The main point of that test is to run the code that does some int 
operation lowering (division, modulus and absolute value; well, there is 
not absolute value, I'll add it), patches still to be contributed. SM4 
doesn't represent those operations directly and rather requires some 
more complicated code to emulate them. I guess this doesn't happen in 
SM1, given that those operations are silently converted to float anyway, 
so I didn't consider it a priority anyway. But I can do what you suggested.

Giovanni.
