...etc. I pushed back one fix for sccp, and will post one for adce later. Hopefully they will help in your case, but I doubt they are exhaustive. FWIW, there is one bright spot here: I have no (not yet…) example where incorrect code is generated. -Gerolf > On May 31, 2019, at 2:08 AM, Gerolf Hoflehner via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > > There is a non-deterministic problem with the uselists.

...ther location doesn't reach a global, I think it would be much more effective to re-cast this as a forward analysis that determines all the memory locations in a function that come from outside the function, and use that to drive the no-alias responses.

Can you share you compile-time and memory footprint measurements at least for CTMark? For a new pass/feature it would be great to share this with the community before you commit. Or did I miss them?

...e struct before reading part of 't'. If we could mark only the source as volatile then we could discard the stores to 't'. Again - nobody has asked for this, but if there's interest now would be a good time to look at it. Cheers, Lang.
