Just from a style perspective, you shouldn't include C instructions that way into your language hooks. Obviously, that works, but you should better work with functions (in separate source files) and call these functions then from your language hooks. > So, if I do not reconfigure and make, the compiler will not compile the uml1.c > again, it will keep the same uml1.o (with old c instructions took from the old > text file). > Your makefile (make-lang.in) misses some dependencies. Your uml1.o rule should look like this: uml1.o: uml1.c <GCC stuff> <your_text_file_containing_instructions> ... Then uml1.o will be re-compiled once you modify your text file ... > any idea ?

Just as an example: you would create a source file for your language hooks (my_hook.c) and a source file for your C instructions doing the GENERIC stuff (my_generic.c). You'll then compile them both separately and link them together into <your_compiler>, e.g. gcc my_hook.o my_generic.o <other_stuff> -o <your_compiler> For a reference, please look at the sample front-ends you already used so far. The gcalc front-end uses the approach described above ... Hope that helps, Andi hello Andi, thanks a lot, that s exactly what I am looking for ;) Asma
