rjmccall added inline comments.
================
Comment at: clang/lib/CodeGen/CGBuilder.h:126
// FIXME: these "default-aligned" APIs should be removed,

================
Comment at: clang/lib/CodeGen/CGBuiltin.cpp:2195

- Builder.CreateDefaultAlignedLoad(IntToPtr, /*isVolatile=*/true);
+ Builder.CreateAlignedLoad(IntTy, IntToPtr, CharUnits::fromQuantity(4));
+ Load->setVolatile(true);
----------------
