  14

  52
  53         * mcalloc.c: #include <sys/types.h> before <string.h>.  HP/UX 11.0

  55
  56 Thu Apr 23 12:19:22 1998  Philippe De Muyter  <phdm@macqel.be>
  57
  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

  61
  62 Tue Mar 24 17:07:02 1998  Stu Grossman  <grossman@bhuna.cygnus.co.uk>
  63

  69
  70         * mmalloc/detach.c: Do not include fcntl.h.
  71
  72 Thu Aug 28 13:15:07 1997  Andrew Cagney  <cagney@b1.cygnus.com>
  73
  74         * mrealloc.c (realloc): Store result in local variable before

  76
  77 Tue Feb  4 16:30:59 1997  Ian Lance Taylor  <ian@cygnus.com>
  78
  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.
  82
  83 Sat Dec 28 12:48:32 1996  Fred Fish  <fnf@cygnus.com>
  84
  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.
  89         (CFILES): Add mm.c
  90         (TARGETOBJS): Define to be either the individual objects or the
  91         single combined object.
  92         (TARGETLIB): Create the archive using TARGETOBJS.
  93         * mm.c: New file that simply #includes the other source C files.
  94
  95 Thu Oct  3 15:45:23 1996  Jason Molenda  (crash@godzilla.cygnus.co.jp)
  96
  97         * Makefile.in (maintainer-clean): Depend on distclean, remove
  98         duplication.
  99
 100 Tue Sep 10 17:52:06 1996  Fred Fish  <fnf@cygnus.com>
 101
 102         * mmcheck.c (checkhdr): Add prototype.
 103         (mfree_check): Ditto.
 104         (mmalloc_check): Ditto.
 105         (mrealloc_check): Ditto.
 106         * mmtrace.c (tr_break): Ditto.
 107         (tr_freehook): Ditto.
 108         (tr_mallochook): Ditto.
 109         (tr_reallochook): Ditto.
 110         * sbrk-sup.c (sbrk_morecore): Ditto.
 111
 112 Wed Sep  4 18:02:45 1996  Stu Grossman  (grossman@critters.cygnus.com)
 113
 114         * configure configure.in:  Don't default CC to cc.  It causes problems
 115         when starting a compile in the mmalloc directory.
 116
 117 Wed Jul 24 00:53:34 1996  Fred Fish  <fnf@cygnus.com>
 118
 119         * mmalloc.h (mmalloc_findbase): Add prototype.
 120
 121 Fri Jul 12 18:35:34 1996  Fred Fish  <fnf@cygnus.com>
 122
 123         * mmap-sup.c (mmalloc_findbase): Change to not require /dev/zero
 124         if MMAP_ANONYMOUS is available.
 125
 126 Wed Jul 10 23:53:42 1996  Fred Fish  <fnf@cygnus.com>
 127
 128         * detach.c (mmalloc_detach): Fix bug in computation of negative
 129         brk value.
 130         * mmcheck.c (mmcheckf): Renamed from mmcheck and new FORCE argument
 131         added.  Replaced hack that always allowed checking routines to be
 132         installed and enforce restriction that they have to be installed
 133         prior to allocating any memory on the used heap or the FORCE argument
 134         has to be non-NULL.
 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.
 145
 146 Tue Jun 25 22:54:06 1996  Jason Molenda  (crash@godzilla.cygnus.co.jp)
 147
 148         * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir):
 149         Use autoconf-set values.
 150         (docdir): Removed.
 151         * configure.in (AC_PREREQ): autoconf 2.5 or higher.
 152         * configure: Rebuilt.
 153
 154 Tue May 28 13:51:22 1996  Fred Fish  <fnf@cygnus.com>
 155
 156         From: Thomas A Peterson <tap@src.honeywell.com>
 157         * Makefile.in (install-info): Apply patch to install
 158         mmalloc.info from srcdir if not found in build dir.
 159
 160 Sun Apr  7 20:55:30 1996  Fred Fish  <fnf@rtl.cygnus.com>
 161
 162         From: Miles Bader  <miles@gnu.ai.mit.edu>
 163         * configure.in: Use AC_CHECK_TOOL to find AR & RANLIB.
 164         * configure: Regenerate with autoconf.
 165         * Makefile.in: Use AR set by configure substitution.
 166

 168
 169         * mmalloc.h (mmtrace): Add prototype.
 170
 171 Sat Feb  3 12:41:00 1996  Fred Fish  <fnf@cygnus.com>
 172
 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
 176         if possible.
 177         (memalign): don't put the node on the _aligned_blocks list more
 178         than once.
 179
 180 Mon Nov 20 12:04:32 1995  Fred Fish  <fnf@cygnus.com>
 181
 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.
 185
 186 Mon Nov  6 14:12:13 1995  Jason Molenda  (crash@phydeaux.cygnus.com)

 194         * mmprivate.h: add check for limits.h, remove definition of
 195         NULL and size_t.

 197 Sun Nov  5 00:27:36 1995  Jason Molenda  (crash@phydeaux.cygnus.com)
 198
