Stalin (Scheme implementation)

In computing, Stalin (STAtic Language ImplementatioN) is a <a href="/facts/Programming_language/cWTYbgWa">programming language</a>, an aggressive <a href="/facts/Optimizing_compiler/JXnv4LUd">optimizing</a> batch <a href="/facts/Interprocedural_optimization/LFFtj2yz">whole-program</a> <a href="/facts/Scheme_(programming_language)/0aGdf3SC">Scheme</a> <a href="/facts/Compiler/WNfCDFJe">compiler</a> written by Jeffrey Mark Siskind. It uses advanced data <a href="/facts/Data-flow_analysis/jz2oI6sX">flow analysis</a> and <a href="/facts/Type_inference/vX9K8Qhf">type inference</a> and a variety of other optimization methods to produce code. Stalin is intended for production use in generating an optimized <a href="/facts/Executable/VSst9eLA">executable</a>.
The compiler runs slowly, with little or no support for <a href="/facts/Debugging/QtdpPJT0">debugging</a> or other niceties. Full <a href="/facts/R4RS/0aGdf3SC">R4RS</a> Scheme is supported, with a few minor and rarely encountered omissions. Interfacing to external C libraries is straightforward. The compiler does <a href="/facts/Object_lifetime/QgCnhNlf">lifetime</a> analysis and hence does not generate as much <a href="/facts/Garbage_collection_(computer_science)/j2vlIu7g">garbage</a> as might be expected, but global reclamation of storage is done using the <a href="/facts/Boehm_garbage_collector/d5hNm3zM">Boehm garbage collector</a>.
The name is a joke: "<a href="/facts/Joseph_Stalin/SHtxGyQn">Stalin</a> brutally optimizes."
Stalin is <a href="/facts/Free_and_open-source_software/1cHtjLCB">free and open-source software</a>, licensed under a <a href="/facts/GNU_General_Public_License/S75KhLSX">GNU General Public License</a> (GPL), and is available online.
