# 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 the main set of tests
|
|
# -nomainvalgrind skip the non-JIT valgrind tests
|
|
# -notmp skip the test in a temporary directory
|
|
# -novalgrind skip the valgrind tests
|
|
|
|
# The -v option causes a call to 'pcre2test -C' to happen for each
|
|
# configuration.
