[LLVMdev] [RFC] Adding functions for unaligned load/store to Support for JIT/RuntimeDyld
Hi, I've noticed that certain parts of LLVM (RuntimeDyld, JIT) use unaligned memory accesses to load/store pointers or just 32- or 64-bit integers. Technically, this is undefined behavior, and UBSan reports errors when this happens. Even if we believe we're running some x86-specific code (e.g. RuntimeDyldELF::resolveX86_64Relocation) what matters for unaligned acceses in source code is
