Actually, -mabi=iwmmxt is AAPCS based. It's diffferent from the old intel iwmmxt ABI. Having said that, it probably hasn't been tested particularly well, and I wouldn't advise using it unless you really need it (ie. you know you have performace sensitive code that makes extensive use of iWMMXt vector types in function arguments).
