-/* Copyright 1992 Free Software Foundation, Inc.
- *
- * 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.

-/* MEANING OF 'n_other'
- *
- * If non-zero, the 'n_other' fields indicates either a leaf procedure or
- * a system procedure, as follows:
- *
- * 1 <= n_other <= 32 :
- * The symbol is the entry point to a system procedure.
- * 'n_value' is the address of the entry, as for any other
- * procedure. The system procedure number (which can be used in
- * a 'calls' instruction) is (n_other-1). These entries come from
- * '.sysproc' directives.
- *
- * n_other == N_CALLNAME
- * the symbol is the 'call' entry point to a leaf procedure.
- * The *next* symbol in the symbol table must be the corresponding
- * 'bal' entry point to the procedure (see following). These
- * entries come from '.leafproc' directives in which two different
- * symbols are specified (the first one is represented here).
- *
- *
- * 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
- * specified twice.
- *
- * Note that an N_CALLNAME entry *must* have a corresponding N_BALNAME entry,
- * but not every N_BALNAME entry must have an N_CALLNAME entry.
