The G21 package

The G21 package collects the free source code for the Analog Devices GCC-based C compilers for their 21k (Sharc) and 21xx series DSPs. These compilers are all based on the GCC version 2.3.3.

This package is based on the source code made available from Analog Devices. It integrates 3 different compilers, and additionally contains the necessary changes and glue for easy installation on various Unices, as well as a few minor bug fixes and improvements.

Hosts

This version has mostly been tested under Linux/i386. Since all GCC host configuration files have been included, it will probably work under many other Unices with no or minimum work. The code does rely on the host using the IEEE float format.

To compile you will need, in addition to a good C compiler, various GNU tools like gperf and bison.

Altough it is believed that the compilers and tools are all right, they really have not been thoroughly verified for correctness.

What is missing?

Please also note that these packages contain the compiler, the assembler and the linker only. The source code for the Analog Devices debugger and emulator is also available, but porting to X and Unix has not been performed. Additionally, there is no library.

Availability

The G21 package in source code form is available from http://www.kvaleberg.org/pub/g21k-3.3.4PL3.tar.gz

The assembler and linker source code is available from http://www.kvaleberg.org/pub/g21k-binutils-PL4.tar.gz
