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
