Hello. I found that llvm-diff reports difference in the same input if the source contains specific constants (or instruction). I reported this to llvm's bugzilla ( https://bugs.llvm.org/show_bug .cgi?id=33623 ), and also uploaded a patch for fix ( https://reviews.llvm.org/D34856 ). It would be great for me if somebody confirms this. I like llvm-diff. :) It helps me a lot when I'm investigating the optimized part of source code.
