[llvm-dev] Loop Access Analysis

[Shraiysh Vaishay via llvm-dev]

Hi all,

Just putting this here in case someone else stumbles upon this.

So, it looks like it is important to rotate the loop for the pass to run
properly. Running `-passes="function(mem2reg,loop(rotate))"` started
displaying proper analysis.
A related issue was mentioned earlier [here](

Regards,
Shraiysh
