occam For All : Kent Retargetable Occam Compiler (KROC)

Version 0.9 Beta

News

31st March 1997

Release of KROC 0.9beta

• Inclusion of occam compiler supporting experimental user-defined operators with documentation to describe its use and two example implementations: DSTRING dynamic strings and COMPLEX32 & COMPLEX64 library.
• Updated the experimental synchronisation libraries: EVENTs, SEMAPHOREs, RESOURCEs and BUCKETs with new documentation.
• Numerous minor bug fixes.

5th November 1996

Release of KROC 0.81beta

• Fixed bug in which on exiting a program with ^C (SIGINT) failed to restore the keyboard state properly (for some programs).

31st October 1996

Release of KROC 0.8beta

• SP interface
  In version 0.7beta we provided link-library access to SP and SS PROTOCOLs as well as other INMOS libraries that provide the same functionality as the INMOS SP server. In this version, there is a PROTOCOL-compatible SP interface using a separate server process for full compatibility.
• kmakef: Makefile builder
  KROC has some extra dependencies that imakef (the INMOS tool) cannot know. We have written a tool that understands them and can build makefiles for KROC.
• Suspending (with ^Z from shell) programs and restarting them works correctly and saves/restores terminal state correctly.
• Buffered I/O is used on input from a non-terminal (when isatty() false)
• Improvements to kroc driver program.
• Experimental synchronisation libraries that allow multiple processes to synchronise safely in a variety of ways. Not documented yet but example programs are given.

18th March 1996

Release of KROC 0.7beta

• SGS-Thomson occam compiler I/O libraries now work to some extent: hostio.lib (SP protocol) and streamio.lib (SS, KS)
• The other standard libraries: convert.lib, string.lib dblmath.lib and snglmath.lib are also available.
• Exercises and course material for learning / teaching occam
• "An occam2.1 Checklist" document - introduction / reference to most of the language.
• Improvements / corrections to alpha arithmetic.
• Improvements to 'kroc' driver program (-oname, -Ldir, -Idir, -lname), configuration (no kroc.conf needed).
• Fixed bug in timeouts for sparcs
• Added support for jump-table use of kernel for use with dynamically loadable code (KERNEL.RUN) - not yet complete.
• Numerous minor bug fixes

23rd October 1995

Release of KROC 0.6beta

• Release of DEC Alpha/OSF 3.0 version of KROC. All the functionality of the sparc release is supported but separate compilation is not yet finished and there is still one cgtest failure (cgtest19 which tests the functions below).
• Added full INMOS 'compiler library' support (occam8.lib, occamutl.lib) for Sparc versions. This allows INT16 and INT64 support to work fully plus the 'obscure' IEEE functions. The summary of functions is:

12th October 1995

Release of KROC 0.5beta

• Fixed internal INT16 and INT64 support functions which were not working (in SPARC version) due to changes in the way that external functions were named (for separate compilation).
• lots of behind-the-scenes changes in preparation for ALPHA release
• Fixed bug with long PROC names in separately compiled modules

22nd September 1995

Release of KROC 0.4beta

• Added missing documents to release
• Separate compilation works better with driver. Example added.

18th September 1995

Release of KROC 0.3beta

• occam 2.1 compiler binary included
• occam/c interface tool (ocinf) included
• Support for Solaris 2.3
• Support for Separate Compilation (#USE)
• Support for more internal 'compiler library' routines
• Source tree format changed.

7th July 1995

Release of KROC 0.2beta

• Sources now compile with K&R and ANSI C compiler

4th May 1995

Release of KROC 0.1beta

Its all new.
