19 sbrk and lseek declarations. Update copyright.
21 2000-02-04 Kevin Buettner (kevinb@cygnus.com)
23 * acinclude.m4, aclocal.m4: New files.
24 * configure.in (sbrk): Use BFD_NEED_DECLARATION to test for
25 presence of a suitable declaration in the system headers.
26 * configure: Regenerated.
27 * sbrk-sup.c (sbrk): Ifdef'd with NEED_DECLARATION_SBRK.
29 1999-01-04 Jason Molenda (jsm@bugshack.cygnus.com)
31 * configure.in: Requires autoconf 2.12.1 or higher.
32 * configure: Regenerated.
34 1998-07-24 Jim Blandy <jimb@zwingli.cygnus.com>
36 * mcalloc.c: #include <sys/types.h> before <string.h>. HP/UX 11.0
39 Thu Apr 23 12:19:22 1998 Philippe De Muyter <phdm@macqel.be>
41 * mmalloc.h: Include sys/types.h and stdio.h #ifndef HAVE_STDDEF_H.
42 * mmprivate.h: Do not handle HAVE_STDDEF_H here, since we include
45 Tue Mar 24 17:07:02 1998 Stu Grossman <grossman@bhuna.cygnus.co.uk>
47 * Makefile.in: Get SHELL from configure.
48 * configure: Regenerate with autoconf 2.12.1 to fix shell issues for

53 * mmalloc/detach.c: Do not include fcntl.h.
55 Thu Aug 28 13:15:07 1997 Andrew Cagney <cagney@b1.cygnus.com>
57 * mrealloc.c (realloc): Store result in local variable before
58 returning it. Makes debugging much easier at negligible cost.
60 Tue Feb 4 16:30:59 1997 Ian Lance Taylor <ian@cygnus.com>
62 * mvalloc.c (cache_pagesize): Rename from pagesize, so that if we
63 are building mm.o, it does not conflict with the variable of the
64 same name in mmap-sup.c.
66 Sat Dec 28 12:48:32 1996 Fred Fish <fnf@cygnus.com>
68 * Makefile.in (mm.o): New target that combines all the functions
69 into a single object module. This avoids client programs picking
70 up part of the allocation routines from mmalloc and part from libc,
71 which can lead to undefined behavior.
73 (TARGETOBJS): Define to be either the individual objects or the
74 single combined object.
75 (TARGETLIB): Create the archive using TARGETOBJS.
76 * mm.c: New file that simply #includes the other source C files.

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

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

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

361 * attach.c (reuse): Update the morecore field for reused mapped
362 regions to be correct for the current process.
