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

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