For the record, I don't and have not done ports.
Rather I was interested in introducing a scaled math header. It would contain routines to allow access to the 64 bit mpy and div instructions, which ,of course, can be done in C but, if you don't want the 64-bit lib, must be done with a rather large bit of code to do simple s32=s64/s32 and s32=s64%s32 calculations. And, on 64-bit archs the whole problem goes away. > > I see absolutely no value whatsoever to what you are proposing. > In fact, I frankly think it sucks. :(
I understand what you think, but don't understand why you think that :( > >
