-! 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), and
-! then it was modified by hand to remove some unnecessary instructions that
-! the compiler generated and the main loop's branches was rearranged for
-! fewer taken branches on the most frequent code path. These modifications
-! were made in 7 steps. In each step, a few lines were removed from and added
-! to the compiler generated code to produce an equivalent binary. The lines
-! that were removed in step <i> are marked by "!<i>" at the beginning of the
-! line, the lines added in this step are marked by the same added at the end of
-! the line. In other words, let C_i mean the code, after step <i> (C_0 is
-! the original, compiler generated code, C_7 is the code in this file)
-! To reproduce C_i (0 <= i < 7) first take C_<i+1>, remove the lines that
-! end in !<i+1>, and then remove the !<i+1> string from the beginning of those
-! lines that start with it. Comparing C_i and C_<i+1> is a simple task, as
-! only a few lines have changed.
-! If a compiler (e.g. the Oracle Studio 12.3) becomes part of the CBE and
-! it will be able to generate as efficient code as in this file the
-! longest_match.o file can simply be comp[iled from longest_match.c .
