4 MLton runs fine on the AMD64 (aka "x86-64" or "x64") architecture.
8 * When compiling for AMD64, MLton targets the 64-bit ABI.
10 * On AMD64, MLton supports native code generation (`-codegen native` or `-codegen amd64`).
12 * When compiling for AMD64, MLton uses `-align 8` by default. Using
13 `-align 4` may be incompatible with optimized builds of the <:GnuMP:>
14 library, which assume 8-byte alignment. (See the thread at
