- *
- * This file is a modified version of 'a.out.h'.  It is to be used in all
- * all GNU tools modified to support the i80960 (or tools that operate on
- * object files created by such tools).
- *
- * All i80960 development is done in a CROSS-DEVELOPMENT environment.  I.e.,
- * object code is generated on, and executed under the direction of a symbolic
- * debugger running on, a host system.  We do not want to be subject to the
- * vagaries of which host it is or whether it supports COFF or a.out format,
- * or anything else.  We DO want to:
- *
- *	o always generate the same format object files, regardless of host.
- *
- *	o have an 'a.out' header that we can modify for our own purposes
- *	  (the 80960 is typically an embedded processor and may require
- *	  enhanced linker support that the normal a.out.h header can't
- *	  accommodate).
- *
- * As for byte-ordering, the following rules apply:
- *
- *	o Text and data that is actually downloaded to the target is always
- *	  in i80960 (little-endian) order.
- *
- *	o All other numbers (in the header, symbols, relocation directives)
- *	  are in host byte-order:  object files CANNOT be lifted from a
- *	  little-end host and used on a big-endian (or vice versa) without
- *	  modification.
- *
- *	o The downloader ('comm960') takes care to generate a pseudo-header
- *	  with correct (i80960) byte-ordering before shipping text and data
- *	  off to the NINDY monitor in the target systems.  Symbols and
- *	  relocation info are never sent to the target.

- *	
- *
- *	n_other == N_BALNAME
- *		the symbol is the 'bal' entry point to a leaf procedure.
- *		These entries result from '.leafproc' directives in which only
- *		one symbol is specified, or in which the same symbol is

- *
- *	 		NINDY INTERFACE ROUTINES
- *
- * The caller of these routines should be aware that:
- *
- * (1) ninConnect() should be called to open communications with the
- *     remote NINDY board before any of the other routines are invoked.
- *
- * (2) almost all interactions are driven by the host: nindy sends information
- *     in response to host commands.
- *
- * (3) the lone exception to (2) is the single character DLE (^P, 0x10).
- *     Receipt of a DLE from NINDY indicates that the application program
- *     running under NINDY has stopped execution and that NINDY is now
- *     available to talk to the host (all other communication received after
- *     the application has been started should be presumed to come from the
- *     application and should be passed on by the host to stdout).
- *
- * (4) the reason the application program stopped can be determined with the
- *     ninStopWhy() function.  There are three classes of stop reasons:
- *
- *	(a) the application has terminated execution.
- *	    The host should take appropriate action.
- *
- *	(b) the application had a fault or trace event.
- *	    The host should take appropriate action.
- *
- *	(c) the application wishes to make a service request (srq) of the host;
- *	    e.g., to open/close a file, read/write a file, etc.  The ninSrq()
- *	    function should be called to determine the nature of the request
- *	    and process it.

- *   REASONS WHY NINDY CAN STOP EXECUTING AN APPLICATION PROGRAM
- *
- * When NINDY stops executing an application program that was running
- * under remote host ("gdb") control, it signals the host by sending
- * a single ^P.  The host can then query as to the reason for the halt.
- * NINDY responds with two bytes of information.
- *
- * The first byte is a boolean flag that indicates whether or not
- * the application has exited.
- *
- * If the flag is true, the second byte contains the exit code.
- *
- * If the flag is false, the second byte contains a "reason for
- * stopping" code.  This file defines the possible values of that
- * code.
- *
- * There are three categories of reasons why the halt may have occurred:
- * faults, traces, and software interactions.  The first two categories
- * are processor-dependent; the values of these codes are tightly coupled
- * to the hardware and should not be changed without first examining
- * src/nindy/common/fault.c.  The software interactions involve
- * communication between NINDY and the host debugger;  their codes are
- * arbitrary.
