What static compiler could optimize when the JIT could not?

Question

Are there any examples of what a static compiler could optimize when JIT could not?

For example, some C ++ compiler optimization that cannot be performed by .NET JIT?

Answer 1

Missing. Evidence. Take any compiler and use it as a JIT. Q.E.D.

However , JIT is limited at run time, so complex optimizations are not acceptable there.

Answer 5

The main problem here is runtime and resources. It takes 61 hours to compile Visual Studio, and I don’t even know what their build machine is. JITs, however, should work with a fraction of real machine resources in milliseconds. There is no way that they can optimize so much.
