When rewriting loop exit values, IndVars considers this transform not profitable if the loop instruction has a loop user which it believes cannot be optimized away. In current implementation only calls that immediately use the instruction are considered as such. This patch extends the definition of "hard" users to any side-effecting instructions (which usually cannot be optimized away from the loop) and also allows handling of not just immediate users, but use chains.
