Len Lattanzi retargeted the front end to generate MIPS ucode, modified the intermodule checker, and made the compiler generate entries that are as compatible with dbx as possible without actually changing dbx. The new compiler runs on DECStations under Ultrix. It will certainly not run on any big-endian MIPS machine, and I have no inclination to make it do so. It may run on other UNIX operating systems, but don't hold your breath. Since we have not yet merged source trees, this compiler is slightly different from the compiler recently announced for the VAX. The DECStation release contains just binaries, so you probably also want to retrieve the VAX version of the compiler, which contains extensive documentation. The MIPS file is about 460 kilobytes; the VAX file is about 3.4 megabytes. The release can be obtained from gatekeeper.dec.com, in the file /pub/DEC/Modula-2/m2.mips.tar.Z. (Internal DEC sites can retrieve over DECNET at decwrl::/pub/DEC/Modula-2/m2.mips.tar.Z) You should create the directory /usr/local/lib/mod, copy this file into it, then uncompress m2.mips.tar.Z tar xf m2.mips.tar ln -s /usr/local/lib/mod/mod /usr/local/bin/mod In this release, the passes of the compiler, the library file libmod.a, and all definition modules live in /usr/local/lib/mod. This should change in the next release to match the VAX version. Also, any bug fixes in m2/Bugs dated 1990 are not included; in particular, definition files must have an export list of some sort. Below is the announcement of the VAX compiler and licensing terms, for those missed the announcement a few days ago. The Western Research Laboratory of Digital Equipment Cor- poration is pleased to announce the availability of a new version of their Modula-2 compiler for VAXes running Ultrix or BSD. (The compiler has also been ported to the MIPS and to VMS; these versions should be available ``soon.'') The compiler was designed and built by Michael L. Powell, and originally released in 1984. Joel McCormack has since sped the compiler up, fixed lots of bugs, and stolen/written a User's Manual. The compiler appears to be one of the best compilers for the VAX in terms of efficiency of the gen- erated code. The error messages are quite a bit better than those from the Ultrix C compiler and the compile time is about the same as cc and gcc. Further, the compiler includes an intermodule checker that uses fine-grained dependencies rather than timestamps, so you can modify definition modules in upward-compatible ways without recom- piling the world. The compiler includes several extensions. The most notable are: provisions for interfacing with procedures and data types written in other languages like C and Pascal (a defin- ition module for the X11 C library is included); dynamic array variables, subarray parameters, and multi-dimensional open array parameters; inline procedures; complete support for the LONGFLOAT type; and a pseudo-module providing a type-checked interface to the C library I/O routines. In addition, the compiler front end can be conditionally compiled to generate a Pascal compiler that accepts a language almost identical to Berkeley Pascal. (Procedure parameters are not supported, and record layout and parame- ter passing conventions are somewhat different.) The distribution also includes a program that does most of the translation of Berkeley Pascal programs into Modula-2. The compiler is available for anonymous ftp from gatekeeper.dec.com, in the compressed tar file /pub/DEC/Modula-2/m2.vax.tar.Z. Once you have copied this file, you can uncompress it and untar it, like: uncompress m2.vax.tar.Z tar xf m2.vax.tar From there, read the README file, and the doc/installation.f file. The compiler is available to DEC sites over DECNET at decwrl::/pub/DEC/Modula-2/m2.vax.tar.Z. The compiler is also available by magnetic tape.

However, new users often find new bugs so we expect to hear from some of those who try it. No promises about bug fixes or new releases, though. -- - Joel McCormack (decwrl!joel, joel@decwrl.dec.com) -- comp.archives file verification gatekeeper.dec.com -r--r--r-- 1 root system 455697 Jul 2 1990 /pub/DEC/Modula-2/m2.mips.tar.Z found dec-modula-2 ok gatekeeper.dec.com:/pub/DEC/Modula-2/m2.mips.tar.Z
