Copy regex-related files back from Gnulib, to fix a problem with static checking of regex calls noted by Martin Sebor. This merges the following changes: * New macro __attribute_nonnull__ in misc/sys/cdefs.h, for use later when copying other files back from Gnulib. * Use __GNULIB_CDEFS instead of __GLIBC__ when deciding whether to include bits/wordsize.h etc. * Avoid duplicate entries in epsilon closure table. * New regex.h macro _REGEX_NELTS to let regexec say that its pmatch arg should contain nmatch elts. Use that for regexec, instead of __attr_access (which is incorrect). * New regex.h macro _Attr_access_ which is like __attr_access except portable to non-glibc platforms. * Add some DEBUG_ASSERTs to pacify gcc -fanalyzer and to catch recently-fixed performance bugs if they recur. * Add Gnulib-specific stuff to port the dynarray- and lock-using parts of regex code to non-glibc platforms. * Fix glibc bug 11053. * Avoid some undefined behavior when popping an empty fail stack. |
