Hello Everyone, I hope you are all doing well!
I am trying to implement a store instruction in ARM that has Post-index, Pre-index, and Signed-offset versions, and I'm using a normal store (i.e., STRX64) as a model to start, but I am running into some confusion with regard to which versions are microops, macroops, and neither, so I was wondering if anyone had any clarification on the issue I am seeing information about the differences in X86, but I haven't been able to find anything about it in ARM Here is what I've gathered so far: STRX64_REG → neither (not IsMicroop/IsMacroop) STRX64_PRE → IsMacroop (uses microop MicroAddXiUop) STRX64_POST → IsMacroop (uses microop MicroAddXiUop) STRX64_IMM → neither (not IsMicroop/IsMacroop) STRX64_PREAcc → IsMicroop STRX64_POSTAcc → IsMicroop From my understanding, the macroop is broken down into microops, but I am confused as to why some of the others are listed as microops and some are listed as neither. If anyone has any insight into how these are different and how they are used, it would be greatly appreciated Thank you for your time!
