With decode time instruction optimization code link for enhanced application binary interface (ABI)

摘要

The present invention using a decoding time instruction optimization method for linking code for enhanced application binary interface (ABI), and to provide a system and a computer program . In A the object file , and is composed of a plurality of instructions , and the code sequence which specifies the offset from the base address is identified . Offset from the base address corresponds to the offset location in the memory configured to store an address or database of variables . Identified code sequence is configured to implement the memory reference function or memory address calculation functions . Offset position is within a distance that is specified in the base address , the substitution of substitution code sequences of the identified code sequence that does not change the program semantics are determined . Identified code sequence in the object file is replaced by non-operation (NOP) replace the code sequences having fewer instructions or identification code sequence includes instructions . Linked executable code is generated based on the object file , linked executable code is issued . [ Selection Figure Figure 5
