[Mikael Holmén via Phabricator via llvm-commits]

uabelho added a comment.

I think you're on the right track. My mir-reproducer passes with this patch, so now I get the wanted

  %6:an32_rn_pairs = COPY %5.hiAcc
  %8:an32_0_7 = COPY %6
  DBG_VALUE %8, [...]

instead of the previous

  %6:an32_rn_pairs = COPY %5.hiAcc
  %8:an32_0_7 = COPY %6
  DBG_VALUE %8.hiAcc:an32_0_7, [...]
