Understanding vectorization instruction

Hi,

Greetings from India. I need some help to understand the vectorized code produced by LLVM. Please go to the link Compiler Explorer where the LLVM Opt pipeline viewer is shown. I cannot understand the codes. Please note that along with instructions, some English text is also given in the viewer output windows. I request you to kindly provide some documents to understand it.

Thanks,
Sudakshina

Hi Sudakshina,

if I understand your question correctly then you want to know the operations the instructions perform. There is nothing LLVM specific here. My suggestion is to google for the manual from Intel, and study the instructions.
