--- Comment #22 from Tom Stellard tstellar@gmail.com --- Created attachment 113709 --> https://bugs.freedesktop.org/attachment.cgi?id=113709&action=edit Patch to re-enable subreg liveness
I think this bug has been fixed. This patch re-enables subreg livess. Can you see if the issue still exists with this patch applied to LLVM git.
