Haicheng Wu 9e87f080cd [CVP] Convert an SDiv to a UDiv if both operands are known to be nonnegative ... The motivating example is this for (j = n; j > 1; j = i) { i = j / 2; } The signed division is safely to be changed to an unsigned division (j is known to be larger than 1 from the loop guard) and later turned into a single shift without considering the sign bit. llvm-svn: 263406		2016-03-14 03:24:28 +00:00
