If one needs to compile a compiler for language X written in language X, there is the issue of how the first compiler can be compiled. The different methods that are used in practice include: Implementing an interpreter or compiler for language X in language Y. Niklaus Wirth reported that he wrote the first Pascal compiler in Fortran. [7]
Join Java, a language that extends Java with join-calculus semantics; Joy; Manifold is a Java compiler "plugin." (I.e., instead of being a stand-alone language and compiler, it hijacks and extends javac.) Its features include Metaprogramming, Properties, Extension Methods, Operator Overloading, Templates, a Preprocessor, and more.
It can compile to source code in C++, JavaScript, PHP, C#, Java, Python, and Lua. Haxe also has an interpreter called eval . [ 16 ] This same interpreter is also used compile-time to run macros, which allow modification of the abstract syntax tree (AST).
The Skewb (/ ˈ s k juː b /) is a combination puzzle and a mechanical puzzle similar to the Rubik's Cube. It was invented by Tony Durham and marketed by Uwe Mèffert . [ 1 ] Although it is cubical, it differs from the typical cubes ' construction; its axes of rotation pass through the corners of the cube, rather than the centers of the faces.
Zend Engine is used internally by PHP as a compiler and runtime engine. PHP Scripts are loaded into memory and compiled into Zend opcodes. These opcodes are executed and the HTML generated is sent to the client. [6] To implement a Web script interpreter requires three parts: The interpreter part analyzes the input code, translates it, and ...
Compilers are more ideal when protecting code from plagiarism and preventing the use of source code from an unauthorized party. Object code only needs to be created once when compiling source code. There are clear disadvantages when translating high-level code with a compiler. [7] This image represents the translation process through a compiler.
The GCJ Java compiler can target either a native machine language architecture or the Java virtual machine's Java bytecode. [82] When retargeting GCC to a new platform, bootstrapping is often used. Motorola 68000, Zilog Z80, and other processors are also targeted in the GCC versions developed for various Texas Instruments, Hewlett Packard ...
