We were checking for negatives even when that can't be. And we are doing this dance of int64_t x, y; uint64_t a, b; x = a; b = y; This is always confusing and not always right. > The thing is we're removing some code trying to > detect negative which seems to be still helpful to detect e.g. overflows > (even though I don't think it'll happen).

If you grep through the code, you see that half of the things are int64_t and the other half is uint64_t. I find it always confusing. > I've reviewed all the rest patches and all look good here. Thanks very much.
