  33 # If you change the directives or keywords (adding, deleting, reordering) you
  34 # need to create new tables and hash functions (directive_hash, keyword_hash).
  35 #
  36 # The following changes have been made to the generated code:
  37 #
  38 #       o prefix the names of the g, T0 and T1 arrays with 'directive_'
  39 #         resp. 'keyword_'.
  40 #
  41 #       o make the type of the tables 'const [un]signed char' (if you change
  42 #         anything make sure that the numbers fit into a char).
  43 #
  44 #       o make the hash function use the length for termination,
  45 #         not the trailing '\0', via the -l flag in emitc and some editing
  46 #         (only for directive_hash).
