[csmith-dev] Generate two slightly different files


I'm currently searching for a tool to generate two C files that
are very similar. What do I mean by similar? The respective AST of the C
files should only differ in one subexpression/type/etc. The difference
should mimic the changes a developer does between two compiler

Does csmith already allow such small alterations of its output? If so, I
haven't seen an command line option for it. If it doesn't have this
feature, could you give me a small hint where I should look to implement
this behavior?
