# This tests that the ANYOF nodes generated by bracketed character classes are
# as expected.  The representation of these is not guaranteed, and this test
# may need to be updated if it changes.  But it is here to make sure that no
# unexpected changes occur.  These could come from faulty generation of the
# node, or faulty display of them (or both).  Because these causes come from
# very different parts of the regex compiler, it is unlikely that a commit
# would change both of them, so this test will adequately serve to test both.

# An array is used instead of a hash, so that the tests are carried out in the

# The next higher element is the expected compilation result.
#
# It is painful to port some of these to EBCDIC, as not only do the code point
# numbers change (for those < 256), but the order changes, as the compiled
# version is sorted by native code point order.  On EBCDIC, \r comes before
# \n, and 'k' before "K', for example.  So, the tests where there are
# differences are skipped on EBCDIC.  They are all at the beginning of the
# array, and a special marker entry is used to delmit the boundary between
# skipped and not skipped.
