RunningOnPowerPC

MLton runs fine on the PowerPC architecture.

Notes

When compiling for PowerPC, MLton targets the 32-bit PowerPC architecture.
When compiling for PowerPC, MLton doesn’t support native code generation (-codegen native). Hence, performance is not as good as it might be and compile times are longer. Also, the quality of code generated by gcc is important. By default, MLton calls gcc -O1. You can change this by calling MLton with -cc-opt -O2.
On the PowerPC, the GMP library supports multiple ABIs. See the GMP page for more details.
