6 2000-03-20 Eli Zaretskii <eliz@is.elta.co.il>
8 * Makefile.in (install): Append "n", not ".n" to libmmalloc.a,

13 * MAINTAINERS: New file.

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

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

70 Tue Feb 4 16:30:59 1997 Ian Lance Taylor <ian@cygnus.com>

73 are building mm.o, it does not conflict with the variable of the
74 same name in mmap-sup.c.
76 Sat Dec 28 12:48:32 1996 Fred Fish <fnf@cygnus.com>
78 * Makefile.in (mm.o): New target that combines all the functions
79 into a single object module. This avoids client programs picking
80 up part of the allocation routines from mmalloc and part from libc,
81 which can lead to undefined behavior.
83 (TARGETOBJS): Define to be either the individual objects or the
84 single combined object.
85 (TARGETLIB): Create the archive using TARGETOBJS.

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

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

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

166 From H.J. Lu (hjl@gnu.ai.mit.edu):
167 * mvalloc.c (valloc): new.
168 * mmemalign.c: Allocate (SIZE + ALIGNMENT - 1) and then trim

173 Mon Nov 20 12:04:32 1995 Fred Fish <fnf@cygnus.com>
175 * Makefile.in (OFILES): Make objects depend upon Makefile,
176 since Makefile sets DEFS which can definitely affect how
177 objects are to be compiled.

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