[LLVMdev] Loop vectorizer behaviour for 2D arrays and parallel annotation
Hello, I am trying to vectorize the following loop but the vectorizer says: "Found a possible write-write reorder" and does not vectorize. Why? for (j=0; j < 8; j++) { jj = j << 3; m2[j][0] = diff[jj ] + diff[jj+4]; m2[j][1] = diff[jj+1] + diff[jj+5]; m2[j][2] = diff[jj+2] + diff[jj+6]; m2[j][3] = diff[jj+3] + diff[jj+7]; m2[j][4] = diff[jj ] -
