I've recently begun exploring bare-metal development in Ada, with some grea=
t successes targeting bare-metal ARM using AdaCore's GPL compiler. I have s=
ome minimal experience with bare-metal x86 development, and would like to u=
se Ada for this purpose. I was wondering what the best way to create an x86=
 bare-metal toolchain is.
I've seen Lucretia's 'Ada Bare Bones' tutorial on osdev.org, which provides=
 some useful information about building the runtime. This is quite straight=
forward, but I'm a little unsure about how to build the cross compiler for =
the task.
Am I correct in my assumption that creating a 'freestanding' binary is done=
 by compiling with the right kind of RTS? If I were to create/utilise a pro=
per freestanding RTS, would it be suitable to use either the AdaCore or FSF=
 GNAT targeting x86?
Any help understanding this would be greatly appreciated.
