[PATCH 1/8] Add basic Coccinelle transforms.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Coccinelle (http://coccinelle.lip6.fr/) is a program which performs
mechanical transformations on C programs using semantic patches.  These
semantic patches can be used to implement automatic refactoring and
maintenance tasks.

Add a set of basic semantic patches to convert common patterns related
to the struct object_id transformation.
