DirectX Shader Compiler files in the Windows zip
================================================

Dawn's Direct3D 12 backend (webgpu_dawn.dll) loads both of these files at run
time. Both come with the Dawn package the port uses (encounter/dawn release
v20260807.225922) and are shipped unchanged. They come from different places
and are under different licences.

dxcompiler.dll  1.9.0.1 (DirectXShaderCompiler commit 13730886)
  Built from source as part of Dawn (Dawn's DEPS file pins this commit). It
  is the LLVM-based shader compiler, under the University of Illinois/NCSA
  Open Source License. LICENSE.TXT also has sections for the third-party code
  in the LLVM tree, and ThirdPartyNotices.txt lists the components Microsoft
  incorporated:
    dxcompiler-LICENSE.txt           (LICENSE.TXT at that commit)
    dxcompiler-ThirdPartyNotices.txt (ThirdPartyNotices.txt at that commit)
  Source: https://github.com/microsoft/DirectXShaderCompiler

dxil.dll  1.8.2502.11
  Microsoft's closed-source DXIL validator, a redistributable binary signed
  by Microsoft. It is not open source and none of the open-source licences
  in this folder cover it. Dawn's build copied it from the Windows SDK on the
  machine that built the Dawn package (the SDK's bin\<version>\x64 folder).
  The Windows SDK licence lets developers redistribute the files on the SDK's
  REDIST.TXT list ("Distributable Code", section 2.a), and that list names
  Redist\D3D\x64\dxil.dll
  (https://learn.microsoft.com/en-us/legal/windows-sdk/redist).

                                 from the DirectXShaderCompiler v1.8.2502
                                 GitHub release. These are Microsoft's terms
                                 for the same component as published in that
                                 release (whose dxil.dll is build
                                 1.8.2502.8). The file shipped here is the
                                 SDK's build, so the SDK terms above are the
                                 ones that apply to it; this file is kept for
                                 reference.
  dxil.dll is Microsoft software, and your use of it is subject to
  Microsoft's licence terms above.
