Line 73:

* The open source SGI compiler [http://ipf-orc.sourceforge.net/ ORC] uses SSA form in its global scalar optimizer, though the code is brought into SSA form before and take out of SSA form afterwards. ORC uses extensions to SSA form to represent memory in SSA form as well as scalar values.

* As of summer [[2004]] the [[GNU Compiler Collection]] is being updated to use SSA form. The [[frontend|frontends]] generate [[GENERIC]] code which is then converted into SSA form by the "[[gimplifier]]" and optimized by the "[[middle-end]]". The [[backend]] eventually translates the optimized intermediate code into [[Register Transfer Language|RTL]], executes some more low-level optimizations and finally turns RTL into [[assembly codelanguage]]. The first official release supporting SSA will be 3.5, tentatively scheduled for early [[2005]].
