These are the comments as I received them from Albert Koelmans.
|
|
|
|
|
The only thing I did was adapt the installation mechanism for ACK, and
|
|
|
|
|
made some adaptions to de code generator to support the improved FP package.
|
|
|
|
|
I also removed some comments that were no longer up-to-date.

AMSTERDAM COMPILER KIT - BACKEND FOR ACORN RISC MACHINE PROCESSOR
|
|
|
|
|
===========================================================================
|
|
|
|
|
|
|
|
|
|
This file contains some advice on how to go about installing the ARM backend
|
|
|
|
|
for the Amsterdam Compiler Kit (ACK), followed by a shar file containing the
|
|
|
|
|
backend itself. In what follows, ~ will denote the ACK root directory (on
|
|
|
|
|
most systems, this will be /usr/em), also called EMHOME in most makefiles.
|
|
|
|
|
|
|
|
|
|
Make sure that your PATH includes ~/bin
|
|
|
|
|
|
|
|
|
|
cd to ~/bin, and type
|
|
|
|
|
ln ack arm
|
|
|
|
|
|
|
|
|
|
cd to ~/mach/proto/ncg, and inspect file param.h. The constant MAXEMLINES
|
|
|
|
|
should be at least 40. Edit the file if necessary.
|
|
|
|
|
|
|
|
|
|
cd to ~/util/ncgg, and inspect file param.h. The constant MAXNODES should
|
1990-12-19 11:52:37 +00:00
|
|
|
have as parameter at least 1200. If this is not the case, edit the
|
1990-11-13 13:36:15 +00:00
|
|
|
file and type 'make install' to generate a new ncgg.
|
|
|
|
|
|
|
|
|
|
If some compilations fail, inspect file Out in the appropriate subdirectory
|
|
|
|
|
to find the cause.
|
|
|
|
|
|
|
|
|
|
ACK will create an a.out file which includes an ACK header and symbol table.
|
|
|
|
|
Use the cv program to strip these off, after which the executable should be
|
|
|
|
|
downloaded onto an Archimedes machine and have it's type set to FF8.

Acknowledgements: the first version of the backend was written by an anonymous
|
|
|
|
|
student at the Vrije Universiteit, Amsterdam. The code generator was further
|
|
|
|
|
developed and debugged by Albert Koelmans. Andrew Michael wrote most of the
|
|
|
|
|
assembler sources. A simple RiscOs interface was added by Albert Koelmans.
|
|
|
|
|
All of this involved extensive help from Ceriel Jacobs. The assertion in the
|
|
|
|
|
ACK documentation that writing a backend is a major task is certainly true...
