Modeling modern x86 microarchitectures in Gem5

Hey everyone, I am working on modeling modern x86 cpu microarchitectures in
gem5 for my undergraduate research project. One major feature of x86 cpus
that is missing in gem5 is micro-op fusion. I found this project
https://github.com/darchr/gem5-skylake-config/tree/master in which the
authors have accounted for the absence of micro-op fusion by tweaking
microarchitectural parameters, but I would like to know if there are any
attempts to actually include the feature.

Thank you for your time
Madan
