# This script exists to exercise breaking each of the FIPS tests on an Android
# device. Since, on Android, BoringCrypto exists in both 32- and 64-bit
# versions, the first argument must be either "32" or "64" to select which is
# being tested. The Android source tree must have been setup (with "lunch") for
# a matching build configuration before using this script to build the
# binaries. (Although it'll fail non-silently if there's a mismatch.)
#
# Since each test needs the FIPS module to be compiled differently, and that
# can take a long time, this script is run twice: once with "build" as the
# second argument to run the builds, and then with "run" as the second argument
# to run each test.
#
# Run it with /bin/bash, not /bin/sh, otherwise "read" may fail.
#
# In order to reconfigure the build for each test, it needs to set a define. It
# does so by rewriting a template in external/boringssl/Android.bp and you must
# add the template value before doing the builds. To do so, insert
# -DBORINGSSL_FIPS_BREAK_XXX=1 in the cflags list for the module, probably by
# putting it in the "boringssl_flags" stanza.
