hello, i am trying to optimize omp simd loop as follows int main(int argc, char **argv) { const int size = 1000000; float a[size], b[size],c[size]; #pragma omp simd for (int i=0; i<size; ++i) { c[i]= a[i] + b[i]; } return 0; } i run it using the following command; g++ -O0 --std=c++14 -fopenmp-simd lab.cpp -Iinclude -S -o lab.s

...same assembly. Why is that so? why not omp simd is more >> efficient? >> >> Please help >> >> >> -- > ~Craig > -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20171231/9687fe24/attachment.html>
