   5         and the start of the BSS on FreeBSD/i386.
   6
   7 2002-03-30  Krister Walfridsson  <cato@df.lth.se>
   8
   9         * include/private/gcconfig.h: define DYNAMIC_LOADING for ELF

 316 2001-04-05  Hans Boehm  <hans_boehm@hp.com>
 317
 318         * misc.c: Back out buggy changes to stack clearing code.
 319         Reduce CLEAR_SIZE to 1/4 of original value to reduce time
 320         spent clearing memory.
 321
 322 2001-04-04  Hans Boehm  <hans_boehm@hp.com>
 323
 324         * finalize.c:
 325         - Accomodate finalization requests for static objects.
 326           (Will be required by hash synchronization.  May be needed
 327           in some configurations now.)
 328
 329         * gc_priv.h:
 330         - Define MIN_WORDS.  All allocation requests are rounded
 331           up to at least this size.  Removes a subtle assumption that
 332           Java objects have a 2 word header.
 333
 334         * gcconfig.h:
 335         - Adjust Linux/IA64 configuration for non-ancient kernels.
 336           (Necessary fix for IA64.)
 337
 338         * linux_threads.c:
 339         - Fix syntax error in currently unused code.  Will be needed
 340           for Linux/PA-RISC.
 341
 342         * malloc.c:
 343         - Handle MIN_WORDS.
 344
 345         * misc.c:
 346         - Handle MIN_WORDS.
 347         - Change stack cleaning code to typically clear about one tenth
 348           the memory it used to in the threads configuration.  Occasionally
 349           still clear more.  (This is really a fix for a long-standing
 350           and fairly significant performance bug with threads.)
 351
 352         * os_dep.c:
 353         - Fix the code for finding the beginning of the data segment under
 354           Linux.  I believe this is necessary for some IA64 Linux
 355           distributions.  It will also helo other platforms, though those
 356           may additionally require a gcconfig.h adjustment.  (This basically
 357           works around the absence of a data_start or __data_start
 358           definition in glibc.)
 359
 360         * test.c:
 361         - Handle rounding due to MIN_WORDS.

 368
 369         * Makefile.in: Rebuilt.
