!

! 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 .
