# Overall strategy for what sorts of builds to include:
# We want a build for the newest and oldest supported version of each compiler.
# We want a build for each platform.
# We also want to ensure that each of the following tweaks are covered in at
# least one PR build:
# - TILES=1
# - SOUND=1
# - RELEASE=1
# - CMAKE=1
# - LOCALIZE=0
# - LTO=1
# - LIBBACKTRACE=1 (on Linux and Windows)
# - Tests with important mods enabled (Magiclysm)
# - A clang-tidy run
# - SANITIZE=address,undefined
# We try to minimize the number of builds subject to those constraints.
#
