Does it have a --disable-asm or any way to suppress that idiocy at build time?
You expect that to be true; "constant-time" asm would be going out of its way to make that true...
-
-
that works out reasonably well for crypto but not if you search a data structure
-
because if you do data-dependent lookups then the only way to get guaranteed worst case is O(n) traversal
-
No, you can have an O(log n) lookup worst-case just by allowing for cache-miss every step.
-
How do you control a cache miss at a single 32-bit datum granularity?

...by avoiding optimizations that would violate it, and avoiding insns that might be var-time, faster for some inputs.
