ToSSA2
======

<:ToSSA2:> is a translation pass from the <:SSA:>
<:IntermediateLanguage:> to the <:SSA2:> <:IntermediateLanguage:>.

== Description ==

This pass is a simple conversion from a <:SSA:> program into a
<:SSA2:> program.

The only interesting portions of the translation are:

* an <:SSA:> `ref` type becomes an object with a single mutable field
* `array`, `vector`, and `ref` are eliminated in favor of select and updates
* `Case` transfers separate discrimination and constructor argument selects

== Implementation ==

* <!ViewGitFile(mlton,master,mlton/ssa/ssa-to-ssa2.sig)>
* <!ViewGitFile(mlton,master,mlton/ssa/ssa-to-ssa2.fun)>
