GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

/* ANSI and traditional C compatibility macros
ANSI C is assumed if __STDC__ is #defined.
Macro ANSI C definition Traditional C definition
----- ---- - ---------- ----------- - ----------
PTR `void *' `char *'
LONG_DOUBLE `long double' `double'
VOLATILE `volatile' `'
SIGNED `signed' `'
PTRCONST `void *const' `char *'
ANSI_PROTOTYPES 1 not defined
CONST is also defined, but is obsolete. Just use const.
obsolete -- DEFUN (name, arglist, args)
Defines function NAME.
ARGLIST lists the arguments, separated by commas and enclosed in
parentheses. ARGLIST becomes the argument list in traditional C.
ARGS list the arguments with their types. It becomes a prototype in
ANSI C, and the type declarations in traditional C. Arguments should
be separated with `AND'. For functions with a variable number of
arguments, the last thing listed should be `DOTS'.
obsolete -- DEFUN_VOID (name)
Defines a function NAME, which takes no arguments.
obsolete -- EXFUN (name, (prototype)) -- obsolete.
Replaced by PARAMS. Do not use; will disappear someday soon.
Was used in external function declarations.
In ANSI C it is `NAME PROTOTYPE' (so PROTOTYPE should be enclosed in
parentheses). In traditional C it is `NAME()'.
For a function that takes no arguments, PROTOTYPE should be `(void)'.
obsolete -- PROTO (type, name, (prototype) -- obsolete.
This one has also been replaced by PARAMS. Do not use.
PARAMS ((args))
We could use the EXFUN macro to handle prototype declarations, but
the name is misleading and the result is ugly. So we just define a
simple macro to handle the parameter lists, as in:
static int foo PARAMS ((int, char));
This produces: `static int foo();' or `static int foo (int, char);'
EXFUN would have done it like this:
static int EXFUN (foo, (int, char));
but the function is not external...and it's hard to visually parse
the function name out of the mess. EXFUN should be considered
obsolete; new code should be written to use PARAMS.
DOTS is also obsolete.
Examples:
extern int printf PARAMS ((const char *format, ...));

the entry point is less than EXEC_BYTES_SIZE into a page (e.g. page
aligned)): (padding is needed so that text can start at a page boundary)
start at TEXT_START_ADDR, offset TARGET_PAGE_SIZE, size as stated.
Specific configurations may want to hardwire N_HEADER_IN_TEXT,
for efficiency or to allow people to play games with the entry point.
In that case, you would #define N_HEADER_IN_TEXT(x) as 1 for sunos,
and as 0 for most other hosts (Sony News, Vax Ultrix, etc).

(The default is a heuristic that will break if people try changing
the entry point, perhaps with the ld -e flag.)

On a SPARC, the table is composed of 12 byte entries, each of

sethi %hi(0),%g1
jmp %g1
nop
These instructions are changed by ld.so into a jump directly into
ld.so itself. Each subsequent entry is
save %sp, -96, %sp
call <address of first entry in procedure linkage table>
<reloc_number | 0x01000000>
The reloc_number is the number of the reloc to use to resolve
this entry. The reloc will be a JMP_SLOT reloc against some
symbol that is not defined in this object file but should be
defined in a shared object (if it is not, ld.so will report a
runtime error and exit). The constant 0x010000000 turns the
reloc number into a sethi of %g0, which does nothing since %g0 is
hardwired to zero.
When one of these entries is executed, it winds up calling into
ld.so. ld.so looks at the reloc number, available via the return
address, to determine which entry this is. It then looks at the
reloc and patches up the entry in the table into a sethi and jmp
to the real address followed by a nop. This means that the reloc
lookup only has to happen once, and it also means that the
relocation only needs to be done if the function is actually
called. The relocation is expensive because ld.so must look up
the symbol by name.

Each entry in the hash table is eight bytes. The first four
bytes are a symbol index into the dynamic symbols. The second
four bytes are the index of the next hash table entry in the
bucket. The ld_buckets field gives the number of buckets, say B.
The first B entries in the hash table each start a bucket which
is chained through the second four bytes of each entry. A value
of zero ends the chain.
The hash function is simply
h = 0;
while (*string != '\0')
h = (h << 1) + *string++;
h &= 0x7fffffff;

the modulos of hash value and the number of buckets. Start at
that entry in the hash table. See if the symbol (from the first
four bytes of the hash table entry) has the name you are looking
for. If not, use the chain field (the second four bytes of the

* 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.

* FOR THE HEADER, AND READ ANY BYTE ORDER. PREFERENCE WOULD BE TO
* USE LITTLE-ENDIAN BYTE ORDER THROUGHOUT, REGARDLESS OF HOST. <==
*
* o The downloader ('comm960') takes care to generate a pseudo-header

/* There are various ways to handle system calls:
1) Have a simulator intercept the appropriate trap instruction and
directly perform the system call on behalf of the target program.
This is the typical way of handling system calls for embedded targets.
[Handling system calls for embedded targets isn't that much of an
oxymoron as running compiler testsuites make use of the capability.]
This method of system call handling is done when STATE_ENVIRONMENT
is ENVIRONMENT_USER.
2) Have a simulator emulate the hardware as much as possible.
If the program running on the real hardware communicates with some sort
of target manager, one would want to be able to run this program on the
simulator as well.
This method of system call handling is done when STATE_ENVIRONMENT
is ENVIRONMENT_OPERATING.

NOTE:
All the "I" forms refer to 29000 instruction formats. The linker is
expected to know how the numeric information is split and/or aligned
within the instruction word(s). R_BYTE works for instructions, too.
If the parameter to a CONSTH instruction is a relocatable type, two
relocation records are written. The first has an r_type of R_IHIHALF
(33 octal) and a normal r_vaddr and r_symndx. The second relocation
record has an r_type of R_IHCONST (34 octal), a normal r_vaddr (which
is redundant), and an r_symndx containing the 32-bit constant offset
to the relocation instead of the actual symbol table index. This
second record is always written, even if the constant offset is zero.
The constant fields of the instruction are set to zero.

The object file will contain the correct difference, and does not
require adjustment. However, when the linker is relaxing PC
relative calls, it is possible for $L3 to move farther away. This
reloc always appears in the .text section, and is always against
the .text section. However, the symbol index is not
RELOC_SECTION_TEXT. It is, instead, the distance between this
switch table entry and $LS12. Thus, the original value of $L12 is

*
* -----------------------------------------------------------------------
* A brief word about Third Eye naming/use conventions:
*
* All arrays and index's are 0 based.
* All "ifooMax" values are the highest legal value PLUS ONE. This makes
* them good for allocating arrays, etc. All checks are "ifoo < ifooMax".
*
* "isym" Index into the SYMbol table.
* "ipd" Index into the Procedure Descriptor array.
* "ifd" Index into the File Descriptor array.
* "iss" Index into String Space.
* "cb" Count of Bytes.
* "rgPd" array whose domain is "0..ipdMax-1" and RanGe is PDR.
* "rgFd" array whose domain is "0..ifdMax-1" and RanGe is FDR.
