mmalloc/ChangeLog

   1 Wed Jul 10 23:53:42 1996  Fred Fish  <fnf@cygnus.com>
   2
   3         * detach.c (mmalloc_detach): Fix bug in computation of negative
   4         brk value.
   5         * mmcheck.c (mmcheckf): Renamed from mmcheck and new FORCE argument
   6         added.  Replaced hack that always allowed checking routines to be
   7         installed and enforce restriction that they have to be installed
   8         prior to allocating any memory on the used heap or the FORCE argument
   9         has to be non-NULL.
  10         (mmcheck): New function that calls mmcheckf with FORCE set to zero,
  11         for backwards compatibility.
  12         * mmalloc.c (malloc): Store result in local variable before
  13         returning it.  Makes debugging much easier at negligible cost.
  14         * mmalloc.h (mmcheckf): Declare.
  15         * attach.c (reuse): Call mmcheckf rather than mmcheck.
  16         * mmap-sup.c (__mmalloc_mmap_morecore): Improve to allow mmap
  17         to select a base mapping address if none is otherwise given.
  18         (mmalloc_findbase): New function that user can call to find
  19         an available mapping address of a given size.
