-
- * rx.c: applied patches from H J Lu to unrot BSD compatibility
- code.
-
- Mon Aug 29 16:48:57 1994 Ian Lance Taylor (ian@sanguine.cygnus.com)
-
- * Makefile.in (AR_FLAGS): Define.
- (librx.a): Use $(AR) and $(AR_FLAGS).

- Fri Aug 26 11:37:36 1994 Ian Lance Taylor (ian@cygnus.com)
-
- * configure.in: Call AC_PROG_CPP explicitly.
- * configure: Rebuilt.
-
- Thu Aug 25 18:19:47 1994 Tom Lord (lord@x1.cygnus.com)
-
- * rx.[ch], configure.in: use __const__ instead of
- AC_CONST. Only include stdio once. Don't check
- for memory.h.
-
- Tue Aug 16 12:12:01 1994 Tom Lord (lord@x1.cygnus.com)
-
- * rx.[ch]: LGPL instead of GPL

- handle the case that we're searching backwards.

-
- * rx.c (re_rx_search): New function, exports rx_search.
-
- * Makefile.in (clean): Also remove librx.a.
-
- Fri Jun 3 12:16:45 1994 Tom Lord (lord@x1.cygnus.com)
-
- * rx.c(re_search_2_fetch_char): fixed a bug that caused it to
- ignore OFFSET.

-
- * rx.[ch]: From: Michael Rendell <michael@maple.cs.mun.ca>
-
- ``The problem seems to lie in the casting between pointers and
- integers (pointers on the alpha are 64 bits, ints 32 bits, longs
- 64 bits). The core dump happens in rx_compactify_nfa(), in the
- first for loop in the while(eclose) loop -- rx_hash_find() returns
- 0, which is dereferenced.''
-
- The patch changed the type of rx_hash_masks to long and
- also a use of `int' to hold a side effect in rx_search.
-
- Sat May 14 00:45:14 1994 Tom Lord (lord@x1.cygnus.com)
-
- * rx.c, rx.h: rearranged all the code
- so that all the rx functions can be exported
- or hidden (define RX_WANT_RX_DEFS when compiling
- and when including rx.h).
-
- Wed May 11 01:15:56 1994 Tom Lord (lord@rtl.cygnus.com)
-
- * rx.c, rx.h: added rx_search -- searching in
- arbitrarily fragmented strings, continuation support.
-
- Wed May 4 13:56:55 1994 Tom Lord (lord@rtl.cygnus.com)
-
- * rx.c, rx.h: Started independent maintainence
- of these.
-
- ------ version 0.04 ------
-
- Fri May 13 02:31:13 1994 Tom Lord (lord@x1.cygnus.com)
-
- * rx.c: eliminated the weirdo custom allocators.
- Fixed some bugs (but lost the ChangeLog entries).
-
- Wed May 11 06:09:31 1994 Chip Salzenberg (chip@fin.uucp)
-
- * rx.c (rx_superstate_eclosure_union): Always return a value.
-
- ------ version 0.03 ------
- Fri Aug 6 01:57:28 1993 Tom Lord (lord@unix1.andrew.cmu.edu)
-
- * rx.c (re_search_2): sped up the fastmap search a little
- to as to not be slower than regex.c on simple patterns.
- Rx will still lose by a couple instructions in some degenerate
- cases but mostly will win.
-
- Thu Aug 5 11:39:57 1993 Tom Lord (lord@thisbe.weh.andrew.cmu.edu)
-
- * rx.c (re_search_2 & compilation front-ends): cache the starting
- superset of super-nfa's so that it isn't necessary to do an
- eclosure union for every call to re_search_2.
-
- * rx.c (re_search_2): (from Eric Backus) arrange to call
- alloca(0) from a shallower stack frame than re_search_2
- if callling it at all.
-
- This could use a better cpp test. Right now, an extra function
- call is added to re_search_2 unles __GNUC__ is defined. If
- there were something like _HAVE_LOSER_ALLOCA_....
-
- * rx.c (rx_compile, re_search_2, several new fns):
- changed the order of side effect lists so that possible
- futures that begin with complex effects more to the right
- are explored after futures more to the left. Added
- a noop complex effect to alts and stars to guarantee
- they are explored in the right order. An optimization
- after the parse removes some from the alts (and not all
- stars get them in the first place). Changed the `best
- match' criterea -- now that possible futures are ordered
- posixly, we only want to check the length of the match.
- For a given length, the best subexpression partitioning
- is the first one found.
-
- A side effect of this is that Rx will always return the
- same register assignements for a given regexp/input text.
- Bummer :-) / 2.

-
- ------ version 0.02 ------
-
- ed Jul 21 13:10:56 1993 Tom Lord (lord@unix8.andrew.cmu.edu)
-
- * rx.c (re_search_2): elaborated on the rule for picking the
- best match so that the lengths of subexpressions are taken
- into account. This is for Posix compatability.
-
-
- ------ version 0.01 ------
-
- Sun Jun 13 17:20:35 1993 Tom Lord (lord@tsunami.ucc.andrew.cmu.edu)
-
- * This is the first release of rx.c. Although some of the code
- is derived from regex.c, there is not much continuity between
- the two implementations.
