Hi Hal, In that case what is the best way to query whether there is a loop carried dependence between B[j] and A[j] at i-loop level? We were operating under the assumption of 'conservatively correct' behavior of alias analysis in the function scope?

I'll see if I can reproduce it outside our setup. Does it depend on machine architecture? I generally use x86... regards,   Fedor. > > Thanks.

I don't exactly remember when I last tried it and I didn't realize there was r342896. I'll check it out. Thanks.

I had a chance to try -print-after-all with NPM. It seems like there's still no output for the passes before objc-arc-contract (which is basically what I saw before.) Does anyone else see this? Are we talking about the same thing? *** IR Dump After ObjC ARC contraction *** *** IR Dump After Pre-ISel Intrinsic Lowering *** *** IR Dump After Expand Atomic instructions *** *** IR Dump After

-print-after-all is very useful for debugging and learning about LLVM. I would hope that would be implemented for the new PM before removing the old PM. I'd personally consider it a blocker. -Troy > -----Original Message----- > From: llvm-dev <llvm-dev-bounces at lists.llvm.org> On Behalf Of Eric Christopher > via llvm-dev > Sent: Tuesday, July 09, 2019 7:40 PM > To:

My understanding is that alias analysis returns results in the function scope, not in loop scope. Since both the phis access both global arrays, that should results in BasicAA conservatively returning MayAlias. I debugged this a little bit and narrowed it down to the section of the code in BasicAAResult::aliasPHI() which has this comment- // Analyse the PHIs' inputs under the assumption

I mentioned this earlier in the thread - I would like to see something like D41574 in the optimizer. It's optimizing code that no other pass does currently, and I don't see any other near-term proposal that gets us those optimizations. Omer, can you rebase that to trunk? I think a header has moved, so it doesn't build as-is. I'd like to know if it can catch the cases in D45842. If

Hi Hiroshi, Thanks for that. I find “rebase” difficult to use. Maybe I don’t understand it, but it always causes a lot ‘conflicts’ that are very hard to fix according to my experience. I have another question though. LLVM requires that reviewed patches are pushed as a /single/ commit with a standardised message, particularly specifying the Differential Revision url as part of the commit message.

@Zola, Eric, I really feel the communication and reasoning here is problematic. From my perspective, you removed stuff "we don't need", ignoring whether it is used, and then let people figure out how to deal with the result. What I most dislike about the process most is how questions and concerns are then ignored or played down. Thanks,   Johannes On 5/12/20 2:10 PM,

Overall seems fine to me.
