Abstract: We present the first version of the tool TAPENADE that can differentiate C programs. The architecture of TAPENADE was designed from the start to be language independent. We describe how this choice made adaption to C easier. In principle, it needed only a new front-end and back-end for C. However we encountered several problems, in particular related to declarations style, include files, parameter-passing mechanism, and extensive use of pointers. We describe how we addressed these problems, and how the resulting improvements also benefits to differentiation of Fortran programs.
