mainly involves blocking code under __MINGW32__ and some updates to the
various CMakeLists.txt and AddLLDB.cmake module files
Some functions are missing in MinGW implementations (like gets_s and others
:/)

I got lldb-server to compile and run on Windows, however, it crashes
immediately and the backtrace shows this:
0 0x0000000000724615
lldb_private::NativeProcessProtocol::Launch(lldb_private::ProcessLaunchInfo&,
lldb_private::NativeProcessProtocol::NativeDelegate&,
lldb_private::MainLoopBase&,
std::shared_ptr<lldb_private::NativeProcessProtocol>&)
1 0x00000000005f815d
lldb_private::process_gdb_remote::GDBRemoteCommunicationServerLLGS::LaunchProcess()
2 0x00000000004020e5
handle_launch(lldb_private::process_gdb_remote::GDBRemoteCommunicationServerLLGS&,
int, char const* const*)
3 0x000000000040335e main_gdbserver(int, char**)
4 0x000000000188329c main
I had to #ifndef __MINGW32__ around lldb-platform.cpp as it contains too
much Linux code that can not be compiled under Windows (fork, exec*)
and basically lldb-server calls the main_gdbserver instead of main_platform
function
Looking at the function that crashes, I see this:
llvm_unreachable("Platform has no NativeProcessProtocol support");
Any ideas?
Thanks!
issues after that as well, since you're the first person afaik to try
