Here, glslang proper means core GLSL parsing, HLSL parsing, and SPIR-V code
|
|
generation. Glslang proper requires use of a number of licenses, one that covers
|
|
preprocessing and others that covers non-preprocessing.
|
|
|
|
Bison was removed long ago. You can build glslang from the source grammar,
|
|
using tools of your choice, without using bison or any bison files.
|
|
|
|
Other parts, outside of glslang proper, include:
|
|
|
|
- gl_types.h, only needed for OpenGL-like reflection, and can be left out of
|
|
a parse and codegen project. See it for its license.
|
|
|
|
- update_glslang_sources.py, which is not part of the project proper and does
|
|
not need to be used.
|
|
|
|
- the SPIR-V "remapper", which is optional, but has the same license as
|
|
glslang proper
|
|
|
|
- Google tests and SPIR-V tools, and anything in the external subdirectory
|
|
are external and optional; see them for their respective licenses.

|
|
source, and configuration files.
|
|
|
|
"Object" form shall mean any form resulting from mechanical
|
|
transformation or translation of a Source form, including but
|
|
not limited to compiled object code, generated documentation,
|
|
and conversions to other media types.
|
|
|
|
"Work" shall mean the work of authorship, whether in Source or
|
|
Object form, made available under the License, as indicated by a
|
|
copyright notice that is included in or attached to the work
|
|
(an example is provided in the Appendix below).
|
|
|
|
"Derivative Works" shall mean any work, whether in Source or Object
|
|
form, that is based on (or derived from) the Work and for which the
|
|
editorial revisions, annotations, elaborations, or other modifications
|
|
represent, as a whole, an original work of authorship. For the purposes
|
|
of this License, Derivative Works shall not include works that remain
|
|
separable from, or merely link (or bind by name) to the interfaces of,
|
|
the Work and Derivative Works thereof.
|
|
|
|
"Contribution" shall mean any work of authorship, including
|
|
the original version of the Work and any modifications or additions
|
|
to that Work or Derivative Works thereof, that is intentionally
|
|
submitted to Licensor for inclusion in the Work by the copyright owner
|
|
or by an individual or Legal Entity authorized to submit on behalf of
|
|
the copyright owner. For the purposes of this definition, "submitted"
|
|
means any form of electronic, verbal, or written communication sent
|
|
to the Licensor or its representatives, including but not limited to
|
|
communication on electronic mailing lists, source code control systems,
|
|
and issue tracking systems that are managed by, or on behalf of, the
|
|
Licensor for the purpose of discussing and improving the Work, but
|
|
excluding communication that is conspicuously marked or otherwise
|
|
designated in writing by the copyright owner as "Not a Contribution."
|
|
|
|
"Contributor" shall mean Licensor and any individual or Legal Entity
|
|
on behalf of whom a Contribution has been received by Licensor and
|
|
subsequently incorporated within the Work.
|
|
|
|
2. Grant of Copyright License. Subject to the terms and conditions of
|
|
this License, each Contributor hereby grants to You a perpetual,
|
|
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
|
copyright license to reproduce, prepare Derivative Works of,
|
|
publicly display, publicly perform, sublicense, and distribute the
|
|
Work and such Derivative Works in Source or Object form.
|
|
|
|
3. Grant of Patent License. Subject to the terms and conditions of
|
|
this License, each Contributor hereby grants to You a perpetual,
|
|
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
|
(except as stated in this section) patent license to make, have made,
|
|
use, offer to sell, sell, import, and otherwise transfer the Work,
|
|
where such license applies only to those patent claims licensable
|
|
by such Contributor that are necessarily infringed by their
|
|
Contribution(s) alone or by combination of their Contribution(s)
|
|
with the Work to which such Contribution(s) was submitted. If You
|
|
institute patent litigation against any entity (including a
|
|
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
|
or a Contribution incorporated within the Work constitutes direct
|
|
or contributory patent infringement, then any patent licenses
|
|
granted to You under this License for that Work shall terminate
|
|
as of the date such litigation is filed.
