Notably, xcb_take_socket uses the callback_guest annotation, since the
given callback is never called on the host (instead it's manually forwarded
back to a helper guest thread for calling).
This could also prove useful for guest libraries, however the implicit
dependency of libEGL on libGL (via glXGetProcAddress) cannot be resolved
easily with the current build setup.
Keeping this in the commit history to go back to later.
While these are required for static-pie builds to work, with the glibc
bug we can't use those yet.
Disable for now since it is is unnecessary.
Instead of searching inside the thunk folder for Guest and Host files
with a library name attached to it, also search for ones That are just
named `Host.cpp` and `Guest.cpp`.
Makes quickly pounding out a bunch of thunks significantly less tedious.
This is necessary for building FEX packages that contain some initial thunk libs.
Gives an initial foothold for a default location for the host and guest thunk folders
This interface is for native host code to be able to call back in to JIT
to execute guest code.
This is mainly for thunks but could be used for other purposes.
This can cross a couple ABI boundaries so one must be careful when
calling in to this
