Abstract
An instruction string optimization apparatus is provided which estimates the size of a constant to be resolved as an address difference before linking instructions. The apparatus comprises code dividing means ( ) for dividing a serial assembler code ( ) into basic blocks, size dependence relation generation means ( ) for analyzing size dependence relations among the sizes of the instruction string between basic blocks, estimation order determining means ( ) for determining the order of basic blocks in which the size of a constant to be resolved as an address difference is determined and size determining means ( ) for determining the size of the constant in each basic block according to the determined order, whereby the size of a constant to be resolved as an address difference can be estimated to be a value close to and not less than its actual size, the number of codes can be reduced, and the process speed by a linker can be improved.
