# During the transition of CI associated with the repo split,
# we want all.sh from the mbedtls repo to transparently run both
# mbedtls and tf-psa-crypto components.
# This is what this wrapper is about.
# Once the transition is over, this wrapper can be removed,
# and mbedtls-all.sh renamed again to all.sh.
#
# This wrapper is mostly for the CI's benefit. Developers probably want to
# directly invoke one or two of the following commands:
# - tests/scripts/mbedtls-all.sh ...
# - (cd tf-psa-crypto && tests/scripts/all.sh ...)

# This script must be invoked from the project's root.

# all.sh complains when a component is requested explicitly but is not
# available. However, here we actually run two instances of all.sh, so when
# requesting one component epxlicitly, at least one instance is not going to
# know about it. So, when invoking each side, remove the other side's
# components from its command line. This is safe because we know from above
# that no component is on both sides.
