Problem
I’m not sure how the compiler will recognize when it’s time to compile for 64-bit when it’s needed. How does it know when it’s safe to go for 32-bit?
I’m particularly interested in how the compiler determines which architecture to target while compiling. Is it capable of analyzing the code and making a conclusion depending on what it discovers?

If you don’t want to utilize extra memory with 64-bit applications, this is the explanation. That is, if your application is AnyCPU, you should run it in 32-bit mode.
To add to that, Visual Studio has a setting that targets a specific CLR:
