1 2000-03-20 Eli Zaretskii <eliz@is.elta.co.il>
3 * Makefile.in (install): Append "n", not ".n" to libmmalloc.a,

8 * MAINTAINERS: New file.
10 2000-02-18 Frank Ch. Eigler <fche@redhat.com>

24 sbrk and lseek declarations. Update copyright.
26 2000-02-04 Kevin Buettner (kevinb@cygnus.com)
28 * acinclude.m4, aclocal.m4: New files.
29 * configure.in (sbrk): Use BFD_NEED_DECLARATION to test for
30 presence of a suitable declaration in the system headers.
31 * configure: Regenerated.
32 * sbrk-sup.c (sbrk): Ifdef'd with NEED_DECLARATION_SBRK.
34 1999-01-04 Jason Molenda (jsm@bugshack.cygnus.com)
36 * configure.in: Requires autoconf 2.12.1 or higher.
37 * configure: Regenerated.
39 1998-07-24 Jim Blandy <jimb@zwingli.cygnus.com>
41 * mcalloc.c: #include <sys/types.h> before <string.h>. HP/UX 11.0
44 Thu Apr 23 12:19:22 1998 Philippe De Muyter <phdm@macqel.be>
46 * mmalloc.h: Include sys/types.h and stdio.h #ifndef HAVE_STDDEF_H.
47 * mmprivate.h: Do not handle HAVE_STDDEF_H here, since we include
50 Tue Mar 24 17:07:02 1998 Stu Grossman <grossman@bhuna.cygnus.co.uk>
52 * Makefile.in: Get SHELL from configure.
53 * configure: Regenerate with autoconf 2.12.1 to fix shell issues for

58 * mmalloc/detach.c: Do not include fcntl.h.
60 Thu Aug 28 13:15:07 1997 Andrew Cagney <cagney@b1.cygnus.com>

65 Tue Feb 4 16:30:59 1997 Ian Lance Taylor <ian@cygnus.com>
67 * mvalloc.c (cache_pagesize): Rename from pagesize, so that if we
68 are building mm.o, it does not conflict with the variable of the
69 same name in mmap-sup.c.
71 Sat Dec 28 12:48:32 1996 Fred Fish <fnf@cygnus.com>
73 * Makefile.in (mm.o): New target that combines all the functions
74 into a single object module. This avoids client programs picking
75 up part of the allocation routines from mmalloc and part from libc,
76 which can lead to undefined behavior.
78 (TARGETOBJS): Define to be either the individual objects or the
79 single combined object.
80 (TARGETLIB): Create the archive using TARGETOBJS.

100 Wed Sep 4 18:02:45 1996 Stu Grossman (grossman@critters.cygnus.com)
102 * configure configure.in: Don't default CC to cc. It causes problems
103 when starting a compile in the mmalloc directory.
105 Wed Jul 24 00:53:34 1996 Fred Fish <fnf@cygnus.com>
107 * mmalloc.h (mmalloc_findbase): Add prototype.

111 * mmap-sup.c (mmalloc_findbase): Change to not require /dev/zero
112 if MMAP_ANONYMOUS is available.

116 * detach.c (mmalloc_detach): Fix bug in computation of negative
118 * mmcheck.c (mmcheckf): Renamed from mmcheck and new FORCE argument
119 added. Replaced hack that always allowed checking routines to be
120 installed and enforce restriction that they have to be installed
121 prior to allocating any memory on the used heap or the FORCE argument
123 (mmcheck): New function that calls mmcheckf with FORCE set to zero,
124 for backwards compatibility.
125 * mmalloc.c (malloc): Store result in local variable before
126 returning it. Makes debugging much easier at negligible cost.
127 * mmalloc.h (mmcheckf): Declare.
128 * attach.c (reuse): Call mmcheckf rather than mmcheck.
129 * mmap-sup.c (__mmalloc_mmap_morecore): Improve to allow mmap
130 to select a base mapping address if none is otherwise given.
131 (mmalloc_findbase): New function that user can call to find
132 an available mapping address of a given size.
134 Tue Jun 25 22:54:06 1996 Jason Molenda (crash@godzilla.cygnus.co.jp)
136 * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir):
137 Use autoconf-set values.
139 * configure.in (AC_PREREQ): autoconf 2.5 or higher.
140 * configure: Rebuilt.

159 Sat Feb 3 12:41:00 1996 Fred Fish <fnf@cygnus.com>
161 From H.J. Lu (hjl@gnu.ai.mit.edu):
162 * mvalloc.c (valloc): new.
163 * mmemalign.c: Allocate (SIZE + ALIGNMENT - 1) and then trim
165 (memalign): don't put the node on the _aligned_blocks list more
168 Mon Nov 20 12:04:32 1995 Fred Fish <fnf@cygnus.com>
170 * Makefile.in (OFILES): Make objects depend upon Makefile,
171 since Makefile sets DEFS which can definitely affect how
172 objects are to be compiled.

176 * configure.in (AC_CHECK_HEADERS): add limits.h.
