.travis.yml

language: c

#
# Try building on these 4 architectures; all are 64-bit, and all but
# "s390x", a/k/a z/Architecture, are little-endian. The crypto library
# on little-endian PowerPC/Power ISA does some things that require more
# careful adherence to the documentation, so it's useful for testing
# that.
#

os:
  - linux

dist: focal

#
# Linux runs on all of the architectures listed above; macOS runs on
# 64-bit x86 and 64-bit ARM, but Travis doesn't currently have a 64-bit
# ARM macOS build environment.  Suppress the macOS builds that don't work.
#
# In addition, with newer versions of macOS, Apple ships a "gcc" that's
# just another front end to Clang, presumably for backwards
# compatibility with build scripts etc. that expect the compiler to be
# "gcc", so don't bother doing "gcc" builds on macOS.
#
# Furthermore, the Coverity-branch builds seem to time out on the
# non-x86 platforms, so suppress them as well.  (Are they supported
# at all?)
#
# XXX - what is the fast_finish clause there for?  According to
#
#    https://docs.travis-ci.com/user/build-matrix/#fast-finishing
#
# "If some rows in the build matrix are allowed to fail, the build
# won't be marked as finished until they have completed.
#
# To mark the build as finished as soon as possible, add fast_finish:
# true to the jobs section of your .travis.yml like this:
#
# jobs:
#   fast_finish: true
#
# Now, the build result will be determined as soon as all the required
# jobs finish, based on these results, while the rest of the
# allow_failures jobs continue to run."
#
# but we *have* no allow_failures jobs.
