--- Comment #3 from Cong Hou <congh at google dot com> --- How do you generate the final operations in vectorized code? I just submitted a patch on this issue. The patch supports non-isomorphic operations with the restriction that all operations on even/odd elements still be isomorphic. Please give me the comment on this patch. Thank you! Cong
