HPO Vectorizer Report

[Jamil_A_]

 Hi 

    I am using the following flags to track SIMD vectorisation

     -opt-report2 -opt-report-phase=hpo

     Is there a flag that will demangle the output from the Vectorizer report.  Example output below.

 Thanks

 Jamil

Jamil, since you're particularly interested in vectorization per-se, you can actually use the option "-vec-report" where n controls the degree of reporting (you can check details using "icc -help reports |more") and use the -opt-report-file= to dump out the info into a file. You can gradually increase the value of n depending on what you need in the report (start with n=2 which will dump vectorized/non-vectorized loops) _kittur

Jamil, were you satisfied with the output with the suggested option earlier?
