# This is a script for the use of PCRE2 maintainers. It configures and rebuilds
# PCRE2 with a variety of configuration options, and in each case runs the
# tests to ensure that all goes well. Every possible combination would take far
# too long, so we use a representative sample. This script should be run in the
# PCRE2 source directory.
# While debugging, it is sometimes useful to be able to cut out some of the
# tests, in order to run those that are giving errors. The following options
# do this:
#
# -noasan skip the test that uses -fsanitize=address
# -nousan skip the test that uses -fsanitize=undefined
# -nodebug skip the test that uses --enable-debug
# -nojit skip all JIT tests
# -nojitmain skip non-valgrind JIT tests
# -nojitvalgrind skip JIT tests with valgrind
# -nomain skip all the main (non-JIT) set of tests
# -nomainvalgrind skip the main (non-JIT) valgrind tests
# -notmp skip the test in a temporary directory
# -novalgrind skip all the valgrind tests
# Alternatively, if any of those names are given with '+' instead of '-no',
# only those groups named with '+' are run (e.g. +jit). If -dummy is given,
# no tests are actually run - this provides a means of testing the selectors.
# The -v option causes a call to 'pcre2test -C' to happen for each
# configuration.
