Evaluation or Free compiler ?

I've been working on porting various ARM DSP optimizations to different open source libraries to reduce power consumption on ARM devices.  Unfortunately while I'm happy with gcc, a lot of commercial users complain that things like ASM code don't link when used with the ARM ltd. compiler.  Since I don't have access to it I can't look into it.  This has led to a few commercial products shipping with poor performance and battery life.

Is it possible to get access to the official ARM compiler/assembler somehow for testing?  I'm a student with no money doing this for fun, so paying for it isn't going to work, but I don't need to actually do development, just testing so maybe theres some free tool available for doing this?

Thanks for any help.
