Hmm, I don't really trust this. It possibly works for easy situations, but 
I have seen to much "this should be optimized out" code remain in release 
versions to really rely on that feature.

I know sometimes I'm old-fashioned (not wanting git, don't using all 
these fancy new tools for specific tasks, not relying on compiler 
automatics, ...), but most of this comes from experience: E.g. if you do 
re-engineering of Assembler code to find a bug in your software and find, 
that the compiler is broken you loose your trust in compilers.

I hope you all can live with that. :-)

P.S. I'm even one of the few people not using IDE's at all, as I learned 
programming before graphical-all-in-one-interfaces became available. Which 
on the other hand means I still can work from 80x25 ASCII remote terminals 
without any problems.
