Deploy binaries from travis.ci

This workflow allows us to test attached binaries before publishing the release.

• Go to https://travis-ci.org/KhronosGroup/SPIRV-LLVM-Translator
• Choose "More options" -> "Trigger build"
• Pick a branch or commit for the release
  • Commit message is irrelevant.
• Insert the following config
  • Note: The branch in deploy.on must match with the one picked for the build # (previous item)
  • Note: TRAVIS_TAG will be used for the release on github.
  • Note: This is a draft release. i.e. it is available for KhronosGroup members only.

before_deploy:
  - echo ${TRAVIS_COMMIT} > ../install/version.txt;
  - export TRAVIS_TAG=v8.0.1-2
  - export TARBALL=SPIRV-LLVM-Translator-${TRAVIS_TAG}-${TRAVIS_OS_NAME}-${BUILD_TYPE}.zip;
  - cd ../install && find . -print | zip -@ ${TARBALL};

deploy:
  provider: releases
  api_key: ${repo_token}
  on:
    branch: llvm_release_80
    condition: ${BUILD_EXTERNAL} == 1 && ${SHARED_LIBS} == ON && ${repo_token}
  file: ${TARBALL}
  skip_cleanup: true
  overwrite: false
  draft: true

• Click "Trigger custom build" and wait while the first two builds complete.
• Go to https://github.com/KhronosGroup/SPIRV-LLVM-Translator/releases. A "Draft" release should be created there by travis.
  • Make sure built artifacts are attached.
• Edit the release as needed.
  • Set the branch
  • Provide meaningful title for the release
  • Provide a description / release notes.
• Review the release with the community
• Once we are happy with the draft, publish it.
