2002-04-07 Andrew Cagney <ac131313@redhat.com> From 2002-03-05 Scott Pakin <pakin@uiuc.edu> * mmap-sup.c (MAP_PRIVATE_OR_SHARED): Define. (__mmalloc_mmap_morecore): Use. (__mmalloc_remap_core): Use. 2000-05-17 Eli Zaretskii <eliz@is.elta.co.il> * Makefile.in (install-info): Make sure $(infodir) exists. Run install-info program on the installed Info files. 2000-03-20 Eli Zaretskii <eliz@is.elta.co.il> * Makefile.in (install): Append "n", not ".n" to libmmalloc.a, since the latter loses on DOS 8+3 filesystems. Mon Feb 28 10:33:51 2000 Andrew Cagney <cagney@b1.cygnus.com> * MAINTAINERS: New file. 2000-02-18 Frank Ch. Eigler <fche@redhat.com> From Jason "crash" Molenda <jsm@cygnus.com>: * configure.in: Check for getpagesize declaration. * mvmalloc.c, mmap-sup.c: Conditionally declare getpagesize. * configure: Regenerated. Fri Feb 18 11:42:21 2000 Andrew Cagney <cagney@b1.cygnus.com> * configure.in: Check for <unistd.h>. * configure: Regenerate. From 2000-02-17 RodneyBrown@pmsc.com: * mm.c, attach.c, mmap-sup.c, sbrk-sup.c: Include <unistd.h> for sbrk and lseek declarations. Update copyright. 2000-02-04 Kevin Buettner (kevinb@cygnus.com) * acinclude.m4, aclocal.m4: New files. * configure.in (sbrk): Use BFD_NEED_DECLARATION to test for presence of a suitable declaration in the system headers. * configure: Regenerated. * sbrk-sup.c (sbrk): Ifdef'd with NEED_DECLARATION_SBRK. 1999-01-04 Jason Molenda (jsm@bugshack.cygnus.com) * configure.in: Requires autoconf 2.12.1 or higher. * configure: Regenerated. 1998-07-24 Jim Blandy <jimb@zwingli.cygnus.com> * mcalloc.c: #include <sys/types.h> before <string.h>. HP/UX 11.0 needs this. Thu Apr 23 12:19:22 1998 Philippe De Muyter <phdm@macqel.be> * mmalloc.h: Include sys/types.h and stdio.h #ifndef HAVE_STDDEF_H. * mmprivate.h: Do not handle HAVE_STDDEF_H here, since we include mmalloc.h. Tue Mar 24 17:07:02 1998 Stu Grossman <grossman@bhuna.cygnus.co.uk> * Makefile.in: Get SHELL from configure. * configure: Regenerate with autoconf 2.12.1 to fix shell issues for NT native builds. Mon Feb 7 13:06:45 1997 Philippe De Muyter <phdm@macqel.be> * mmalloc/detach.c: Do not include fcntl.h. Thu Aug 28 13:15:07 1997 Andrew Cagney <cagney@b1.cygnus.com> * mrealloc.c (realloc): Store result in local variable before returning it. Makes debugging much easier at negligible cost. Tue Feb 4 16:30:59 1997 Ian Lance Taylor <ian@cygnus.com> * mvalloc.c (cache_pagesize): Rename from pagesize, so that if we are building mm.o, it does not conflict with the variable of the same name in mmap-sup.c. Sat Dec 28 12:48:32 1996 Fred Fish <fnf@cygnus.com> * Makefile.in (mm.o): New target that combines all the functions into a single object module. This avoids client programs picking up part of the allocation routines from mmalloc and part from libc, which can lead to undefined behavior. (CFILES): Add mm.c (TARGETOBJS): Define to be either the individual objects or the single combined object. (TARGETLIB): Create the archive using TARGETOBJS. * mm.c: New file that simply #includes the other source C files. Thu Oct 3 15:45:23 1996 Jason Molenda (crash@godzilla.cygnus.co.jp) * Makefile.in (maintainer-clean): Depend on distclean, remove duplication. Tue Sep 10 17:52:06 1996 Fred Fish <fnf@cygnus.com> * mmcheck.c (checkhdr): Add prototype. (mfree_check): Ditto. (mmalloc_check): Ditto. (mrealloc_check): Ditto. * mmtrace.c (tr_break): Ditto. (tr_freehook): Ditto. (tr_mallochook): Ditto. (tr_reallochook): Ditto. * sbrk-sup.c (sbrk_morecore): Ditto. Wed Sep 4 18:02:45 1996 Stu Grossman (grossman@critters.cygnus.com) * configure configure.in: Don't default CC to cc. It causes problems when starting a compile in the mmalloc directory. Wed Jul 24 00:53:34 1996 Fred Fish <fnf@cygnus.com> * mmalloc.h (mmalloc_findbase): Add prototype. Fri Jul 12 18:35:34 1996 Fred Fish <fnf@cygnus.com> * mmap-sup.c (mmalloc_findbase): Change to not require /dev/zero if MMAP_ANONYMOUS is available. Wed Jul 10 23:53:42 1996 Fred Fish <fnf@cygnus.com> * detach.c (mmalloc_detach): Fix bug in computation of negative brk value. * mmcheck.c (mmcheckf): Renamed from mmcheck and new FORCE