The GCC Cobol compiler now executes MOVE NumericDisplay TO COMP-3 statements more quickly. This speedup comes from introducing a specialized mh_numdisp_to_packed function in move.cc and enabling __gg__char_national in parse.y. The change improves the efficiency of converting character-based numeric data to a packed-decimal format, a common operation in Cobol programs.
