Compiler
--------
This is a simple but full-featured one-pass ETH compiler based on the
original OOP compiler by Regis Crelier and modified to produce PPC
code by Markus A. Hof. The original compiler runs on Oberon System 4
on a Power Mac.  This version runs from the command line and will
produce PPC ETH object and symbol files on any platform which has
support for oo2c.  OO2C is available for PPC BeOS from
http://www.inspired.to/be.

If anyone would like to modify the code to produce XCOFF output
files and would like to work on the necessary runtime to get the
object files linkable on PPC BeOS, please contact me.  I have
some additional runtime and loader source and would be happy to
give advice on the porting effort.

Invocation syntax is: Compiler [options] <oberon module> {[oberon
module]}.

The following command line options are supported:

    -h         Print this text
    -d         Show intermediate syntax tree
    -x         Index check on
    -v         Overflow check on
    -r         Range check on
    -t         Type check on
    -s         Generation of new symbol file allowed
    -p         Pointer initialization
    -n         NIL pointer checks on read accesses
    -a         Assert evaluation
    -f         Find text position of breakpc
    -c         Use PowerPC instruction set
    -w         Suppress warning 301

The default options are -x -t -n -p -a -c.  Adding these options to
the command line will toggle the appropriate flags.

Sorry, a "Make" facility isn't currently available.  It may be
possible to port the Oberon system Make to work from a command line,
but I haven't investigated this possibility yet.

NOTE: I haven't tested this compiler very much and don't plan to do so
for this version.  I will be producing another version which has a
code generator for the PIC series of microcontrollers.

This compiler may be useful to anyone porting the Oberon system to
another PPC platform which doesn't currently have an Oberon System
available.  If this is the case, I have the full Oberon System source
code, including the loader, so contact me at the email address above.

This version of the source has been modified to work with the current
set of OOC library modules.


Decode
------

This utility is part of the Oberon System.  It basically decodes the
Obj output from the compiler to give a disassembled version of the
object code and some additional information about symbolic references,
pointers, etc.

Invocation:  Decode <oberon object>


Disclaimer
----------

This compiler IS NOT supported in any way so if you can use it, great
but I can't promise to fix any problems you may encounter.  I am
interested in hearing about bugs though, so please send me email.
