摘要：A processor contains a memory and a processing unit. The memory is of a typewhich loses data upon reading. The processing unit has instructions of a first type and ofa second type, each of which, when executed, causes the processing unit to read the datafrom the memory. Instructions of the first type cause the processing unit to restore thedata in the memory after reading, instructions of the second type cause the processingunit not to restore the data after reading. During compilation of a program, it is
determined whether a generated instruction that reads data from the location is the lastinstruction to do so. If so, an instruction of the second type is generated. If not, aninstruction of the first type is generated.
