Here is the paste of IR after each pass http://pastebin.com/42xLT4ZN I've annotated 3 spots in the code with stars. In (1), after unreachableblockelim, addr89 is precomputed outside the loop once and is used in store in (2). However, in (3), after codegenprepare, there is now a bunch of math being done every loop iteration to get the address for the same store. Additionally, looks like the same thing is happening for several addresses above as well. Doe...
