In particular, just adding ".syntax unified" leads to other errors toto.s:3: Error: cannot honor width suffix -- `mul r3,r0,r3' toto.s:4: Error: cannot honor width suffix -- `mul ip,r2,r1'I'm not entirely sure about this error in the first case, since that ought to be valid as a 16-bit mul, shouldn't it?The 16-bit form is muls.

Thanks to both of you for your prompt support!Actually I have been using an ARM-v7M reference manual, which I thought to cover v6M too. I am trying to get a v6M manual to check if it's clearer.
I will try not to bother you more, as my problem seems related to understanding ARM manuals rather than using Code Sourcery tools :-)
(for example, I can't find the page which describes why the instructions involved implicitly require wide encodings)
Thanks Christophe.
