I'm trying to fix that bug: https://llvm.org/bugs/show_bug.cgi?id=20049
It turns out this is the kind of optimization that I really need, as when
it isn't done, all kind of other optimizations opportunities down the road
are not realized as they are not exposed.
I have no idea where to start digging for this. I assume there is some kind
of interaction between memory dependency and alias analysis that is overly
conservative. Can someone gives me some infos on how the 2 interact
together ? What is the code that is supposed to remove these kind of loads ?
