Does the .NET CLR Really Optimize for the Current Processor

Question

When I read about the performance of JITted languages like C# or Java, authors usually say that they should/could theoretically outperform many native-compiled applications.

Answer 1

I know the rules for whether or not to inline functions changes depending on the processor type (x86, x64). And of course the pointer sizes will vary depending on if it runs as 32-bit or 64-bit.
