24 # Make object files which depend on preprocessor symbols defined in
25 # the Makefile which are not compilation options but rather configuration
26 # options dependend on the Makefile. main.c needs MAKE_VERSION while
27 # shell.c uses DEFSHELLNAME. This will cause recompilation in the case
28 # the definition is changed in the makefile. It will of course not cause
29 # recompilation if one does 'make MAKE_SHELL=csh'.

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