Annotation of embedaddon/php/ext/pcre/pcrelib/testdata/testoutput2, revision 1.1.1.1
1.1 misho 1: /-- This set of tests is not Perl-compatible. It checks on special features
2: of PCRE's API, error diagnostics, and the compiled code of some patterns.
3: It also checks the non-Perl syntax the PCRE supports (Python, .NET,
4: Oniguruma). Finally, there are some tests where PCRE and Perl differ,
5: either because PCRE can't be compatible, or there is a possible Perl
6: bug. --/
7:
8: /-- Originally, the Perl >= 5.10 things were in here too, but now I have
9: separated many (most?) of them out into test 11. However, there may still
10: be some that were overlooked. --/
