[PATCH] D111497: m68k: Support bit shifts on 64-bit integers

[Sheng via Phabricator via llvm-commits]

0x59616e added a comment.

the machine ir after dag-isel (`-print-after=amdgpu-isel`) has a weird COPY:

  ...
  %12:ccrc = COPY $ccr
  ...

I believe this is the root cause.

But that COPY isn't there in the dag before dag-combine2 (`-view-dag-combine2-dags`).

I don't know where it comes from.
