Instruction construction method, apparatus and device, and readable storage medium

The embodiment of the invention provides an instruction construction method and device, equipment and a readable storage medium. Relates to the technical field of computers. The method comprises the following steps: acquiring a byte code instruction, and searching a feature identifier corresponding to the byte code instruction in a preset array; the feature identifier is used for identifying the processor architecture and comprises a plurality of bit fields; the bit field records feature information corresponding to the byte code instruction; analyzing each corresponding target bit field in the feature identifier, and respectively obtaining target feature information correspondingly recorded in the target bit fields; and determining an instruction construction operation corresponding to the target feature information to obtain a machine code instruction corresponding to the byte code instruction. According to the method and the device, the feature information is recorded in the bit field in the feature identi
