vectorization for X86
I'm trying to vectorize a simple C code. My problem is that I don't quite understand the relationship between clang --target option and the cores mentioned in X86.td as well as other X86 related options (such as -mtune). Below are the command and the code that I'm trying to vectorize. The code compiles but I don't see any vectors. What am I doing wrong? Any help is appreciated.
