It might be nice to create a reference(if there isn't already one) to document popular compiler optimizations and their C/C++ counterparts. For example, the assembley code and explanation for a = b ? c : d; and other things like that.

Yoni has something similar that he just posted in another thread.

Also, if you want one, make one. Just write it yourself and disassemble it :P

You could start by making a thread here posting them one by one. Don't discuss them in that thread, just use it to build up a reference.
