| 4 | The optimization passes for the <:SSA:> <:IntermediateLanguage:> are | |
| 5 | collected and controlled by the `Simplify` functor | |
| 6 | (<!ViewGitFile(mlton,master,mlton/ssa/simplify.sig)>, | |
| 7 | <!ViewGitFile(mlton,master,mlton/ssa/simplify.fun)>). | |
| 8 | ||
| 9 | The following optimization passes are implemented: | |
| 10 | ||
| 11 | * <:CombineConversions:> | |
| 12 | * <:CommonArg:> | |
| 13 | * <:CommonBlock:> | |
| 14 | * <:CommonSubexp:> | |
| 15 | * <:ConstantPropagation:> | |
| 16 | * <:Contify:> | |
| 17 | * <:Flatten:> | |
| 18 | * <:Inline:> | |
| 19 | * <:IntroduceLoops:> | |
| 20 | * <:KnownCase:> | |
| 21 | * <:LocalFlatten:> | |
| 22 | * <:LocalRef:> | |
| 23 | * <:LoopInvariant:> | |
| 24 | * <:LoopUnfoll:> | |
| 25 | * <:LoopUnswitch:> | |
| 26 | * <:Redundant:> | |
| 27 | * <:RedundantTests:> | |
| 28 | * <:RemoveUnused:> | |
| 29 | * <:ShareZeroVec:> | |
| 30 | * <:SimplifyTypes:> | |
| 31 | * <:Useless:> | |
| 32 | ||
| 33 | The following implementation passes are implemented: | |
| 34 | ||
| 35 | * <:PolyEqual:> | |
| 36 | * <:PolyHash:> | |
| 37 | ||
| 38 | There are additional analysis and rewrite passes that augment many of the other optimization passes: | |
| 39 | ||
| 40 | * <:Multi:> | |
| 41 | * <:Restore:> | |
| 42 | * <:Shrink:> | |
| 43 | ||
| 44 | The optimization passes can be controlled from the command-line by the options: | |
| 45 | ||
| 46 | * `-diag-pass <pass>` -- keep diagnostic info for pass | |
| 47 | * `-disable-pass <pass>` -- skip optimization pass (if normally performed) | |
| 48 | * `-enable-pass <pass>` -- perform optimization pass (if normally skipped) | |
| 49 | * `-keep-pass <pass>` -- keep the results of pass | |
| 50 | * `-loop-passes <n>` -- loop optimization passes | |
| 51 | * `-ssa-passes <passes>` -- ssa optimization passes |
