02:47 < elichai2> Hi, I'm not trying to be pedantic here just to understand C better :). here `n` can be a negative signed integer, isn't bitwise shifting implementation defined on negative numbers? https://github.com/bitcoin-core/secp256k1/blob/master/src/ecmult_const_impl.h#L19
02:48 < elichai2> (`n` in this macro is a int from the `wnaf_1` array, which ` *  - each wnaf[i] an odd integer between -(1 << w) and (1 << w)`)
10:51 < sipa> elichai2: i think you're right
10:51 < sipa> and we're just doing it to get the sign bit
10:51 < sipa> i think this can also be done by first converting to unsigned (which is well-defined iirc) and then doing the same operation
