 295             with final tuning by Bryce McKinlay

 300 2001-05-01  Jeffrey Oldham  <oldham@codesourcery.com>
 301
 302         * gc_priv.h (UNLOCK): Change type of GC_noop1 argument.
 303         (GC_noop1): Change declaration to take one argument.
 304
 305 2001-04-26  Alexandre Oliva  <aoliva@redhat.com>
 306
 307         * configure.in: Obtain THREADS with `gcc -v'.
 308         * configure: Rebuilt.
 309
 310 2001-04-05  Hans Boehm  <hans_boehm@hp.com>
 311
 312         * misc.c: Back out buggy changes to stack clearing code.
 313         Reduce CLEAR_SIZE to 1/4 of original value to reduce time
 314         spent clearing memory.
 315
 316 2001-04-04  Hans Boehm  <hans_boehm@hp.com>
 317
 318         * finalize.c:
 319         - Accomodate finalization requests for static objects.
 320           (Will be required by hash synchronization.  May be needed
 321           in some configurations now.)
 322
 323         * gc_priv.h:
 324         - Define MIN_WORDS.  All allocation requests are rounded
 325           up to at least this size.  Removes a subtle assumption that
 326           Java objects have a 2 word header.
 327
 328         * gcconfig.h:
 329         - Adjust Linux/IA64 configuration for non-ancient kernels.
 330           (Necessary fix for IA64.)
 331
 332         * linux_threads.c:
 333         - Fix syntax error in currently unused code.  Will be needed
 334           for Linux/PA-RISC.
 335
 336         * malloc.c:
 337         - Handle MIN_WORDS.
 338
 339         * misc.c:
 340         - Handle MIN_WORDS.
 341         - Change stack cleaning code to typically clear about one tenth
 342           the memory it used to in the threads configuration.  Occasionally
 343           still clear more.  (This is really a fix for a long-standing
 344           and fairly significant performance bug with threads.)
 345
 346         * os_dep.c:
 347         - Fix the code for finding the beginning of the data segment under
 348           Linux.  I believe this is necessary for some IA64 Linux
 349           distributions.  It will also helo other platforms, though those
 350           may additionally require a gcconfig.h adjustment.  (This basically
 351           works around the absence of a data_start or __data_start
 352           definition in glibc.)
 353
 354         * test.c:
 355         - Handle rounding due to MIN_WORDS.

 362
 363         * Makefile.in: Rebuilt.
