Show verbose parallelization messages.
As the compiler analyzes loops explicitly marked for parallelization with directives, it issues warning messages about certain data dependencies it detects; but the loop will still be parallelized.
Use with -xopenmp and OpenMP API directives.
Warnings are issued with the compiler detects the following situations:
Problematic use of OpenMP data sharing attributes clauses, such as declaring a variable shared whose accesses in an OpenMP parallel region may cause data race, or declaring a variable private whose value in a parallel region is used after the parallel region.
No warnings appear if all parallelization directives are processed without issues.
Sun Studio compilers support the OpenMP API parallelization model. Consequently, legacy C$MIC parallelization directives are deprecated and ignored. See the OpenMP API User’s Guide for information on migrating to the OpenMP API.
