[PATCH] D88893: [SROA] Only generate memcpy if the slices is large 'enough' (WIP).

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

This isn't really SROA specific is it?
Instcombine also expands small (16 bytes, hardcoded) memcpy's
I would think this should be done by some standalone pass, as a costmodel-driven optimization.
