delta/cpython-git.git/Modules/_operator.c, branch v3.7.13 github.com: python/cpython.git bpo-40791: Make compare_digest more constant-time. (GH-23438) 2020-11-22T17:33:09+00:00 Miss Islington (bot) 31488909+miss-islington@users.noreply.github.com 2020-11-22T17:33:09+00:00 db95802bdfac4d13db3e2a391ec7b9e2f8d92dbe The existing volatile `left`/`right` pointers guarantee that the reads will all occur, but does not guarantee that they will be _used_. So a compiler can still short-circuit the loop, saving e.g. the overhead of doing the xors and especially the overhead of the data dependency between `result` and the reads. That would change performance depending on where the first unequal byte occurs. This change removes that optimization. (This is change GH-1 from https://bugs.python.org/issue40791 .) (cherry picked from commit 31729366e2bc09632e78f3896dbce0ae64914f28) Co-authored-by: Devin Jeanpierre <jeanpierreda@google.com>