argument added. Replaced hack that always allowed checking routines to be installed and enforce restriction that they have to be installed prior to allocating any memory on the used heap or the FORCE argument has to be non-NULL. (mmcheck): New function that calls mmcheckf with FORCE set to zero, for backwards compatibility. * mmalloc.c (malloc): Store result in local variable before returning it. Makes debugging much easier at negligible cost. * mmalloc.h (mmcheckf): Declare. * attach.c (reuse): Call mmcheckf rather than mmcheck. * mmap-sup.c (__mmalloc_mmap_morecore): Improve to allow mmap to select a base mapping address if none is otherwise given. (mmalloc_findbase): New function that user can call to find an available mapping address of a given size. Tue Jun 25 22:54:06 1996 Jason Molenda (crash@godzilla.cygnus.co.jp) * Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir): Use autoconf-set values. (docdir): Removed. * configure.in (AC_PREREQ): autoconf 2.5 or higher. * configure: Rebuilt. Tue May 28 13:51:22 1996 Fred Fish <fnf@cygnus.com> From: Thomas A Peterson <tap@src.honeywell.com> * Makefile.in (install-info): Apply patch to install mmalloc.info from srcdir if not found in build dir. Sun Apr 7 20:55:30 1996 Fred Fish <fnf@rtl.cygnus.com> From: Miles Bader <miles@gnu.ai.mit.edu> * configure.in: Use AC_CHECK_TOOL to find AR & RANLIB. * configure: Regenerate with autoconf. * Makefile.in: Use AR set by configure substitution. Fri Mar 29 09:57:36 1996 Fred Fish <fnf@cygnus.com> * mmalloc.h (mmtrace): Add prototype. Sat Feb 3 12:41:00 1996 Fred Fish <fnf@cygnus.com> From H.J. Lu (hjl@gnu.ai.mit.edu): * mvalloc.c (valloc): new. * mmemalign.c: Allocate (SIZE + ALIGNMENT - 1) and then trim if possible. (memalign): don't put the node on the _aligned_blocks list more than once. Mon Nov 20 12:04:32 1995 Fred Fish <fnf@cygnus.com> * Makefile.in (OFILES): Make objects depend upon Makefile, since Makefile sets DEFS which can definitely affect how objects are to be compiled. Mon Nov 6 14:12:13 1995 Jason Molenda (crash@phydeaux.cygnus.com) * configure.in (AC_CHECK_HEADERS): add limits.h. (AC_HEADER_STDC): remove. * mmalloc.h: document necessity of defining size_t before including mmalloc.h. * mmprivate.h: add check for limits.h, remove definition of NULL and size_t. Sun Nov 5 00:27:36 1995 Jason Molenda (crash@phydeaux.cygnus.com) * configure.in: AC_CHECK_HEADERS, not AC_CHECK_HEADER. Sun Nov 5 00:14:13 1995 Jason Molenda (crash@phydeaux.cygnus.com) * configure.in: add check for stddef.h * mmalloc.h: include stddef.h if HAVE_STDDEF_H is defined. Sat Nov 4 19:10:13 1995 Jason Molenda (crash@phydeaux.cygnus.com) * configure.in: add AC_HEADER_STDC check. * mmalloc.h: check if STDC_HEADERS instead of __STDC__. * mmprivate.h: check if STDC_HEADERS instead of __STDC__. Tue Oct 24 13:17:44 1995 Stan Shebs <shebs@andros.cygnus.com> * mmprivate.h: Remove declarations (PTR, etc) that are already provided by ansidecl.h, include mmalloc.h earlier in file. Tue Oct 10 11:04:47 1995 Fred Fish <fnf@cygnus.com> * Makefile.in (BISON): Remove macro. Wed Sep 20 12:51:13 1995 Ian Lance Taylor <ian@cygnus.com> * Makefile.in (maintainer-clean): New target, synonym for realclean. Add GNU standard maintainer-clean echos.

Conklin <jtc@rtl.cygnus.com> * Makefile.in (Makefile): Added config.status to dependency list. (config.status): New target. Fri May 5 15:17:53 1995 J.T. Conklin <jtc@rtl.cygnus.com> * mmap-sup.c: Removed munmap prototype. Some systems have a slightly different prototype. Wed May 3 17:18:13 1995 J.T. Conklin <jtc@rtl.cygnus.com> * Makefile.in, configure.in: Converted to use autoconf. * configure: New file, generated with autoconf 2.3. * config/{mh-go32, mh-irix, mh-ncr3000, mh-sunos4, mh-sysv4}: Removed. Thu Nov 3 23:55:21 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com) * Makefile.in (install-info): Name destination file correctly, rather than using undefined shell variable. Fri Oct 28 16:46:58 1994 Stan Shebs (shebs@andros.cygnus.com) * mmprivate.h: New file, was mmalloc.h. (mmalloc.h): Include. * mmalloc.h: Remove all but declarations of mmalloc functions.
