[PATCH] D60133: [DAGCombiner] Improve detection of unmergable stores, based on type size (WIP)

[Nirav Dave via Phabricator via llvm-commits]

niravd added a comment.

The current interfaces definitely do not provide anything like that. As I recall, most of the use cases requiring canMergeStoresTo involve ad hoc ways to locally declare a type/operation invalid localized to the specific target, so I suggest the just marginally expanding hte interface to capture the one issue we've seen so far (no-implict-float) and defer any deeper analysis for when we run into it.
