I'm familar with IAR, and I also like it. But I'm looking for an 
assembler to use in a new IDE I'm writing for students. Colleges 
normally can't use commercial tools even if they're clearly free for 
limited versions.

Part of the problem is that professors don't like trying to coordinate 
things with their legal department. They frequently use GNU tools, but 
they normally ask me for a simple IDE that supports an open source 
assembler that uses a standard syntax.

My current IDEs are only for the Freescale hc11/hc12 series but I'm 
looking at supporting the ARM in my forthcoming C# IDE.

Let me know if anyone knows of a nice open source ARM assembler for 
linux or Windows, other than GNU "as".
