Message : Infrastructure for uploading flex/bison binaries The binaries are retrieved from MSys2 on windows and built from source on Linux. Updates to these binaries should be infrequent enough to not warrant a completely automated system. Bug: angleproject:3419 Change-Id: I282f9ca14059d1fe0d88f2ffd31d02df0ea6b88f Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1940571 Reviewed-by: Jonah Ryan-Davis <jonahr@google.com> Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org>

# update_glslang_binary.py:
#   Helper script to update the version of glslang in cloud storage.
#   This glslang is used to precompile Vulkan shaders. This script builds
#   glslang and uploads it to the bucket for Windows or Linux. It
#   currently only works on Windows and Linux. It also will update the
#   hashes stored in the tree. For more info see README.md in this folder.
