Ok, thanks. Even still though I would expect -instcombine (run after lsr) would do this cleanup?

...d do this cleanup? It's valid to run any IR pass after -loop-reduce. So you can try it. -gvn is probably what you're looking for. It isn't something we normally want to do. Turn off LSR if it does bad things on your target. -Andy > On Fri, Oct 19, 2012 at 2:41 PM, Andrew Trick <atrick at apple.com> wrote: > > On Oct 19, 2012, at 2:34 PM, Ryan Taylor <ryta1203 at gmail.com> wrote: > >> That solves the issue but it seems odd to me that instcombine doesn't take care of it? > > LSR is part of the backend.
