This is the gdbstubs project.
This software is provided WITHOUT WARRANTY of any kind.
You may reproduce, modify, display, perform, sublicense and/or
distribute the contents of this project, with or without
modifications, or as part of a larger work, under the following
conditions:
Preamble
--------
Gdbstubs itself is intended to be Free Software (no, not Open Source
Software). The terms herein are intended to follow the spirit of the
GNU General Public License, but in an embedded-friendly setting.
Gdbstubs is intended for use in Free, Open, and proprietary embedded
systems. The goal, however, is that each time gdbstubs is ported to a
new processor architecture or evaluation board, some code comes back to
the mainline distribution so that others may benefit.
Share and share alike.
There are very few "proprietary parts" in gdbstubs, as the
architecture lends itself to openness. The only parts of gdbstubs
that I could consider to be even potentially proprietary are your
implementations of getc(), putc() and startup(). As you will see in
the Terms section, such parts do not fall under the terms of this
license, but with a caveat.
An implementation of gdbstubs for a processor architecture that the
GNU compiler already supports would not be considered proprietary,
because all you are doing is modifying the internals of gdbstubs
itself (the implementations of gdb_step(), etc.). All such code
should come back into the mainline gdbstubs for redistribution.
Share and share alike.
Share and share alike.
Definitions
-----------
"Modification" -- an addition to or deletion from the substance or
structure of either the original gdbstubs code, or a derivative
thereof.
"License" -- this document.
Terms
-----
1. The gdbstubs Modifications you create or to which you contribute
must be governed by the terms of this License, without limitation.
2. You must include an unmodified copy of this License with every copy
of the gdbstubs source code you distribute. You may rename this file
to COPYING.gdbstubs if necessary. You must inform your users of the
rights they have under this License.
3. Any gdbstubs Modification which you create or to which you contribute
must be made available in source code form under the terms of this
License.
4. Implemenations of gdb_getc(), gdb_putc(), and gdb_startup(),
although they frequently appear in the gdbstubs source code, are not
considered part of gdbstubs, and may remain proprietary if you like,
subject to the stipulations in Item 5 of the Terms.
5. If you produce a Modification of gdbstubs for a processor or
architecture that was previously unsupported by gdbstubs, you must,
to the best of your ability, also provide a compatible and suitably
generic implementation of gdb_getc(), gdb_putc(), and gdb_startup()
for reference.
