Dynamic recompilation
open-in-new
<p>In <a href="/facts/Computer_science/lN3pEyPz">computer science</a>, dynamic recompilation is a feature of some <a href="/facts/Emulator/FMHE8qDj">emulators</a> and <a href="/facts/Virtual_machine/BLevU3sx">virtual machines</a>, where the system may <a href="/facts/Compiler/WNfCDFJe">recompile</a> some part of a <a href="/facts/Computer_program/e38jH9N9">program</a> during execution. By compiling during execution, the system can tailor the generated code to reflect the program's run-time environment, and potentially produce more efficient <a href="/facts/Code/CSntvnEo">code</a> by exploiting information that is not available to a traditional static <a href="/facts/Compiler/WNfCDFJe">compiler</a>. </p>
