[lldb-dev] lldb remote protocol

Well, it didn't take too long to run into issues:
Assertion failed: (byte_order == m_host_arch.GetByteOrder()), function GetHostInfo, file /Users/felix/Projets/oss/lldb/source/Plugins/Process/gdb-remote/GDBRemoteCommunicationClient.cpp, line 1235.
Abort trap: 6
Is that something no one did because it's gonna be hard and deep-reaching or because nobody had a use case for it?
Also, pretty early (shortly after receiving no information for qProcessInfo and qShlibInfoAddr), lldb asks for the 512 bytes located at 0xffff0000. What is it trying to accomplish?
That's where I stopped today. I might bug you guys again tomorrow :)

GDB documents its communication protocol, but I'm not a fan of how every concern happens at the same level (especially reliability), so I was hoping the LLDB protocol could be more modern.
