source: tests/array-collections/dimexpr-match-detail.sh@ 8da3cc4d

# A test.py run (including what happens in the nightly build) runs the dimexpr-match test in a coarse, quick-check, fashion.
# This script helps you run the dimexpr-match test manually, in a more thorough fashion.
# test.py runs do not use this script.

# The thoroughness that this script affords is
#   - verifying that _each_ rejection case is rejected, among a huge number of rejection cases
#     - particularly, counting those that reject by way of CFACC calling GCC, which issues a warning; these rejections are not reached by getting CFACC to report all errors at once
#   - observing the behaviour of a compiler other than the CFACC version in whose folder the test occurs; for example, GCC
