# Known critical issues:
# - AVX512 related tests are incomplete.  Because default environment of
#   GitHub Actions doesn't guarantee to support AVX512.
#   As of May 2021, they're using Xeon E5-2673 (which doesn't support
#   AVX512) and Xeon Platinum 8171M (which supports AVX512).
#   See also https://github.com/actions/runner/issues/1069
#
#   In this CI script, it always run `make default` which compiles xxHash
#   with AVX512 intrinsics.  But if test runner doesn't support AVX512,
#   it doesn't run `make check` which tests runtime error/consistency.
#   It means that this test stochastically detects a failure in AVX512
#   code path.
#
# Known issues:
# - This test script ignores exit code of cppcheck which can see under
#   Job:Linux x64 misc tests > cppcheck in the GitHub Actions report.
#   Because xxHash project doesn't 100% follow their recommendation.
#   Also sometimes it reports false positives.
#
# - GitHub Actions doesn't support Visual Studio 2015 and 2013.
#   https://github.com/actions/virtual-environments/issues/387
#
# - Setup procedure for msys2 environment is painfully slow.  It takes
#   3..5 minutes.
#
# Notes:
# - You can investigate various information at the right pane of GitHub
#   Actions report page.
#
#   | Item                      | Section in the right pane             |

#
# - To fail earlier, order of tests in the same job are roughly sorted by
#   elapsed time.
#
# Todos:
# - [ ] Linux: Add native ARM runner.
# - [ ] Linux: Add native ARM64 runner.
# - [ ] Linux: Add native PPC64LE runner.
# - [ ] Linux: Add native S390X runner.
# - [ ] Windows: Add VS2013.
# - [ ] Windows: Add VS2015.
# - [ ] Windows: Add clang for msys2.
# - [ ] Windows: Add native or emulated ARM runner.
# - [ ] Windows: Add native or emulated ARM64 runner.
