Abstract
A computer program measures the execution of machine code instructions in an executing program. A copy of the measured program is made and selected machine instructions are replaced by interrupt-causing breakpoint instructions. As each breakpoint instruction is executed, the breakpoint is replaced by the actual instruction, and a bit map is updated to indicate execution of the measured instruction. Execution resumes with the actual instruction.
