Hi,

How does the mapping between instruction inputs and outputs to the instruction bits-field is done?

From what I saw it either by name matching or by positional matching of unassigned bits-fields, and the two methods can't be mixed. Is it correct?

Supposing the above is correct then, setting inputs names in MIOperandInfo (of custom Operand) should behave as if they were specified directly in the out/ins list?

Thanks, Yaniv
