MICRO AE.exp does not specify the llc_prefetcher_types

Hello. MICRO AE.exp does not specify the llc_prefetcher_types. Why does multi.llc_pref not output the message "unsupported prefetcher type "?

[szuhzw]

Can anyone resolve my doubts?

HI @szuhzw, the llc_prefetcher_types is a knob of type vector of strings (src/knobs.cc:22). If you have have not specify llc_prefetcher_types knob, the vector will be of size 0, in which case the code inside the for loop at prefetcher/multi.llc_pref:26 will not even execute. Hence, there won't be any log saying "unsupported prefetcher types". The log will be printed if and only if you have passed an invalid prefetcher name with llc_prefetcher_types knob.

Closing the issue for now. If needed, we can reopen.
