Instead of having the configuration being loaded and stored in to a
frontend system. First moves the backing store of the configuration in
to FEXCore.
Each layer that is constructed then loads its particular configuration.
After the layers are loaded, then a meta layer is constructed that
merges the layers flat.
This means we will no longer hit the problem where a configuration is
stored in the "main" configuration file, then environment and arguments
passed manage to overwrite it.
The order of the layers going from inner most layer to outer most, with
outermost overwriting previous layer configurations is as follows:
Main < Global application < Local application < Arguments < Environment
One step that needs to be changed in the future is that FEXCore can then
just load its configuration from the layers directly since the data is
in FEXCore now. This will be reserved for a future change so we are less
disruptive.
The Passmanager passes need very little or zero x86 knowledge to do
their work. They don't need the x86 OpDispatcher handling code at all.
Convert this entirely over to using the IREmitter class so it can
actually optimize IR code from the IRLoader frontend
This application loads an IR from an IR file.
It then proceeds to lex the file and translate it to binary IR.
Once the file is loaded it then the IR is passed off to the backend and
it attempts to run the IR.
This will be used when debugging RA and writing unit tests directly in
IR.
This is a necessary evil for ensuring correctness
