<div>The Julia language implements sqrt(x) with conditional branch taken if x<0. Alas this prevents vectorization of loops with sqrt. Often the argument can be proven to be non-negative. E.g., sqrt(x*x+y*y). Is there an existing LLVM pass or analysis that
does floating-point range propagation to eliminate such unnecessary checks?</div>
