The passed arguments must fit to the new interface.
This is what Coccinelle is supposed to help you do. The difficulty is indeed if the parameters and return types change. In that case, you have to figure out what the new arguments and the new calling context should be, just as if you were to make the change by hand. If there is a systematic way to make the adjustements, then Coccinelle can help you. For example, one might want to do: @@ expression E; @@ - foo(E) + bar(E->x,0) But there is no general rule for all problems. If the arguments are computed in completely random ways, and the context uses the return value in completely random ways, then Coccinelle is probably not very useful. You could do as well by grepping for the function name and changing each instance by hand. julia _______________________________________________ Cocci mailing list [email protected] http://lists.diku.dk/mailman/listinfo/cocci (Web access from inside DIKUs LAN only)
