What do you mean? This -> http://www.strchr.com/x86_machine_code_statistics

If not, please rephrase your question!

That's it!

While, mov is without doubt the most popular instruction in x86, the remaining of this statistics can be wrong.

It only demonstrates how MS VC++ 6.0 compiler uses the CPU instructions. In manually written assembly code, the distribution can be very different.

MOV is also overused in x86 because it also does loads and stores. Many other CPU instruction set mnemonics have separated out load and store from move. And some instruction sets don't even have move but use 'copy' (or a variant) instead.
