Hi, I am optimizing an application. I am facing the below warning message in xxx.optrpt file.
(I gave -qopt-report=5 option.)
remark #25461: Imperfect Loop Unroll-Jammed by 2 (pre-vector)
What would be the general requirements of perfect loop unroll-jamming?
I don't see any kinds of explanations about this warning in icc reference manual.
Also, what is the meaning of (pre-vector)?
I am using icc 15.0.2 and unfortunately, I cannot upload the code here because it is very complex and large code.
