[PATCH] D49209: CodeGen: specify alignment for automatic variable initialization

[Eli Friedman via Phabricator via cfe-commits]

efriedma added inline comments.


================
Comment at: lib/CodeGen/CGDecl.cpp:902
+    Builder.CreateAlignedStore(
+        Init, Loc, Loc->getPointerAlignment(CGM.getDataLayout()), isVolatile);
     return;
----------------
llvm::Value::getPointerAlignment is not the right way to compute the alignment (it tries to guess the alignment based on the IR).  Please convert this to use a clang::CodeGen::Address instead.
