I'd like to see the code a compiler generates when I compile a program. I know there is a way to do it, I just can find any info on it. Help? :) Additionally, where can I choose which optimizations are made when I build?

You can view the assembly that a the compiler spits out with any decent debugger. What compiler/IDE are you using?

For C++ I'm using VS2005, for C# I use either VS2005 or VS2008 express.

You can get MSVC to output the assembly it generates with the /FA family of switches. Optimizations can be controlled by going to Project Properties -> C/C++ -> Optimization.

I just put a breakpoint in the code I'm interested in and hit alt-8.
