Compiler Optimization Report unavailable.

[gfichterpicometrix_c]

It does not seem that the icpc compiler provides vectorization optimization reports like XE Compiler does.  This is the .optrpt file, which also is shown in the Compiler Optimization Report window in Visual Studio.  Is this reporting feature unavailable by design, or is it accessed in a new way?

Hi,

Thank you for reaching out. The issue is reproducible. In Visual studio, the compiler optimization report window is empty. Optimization report generation works in command prompt. Please follow the below steps.

In Linux:

icpc -qopt-report=1 -qopt-report-phase=vec test.cpp && cat test.optrpt
icc -qopt-report=1 -qopt-report-phase=vec test.c && cat test.optrpt

In Windows:

icl -Qopt-report:1 -Qopt-report-phase:vec test.cpp && cat test.optrpt

Hope this helps.

Thanks.  I hope the Visual Studio integration will be fixed. Also, the /Qopt-report-phase:vec option is listed as available by the /Qnextgen-diag, but the option is ignored with a warning.

Could you please indicate what version of Visual Studio you are using?

With oneAPI 2021.2, it seems that Visual Studio Version 16.7.2 works fine. The bug is reproducible with Version 16.8.3.

This bug is escalated to the development team.

Hi,

The version against which you reported your issue is no longer targeted for fixes. Please check out the new versions of Intel oneAPI Toolkits for the latest features.

Thanks & Regards,
