- I/O Library. This file has compiler specifics for GCC as there is no
- ANSI C standard for doing IO.
-
- GCC - uses EFIAPI assembler. __asm__ calls GAS. __volatile__ makes sure the
- compiler puts the assembler in this exact location. The complex GNUC
- operations are not optimzed. It would be possible to also write these
- with EFIAPI assembler.
-
- We don't advocate putting compiler specifics in libraries or drivers but there
- is no other way to make this work.
