Abstract
Embodiments presented herein describe techniques to track and correct indirect function calls in disassembled object code. Assembly language source code is generated from a binary executable object. The assembly language source code may include indirect function calls. Memory addresses associated with the function calls are identified. A central processing unit (CPU) interrupt instruction is inserted in the disassembled source code at each indirect function call. The disassembled source code is executed. When the interrupt at each indirect function call is triggered, the function name of a function referenced by a register may be determined.
