unsigned HOST_WIDEST_INT n

Detailed Description

   A symbolic number is used to detect byte permutation and selection
   patterns.  Therefore the field N contains an artificial number
   consisting of byte size markers:

   0    - byte has the value 0
   1..size - byte contains the content of the byte
   number indexed with that value minus one
