        * configure: Rebuilt.

2001-04-05  Hans Boehm  <hans_boehm@hp.com>

        * misc.c: Back out buggy changes to stack clearing code.
        Reduce CLEAR_SIZE to 1/4 of original value to reduce time
        spent clearing memory.

2001-04-04  Hans Boehm  <hans_boehm@hp.com>

        * finalize.c:
        - Accomodate finalization requests for static objects.
          (Will be required by hash synchronization.  May be needed
          in some configurations now.)

        * gc_priv.h:
        - Define MIN_WORDS.  All allocation requests are rounded
          up to at least this size.  Removes a subtle assumption that
          Java objects have a 2 word header.

        * gcconfig.h:
        - Adjust Linux/IA64 configuration for non-ancient kernels.
          (Necessary fix for IA64.)

        * linux_threads.c:
        - Fix syntax error in currently unused code.  Will be needed
          for Linux/PA-RISC.

        * malloc.c:
        - Handle MIN_WORDS.

        * misc.c:
        - Handle MIN_WORDS.
        - Change stack cleaning code to typically clear about one tenth
          the memory it used to in the threads configuration.  Occasionally
          still clear more.  (This is really a fix for a long-standing
          and fairly significant performance bug with threads.)

        * os_dep.c:
        - Fix the code for finding the beginning of the data segment under
          Linux.  I believe this is necessary for some IA64 Linux
          distributions.  It will also helo other platforms, though those
          may additionally require a gcconfig.h adjustment.  (This basically
          works around the absence of a data_start or __data_start
          definition in glibc.)

        * test.c:
        - Handle rounding due to MIN_WORDS.
