# Directive table. We use a hash table. This hash table has been
# generated with mph which can be found on the usual GNU mirrors.
# If you change the directives (adding, deleting, reordering) you
# need to create a new table and hash function (directive_hash).
#
# The following changes have been made to the generated code:
#
#	o prefix the names of the g, T0 and T1 arrays with 'directive_'.
#
#	o make the type of the tables 'const [un]signed char' (if you change
#	  anything make sure that the numbers fit into a char).
#
#	o make the hash function use the length for termination,
#	  not the trailing '\0', via the -l flag in emitc and some editing.
