The Z80 assembler

Welcome to the homepage of the Z80 assembler, hosted by savannah, which is part of the GNU project. If you don't know what the GNU project is, then please read the above link. If you don't really know what the GNU project is, but you think you know what Linux is, then you should really read this article.

Now then, let's talk about the assembler. The goal of The Z80 assembler project is having a free, easy to expand, easy to use assembler. Free as in free speech, that is. Especially for an assembler, it is very likely that the users will want to read the source code, perhaps modify it and redistribute it. With this Z80 assembler, all this is possible, because it is licensed under the GNU General Public License.

It is written in ansi C, which means it should compile on any good platform. It has been tested on GNU/Linux and it works there.

Features

• All official mnemonics are recognized.
• Most unofficial mnemonics are recognized.
• Very complex expressions are allowed (bash style).
• Other source files can be included.
• Code can contain conditional parts.
• Beside the binary output file, a label file can be output with a list of all labels in the program. This label file is includable by other source files, so linker-like functionality can be obtained with it.
• There is support for listing files, with the input code and the assembled result next to each other.

Documentation

Documentation for the assembler can be found here.
