Thank you @gganesh I thought you'd forgotten about us :)
Please add znver4 test coverage to:
llvm/test/CodeGen/X86/cpus-amd.ll
llvm/test/CodeGen/X86/slow-unaligned-mem.ll
================
Comment at: llvm/lib/Target/X86/X86.td:1619
ProcessorFeatures.ZN3Tuning>;
+def : ProcModel<"znver4", Znver3Model, ProcessorFeatures.ZN4Features,
+ ProcessorFeatures.ZN4Tuning>;
----------------
This might sound strange - but its probably better to use either the IceLake or
SkylakeServer model initially - as they have AVX512 instruction coverage, the
znver3 model will assert in llvm-mca etc when it encounters an unsupported
instruction (any of the Z sched classes).
