Bootstrap (compiler)

See also: Bootstrap

In Data-processing, the term bootstrapping describes the techniques used to write a Compilateur (or a Assembleur) in the Computer programming language target which it must compile.

One can wonder how to solve this Paradoxe of egg and the hen: if one needs a compiler for language X in order to obtain a compiler for language X, how the first compiler was written?

Implanter a interprets or a Compilateur for language X in language Y.
Another interpreter or compiler was written for X in a language Y. Thus Scheme is often bootstrappé.
Of the initial versions of the compiler is written in a subset of X for which there existed another compiler. Thus supersets of Java are bootstrappés.
the compiler of X is cross of another architecture for which there exists a compiler for X. Thus one generally carries worms of other platforms the compilers for the C.
By writing the compiler optimizing X, then by compiling it with the hand starting from its Source code (probably in a not optimized way) and while turning the code obtained to obtain the optimizing compiler.

The methods to distribute compilers in source code include the supply of a portable Bytecode of the compiler, in order to bootstrapper the system of compilation of the compiler with itself.

NELIAC was the first language required such a bootstrap. PL/I was the first commercial language to do it.
Aujourd'hui, a broad proportion of the computer programming languages are bootstrappés, therefore C, Scheme, Ocaml, Pascal, Modulated-2, Oberon and more.
