// Project:     Zip CPU -- a small, lightweight, RISC CPU core
6
//
7
// Purpose:     Disassemble machine code files onto the stdout file.  Unlike
8
//              the zdump program that is part of the assembler suite, this
9
//      program takes the pfile.bin output of the bench test suite and adds
10
//      profiling information to the output.  It's useful for finding out where,
11
//      at least in simulation, your time is being spent.  It can also be used,
12
//      after the fact, to get a trace of what instructions the CPU executed.
