Dear LLVM Developers, My name is Artem Vopilov, I am a student at TU Darmstadt. I am writing to you to ask about Alias Analysis. I am using llvm to analyze alias between variables in programs. I am using Alias Analysis implemented in llvm with command "opt -analyze -aa-eval -print-all-alias-modref-info" and for printing sets of alias "opt -analyze -aa-eval -print-alias-sets".

So, i'm working through the last of miniscule gvn optimizations, and one of the things that gets tested is whether it will eliminate non-volatile loads in favor of ohter non-volatile loads when there are volatile loads in the way. I.E. define i32 @test1(i32* nocapture %p, i32* nocapture %q) { entry: %x = load i32, i32* %p %0 = load volatile i32, i32* %q %y = load i32, i32* %p %add =
