! Similar to http://en.wikipedia.org/wiki/Liveness_analysis,

! with three additions:
|

|
||||
! 1) With SSA, it is not sufficient to have a single live-in set
|
||||
! per block. There is also there is an edge-live-in set per
|
||||
! edge, consisting of phi inputs from each predecessor.
|
||||
! 2) Liveness analysis annotates call sites with GC maps
|
||||
! indicating the spill slots in the stack frame that contain
|
||||
! tagged pointers, and thus have to be visited if a GC occurs
|
||||
! inside the call.
|
||||
! 3) GC maps can contain derived pointers. A derived pointer is
|
||||
! a pointer into the middle of a data heap object. Each derived
|
||||
! pointer has a base pointer, to keep it up to date when objects
|
||||
! are moved by the garbage collector. This extends live
|
||||
! intervals and inserts new ##phi instructions.

<h1>Why Factor?</h1>
|
||||
|
||||
<p>The <big>Factor programming language</big> combines <a href="http://concatenative.org/wiki/view/Factor/Features/The%20language">powerful language features</a> with a <a href="http://docs.factorcode.org/content/article-vocab-index.html">full-featured library</a>. The implementation is <a href="http://concatenative.org/wiki/view/Factor/Optimizing%20compiler">fully compiled</a> for performance, while still supporting <a href="http://concatenative.org/wiki/view/Factor/Interactive development">interactive development</a>. Factor applications are portable between all common platforms. Factor can <a href="http://concatenative.org/wiki/view/Factor/Deployment">deploy stand-alone applications</a> on all platforms. Full source code for the Factor project is available under a <a href="http://factorcode.org/license.txt">BSD license</a>.</p>

<h1>Show me some code!</h1>
|
||||
|
||||
<p>Factor belongs to the family of <em><a href="http://concatenative.org/wiki/view/Concatenative%20language">concatenative languages</a></em>: this means that, at the lowest level, a Factor program is a series of words (functions) that manipulate a stack of references to dynamically-typed values. This gives the language a powerful foundation which allows many abstractions and paradigms to be built on top. Reload this page to see a random code example below.</p>
