Parrot – Virtual machine being developed mainly as the runtime for Raku, and intended to support dynamic languages like Python, Ruby, Tcl, etc. Psyco – specialized JIT compiler project that has mostly been eclipsed by PyPy; Pyrex – Python-like Python module development project that has mostly been eclipsed by Cython
The project's goal was to write a Java virtual machine in Java itself to avoid the problems of developing in C++, particularly manual memory management, and benefit from meta-circular optimizations. The project changed its focus to the compiler and to hook it into the HotSpot runtime as much as possible.
Wasm code (binary code, i.e. bytecode) is intended to be run on a portable virtual stack machine (VM). [101] The VM is designed to be faster to parse and execute than JavaScript and to have compact code representation. [52] Any external functionality (like syscalls) that may be
The term P-code machine is applied generically to all such machines (such as the Java virtual machine (JVM) and MATLAB pre-compiled code), as well as specific implementations using those machines. One of the most notable uses of P-Code machines is the P-Machine of the Pascal-P system.
Although the technique originated in Smalltalk, [1] the best-known language that uses this technique is Java. Since the machine code emitted by a dynamic compiler is constructed and optimized at program runtime, the use of dynamic compilation enables optimizations for efficiency not available to statically-compiled programs (i.e. those compiled ...
Currently JITing is used by most implementations of the Java Virtual Machine, as HotSpot builds on, and extensively uses, this research base. The HP project Dynamo was an experimental JIT compiler where the "bytecode" format and the machine code format were the same; the system optimized PA-8000 machine code. [12]
This list of JVM Languages comprises notable computer programming languages that are used to produce computer software that runs on the Java virtual machine (JVM). Some of these languages are interpreted by a Java program, and some are compiled to Java bytecode and just-in-time (JIT) compiled during execution as regular Java programs to improve performance.
