2000-10-30 Stefan Monnier * regex.c (re_iswctype, re_wctype_to_bit): Fix braino. (regex_compile): Catch bogus \(\1\). 2000-10-27 Stefan Monnier * regex.c (POP_FAILURE_REG_OR_COUNT, re_match_2_internal) (re_match_2_internal, re_match_2_internal, re_match_2_internal): Giving in to popular pressure to shut up the compiler with casts. 2000-10-25 Stefan Monnier * regex.c: More `unsigned char' -> `re_char' changes. Also change several `int' into `re_wchar_t'. (PATTERN_STACK_EMPTY, PUSH_PATTERN_OP, POP_PATTERN_OP): Remove. (PUSH_FAILURE_POINTER): Don't cast any more. (POP_FAILURE_REG_OR_COUNT): Remove the cast that strips `const'. We want GCC to complain, since this piece of code makes re_match non-reentrant, which *should* be fixed. (GET_BUFFER_SPACE): Use size_t rather than unsigned long. (EXTEND_BUFFER): Use RETALLOC. (SET_LIST_BIT): Don't cast. (re_wchar_t): New type. (re_iswctype, re_wctype_to_bit): Make it crystal clear to GCC that those two functions will always properly return. (IMMEDIATE_QUIT_CHECK): Cast to void. (analyse_first): Use recursion rather than an explicit stack. (re_compile_fastmap): Can't fail anymore. (re_search_2): Don't check re_compile_fastmap for failure. (PUSH_NUMBER): Renamed from PUSH_FAILURE_COUNT. Now also sets the new value (passed in a new argument). (re_match_2_internal): Use it. Also, use a new var `reg' of type size_t when looping through regs rather than reuse the inappropriate `mcnt'. 2000-10-24 Andrew Innes * regex.c (IMMEDIATE_QUIT_CHECK): New macro, which does QUIT on NT-Emacs only. (re_match_2_internal): Use IMMEDIATE_QUIT_CHECK instead of QUIT, so that re_search functions only quit when callers expect them to. 2000-10-24 Kenichi Handa * regex.c (regex_compile): Change the way of handling a range from a char less than 256 to a char not less than 256. 2000-10-15 Stefan Monnier * regex.c (WIDE_CHAR_SUPPORT): Define if _LIBC as well.
