Suppressing vectorization remarks

Intel C++ 15.0 (Update 1) is spitting out many vectorization remarks of this form:

remark: loops in this subroutine are not good vectorization candidates (try compiling with O3 and/or IPO)

when I do builds for profiling with these options: 

icl /nologo /Qstd=c++11 /Qcxx-features /Wall /Wp64 /Qdiag-disable:177,869,1786,2259,3280,10382,11074,11075 /QxHOST /DNOMINMAX /DWIN3
2_LEAN_AND_MEAN /DNDEBUG /Qansi-alias /O3 /fp:fast /Qprec-div- /Qip /Z7 /c /object:myfile.obj myfile.cc

There are a number of problems with this:

  • The remark has no diagnostic number so I can't suppress it
  • am compiling with /O3
  • This is C++ so it doesn't have "subroutines" ;-)

Does anyone know how to suppress these? Is this something Intel needs to fix?

Thanks!

Hi,

Thanks for reporting your issue. You can try suppressing with help of Qdiag-disable:vec or /Qopt-report-file:filename options and this problem is already brought into our notice and it will be fixed in 15.0 update2.

Thanks,

Reddy
