  24 # Directive and keyword tables. We use hash tables. These hash tables have been
  25 # generated with mph which can be found in pkgsrc/devel/mph.
  26 # If you change the directives or keywords (adding, deleting, reordering) you
  27 # need to create new tables and hash functions (directive_hash, keyword_hash).
  28 #
  29 # The following changes have been made to the generated code:
  30 #
  31 #       o prefix the names of the g, T0 and T1 arrays with 'directive_'
  32 #         resp. 'keyword_'.
  33 #
  34 #       o make the type of the tables 'const [un]signed char' (if you change
  35 #         anything make sure that the numbers fit into a char).
  36 #
  37 #       o make the hash function use the length for termination,
  38 #         not the trailing '\0', via the -l flag in emitc and some editing
  39 #         (only for directive_hash).
