Compiler flags. You turn on/off compiler optimisations for target architectures that are aware of all the instruction-set specific hardware level optimisations.

But I'm not compiling. And neither are 99.9% of other software users.

Hence why JITs have some advantages when shipping software, at the cost of a few extra MBs.

Only if the JIT uses the fancy instructions :)

Most JVM implementations and the CLR do keep up with fancy instructions.

Not all, but surely a few.
