Contify is an optimization pass for the SSA IntermediateLanguage, invoked from SSASimplify.

Description

Contification is a compiler optimization that turns a function that always returns to the same place into a continuation. This exposes control-flow information that is required by many optimizations, including traditional loop optimizations.

Implementation

contify.sig contify.fun

Details and Notes

See Contification Using Dominators. The intermediate language described in that paper has since evolved to the SSA IntermediateLanguage; hence, the complication described in Section 6.1 is no longer relevant.
