I recently updated to Visual Studio 2015 Update 3, which has improved its diagnostics. As a result of this, LLDB is uncompilable due to a slew of errors of the following nature:
D:\src\llvm\tools\lldb\include\lldb/Target/Process.h(3256): error C2719: 'default_stop_addr': formal parameter with requested alignment of 8 won't be aligned The issue comes down to the fact that lldb::Address contains a std::atomic<uint64_t>, and is being passed by value pervasively throughout the codebase. There is no way to guarantee that this value is 8 byte aligned. This has always been a bug, but until now the compiler just hasn't been reporting it. Someone correct me if I'm wrong, but I believe this is a problem on any 32-bit platform, and MSVC is just the only one erroring. I'm not really sure what to do about this. Passing std::atomic<uint64>'s by value seems wrong to me. Looking at the code, I don't even know why it needs to be atomic. It's not even being used safely. We'll have a single function write the value and later read the value, even though it could have been used in the meantime. Maybe what is really intended is a mutex. Or maybe it doesn't need to be atomic in the first place. Does anyone have a suggestion on what to do about this? I'm currently blocked on this as I can't compile LLDB.
