Dan,
cmp isn't a coreutils' software - on GNU systems it's a diffutils' 
software.  Reading cmp(1) on my Linux system I see it has the same 
documentation as my BSD system, and it describes the exit codes:

     The cmp utility exits with one of the following values:

     0     The files are identical.

     1     The files are different; this includes the case where one file is
           identical to the first part of the other.  In the latter case, if
           the -s option has not been specified, cmp writes to standard output
           that EOF was reached in the shorter file (before any differences
           were found).

     >1    An error occurred.
