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