I look CMO spec, and I feel that cmo don't manage icache.
So I am confused.

You are correct. The CMO spec focuses on management of data caching. The separate "I/D Consistency" extension that is in the works in the J group specifically focuses on management of instruction caching - especially in the context of self and cross modifying code (such as occurs with JIT'ed languages for example).
