14      and distribution as defined by Sections 1 through 9 of this document.
15
16      "Licensor" shall mean the copyright owner or entity authorized by
17      the copyright owner that is granting the License.
18
19      "Legal Entity" shall mean the union of the acting entity and all
20      other entities that control, are controlled by, or are under common
21      control with that entity. For the purposes of this definition,

23      direction or management of such entity, whether by contract or
24      otherwise, or (ii) ownership of fifty percent (50%) or more of the
25      outstanding shares, or (iii) beneficial ownership of such entity.
26
27      "You" (or "Your") shall mean an individual or Legal Entity
28      exercising permissions granted by this License.
29
30      "Source" form shall mean the preferred form for making modifications,
31      including but not limited to software source code, documentation
32      source, and configuration files.
33
34      "Object" form shall mean any form resulting from mechanical
35      transformation or translation of a Source form, including but
36      not limited to compiled object code, generated documentation,
37      and conversions to other media types.
38
39      "Work" shall mean the work of authorship, whether in Source or
40      Object form, made available under the License, as indicated by a
41      copyright notice that is included in or attached to the work
42      (an example is provided in the Appendix below).
43
44      "Derivative Works" shall mean any work, whether in Source or Object
45      form, that is based on (or derived from) the Work and for which the
46      editorial revisions, annotations, elaborations, or other modifications
47      represent, as a whole, an original work of authorship. For the purposes
48      of this License, Derivative Works shall not include works that remain
49      separable from, or merely link (or bind by name) to the interfaces of,
50      the Work and Derivative Works thereof.
51
52      "Contribution" shall mean any work of authorship, including
53      the original version of the Work and any modifications or additions
54      to that Work or Derivative Works thereof, that is intentionally
55      submitted to Licensor for inclusion in the Work by the copyright owner
56      or by an individual or Legal Entity authorized to submit on behalf of
57      the copyright owner. For the purposes of this definition, "submitted"
58      means any form of electronic, verbal, or written communication sent
59      to the Licensor or its representatives, including but not limited to
60      communication on electronic mailing lists, source code control systems,
61      and issue tracking systems that are managed by, or on behalf of, the
62      Licensor for the purpose of discussing and improving the Work, but
63      excluding communication that is conspicuously marked or otherwise
64      designated in writing by the copyright owner as "Not a Contribution."
65
66      "Contributor" shall mean Licensor and any individual or Legal Entity
67      on behalf of whom a Contribution has been received by Licensor and
68      subsequently incorporated within the Work.
69
70    2. Grant of Copyright License. Subject to the terms and conditions of
71      this License, each Contributor hereby grants to You a perpetual,
72      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
73      copyright license to reproduce, prepare Derivative Works of,
74      publicly display, publicly perform, sublicense, and distribute the
75      Work and such Derivative Works in Source or Object form.
76
77    3. Grant of Patent License. Subject to the terms and conditions of
78      this License, each Contributor hereby grants to You a perpetual,
79      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
80      (except as stated in this section) patent license to make, have made,
81      use, offer to sell, sell, import, and otherwise transfer the Work,
82      where such license applies only to those patent claims licensable
83      by such Contributor that are necessarily infringed by their
84      Contribution(s) alone or by combination of their Contribution(s)
85      with the Work to which such Contribution(s) was submitted. If You
86      institute patent litigation against any entity (including a
87      cross-claim or counterclaim in a lawsuit) alleging that the Work
88      or a Contribution incorporated within the Work constitutes direct
89      or contributory patent infringement, then any patent licenses
90      granted to You under this License for that Work shall terminate
91      as of the date such litigation is filed.
92
93    4. Redistribution. You may reproduce and distribute copies of the
94      Work or Derivative Works thereof in any medium, with or without
95      modifications, and in Source or Object form, provided that You
96      meet the following conditions:
97
98      (a) You must give any other recipients of the Work or
99          Derivative Works a copy of this License; and
100
101      (b) You must cause any modified files to carry prominent notices
102          stating that You changed the files; and
103
104      (c) You must retain, in the Source form of any Derivative Works
105          that You distribute, all copyright, patent, trademark, and
106          attribution notices from the Source form of the Work,
107          excluding those notices that do not pertain to any part of
108          the Derivative Works; and
109
110      (d) If the Work includes a "NOTICE" text file as part of its
111          distribution, then any Derivative Works that You distribute must
112          include a readable copy of the attribution notices contained
113          within such NOTICE file, excluding those notices that do not
