Hi, @GrigoriyNovitskiy, thanks for taking on this issue.

A core functionality of llvm-snippy is the ability to dump the initial state of registers. This can be useful if you are setting this state before the snippet via some external code.

Please try running llvm-snippy as described in the ticket. You should not see a file with the initial register states. This is the problem. Now, please try to fix it.
