Using HLO
In conjunction with the vectorization options, -Qax{K|W|N|B|P} and -Qx{K|W|N|B|P}, for Pentium III and later processors, this option causes the compiler to perform more aggressive data dependency analysis than for -O2. This may result in longer compilation times. Exampleprompt>icl -O3 -QaxW myprog.cpp |
