40 When compiling for PowerPC, MLton targets the 32-bit PowerPC
46 When compiling for PowerPC, MLton doesn’t support native code
47 generation (<span class="monospaced">-codegen native</span>). Hence, performance is not as good as
48 it might be and compile times are longer. Also, the quality of code
49 generated by <span class="monospaced">gcc</span> is important. By default, MLton calls <span class="monospaced">gcc -O1</span>.
50 You can change this by calling MLton with <span class="monospaced">-cc-opt -O2</span>.
55 On the PowerPC, the <a href="GnuMP">GnuMP</a> library supports multiple ABIs. See
56 the <a href="GnuMP">GnuMP</a> page for more details.
