Dear all, Hi! Recently, I try to combine the passes SeparateConstOffsetFromGEP and LoopStrengthReduction to transform the multiplication in the lowered GEP IRs into addition. However, it seems LoopStrengthReduction is unable to remove all the multiplications for the element offset calculation. My test code is shown below and thanks a lot in advance for your time and...

Hi, I want to improve the way CGP sinks the incoming values of a PHI node towards memory accesses. Improving it means a lot to some of our key benchmarks, and I believe can benefit many general cases as well. CGP's OptimizeMemoryInst function handles PHI nodes by running AddressingModeMatcher on all incoming values to see whether they reach consensus on the addressing mode. It does a
