RunTest

#! /bin/sh

###############################################################################
# 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, these tests are always
# run in numerical order.
#
# If no specific tests are selected (which is the case when this script is run
# via 'make check') the default is to run all the numbered tests.
#
# There may also be named (as well as numbered) tests for special purposes. At
# present there is just one, called "heap". This test's output contains the
# sizes of heap frames and frame vectors, which depend on the environment. It
# is therefore not run unless explicitly requested.
#
# Inappropriate tests are automatically skipped (with a comment to say so). For
# example, if JIT support is not compiled, test 16 is skipped, whereas if JIT
# support is compiled, test 15 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"
#
# For backwards compatibility, -nojit, -valgrind, -valgrind-log, and -sim may
# be given without the leading "-" character.
#
# When PCRE2 is compiled by clang with -fsanitize arguments, some tests need
# very much more stack than normal. In environments where the stack can be
# set at runtime, -bigstack sets a gigantic stack.
#
# Special cases where only one argument is allowed:
#   - If the script is invoked as "RunTest list", a list of available tests is
#     output, but none of them are run.
