alt Hacker NewsMakes sense basically creating an easy to point out pattern for static analysis to find everything security related.
As another response pointed out, its also possible that said secret data is still in the register, which no matter what we do to the curr value could exist.
Thanks for pointing it out!

This is essentially already the case whenever you use encryption, because there are tell-tale signs you can detect (e.g., RSA S-Box). But this will make it even easier and also tip you off to critical sections that are sensitive yet don't involve encryption (e.g., secure strings).
