Re: [PATCH v2 0/1] MR1065: ntdll: Add CFI unwind info to __wine_syscall_dispatcher (x86_64)

[Kevin Puetz (＠puetzk)]

I haven't reviewed the actual changes here yet (and I'm not that knowledgeable on CFI either), but I would like to vote that this would be a huge quality-of-life improvement for us. When your app is also winelib (since it has dependencies on both win32 and other system ELF libraries), we almost exclusively end up debugging with a unix debugger, and the fact that backtraces almost always fail at `__wine_syscall_dispatcher` is a big pain. Using `gdb record` so we can rewind to see where the call came from helps, but can't help if all you have is a coredump. So this is would be greatly appreciated. Enough so that I had actually written myself a task to try and teach myself enough about DWARF well enough to try writing it :-)
