Right, sorry.

--help says:

     ReleaseFast             Optimizations on, safety off
     ReleaseSafe             Optimizations on, safety on

So, maybe that.

The ReleaseSafe code looks pretty good, it generates a "jo" 
instruction: https://godbolt.org/z/cYcscf1W5

Who knows what it actually looks like in CPU microcode, though :)
