OT, but there's lots of cool data on all of this on
I spent some time some time ago to file a few "missed optimizations"
bugzillas based on examples there and some got addressed. I'm sure
there are lots more nuggets in there (as in easy cases to improve
gcc), but analyzing each example takes time.
The reason each sample takes time to analyze is that it is sometimes
a bug in the other compiler or different target options or so.
Sometimes it's also undefined code.
Yes there are plenty of bugs in there, but I didn't find any for gcc
at least (but only looked at a relatively limited set)
