compiler people: how likely is it that timing-safe C code is future-proof? as in, how likely is it that future compilers will e.g. take "uint8_t diff = 0; for (size_t i=0; i<len; i++) diff |= a[i]^b[i]; return diff != 0" and put a conditional bailout jump in the loop?

It's not an unreasonable idea, but no one has actually implemented the proposed mode yet, AFAIK.

(Also I haven’t read the proposal in detail, but as described to me in a casual conversation, it wasn’t at all obvious that the guantees were strong enough.)
