Every Intel® XED iform belongs to one xed_isa_set_enum_t. Each Intel® XED chip of type xed_chip_enum_t represents a collection of xed "isa-sets". If you have a xed_decoded_inst_t, you can get the isa set via the function xed_decoded_inst_get_isa_set.
Intel® XED chip-check supports the detection of all Intel® APX instructions and flavors, whether be it a new Intel® APX instruction, legacy instruction with REX2 prefix, EVEX instruction with EGPR as one of its operands (register or memory) or EVEX instruction with ignored EGPR encoding.

◆ xed_isa_set_is_valid_for_chip()
return 1 if the isa_set is part included in the specified chip, 0 otherwise.
