| | | | | | | | | | | | | | This reverts commit b419f96c626d1f9cbbba42698e947e32a0af9c4f. This breaks the GCC build with -fcf-protection (default on Ubuntu at least).

Because the warning is based on an intra-procedural data flow analysis, the compiler does not see that cmp1b and cmp2b are not used when they are not initialized. Here is the code of that function, cmp2 is only used when ctype is compare_match2 or compare_match1i, and not when ctype is compare_match1: static inline vect_t fast_forward_char_pair_compare(compare_type ctype, vect_t dst, vect_t cmp1, vect_t cmp2) { if (ctype == compare_match2) { vect_t tmp = dst; dst = VCEQQ(dst, cmp1); tmp = VCEQQ(tmp, cmp2); dst = VORRQ(dst, tmp); return dst; } if (ctype == compare_match1i) dst = VORRQ(dst, cmp2); dst = VCEQQ(dst, cmp1); return dst; } The patch inlines by hand the case of compare_match1 such that the code avoids referring to cmp1b and cmp2b. Tested on aarch64-linux with `make check`.

| * Fixed bug #78272Nikita Popov2019-09-181-1/+14
| | | | | | | | | | | | | | | | Use MAP_JIT only when running under hardened runtime, because MAP_JIT is incompatible with fork(). The check is based on https://github.com/mono/mono/commit/f879e35e3ed7496d819bd766deb8be6992d068ed.
| * Backport MAP_JIT fixes from PCRE2 10.33Nikita Popov2019-09-181-3/+43
| | | | | | | | | | | | | | | | This is intended to fix the primary issue from bug #77260. Prior to macOS 10.14 multiple MAP_JIT segments were not permitted, leading to mmap failures and corresponding "no more memory" errors on macOS 10.13.

* | Disable PACKAGE_* preprocessor symbolsPeter Kokot2019-04-131-5/+0
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Autoconf defines PACKAGE_* symbols: - PACKAGE_NAME - PACKAGE_VERSION - PACKAGE_TARNAME - PACKAGE_STRING - PACKAGE_BUGREPORT - PACKAGE_URL and appends them to the generated config.h.in files. With AC_INIT change via afd52f9d9986d92dd0c63832a07ab1a16bf11d53 where package version, URL, bug report location and similar meta data are defined, these preprocessor macros are then non empty strings in the generated configuration header file. When using phpize, PHP shares the config files in extensions, warnings of redefined macros appear, such as: - `warning: 'PACKAGE_NAME' macro redefined` This patch now disables these non utilized symbols in the generated config header files. Better practice would be to include only API specific headers where needed but this would require even more refactorings. Some extensions such as pcre, pgsql, and pdo_pgsql solve this issue by undefining some of these symbols before including the library configuration headers in the code also. Because these symbols can be defined by any library which uses Autotools. Additionally, the unused PACKAGE_* symbols were cleaned for the bundled libmbfl library and with this patch not needed undef code removed.
