# NOTE(quickstep-team): In Travis-CI, jobs timeout if they take more than 50
# mins or if there is no log output for more than 10 mins. Hence, we use -O0 to
# speed up compilation in release build. Also, jobs can only use upto 20GB of
# disk space. Hence, we minimize the amount of debug symbol using -g0 (DEBUG
# builds were taking > 20GB of space with clang).
# Also, to reduce the total CI time, we explicitly run the most time-consuming
# build first, using gcc in debug build with joinwithbinaryexpressions.
