ImplementSuffix is a pass for the <a href="SXML">SXML</a> <a href="IntermediateLanguage">IntermediateLanguage</a>, invoked from <a href="SXMLSimplify">SXMLSimplify</a>. <h2 id="head-55f8ebc805e65b5b71ddafdae390e3be2bcd69af">Description</h2>
<p>
This pass implements the <tt>TopLevel_setSuffix</tt> primitive, which installs a function to exit the program.

<p>
ImplementSuffix works by introducing a new <tt>ref</tt> cell to contain the function of type <tt>unit -> unit</tt> that should be called on program exit.
</p>
<ul>
<li>
<p>
The following code (appropriately alpha-converted) is appended to the beginning of the <a href="SXML">SXML</a> program:
<pre> val z_0 =
fn a_0 =>
let
val x_0 =
"toplevel suffix not installed"
val x_1 =
MLton_bug (x_0)
in
x_1
end
val topLevelSuffixCell =
Ref_ref (z_0)
</pre>
</p>
</li>
<li>
<p>
Any occurrence of
<pre> val x_0 =
TopLevel_setSuffix (f_0)
</pre> is rewritten to
<pre> val x_0 =
Ref_assign (topLevelSuffixCell, f_0)
</pre>
</p>
</li>
<li>
<p>
The following code (appropriately alpha-converted) is appended to the end of the <a href="SXML">SXML</a> program:
<pre> val f_0 =
Ref_deref (topLevelSuffixCell)
val z_0 =
()
val x_0 =
f_0 z_0
</pre>
</p>
</li>
</ul>
