[PATCH] D28167: Create as few pieces of an argument as possible when promoting an argument.

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

I'm sure there's some obscure reason for this phase ordering. Do we run instcombine before argument promotion? We should turn these FCA loads into GEPs, loads, and insertelements. FCA loads are currently non-canonical, although it is reasonable for a frontend to generate them.
