4 | MLton runs fine on the S390 architecture. | |

8 | * When compiling for S390, MLton doesn't support native code | |
9 | generation (`-codegen native`). Hence, performance is not as good as | |
10 | it might be and compile times are longer. Also, the quality of code | |
11 | generated by `gcc` is important. By default, MLton calls `gcc -O1`. | |
12 | You can change this by calling MLton with `-cc-opt -O2`. |
