[PATCH] D83667: [ARM] Fix IT block generation after Thumb2SizeReduce with -Oz

[Dave Green via Phabricator via llvm-commits]

Thanks. It's hard to tell in all that where the problem might be, there are quite a few changes in all! And I didn't spot anything obvious by eyeballing it.

Is it possible to reproduce the original? Into a program that we can run ideally, and start figuring out where the problem in it is? Or would that still be a lot of steps?

If we are confident that this is the commit causing the problem (and it sounds like we are) then we can revert in the meantime. But we do need some way of starting to figure out how to fix it :)
