SimpleScalar is a popular cycle-level architectural simulator that
simulates a MIPS-like instruction set. It has thousands of users from
around the world. http://www.cs.wisc.edu/~mscalar/simplescalar.html
An older GNU toolchain (using binutils 2.5.2) is available for
SimpleScalar. I have moved the changes from 2.5.2 into the most
recent version of binutils. I would like to contribute these changes
to the binutils distribution so that others may use them and the tools
will continue to improve.
What do I need to do to make this happen?
It might be a bit tricky. The FSF requires copyright assignments from
all relevant authors. If you modified an existing patch, we will need
to get copyright assignments from the authors of the original patch.
Is that a possibility?
I've appended the copyright assignment form, with your name in it.
The way to assign copyright to the Foundation is to sign an assignment
contract. This is what legally makes the FSF the copyright holder so
that we can register the copyright on the new version.
I'm assuming that you wrote these changes yourself;
if other people wrote parts, we may need papers from them.
If you are employed to do programming (even at a university), or have
made an agreement with your employer or school saying it owns programs
you write, then you and we need a signed piece of paper from your
employer disclaiming rights to the program.
The disclaimer should be signed by a vice president or general manager
of the company. If you can't get at them, anyone else authorized to
license software produced there will do. Here is a sample wording:
Digital Stimulation Corporation hereby disclaims all copyright interest
in the changes and enhancements made by Hugh Heffner to the program
"seduce", also including any future revisions of these changes and
Digital Stimulation Corporation affirms that it has no other
intellectual property interest that would undermine this release, or
the use of the Program, and will do nothing to undermine it in the
<signature of Ty Coon>, 1 April 1987
Ty Coon, President of Vice, Digital Stimulation Corp.
(If your employer says they do have an intellectual property claim
that could conflict with the use of the program, then please put me in
touch with a suitable representative of the company, so that we can
negotiate what to do about it.)
IMPORTANT: When you talk to your employer, *no matter what
instructions they have given you*, don't fail to show them the sample
disclaimer above, or a disclaimer with the details filled in for your
specific case. Companies are usually willing to sign a disclaimer
without any fuss. If you make your request less specific, you may
open Pandora's box and cause a long and unnecessary delay.
Below is the assignment contract that we usually use. You would need
to print it out, sign it, and snail it to:
545 Tech Sq rm 425
Cambridge, MA 02139
Please try to print the whole first page below on a single piece of
paper. If it doesn't fit on one printed page, put it on two sides of
a single piece of paper.
Don't forget to put down the date when you sign! Spell out the month
name--don't use a number for the month. Dates using a number for the
month are ambiguous; 2/8/95 means one thing in the US and another in
Snail a copy of the employer's disclaimer as well.
Please send me email about what you decide to do. If you have any
questions, or would like something to be changed, ask firstname.lastname@example.org via email.
For good and valuable consideration, receipt of which I acknowledge, I,
Charles Lefurgy, hereby transfer to the Free Software Foundation, Inc. (the
"Foundation") my entire right, title, and interest (including all rights
under copyright) in my changes and enhancements to the GNU Binutils software
package, subject to the conditions below. These changes and enhancements
are herein called the "Work". The work hereby assigned shall also include
any future revisions of these changes and enhancements hereafter made by me.
Upon thirty days' prior written notice, the Foundation agrees to
grant me non-exclusive rights to use the Work (i.e. my changes and
enhancements, not the package which I enhanced) as I see fit; (and the
Foundation's rights shall otherwise continue unchanged).
For the purposes of this contract, a work "based on the Work" means
any work that in whole or in part incorporates or is derived from all or
part of the Work.
The Foundation promises that all distribution of the Work, or of any
work "based on the Work", that takes place under the control of the
Foundation or its assignees, shall be on terms that explicitly and
perpetually permit anyone possessing a copy of the work to which the terms
apply, and possessing accurate notice of these terms, to redistribute
copies of the work to anyone on the same terms. These terms shall not
restrict which members of the public copies may be distributed to. These
terms shall not require a member of the public to pay any royalty to the
Foundation or to anyone else for any permitted use of the work they apply
to, or to communicate with the Foundation or its agents in any way either
when redistribution is performed or on any other occasion.
The Foundation promises that any program "based on the Work" offered
to the public by the Foundation or its assignees shall be offered in the
form of machine-readable source code, in addition to any other forms of the
Foundation's choosing. However, the Foundation is free to choose at its
convenience the media of distribution for machine-readable source code.
The Foundation promises to give or send me, upon reasonable prior notice
and payment of a fee no more than twenty times the cost of the necessary
materials and postage, a copy of any or all of the works "based on the
Work" that it offers to the public or that it has offered within the
past six months, or that it distributed for the first time within the past
six months. For works that are programs, the machine-readable source code
shall be included. My request shall detail whether I wish to receive all
such works or specific works. My choice of works to request may affect the
cost and therefore the fee.
I hereby agree that if I have or acquire hereafter any patent or
interface copyright or other intellectual property interest dominating the
package enhanced by the Work (or use of that package), such dominating
interest will not be used to undermine the effect of this assignment, i.e.
the Foundation and the general public will be licensed to use, in that
package and its derivative works, without royalty or limitation, the
subject matter of the dominating interest. This license provision will be
binding on my heirs, assignees, or other successors to the dominating
interest, as well as on me.
I hereby represent and warrant that I am the sole copyright holder for the
Work and that I have the right and power to enter into this contract. I
hereby indemnify and hold harmless the Foundation, its officers, employees,
and agents against any and all claims, actions or damages (including
attorney's reasonable fees) asserted by or paid to any party on account of a
breach or alleged breach of the foregoing warranty. I make no other express
or implied warranty (including without limitation, in this disclaimer of
warranty, any warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE).
