1 | SSA2Simplify |
| 2 | ============ | |
| 3 | ||
| 4 | The optimization passes for the <:SSA2:> <:IntermediateLanguage:> are | |
| 5 | collected and controlled by the `Simplify2` functor | |
| 6 | (<!ViewGitFile(mlton,master,mlton/ssa/simplify2.sig)>, | |
| 7 | <!ViewGitFile(mlton,master,mlton/ssa/simplify2.fun)>). | |
| 8 | ||
| 9 | The following optimization passes are implemented: | |
| 10 | ||
| 11 | * <:DeepFlatten:> | |
| 12 | * <:RefFlatten:> | |
| 13 | * <:RemoveUnused:> | |
| 14 | * <:Zone:> | |
| 15 | ||
| 16 | There are additional analysis and rewrite passes that augment many of the other optimization passes: | |
| 17 | ||
| 18 | * <:Restore:> | |
| 19 | * <:Shrink:> | |
| 20 | ||
| 21 | The optimization passes can be controlled from the command-line by the options | |
| 22 | ||
| 23 | * `-diag-pass <pass>` -- keep diagnostic info for pass | |
| 24 | * `-disable-pass <pass>` -- skip optimization pass (if normally performed) | |
| 25 | * `-enable-pass <pass>` -- perform optimization pass (if normally skipped) | |
| 26 | * `-keep-pass <pass>` -- keep the results of pass | |
| 27 | * `-loop-passes <n>` -- loop optimization passes | |
| 28 | * `-ssa2-passes <passes>` -- ssa optimization passes |
