| 4 | <:Machine:> is an <:IntermediateLanguage:>, translated from <:RSSA:> |
| 5 | by <:ToMachine:> and used as input by the <:Codegen:>. |

| 7 | == Description == |
| 8 | |
| 9 | <:Machine:> is an <:Untyped:> <:IntermediateLanguage:>, corresponding |
| 10 | to a abstract register machine. |

| 16 | |
| 17 | == Type Checking == |
| 18 | |
| 19 | The <:Machine:> <:IntermediateLanguage:> has a primitive type checker |
| 20 | (<!ViewGitFile(mlton,master,mlton/backend/machine.sig)>, |
| 21 | <!ViewGitFile(mlton,master,mlton/backend/machine.fun)>), which only checks |
| 22 | some liveness properties. |
| 23 | |
| 24 | == Details and Notes == |
| 25 | |
| 26 | The runtime structure sets some constants according to the |
| 27 | configuration files on the target architecture and OS. |