114          pertain to any part of the Derivative Works, in at least one
115          of the following places: within a NOTICE text file distributed
116          as part of the Derivative Works; within the Source form or
117          documentation, if provided along with the Derivative Works; or,
118          within a display generated by the Derivative Works, if and
119          wherever such third-party notices normally appear. The contents
120          of the NOTICE file are for informational purposes only and
121          do not modify the License. You may add Your own attribution
122          notices within Derivative Works that You distribute, alongside
123          or as an addendum to the NOTICE text from the Work, provided
124          that such additional attribution notices cannot be construed
125          as modifying the License.
126
127      You may add Your own copyright statement to Your modifications and
128      may provide additional or different license terms and conditions
129      for use, reproduction, or distribution of Your modifications, or
130      for any such Derivative Works as a whole, provided Your use,
131      reproduction, and distribution of the Work otherwise complies with
132      the conditions stated in this License.
133
134    5. Submission of Contributions. Unless You explicitly state otherwise,
135      any Contribution intentionally submitted for inclusion in the Work
136      by You to the Licensor shall be under the terms and conditions of
137      this License, without any additional terms or conditions.
138      Notwithstanding the above, nothing herein shall supersede or modify
139      the terms of any separate license agreement you may have executed
140      with Licensor regarding such Contributions.
141
142    6. Trademarks. This License does not grant permission to use the trade
143      names, trademarks, service marks, or product names of the Licensor,
144      except as required for reasonable and customary use in describing the
145      origin of the Work and reproducing the content of the NOTICE file.
146
147    7. Disclaimer of Warranty. Unless required by applicable law or
148      agreed to in writing, Licensor provides the Work (and each
149      Contributor provides its Contributions) on an "AS IS" BASIS,
150      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
151      implied, including, without limitation, any warranties or conditions
152      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
153      PARTICULAR PURPOSE. You are solely responsible for determining the
154      appropriateness of using or redistributing the Work and assume any
155      risks associated with Your exercise of permissions under this License.
156
157    8. Limitation of Liability. In no event and under no legal theory,
158      whether in tort (including negligence), contract, or otherwise,
159      unless required by applicable law (such as deliberate and grossly
160      negligent acts) or agreed to in writing, shall any Contributor be
161      liable to You for damages, including any direct, indirect, special,
162      incidental, or consequential damages of any character arising as a
163      result of this License or out of the use or inability to use the
164      Work (including but not limited to damages for loss of goodwill,
165      work stoppage, computer failure or malfunction, or any and all
166      other commercial damages or losses), even if such Contributor
167      has been advised of the possibility of such damages.
168
169    9. Accepting Warranty or Additional Liability. While redistributing
170      the Work or Derivative Works thereof, You may choose to offer,
171      and charge a fee for, acceptance of support, warranty, indemnity,
172      or other liability obligations and/or rights consistent with this
173      License. However, in accepting such obligations, You may act only
174      on Your own behalf and on Your sole responsibility, not on behalf
175      of any other Contributor, and only if You agree to indemnify,
176      defend, and hold each Contributor harmless for any liability
177      incurred by, or claims asserted against, such Contributor by reason
178      of your accepting any such warranty or additional liability.

182    APPENDIX: How to apply the Apache License to your work.
183
184      To apply the Apache License to your work, attach the following
185      boilerplate notice, with the fields enclosed by brackets "[]"
186      replaced with your own identifying information. (Don't include
187      the brackets!)  The text should be enclosed in the appropriate
188      comment syntax for the file format. We also recommend that a
189      file or class name and description of purpose be included on the
190      same "printed page" as the copyright notice for easier
191      identification within third-party archives.

208---- LLVM Exceptions to the Apache 2.0 License ----
209
210As an exception, if, as a result of your compiling your source code, portions
211of this Software are embedded into an Object form of such source code, you
212may redistribute such embedded portions in such Object form without complying
213with the conditions of Sections 4(a), 4(b) and 4(d) of the License.
214
215In addition, if you combine or link compiled forms of this Software with
216software that is licensed under the GPLv2 ("Combined Software") and if a
217court of competent jurisdiction determines that the patent provision (Section
2183), the indemnity provision (Section 9) or other Section of the License
219conflicts with the conditions of the GPLv2, you may retroactively and
220prospectively choose to deem waived or otherwise exclude such Section(s) of
221the License, but only in their entirety and only with respect to the Combined
222Software.