|
|
|
|
4. Redistribution. You may reproduce and distribute copies of the
|
|
Work or Derivative Works thereof in any medium, with or without
|
|
modifications, and in Source or Object form, provided that You
|
|
meet the following conditions:
|
|
|
|
(a) You must give any other recipients of the Work or
|
|
Derivative Works a copy of this License; and
|
|
|
|
(b) You must cause any modified files to carry prominent notices
|
|
stating that You changed the files; and
|
|
|
|
(c) You must retain, in the Source form of any Derivative Works
|
|
that You distribute, all copyright, patent, trademark, and
|
|
attribution notices from the Source form of the Work,
|
|
excluding those notices that do not pertain to any part of
|
|
the Derivative Works; and
|
|
|
|
(d) If the Work includes a "NOTICE" text file as part of its
|
|
distribution, then any Derivative Works that You distribute must
|
|
include a readable copy of the attribution notices contained
|
|
within such NOTICE file, excluding those notices that do not
|
|
pertain to any part of the Derivative Works, in at least one
|
|
of the following places: within a NOTICE text file distributed
|
|
as part of the Derivative Works; within the Source form or
|
|
documentation, if provided along with the Derivative Works; or,
|
|
within a display generated by the Derivative Works, if and
|
|
wherever such third-party notices normally appear. The contents
|
|
of the NOTICE file are for informational purposes only and
|
|
do not modify the License. You may add Your own attribution
|
|
notices within Derivative Works that You distribute, alongside
|
|
or as an addendum to the NOTICE text from the Work, provided
|
|
that such additional attribution notices cannot be construed
|
|
as modifying the License.
|
|
|
|
You may add Your own copyright statement to Your modifications and
|
|
may provide additional or different license terms and conditions
|
|
for use, reproduction, or distribution of Your modifications, or
|
|
for any such Derivative Works as a whole, provided Your use,
|
|
reproduction, and distribution of the Work otherwise complies with
|
|
the conditions stated in this License.
|
|
|
|
5. Submission of Contributions. Unless You explicitly state otherwise,
|
|
any Contribution intentionally submitted for inclusion in the Work
|
|
by You to the Licensor shall be under the terms and conditions of
|
|
this License, without any additional terms or conditions.
|
|
Notwithstanding the above, nothing herein shall supersede or modify
|
|
the terms of any separate license agreement you may have executed
|
|
with Licensor regarding such Contributions.
|
|
|
|
6. Trademarks. This License does not grant permission to use the trade
|
|
names, trademarks, service marks, or product names of the Licensor,
|
|
except as required for reasonable and customary use in describing the
|
|
origin of the Work and reproducing the content of the NOTICE file.
|
|
|
|
7. Disclaimer of Warranty. Unless required by applicable law or
|
|
agreed to in writing, Licensor provides the Work (and each
|
|
Contributor provides its Contributions) on an "AS IS" BASIS,
|
|
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
|
implied, including, without limitation, any warranties or conditions
|
|
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
|
PARTICULAR PURPOSE. You are solely responsible for determining the
|
|
appropriateness of using or redistributing the Work and assume any
|
|
risks associated with Your exercise of permissions under this License.
|
|
|
|
8. Limitation of Liability. In no event and under no legal theory,
|
|
whether in tort (including negligence), contract, or otherwise,
|
|
unless required by applicable law (such as deliberate and grossly
|
|
negligent acts) or agreed to in writing, shall any Contributor be
|
|
liable to You for damages, including any direct, indirect, special,
|
|
incidental, or consequential damages of any character arising as a
|
|
result of this License or out of the use or inability to use the
|
|
Work (including but not limited to damages for loss of goodwill,
|
|
work stoppage, computer failure or malfunction, or any and all
|
|
other commercial damages or losses), even if such Contributor
|
|
has been advised of the possibility of such damages.
|
|
|
|
9. Accepting Warranty or Additional Liability. While redistributing
|
|
the Work or Derivative Works thereof, You may choose to offer,
|
|
and charge a fee for, acceptance of support, warranty, indemnity,
|
|
or other liability obligations and/or rights consistent with this
|
|
License. However, in accepting such obligations, You may act only
|
|
on Your own behalf and on Your sole responsibility, not on behalf
|
|
of any other Contributor, and only if You agree to indemnify,
|
|
defend, and hold each Contributor harmless for any liability
|
|
incurred by, or claims asserted against, such Contributor by reason
|
|
of your accepting any such warranty or additional liability.
|
|
|
|
END OF TERMS AND CONDITIONS
|
|
|
|
APPENDIX: How to apply the Apache License to your work.
|
|
|
|
To apply the Apache License to your work, attach the following
|
|
boilerplate notice, with the fields enclosed by brackets "[]"
|
|
replaced with your own identifying information. (Don't include
|
|
the brackets!) The text should be enclosed in the appropriate
|
|
comment syntax for the file format. We also recommend that a
|
|
file or class name and description of purpose be included on the
|
|
same "printed page" as the copyright notice for easier
|
|
identification within third-party archives.
