How OPTIMIX can generate code for foreign frontends and intermediate representations

(only for C-mode)

If the nodes of the intermediate representation are not allocated by AST nor fSDL functions, but with frontends that use their own node types, several function calls in the generated code have to be adapted to the foreign representation.

If the user wants to use foreign node representations, has to do the following:

• call optimix with option -graphnode <GRAPHNODE> where GRAPHNODE is the name of the node type that is used in the foreign representation. This inserts an include statement in the body of the generated file for the header <GRAPHNODE>.h. In this header the user has to map certain macros which are used in the generated code, to its representation.
• The list of macros is found in the header pattern file $OPTIMIXDIR/include/GRAPHNODE.h, and in appendix 7.3.
• In AST mode, the node type is tTree from AST intermediate representations. When the user generates other tree names with AST, also apply this procedure.
