  12
  13         From 2000-02-17 RodneyBrown@pmsc.com:
  14         * mm.c, attach.c, mmap-sup.c, sbrk-sup.c: Include <unistd.h> for
  15         sbrk and lseek declarations.  Update copyright.
  16
  17 2000-02-04  Kevin Buettner  (kevinb@cygnus.com)
  18
  19         * acinclude.m4, aclocal.m4: New files.
  20         * configure.in (sbrk): Use BFD_NEED_DECLARATION to test for
  21         presence of a suitable declaration in the system headers.
  22         * configure: Regenerated.
  23         * sbrk-sup.c (sbrk): Ifdef'd with NEED_DECLARATION_SBRK.
  24

  29
  30 1998-07-24  Jim Blandy  <jimb@zwingli.cygnus.com>
  31
  32         * mcalloc.c: #include <sys/types.h> before <string.h>.  HP/UX 11.0
  33         needs this.
  34
  35 Thu Apr 23 12:19:22 1998  Philippe De Muyter  <phdm@macqel.be>
  36
  37         * mmalloc.h: Include sys/types.h and stdio.h #ifndef HAVE_STDDEF_H.
  38         * mmprivate.h: Do not handle HAVE_STDDEF_H here, since we include
  39         mmalloc.h.
  40
  41 Tue Mar 24 17:07:02 1998  Stu Grossman  <grossman@bhuna.cygnus.co.uk>
  42
  43         * Makefile.in:  Get SHELL from configure.

  45         NT native builds.
  46

  48
  49         * mmalloc/detach.c: Do not include fcntl.h.
  50
  51 Thu Aug 28 13:15:07 1997  Andrew Cagney  <cagney@b1.cygnus.com>
  52
  53         * mrealloc.c (realloc): Store result in local variable before
  54         returning it.  Makes debugging much easier at negligible cost.
  55
  56 Tue Feb  4 16:30:59 1997  Ian Lance Taylor  <ian@cygnus.com>
  57
  58         * mvalloc.c (cache_pagesize): Rename from pagesize, so that if we
  59         are building mm.o, it does not conflict with the variable of the
  60         same name in mmap-sup.c.
  61
  62 Sat Dec 28 12:48:32 1996  Fred Fish  <fnf@cygnus.com>
  63
  64         * Makefile.in (mm.o): New target that combines all the functions
  65         into a single object module.  This avoids client programs picking
  66         up part of the allocation routines from mmalloc and part from libc,
  67         which can lead to undefined behavior.
  68         (CFILES): Add mm.c
  69         (TARGETOBJS): Define to be either the individual objects or the
  70         single combined object.
  71         (TARGETLIB): Create the archive using TARGETOBJS.
  72         * mm.c: New file that simply #includes the other source C files.
  73
  74 Thu Oct  3 15:45:23 1996  Jason Molenda  (crash@godzilla.cygnus.co.jp)
  75
  76         * Makefile.in (maintainer-clean): Depend on distclean, remove
  77         duplication.
  78
  79 Tue Sep 10 17:52:06 1996  Fred Fish  <fnf@cygnus.com>
  80
  81         * mmcheck.c (checkhdr): Add prototype.
  82         (mfree_check): Ditto.
  83         (mmalloc_check): Ditto.
  84         (mrealloc_check): Ditto.
  85         * mmtrace.c (tr_break): Ditto.
  86         (tr_freehook): Ditto.
  87         (tr_mallochook): Ditto.
  88         (tr_reallochook): Ditto.
  89         * sbrk-sup.c (sbrk_morecore): Ditto.
  90
  91 Wed Sep  4 18:02:45 1996  Stu Grossman  (grossman@critters.cygnus.com)
  92
  93         * configure configure.in:  Don't default CC to cc.  It causes problems
  94         when starting a compile in the mmalloc directory.
  95
  96 Wed Jul 24 00:53:34 1996  Fred Fish  <fnf@cygnus.com>
  97
  98         * mmalloc.h (mmalloc_findbase): Add prototype.
  99
 100 Fri Jul 12 18:35:34 1996  Fred Fish  <fnf@cygnus.com>
 101
 102         * mmap-sup.c (mmalloc_findbase): Change to not require /dev/zero
 103         if MMAP_ANONYMOUS is available.
 104
 105 Wed Jul 10 23:53:42 1996  Fred Fish  <fnf@cygnus.com>
 106
 107         * detach.c (mmalloc_detach): Fix bug in computation of negative
 108         brk value.
 109         * mmcheck.c (mmcheckf): Renamed from mmcheck and new FORCE argument
 110         added.  Replaced hack that always allowed checking routines to be
 111         installed and enforce restriction that they have to be installed
 112         prior to allocating any memory on the used heap or the FORCE argument
 113         has to be non-NULL.
 114         (mmcheck): New function that calls mmcheckf with FORCE set to zero,
 115         for backwards compatibility.
 116         * mmalloc.c (malloc): Store result in local variable before
 117         returning it.  Makes debugging much easier at negligible cost.
 118         * mmalloc.h (mmcheckf): Declare.
 119         * attach.c (reuse): Call mmcheckf rather than mmcheck.
 120         * mmap-sup.c (__mmalloc_mmap_morecore): Improve to allow mmap
 121         to select a base mapping address if none is otherwise given.
 122         (mmalloc_findbase): New function that user can call to find
 123         an available mapping address of a given size.
 124
 125 Tue Jun 25 22:54:06 1996  Jason Molenda  (crash@godzilla.cygnus.co.jp)
 126
 127         * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir):
 128         Use autoconf-set values.
 129         (docdir): Removed.
 130         * configure.in (AC_PREREQ): autoconf 2.5 or higher.
 131         * configure: Rebuilt.
 132
 133 Tue May 28 13:51:22 1996  Fred Fish  <fnf@cygnus.com>
 134
 135         From: Thomas A Peterson <tap@src.honeywell.com>
 136         * Makefile.in (install-info): Apply patch to install
 137         mmalloc.info from srcdir if not found in build dir.
 138
 139 Sun Apr  7 20:55:30 1996  Fred Fish  <fnf@rtl.cygnus.com>
 140
 141         From: Miles Bader  <miles@gnu.ai.mit.edu>
 142         * configure.in: Use AC_CHECK_TOOL to find AR & RANLIB.
 143         * configure: Regenerate with autoconf.
 144         * Makefile.in: Use AR set by configure substitution.
 145

 147
 148         * mmalloc.h (mmtrace): Add prototype.
 149
 150 Sat Feb  3 12:41:00 1996  Fred Fish  <fnf@cygnus.com>
 151
 152         From H.J. Lu (hjl@gnu.ai.mit.edu):
 153         * mvalloc.c (valloc): new.
 154         * mmemalign.c: Allocate (SIZE + ALIGNMENT - 1) and then trim
 155         if possible.
 156         (memalign): don't put the node on the _aligned_blocks list more
 157         than once.
 158
 159 Mon Nov 20 12:04:32 1995  Fred Fish  <fnf@cygnus.com>
 160
 161         * Makefile.in (OFILES): Make objects depend upon Makefile,
 162         since Makefile sets DEFS which can definitely affect how
 163         objects are to be compiled.
 164
 165 Mon Nov  6 14:12:13 1995  Jason Molenda  (crash@phydeaux.cygnus.com)

 174         NULL and size_t.

 176 Sun Nov  5 00:27:36 1995  Jason Molenda  (crash@phydeaux.cygnus.com)
 177
