  40 When compiling for HPPA, MLton targets the 32-bit HPPA architecture.

  45 When compiling for HPPA, MLton doesn&#8217;t support native code
  46 generation (<span class="monospaced">-codegen native</span>).  Hence, performance is not as good as
  47 it might be and compile times are longer.  Also, the quality of code
  48 generated by <span class="monospaced">gcc</span> is important.  By default, MLton calls <span class="monospaced">gcc -O1</span>.
  49 You can change this by calling MLton with <span class="monospaced">-cc-opt -O2</span>.
  50 </p>
  51 </li>
  52 <li>
  53 <p>
  54 When compiling for HPPA, MLton uses <span class="monospaced">-align 8</span> by default.  While
  55 this speeds up reals, it also may increase object sizes.  If your
  56 program does not make significant use of reals, you might see a
  57 speedup with <span class="monospaced">-align 4</span>.
