`A Retargetable C Compiler: Design and Implementation'
(Addison-Wesley, 1995, ISBN 0-8053-1670-1).
lcc is a production compiler with a hand crafted lexical analyzer and a
hand-coded recursive decent parser. The lexer and parser code is well
written and very easy to read (and learn from :-)).
lcc compiles much faster than FreeBSD's stock [gcc] compiler. However, it
does not under stand FreeBSD's "long long" data type.
