[cfe-dev] CopyPaste detection clang static analyzer

[Vassil Vassilev]

Thanks for the pointers!
We have a lot of copy-pastes in our framework (with minor changes: the 
for loop became a while loop and so on). I was thinking to submit a GSoC 
proposal for copy-paste detection and maybe to extend it to semantic 
detection where possible. Would the static analyzer be a good platform 
for the students to implement such a feature? Would it be beneficial for 
the analyzer?

You can test this support by building from trunk and enabling the checker alpha.core.IdenticalExpr. The people working on this are Daniel Fahlgren, Anders Rönnholm, and Per Viberg.
