Regex: Add PCRE 8.32 in tools directory.
2014-07-04 22:28:24 +00:00
/-- This set of tests is not Perl-compatible. It checks on special features
of PCRE's API, error diagnostics, and the compiled code of some patterns.
It also checks the non-Perl syntax the PCRE supports (Python, .NET,
Oniguruma). Finally, there are some tests where PCRE and Perl differ,
either because PCRE can't be compatible, or there is a possible Perl
bug.
NOTE: This is a non-UTF set of tests. When UTF support is needed, use
test 5, and if Unicode Property Support is needed, use test 7. --/
