| | | | | | | (re_match_failures): Reduce the larger value to 200000, and use whenever if MATCH_MAY_ALLOCATE. (MATCH_MAY_ALLOCATE): Don't consider REL_ALLOC when deciding whether to undef this.
* [! emacs]: #undef REL_ALLOC.Richard M. Stallman1995-05-061-0/+5
|
* (union fail_stack_elt): New union.Richard M. Stallman1995-05-021-26/+29

| | | | | | | | | | | | | | | | (WIDE_INT): Defined (two alternate definitions). (C_ALLOCA): Undef it, if __GNUC__. (REGEX_ALLOCATE_STACK, REGEX_REALLOCATE_STACK) (REGEX_FREE_STACK): New macros.

| | | | | | | | (PUSH_FAILURE_ITEM, POP_FAILURE_ITEM): Macros deleted. (PUSH_FAILURE_INT, POP_FAILURE_INT): New macros. (PUSH_FAILURE_POINTER, POP_FAILURE_POINTER): New macros. (re_match_2_internal): Rename label `succeed' to `succeed_label'.
* (SET_REGS_MATCHED): Enclose if-stmt in `do {...} while(0)'Jim Meyering1995-02-281-14/+16
| | | | | instead of using trailing `else' -- otherwise, gcc -Wall complains of `empty body in an else-statement'.

|
* (SET_REGS_MATCHED): Do nothing if set_regs_matched_done is 1.Richard M. Stallman1994-12-241-13/+28
| | | | | | | | | Set set_regs_matched_done to 1. (re_match_2_internal): New local var set_regs_matched_done. Set it to 0 when appropriate. (POP_FAILURE_POINT): Set set_regs_matched_done to 0. (re_match_2_internal, case duplicate): Call SET_REGS_MATCHED.
* [REG_UNSET_VALUE]: Define to the address of a static variable rather than toJim Meyering1994-12-111-1/+2
| | | | ((char *) -1). The latter got a warning on IRIX64.
* (gettext): Make sure this is always defined, even #if emacs.Karl Heuer1994-12-011-11/+8
| | | | (NULL): No need to #undef this anymore; Emacs uses NILP now.
* (re_compile_pattern, re_comp, regerror): Add gettext wrapper.Paul Eggert1994-11-291-16/+26
| | | | | | | | | | (re_error_msgid): Renamed from `re_error_msg', for consistency with other source files that declare arrays of message ids. Identifiers ending in `msgid' are special to to some prototype message-extracting utilities. Make "Success" be the 0th entry, so it can be extracted too. (re_comp): Replace "Memory exhausted" with re_error_msgid[REG_ESPACE], to aid message consistency.

* (re_comp, re_exec): Define this obsolete 4.2bsdPaul Eggert1994-10-261-3/+3
| | | | | interface only if the new feature test macro _REGEX_RE_COMP is defined. This avoids a clash with Cray YMP include files.
