[PATCH] D143898: [CodeGenPrepare] Fold addressing mode into calls

[Eli Friedman via Phabricator via llvm-commits]

efriedma added a comment.

If I'm understanding correctly, the point is that we don't want to block folding if an address computation has multiple uses, where only some are foldable?

Expressing this in terms of "folding into a call" seems confusing and unnecessary; we should just change the logic to allow sinking if we can fold some, but not all, the uses.  (Maybe including some sort analysis of whether folding increases the number of times we perform the address computation at runtime.)
