Actually I think debugging should be straightforward if they use the same convention. Except a little extra would be needed where the instruction set changes where there would be a bit extra needed for getting the correct return address instead of the routine to change instruction sets. Yes you'd need to check whether an area is ARM or x86 when setting a breakpoint but that's hardly the end of he world. Run time generated code might be a bit iffy though!
