###############################################################################
# Run the PCRE2 tests using the pcre2test program. The appropriate tests are
# selected, depending on which build-time options were used.
#
# When JIT support is available, all appropriate tests are run with and without
# JIT, unless "nojit" is given on the command line. There are also two tests
# for JIT-specific features, one to be run when JIT support is available
# (unless "nojit" is specified), and one when it is not.
#
# Whichever of the 8-, 16- and 32-bit libraries exist are tested. It is also
# possible to select which to test by giving "-8", "-16" or "-32" on the
# command line.
#
# As well as "nojit", "-8", "-16", and "-32", arguments for this script are
# individual test numbers, ranges of tests such as 3-6 or 3- (meaning 3 to the
# end), or a number preceded by ~ to exclude a test. For example, "3-15 ~10"
# runs tests 3 to 15, excluding test 10, and just "~10" runs all the tests
# except test 10. Whatever order the arguments are in, the tests are always run
# in numerical order.
#
# The special argument "3S" runs test 3, stopping if it fails. Test 3 is the
# locale test, and failure usually means there's an issue with the locale
# rather than a bug in PCRE2, so normally subsequent tests are run. "3S" is
# useful when you want to debug or update the test.
#
# Inappropriate tests are automatically skipped (with a comment to say so): for
# example, if JIT support is not compiled, test 12 is skipped, whereas if JIT
# support is compiled, test 13 is skipped.
#
# Other arguments can be one of the words "valgrind", "valgrind-log", or "sim"
# followed by an argument to run cross-compiled executables under a simulator,
# for example:
#
# RunTest 3 sim "qemu-arm -s 8388608"
#
# There are two special cases where only one argument is allowed:
#
# If the first and only argument is "ebcdic", the script runs the special
# EBCDIC test that can be useful for checking certain EBCDIC features, even
# when run in an ASCII environment.
#
# If the script is obeyed as "RunTest list", a list of available tests is
# output, but none of them are run.

# of them are modified (e.g. with -8 or -16) when used in the actual tests.

Subsequent patterns automatically have the PCRE2_NEVER_UTF and PCRE2_NEVER_UCP
options set, which locks out the use of UTF and Unicode property features. This
is a trigger guard that is used in test files to ensure that UTF/Unicode tests
are not accidentally added to files that are used when UTF support is not
included in the library. This effect can also be obtained by the use of
\fB#pattern\fP; the difference is that \fB#forbid_utf\fP cannot be unset, and
the automatic options are not displayed in pattern information, to avoid
cluttering up test output.
