[PATCH] D47166: use zeroinitializer for (trailing zero portion of) large array initializers more reliably

[John McCall via Phabricator via cfe-commits]

rjmccall added a comment.

I like this approach a lot.



================
Comment at: lib/CodeGen/CGExprConstant.cpp:675
+  // We have mixed types. Use a packed struct.
+  std::vector<llvm::Type *> Types;
+  Types.reserve(Elements.size());
----------------
Why std::vector?
