The builtin has been available in gcc since 4.7.0 and in clang since 2.6. This fixes stpncpy fortification with clang since it does a better job of plugging in __stpncpy_chk in the right place than the header hackery. This has been tested by building and running all tests with gcc 10.2.1 and also with clang tip as of a few days ago (just the tests in debug/ since running all tests don't work with clang at the moment) to make sure that both compilers pass the stpncpy tests. |
