Hi @NagyDonat, I can port to new and smaller tests - no problem. This was an initial, speculative PR to get the conversation going, especially for comments like this. I'll update the PR. 

I did take the cases one by one from identical-expressions.cpp to the tidy checks and noticed one pattern. It looks to me like identical expressions utilizing floats were excluded in the tidy checks but found in the static analysis check. Do you want to retain that through improvements in misc-redundant-expression, or leave that marked as FIXME? I'm happy to take a look at an improvement like that. 

Thanks! - Vince
