There is no requirement of course, but some good reasons to write a compiler in its own language: 1) There is in general a commonality between a language, its representation, and the structures it handles best. Representing the language with its own structures is generally appropriate. 2) It makes porting the compiler to other machines easier (description of why is to be found in any good book about compilation) 3) Compiling the compiler with itself is an excellent test: the 2nd compilation should be identical to the third compilation, or there is something wrong... -- J-P.
