readable memory. The method includes identifying a page of a computer program to be loaded into the computer readable memory and reading a breakpoint table to identify a set of breakpoints having memory addresses located within the page of the computer program prior to loading the page of the computer program. Each breakpoint has an instruction address and an instruction storage location. For each of the set of breakpoints, the method includes reading an operating instruction of the page of the computer program located at the instruction address, storing a copy of the operating instruction at the instruction storage location within the breakpoint table, and loading a trap instruction at the instruction address to replace the operating instruction in the page of the computer program to create a breakpoint enabled page of the computer program.
