The code tries to follow the GDB coding style. All OR1K specific globals should have names beginning ork1_ or OR1K_. Commenting is Doxygen compatible. Much has been stripped out. See the files or1k-tdep.c, remote-or1k.c and or1k-jtag.c for details of what has changed. --------------------------------------------------------------------------*/ /*!
