Compiler - Compiled versus interpreted languages

A compiler is a computer program that translates a series of statements written in one computer language (called the source code) into a resulting output in another computer language (often called the object or target language). Most compilers translate a source code text file, written in a high level language to object code or machine language, e.g. into an executable .EXE or .COM file that may run on a computer or a virtual machine. However, translation from a low level language to a high level one is also possible; this is n ...

Many people divide higher-level programming languages into compiled languages and interpreted languages. However, there is rarely anything about a language that requires it to be compiled or interpreted. Compilers and interpreters are implementations of languages, not languages themselves. The categorization usually reflects the most popular or widespread implementations of a language -- for instance, BASIC is thought of as an interpreted language, and C a compiled ...

Several experimental compilers were developed in the 1950s (see, for example, the seminal work by Grace Hopper on the A-0 language), but the FORTRAN team led by John Backus at IBM is generally credited as having introduced the first complete compiler, in 1957. COBOL was an early language to be compiled on multiple architectures, in 1960. [1] The idea of compilation quickly caught on, and most of the principles of compiler des ...

Compiler - Native versus cross compiler. Most compilers are classified as either native compilers or cross compilers. A compiler may produce binary output intended to run on the same type of computer and operating system ("platform") as the compiler itself runs on. This is sometimes called a native-code compiler. Alternatively, it might produce binary output designed to run on a different platform. This is known as a cross compiler. Cross compilers are very useful when bringing up a new hardware platform f ...

In the past, compilers were divided into many passes[1] to save space. A pass in this context is a run of the compiler through the source code of the program to be compiled, resulting in the building up of the internal data of the compiler (such as the evolving symbol table and other assisting data). When each pass is finished, the compiler can free the internal data space needed during that pass. This 'multipass' method of compiling was useful in the early days of computing due to the small main memories of host com ...

While there are applications where only the compiler front end is necessary, such as static language verification tools, a real compiler hands the intermediate representation generated by the front end to the back end, which produces a functional equivalent program in the output language. This is done in multiple steps: Compiler analysis - This is the process to gather program information from the intermediate representation of the input source files. Typical analysis are variable define-use and use-define chain, dependence anal ...
