Wasmer Attributions
Wasmer is a community effort and makes use of code from various other projects. Listed below are notable sections of code that are licensed from other projects and the relevant license of those projects.
These are the projects that were used as inspiration and/or that we are using code from:
- Nebulet: as the base for creating a great Rust WebAssembly runtime
- WAVM: for their great integration and testing framework
- greenwasm: for their spectests framework
- wasmtime:
For their mmap implementation, the wast test implementation and the implementation of the
__jit_debug_register_code
function in Rust, the structure of using Cranelift with the GDB JIT interface including implementation details regarding the structure of generating debug information for each function with Cranelift (for example, the sorting of the extended basic blocks before processing the instructions), and the API for transforming DWARF see wasm-debug's attribution file for more information - stackoverflow: to create an efficient HashMap with pair keys
- Emscripten: for emtests test sources to ensure compatibility
- The WebAssembly spec: for implementation details of WebAssembly and spectests
Please let us know if you believe there is an error or omission in this list and we will do our best to correct it.

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

(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and

distribution, then any Derivative Works that You distribute must

of the following places: within a NOTICE text file distributed

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.

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.

Emscripten
Emscripten is available under 2 licenses, the MIT license and the
University of Illinois/NCSA Open Source License.
Both are permissive open source licenses, with little if any
practical difference between them.
The reason for offering both is that (1) the MIT license is
well-known, while (2) the University of Illinois/NCSA Open Source
License allows Emscripten's code to be integrated upstream into
LLVM, which uses that license, should the opportunity arise.
The full text of both licenses follows.
