If a loop termination compare instruction is the only use of its stride, and the compaison is against a constant value, try eliminate the stride by moving the compare instruction to another stride and change its constant operand accordingly. e.g. loop: ... v1 = v1 + 3 v2 = v2 + 1 if (v2 < 10) goto loop => loop: ... v1 = v1 + 3 if (v1 < 30) goto loop git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43336 91177308-0d34-0410-b5e6-96231b3b80d8
