[PATCH] D94395: [X86] AMD Znver3 Scheduler descriptions and llvm-mca tests

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added reviewers: lebedev.ri, bkramer.
RKSimon added subscribers: lebedev.ri, bkramer.
RKSimon added a comment.

Adding @bkramer as IIRC he added the initial znver3 support, and @lebedev.ri who has added amd models in the past.

This mainly looks like a copy+tweak of the existing znver2 model (which itself was just a copy+tweak of the znver1 model), which I guess makes sense, but I don't have a 5000 series cpu to compare exegesis numbers.

----------------
Do you have the fpu pipe assignments for znver3 (or znver2 for that matter?)
