When QAing, it is very useful to be able to compare two .s files. This
means that we should strive for them being bit identical.
Does that mean we should do tons of work to make that happen, no, or
waste tons of compile time to make that happen, no. But, if at all
possible and reasonable to do, we should do it. For the harder cases,
just think of a long term strategy to make it work, and try and
socialize that direction to go in.
Agreed. I probably wouldn't have noticed the differences
if they didn't cause the compile to fail. If the differences
were benign, as I first though, I probably would have shrugged,
said "that's not good", and continued on.
