[PATCH] D49771: CodeGen: use non-zero memset when possible for automatic variables

[Joerg Sonnenberger via Phabricator via cfe-commits]

joerg added a comment.

There are two different considerations here:
(1) Create less target code
(2) Create less IR

If this code can significantly reduce the amount of IR, it can be useful in general. That's why the existing memset logic is helpful.
