mmalloc/ChangeLog

   1 Fri Jul 12 18:35:34 1996  Fred Fish  <fnf@cygnus.com>
   2
   3         * mmap-sup.c (mmalloc_findbase): Change to not require /dev/zero
   4         if MMAP_ANONYMOUS is available.
   5
   6 Wed Jul 10 23:53:42 1996  Fred Fish  <fnf@cygnus.com>
   7
   8         * detach.c (mmalloc_detach): Fix bug in computation of negative
   9         brk value.
  10         * mmcheck.c (mmcheckf): Renamed from mmcheck and new FORCE argument
  11         added.  Replaced hack that always allowed checking routines to be
  12         installed and enforce restriction that they have to be installed
  13         prior to allocating any memory on the used heap or the FORCE argument
  14         has to be non-NULL.
  15         (mmcheck): New function that calls mmcheckf with FORCE set to zero,
  16         for backwards compatibility.
  17         * mmalloc.c (malloc): Store result in local variable before
  18         returning it.  Makes debugging much easier at negligible cost.
  19         * mmalloc.h (mmcheckf): Declare.
  20         * attach.c (reuse): Call mmcheckf rather than mmcheck.
  21         * mmap-sup.c (__mmalloc_mmap_morecore): Improve to allow mmap
  22         to select a base mapping address if none is otherwise given.
  23         (mmalloc_findbase): New function that user can call to find
  24         an available mapping address of a given size.
