Hi Richard:
I have a question. I don't understand the purpose of adding
'-fno-tree-vectorize' here.
I don't think -fno-tree-vectorize will make a difference here. This
test case uses __attribute__((vector_size(...))) explicitly so the
vector operation will be used even if -fno-tree-vectorize.
Yes, I did the test and compared the intermediate results and saw no
difference.
“remove the vect_* stuff”，I don’t quite understand what it means either.:-(
