Relax unaligned access assertion when type is byte aligned Summary: This relaxes an assertion inside SelectionDAGBuilder which is overly restrictive on targets which have no concept of alignment (such as AVR). In these architectures, all types are aligned to 8-bits. After this, LLVM will only assert that accesses are aligned on targets which actually require alignment. This patch follows from a discussion on llvm-dev a few months ago http://llvm.1065342.n5.nabble.com/llvm-dev-Unaligned-atomic-load-store-td112815.html Reviewers: bogner, nemanjai, joerg, efriedma Reviewed By: efriedma Subscribers: efriedma, cactus, llvm-commits Differential Revision: https://reviews.llvm.org/D39946 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@320243 91177308-0d34-0410-b5e6-96231b3b80d8
