MLton runs fine on the Sparc architecture. <h2 id="head-70440046a3dc2e079f23ee1c57dfa76669b732aa">Notes</h2>
<ul>
<li>
<p>
When compiling for Sparc, MLton targets the 32-bit Sparc architecture (i.e., Sparc V8).
</p>
</li>
<li class="gap">
<p>
When compiling for Sparc, MLton doesn't support native code generation (<tt>-codegen native</tt>). Hence, performance is not as good as it might be and compile times are longer. Also, the quality of code generated by <tt>gcc</tt> is important. By default, MLton calls <tt>gcc -O1</tt>. You can change this by calling MLton with <tt>-cc-opt -O2</tt>. We have seen this speed up some programs by as much as 30%, especially those involving floating point; however, it can also more than double compile times.
</p>
</li>
<li class="gap">
<p>
When compiling for Sparc, MLton uses <tt>-align 8</tt> by default. While this speeds up reals, it also may increase object sizes. If your program does not make significant use of reals, you might see a speedup with <tt>-align 4</tt>.
</p>
</li>
</ul>
<h2 id="head-b05203cf89b60eb36609a1a8b7f3cafe0927486a">Known issues</h2>
<ul>
<li>
<p>
Bootstrapping on the <a href="RunningOnSparc">Sparc architecture</a> is so slow as to be impractical (many hours on a 500MHz UltraSparc). For this reason, we strongly recommend building with a <a href="CrossCompiling">cross compiler</a>.
