11 install-info program on the installed Info files.
13 2000-03-20 Eli Zaretskii <eliz@is.elta.co.il>
15 * Makefile.in (install): Append "n", not ".n" to libmmalloc.a,
16 since the latter loses on DOS 8+3 filesystems.
18 Mon Feb 28 10:33:51 2000 Andrew Cagney <cagney@b1.cygnus.com>
20 * MAINTAINERS: New file.
22 2000-02-18 Frank Ch. Eigler <fche@redhat.com>

42 presence of a suitable declaration in the system headers.
43 * configure: Regenerated.
44 * sbrk-sup.c (sbrk): Ifdef'd with NEED_DECLARATION_SBRK.
46 1999-01-04 Jason Molenda (jsm@bugshack.cygnus.com)
48 * configure.in: Requires autoconf 2.12.1 or higher.
49 * configure: Regenerated.
51 1998-07-24 Jim Blandy <jimb@zwingli.cygnus.com>
53 * mcalloc.c: #include <sys/types.h> before <string.h>. HP/UX 11.0
56 Thu Apr 23 12:19:22 1998 Philippe De Muyter <phdm@macqel.be>
58 * mmalloc.h: Include sys/types.h and stdio.h #ifndef HAVE_STDDEF_H.
59 * mmprivate.h: Do not handle HAVE_STDDEF_H here, since we include

72 Thu Aug 28 13:15:07 1997 Andrew Cagney <cagney@b1.cygnus.com>

77 Tue Feb 4 16:30:59 1997 Ian Lance Taylor <ian@cygnus.com>
79 * mvalloc.c (cache_pagesize): Rename from pagesize, so that if we
80 are building mm.o, it does not conflict with the variable of the
81 same name in mmap-sup.c.

85 * Makefile.in (mm.o): New target that combines all the functions
86 into a single object module. This avoids client programs picking
87 up part of the allocation routines from mmalloc and part from libc,
88 which can lead to undefined behavior.
90 (TARGETOBJS): Define to be either the individual objects or the
91 single combined object.
92 (TARGETLIB): Create the archive using TARGETOBJS.

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

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

128 * detach.c (mmalloc_detach): Fix bug in computation of negative
130 * mmcheck.c (mmcheckf): Renamed from mmcheck and new FORCE argument
131 added. Replaced hack that always allowed checking routines to be

133 prior to allocating any memory on the used heap or the FORCE argument
135 (mmcheck): New function that calls mmcheckf with FORCE set to zero,
136 for backwards compatibility.
137 * mmalloc.c (malloc): Store result in local variable before
138 returning it. Makes debugging much easier at negligible cost.
139 * mmalloc.h (mmcheckf): Declare.
140 * attach.c (reuse): Call mmcheckf rather than mmcheck.
141 * mmap-sup.c (__mmalloc_mmap_morecore): Improve to allow mmap
142 to select a base mapping address if none is otherwise given.
143 (mmalloc_findbase): New function that user can call to find
144 an available mapping address of a given size.
146 Tue Jun 25 22:54:06 1996 Jason Molenda (crash@godzilla.cygnus.co.jp)
148 * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir):
149 Use autoconf-set values.
151 * configure.in (AC_PREREQ): autoconf 2.5 or higher.
152 * configure: Rebuilt.

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

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

442 * detach.c (mmalloc_detach): Arg should be PTR, not void *.
