-! This file was generated by a compiler that is currently not part of the CBE
-! as the CBE compiler does not generate code for the T4 architecture. If
-! such a compiler (e.g. the Oracle Studio 12.3) becomes part of the CBE
-! the longest_match.o file can simply be comp[iled from longest_match.c
-! as for the 32-bit version, no modifications were made.
