The cmov mess is because SSE and 64-bit odegen assumes cmov exists. We couldn’t make 64-bit or SSE imply cmov feature or -mattr=-cmov would disable SSE or 64bit which is just completely broken. Thus the OR that ignores attempts to disable cmov.

+ // TrivalField - Auto-generate a trival field for this feature.
+ // A trival field is always zero-initialized.
