The LCC compiler is a portable C compiler, written by Chris Fraser & David Hanson. It is described in
detail in their new book ``A Retargetable C Compiler: Design and
Implementation'' (Benjamin Cummings, 1995, ISBN 0-8053-1670-1). You can get
the current distribution by ftp.
One of the nicest new languages is (Concurrent) Clean from the KU Nijmegen. A text-only version of the 0.8
language manual is locally
present. Initially, Clean was intended as a intermediate
representation, not a "real language"; but users have been quite
enthusiastic about it. Clean's somewhat strange syntax will be changed to
something Haskell-like (The Haskell
1.2 report is available as a local DVI file). The semantics of
Clean provides the notion of uniqueness types. If a function
parameter is unique, the type system guarantees that arguments
passed to it don't exist anywhere else. (There is a connection to
linear types, but I am not quite sure what it is. I have not yet seen the
formal semantics of Clean.) Declaring a parameter unique enables all
kinds of nifty optimizations (e.g. in-place updating of arrays). Uniqueness
types also provide for an interesting alternative and/or extension to the
monadic style of state plumbing.

CBC is a project devoted to the development of a retargetable microcode
compiler for digital signal processor core architectures. It was part of
the ESPRIT project SPRITE. CBC employs the instruction set description
formalism nML to describe target architectures. For further info about CBC,
ask Andreas Fauth. Sorry for the atrocious mark-up,
the CBC page mostly contains stuff made by the TeX2html converter.
PRECC (PREttier Compiler Compiler) is a LR-infinity
parser tool build upon combinatorial parsing. Its authors are John Bowen
and Peter Breuer. It is much more powerful than standard tools such as
yacc, but the current implementation is not very luxurious with regards to
syntactic and semantic errors in the precc specification. It can also be
dead slow, in that the generated parsers are somewhat naive (as far as I
understand them, they don't cache partial parses when backtracking). Three papers describe applications of precc.

includes stuff from version 2.30 and 2.40)
