The System Unit provides the Assert procedures. Code generation for
Assert can be activated through a compiler switch or command-line option:
<http://www.freepascal.org/docs-html/rtl/system/assert.html>
However, if you do leave them in, what is the overhead? In particular,
(1) does the generated code always involve a procedure call,
or is the condition check inlined, and
(2) is the (optional) message parameter (when present) always evaluated,
or only when the condition fails?
>From the generated assembler listing of a small example, I get the
impression that the check is inlined and the message parameter is
evaluated only on failure.
Can someone confirm that this is indeed always the way it is handled?
