Note: To decrease the size of the object files, I disabled linking. Let me tell you if there are other things you may find useful.
Hmm - it is probably a case of ADS and GAS using different methods to distinguish between ARM and THUMB code in their object files. Please could you send me a *small* ADS object file which demonstrates this problem, so that I can try to find a fix ?
Cheers
Nick
