# NOTE #1: Our GitLab CI runs jobs inside Alpine Linux container by default.
#
# NOTE #2: Keep in mind that each job (e.g. test-gcc) is executed in a separate
# isolated environment (it may be even on different machine). There are no
# files implicitly passed between jobs or stages, only artifacts and maybe
# cache (depends on configuration).
