This must have happened during a refactor or something, but since we're
making a copy of the function pointers, it would have only gotten the
version /prior/ to loading host VDSO symbols.
Moves the VDSO thunk definition setting to the end after VDSO symbol
definitions in order to get host VDSO symbols working again.
These are a Linux construct and should live here. Removes a weird
passthrough API from FEXCore and keeps it in the frontend instead.
This isn't even typically allocated in a real setup, as it's only a
fallback for if VDSO isn't loaded.
The CallbackReturn function stays in FEXCore because it would have
caused an API in the other direction instead.
This causes a global initializer that registers an atexit handler.
Be smarter, use an std::array and pass its data around using a span
instead.
Removes the global initializer and removes the atexit installation
ARM64, x86 (64-bit), and x86 (32-bit) each have different alignment
requirements, so this change ensures that consistent data layout is
used for packing and unpacking.
Which requires moving LinuxEmulation to its own independent folder as
well. Since both IRLoader and FEXLoader rely on it.
No functional change, just moves the the code around.
