WinDbg is a multipurpose debugger for the Microsoft Windows computer operating system, distributed by Microsoft. [2] Debugging is the process of finding and resolving errors in a system; in computing it also includes exploring the internal operation of software as a help to development.
Graal Compiler, a just-in-time (JIT) compiler. GraalVM Native Image is a technology to compile Java applications ahead of time. Truffle Language Implementation Framework and GraalVM SDK, a Java-based framework and a collection of APIs for developing high-performance language runtimes.
The earliest published JIT compiler is generally attributed to work on LISP by John McCarthy in 1960. [4] In his seminal paper Recursive functions of symbolic expressions and their computation by machine, Part I, he mentions functions that are translated during runtime, thereby sparing the need to save the compiler output to punch cards [5] (although this would be more accurately known as a ...
On the x86 architecture, a debug register is a register used by a processor for program debugging. There are six debug registers, named DR0...DR7, with DR4 and DR5 as obsolete synonyms for DR6 and DR7. The debug registers allow programmers to selectively enable various debug conditions associated with a set of four debug addresses.
Interpreter debug options can enable the collection of performance metrics as the interpreter encounters each target statement. A bytecode , control table or JIT interpreters are three examples that usually have complete control over execution of the target code, thus enabling extremely comprehensive data collection opportunities.
The line-oriented debugger DEBUG.EXE is an external command in operating systems such as DOS, OS/2 and Windows (only in 16-bit/32-bit versions [1]).. DEBUG can act as an assembler, disassembler, or hex dump program allowing users to interactively examine memory contents (in assembly language, hexadecimal or ASCII), make changes, and selectively execute COM, EXE and other file types.
WebAssembly implementations usually use either ahead-of-time (AOT) or just-in-time (JIT) compilation, but may also use an interpreter. While the first implementations have landed in web browsers, there are also non-browser implementations for general-purpose use, including Wasmer, [10] Wasmtime [42] or WAMR, [16] wasm3, WAVM, and many others.

The Just-In-Time (JIT) improves the performance of Java applications by compiling platform-neutral Java bytecode into native machine code at run time. Not every method that gets called by an application is compiled. Instead, OpenJ9 records the number of times a method is called and triggers JIT compilation at a predefined threshold.
