4062001-04-26 Alexandre Oliva <aoliva@redhat.com>

408 * configure.in: Obtain THREADS with `gcc -v'.
409 * configure: Rebuilt.
410
4112001-04-05 Hans Boehm <hans_boehm@hp.com>
412
413 * misc.c: Back out buggy changes to stack clearing code.
414 Reduce CLEAR_SIZE to 1/4 of original value to reduce time
415 spent clearing memory.
416
4172001-04-04 Hans Boehm <hans_boehm@hp.com>
418
419 * finalize.c:
420 - Accomodate finalization requests for static objects.
421 (Will be required by hash synchronization. May be needed
422 in some configurations now.)
423
424 * gc_priv.h:
425 - Define MIN_WORDS. All allocation requests are rounded
426 up to at least this size. Removes a subtle assumption that
427 Java objects have a 2 word header.
428
429 * gcconfig.h:
430 - Adjust Linux/IA64 configuration for non-ancient kernels.
431 (Necessary fix for IA64.)
432
433 * linux_threads.c:
434 - Fix syntax error in currently unused code. Will be needed
435 for Linux/PA-RISC.
436
437 * malloc.c:
438 - Handle MIN_WORDS.
439
440 * misc.c:
441 - Handle MIN_WORDS.
442 - Change stack cleaning code to typically clear about one tenth
443 the memory it used to in the threads configuration. Occasionally
444 still clear more. (This is really a fix for a long-standing
445 and fairly significant performance bug with threads.)
446
447 * os_dep.c:
448 - Fix the code for finding the beginning of the data segment under
449 Linux. I believe this is necessary for some IA64 Linux
450 distributions. It will also helo other platforms, though those
451 may additionally require a gcconfig.h adjustment. (This basically
452 works around the absence of a data_start or __data_start
453 definition in glibc.)
454
455 * test.c:
456 - Handle rounding due to MIN_WORDS.
457
4582001-03-22 Tom Tromey <tromey@redhat.com>
459
460 * Makefile.am (gctest_LDFLAGS): Use -shared-libgcc.

4622001-03-19 Tom Tromey <tromey@redhat.com>
463
464 * Makefile.in: Rebuilt.

466
4672001-03-16 Tom Tromey <tromey@redhat.com>
468
469 * Makefile.in: Rebuilt.
470 * Makefile.am (TESTS_ENVIRONMENT): New macro.
471
4722001-01-23 Rod Stewart <stewart@lab43.org>
473
474 * gcconfig.h: Check for `__arm__', not `arm'.
475
4762000-12-30 Bryce McKinlay <bryce@albatross.co.nz>
477
478 * configure.in: Rename THREADLIB to THREADLIBS.
479 * Makefile.am (LINK): Add $(THREADLIBS) to libtool command line. This
480 ensures that we link the correct version of the linuxthreads semaphore
481 functions.
482 * Makefile.in: Rebuilt.
483 * configure: Rebuilt.
484
485 * linux_thread.c (GC_thr_init, GC_suspend_handler): Add SIGABRT to the
486 list of signals which are not blocked during suspend in the NO_SIGNALS
487 case.
488
4892000-12-23 Hans Boehm <Hans_Boehm@hp.com>
490
491 * gcj_mlc.c (GC_gcj_malloc): Don't release allocation lock twice.
492
4932000-12-15 Bryce McKinlay <bryce@albatross.co.nz>
494
495 * Makefile.dist: Renamed from Makefile.orig.
