| Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. In computer
science, self-modifying code is code that alters its own instructions
while it is executing - usually to reduce the instruction path length
and improve performance or simply to reduce otherwise repetitively
similar code, thus simplifying maintenance. Self modification is an
alternative to the method of 'flag setting' and conditional program
branching, used primarily to reduce the number of times a condition
needs to be tested for. The method is frequently used for conditionally
invoking test/debugging code without requiring additional overhead for
every input/output cycle and also in just-in-time (JIT) compilers. |
