Can anyone please provide the equivalent to the gcc flag "-ftree-vectorizer-verbose=6" but using icc?
Basically I want to see during compilation which loops are not vectorized and why.
Many TIA,Best regards,Giovanni
did you try -vec-report[n] where n is a value denoting which diagnostic messages to report. Possible values are:
So, -vec-report4 or -vec-report5 might be what you want. Please let us know whether it's suitable for you.
Thank you. That's exactly what I was looking for.
The underlying problem I trying to solve is well 1) see what loops are not being vectorized but also would like to provide a very generic interface for sorting (similar to those in ) but without losing vectorization possibilities. I started the question on this via StackOverflow: http://stackoverflow.com/questions/11614758/special-sorting-algorithm-and-generic-signature
