# These are:
#
# (1) Tests of the match-limiting features. The results are different for
# interpretive or JIT matching, so this test should not be run with JIT. The
# same tests are run using JIT in test 17.

# (2) Other tests that must not be run with JIT.

# These tests are first so that they don't inherit a large enough heap frame
# vector from a previous test.
