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