Instruction execution

Pernosco provides an instruction executions view showing the stream of CPU instructions executed by each thread. This eliminates the need to single-step by showing both the control flow and the changes in register values and memory performed by each instruction. Pernosco also shows instructions that did not actually execute because they were interrupted by a synchronous signal (e.g. SIGSEGV). Naturally you can click on instructions to move around in time and click on register values to trace their dataflow. Tooltips show the full names and raw bytes of instructions, and opcode names are hyperlinks to the relevant page of the Intel manual.
