[PATCH] D143069: [DAGCombine] Allow DAGCombine to remove dead masked stores

[Dinar Temirbulatov via Phabricator via llvm-commits]

dtemirbulatov added a comment.

I found an error in my implementation: we could not remove the store if the chained store is a fixed type and the store we consider to remove is a scalable type, since we don't know scalable type size in the runtime. fixed.
