* Mark C++ reference parameters as dereferenceableHal Finkel2014-07-181-1/+1
| | | | | | | | | | | | | | Because references must be initialized using some evaluated expression, they must point to something, and a callee can assume the reference parameter is dereferenceable. Taking advantage of a new attribute just added to LLVM, mark them as such. Because dereferenceability in addrspace(0) implies nonnull in the backend, we don't need both attributes. However, we need to know the size of the object to use the dereferenceable attribute, so for incomplete types we still emit only nonnull. llvm-svn: 213386

we correctly emit loads of BlockDeclRefExprs even when they don't qualify as ODR-uses. I think I'm adequately convinced that BlockDeclRefExpr can die. llvm-svn: 152479
