<p>Exception handling for most programming languages is designed to recover from
conditions that rarely occur during general use of an application. To that end,
exception handling should not interfere with the main flow of an
application&apos;s algorithm by performing checkpointing tasks such as saving
application's algorithm by performing checkpointing tasks such as saving
the current pc or register state.</p>
<p>The Itanium ABI Exception Handling Specification defines a methodology for
providing outlying data in the form of exception tables without inlining
speculative exception handling code in the flow of an application&apos;s main
speculative exception handling code in the flow of an application's main
algorithm. Thus, the specification is said to add "zero-cost" to the normal
execution of an application.</p>
