when building using binutils 2.20: - swi inst now requires an argument. - msr psp,sp is not allowed.
I'll let Nick handle this patch, but I'm curious (and admittedly haven't looked at the ISA details): it seems strange that msr psp,sp used to be allowed but now is not - and presumably it worked on the hardware otherwise it wouldn't have been in the port.
Cheers Spen
