[Nikita Popov via Phabricator via llvm-commits]

nikic added inline comments.

 ;
   %sub = add <2 x i8> %x, <i8 -5, i8 -5>
   %c1 = icmp eq <2 x i8> %x, <i8 5, i8 undef>
----------------
We should also have the variant with the undef on the `add`. Handling that one would need m_SpecificIntAllowUndef() as well.
