You can take unoptimized bitcode and run it through ‘opt’ to have complete flexibility in which passes get run. It may take some fiddling to find out the pass sequence and ordering that does what you want, as some passes rely on previous passes to canonicaplize code into a form it can effectively work with. -Jim On Apr 10, 2013, at 5:39 PM, Anadi Mishra <reachanadi at gmail.com> wrote:

Hello, I am trying out the LoopVectorizer(LV) pass and would like to decouple it from O3 which is currently required to run LV. I want to do this because I want to understand the behaviour of LV by trying simple loops but the O3 mostly optimises away the loop body. Any ideas would be appreciated. Best, Anadi. -------------- next part -------------- An HTML attachment was scrubbed... URL:
