[PATCH] D70676: [DebugInfo] Don't repeatedly created undef DBG_VALUEs during machine-sinking

[Jeremy Morse via Phabricator via llvm-commits]

D71283 <https://reviews.llvm.org/D71283> Should (TM) fix it, but, the x86 test that I wrote and which seemed to replicate the issue, now no longer replicates the issue. Which is unfortunate.

Would you be able to give that patch (and its parent) a test to see whether it fixes the problem you're encountering? Storing the subregister separately should entirely fix this I believe, I'm just having problems replicating it on x86.
