# Copyright (c) 2017, ARM Limited, All Rights Reserved
|
|
#
|
|
# Purpose
|
|
#
|
|
# To test the code dependencies on individual hashes in each test suite. This
|
|
# is a verification step to ensure we don't ship test suites that do not work
|
|
# for some build options.
|
|
#
|
|
# The process is:
|
|
# for each possible hash
|
|
# build the library and test suites with the hash disabled
|
|
# execute the test suites
|
|
#
|
|
# And any test suite with the wrong dependencies will fail.
|
|
#
|
|
# Usage: tests/scripts/depends-hashes.pl
|
|
#
|
|
# This script should be executed from the root of the project directory.
|
|
#
|
|
# For best effect, run either with cmake disabled, or cmake enabled in a mode
|
|
# that includes -Werror.
