Chris Lattner 2351abaeab Move from Stage 0 to Stage 1. ... Only emit one PHI node for IV uses with identical bases and strides (after moving foldable immediates to the load/store instruction). This implements LoopStrengthReduce/dont_insert_redundant_ops.ll, allowing us to generate this PPC code for test1: or r30, r3, r3 .LBB_test1_1: ; Loop li r2, 0 stw r2, 0(r30) stw r2, 4(r30) bl L_pred$stub addi r30, r30, 8 cmplwi cr0, r3, 0 bne .LBB_test1_1 ; Loop instead of this code: or r30, r3, r3 or r29, r3, r3 .LBB_test1_1: ; Loop li r2, 0 stw r2, 0(r29) stw r2, 4(r30) bl L_pred$stub addi r30, r30, 8 ;; Two iv's with step of 8 addi r29, r29, 8 cmplwi cr0, r3, 0 bne .LBB_test1_1 ; Loop git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22635 91177308-0d34-0410-b5e6-96231b3b80d8		2005-08-03 22:51:21 +00:00
