[PATCH] D137791: [SDAG] bail out of mergeTruncStores() if there's an unknown store in the chain

[Jonas Paulsson via Phabricator via llvm-commits]

jonpa added a comment.

As I mentioned on the other thread, it would probably be better to derive a test case from main if possible, where the bug is exposed (64-bit overlapping store after store of 0).

Maybe stop after ISel?  Should all the unused metadata and datalaoyut string be included? (I usually strip that away for readability personally...)
