I have created a new package for the GNU prolog compiler.
Note that I have only tested it on a i386 machine. It supports at
least the PPC and sparc architectures and could probably be made to
work without much difficulty (I think all the arch-specific stuff is
in the Ma2Asm directory). I'm neither an expert on prolog nor do I
have any other hardware to test it on, so I'm leaving this as an
exercise for the reader. :)
Here is an extract from the README file:
by Daniel Diaz
GNU Prolog is a native Prolog compiler with constraint solving over finite
domains (FD) developed by Daniel Diaz. Last information about GNU Prolog can
be found at http://www.gnu.org/software/prolog.
A lot of work has been devoted to the ISO compatibility. GNU Prolog is very
close to the ISO standard (http://www.logic-programming.org/prolog_std.html).
Here are some features of GNU Prolog:
- conforms to the ISO standard for Prolog (integer/floating arithmetic,
streams, dynamic code, exceptions).
- clause indexing.
- a lot of extensions: global variables, definite clause grammars (DCG),
sockets interface, operating system interface,...
- more than 300 Prolog built-in predicates.
- Prolog debugger and a low-level WAM debugger.
- line editing facility under the interactive interpreter with completion
- powerful bidirectional interface between Prolog and C.
- native-code compiler producing stand alone executables.
- simple command-line compiler accepting a wide variety of files:
Prolog files, C files, WAM files,...
- direct generation of assembly code 15 times faster than wamcc + gcc.
- most of unused built-in predicates are not linked (to reduce the size
of the executables).
- compiled predicates (native-code) as fast as wamcc on average.
- consulted predicates (byte-code) 5 times faster than wamcc.
- FD variables well integrated into the Prolog environment (full
compatibility with Prolog variables and
- integers). No need for explicit FD declarations.
- very efficient FD solver (comparable to commercial solvers).
- high-level constraints can be described in terms of simple primitives.
- a lot of predefined constraints: arithmetic constraints, boolean
constraints, symbolic constraints, reified constraints,...
- several predefined enumeration heuristics.
- the user can define his own new constraints.
- more than 50 FD built-in constraints/predicates.
