The optimization passes for the SXML IntermediateLanguage are collected and controlled by the SxmlSimplify functor ( sxml-simplify.sig , sxml-simplify.fun ).

The following optimization passes are implemented:

• Polyvariance

• SXMLShrink

The following implementation passes are implemented:

• ImplementExceptions

• ImplementSuffix

The following optimization passes are not implemented, but might prove useful:

• Uncurry

• LambdaLift

The optimization passes can be controlled from the command-line by the options

• diag-pass <pass> -- keep diagnostic info for pass

• drop-pass <pass> -- omit optimization pass

• keep-pass <pass> -- keep the results of pass

• sxml-passes <passes> -- sxml optimization passes
