+ 	* tests/stress_threads.c: Don't print text from alarm handler.
+
+1999-04-27  Gary Thomas  <gthomas@cygnus.co.uk>
+
+	* tests/tm_basic.cxx: 
+	Use/test 'cyg_thread_delete()' function.
+	Add ability to compute statistics with first datum removed which
+	can show up cache effects.
+	Show thread stack usage.
+
+1999-04-26  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	* include/kapi.h: Add missing function cyg_thread_delete();
+	otherwise there is no way in the C API to re-use thread memory
+	safely.  It just calls the destructor of the Cyg_Thread class.
+
+	* src/common/kapi.cxx (cyg_thread_delete): Implement it.
+
+1999-04-26  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	* tests/stress_threads.c: Commit a better version for Mark since I
+	happen to have it here; having addressed the main concern of my
+	approval process.  It runs better in sims so long as the
+	constructor execution isn't messed with, nor timeslicing nor
+	priority inheritance.
+
+1999-04-23  Mark Galassi  <rosalia@cygnus.com>
+
+	* tests/stress_threads.c (setup_death_alarm): shortened the
+	simulator time by another factor of 10, hoping that it will not
+	slow down nightly testing for simulator platforms too much.
+	(perform_stressful_tasks): added writing of a bit pattern to the
+	malloc()-ed spaces.  Also reduced stack requirements for threads.
+
+1999-04-23  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	* src/common/timer.cxx (Cyg_Timer::activate): we must also disable
+	the alarm when resetting it so as to remove it from its queue, so
+	that the enable afterwards places it on the right queue instead of
+	assuming that, being enabled, it's already there.  (if not
+	enabling, the behaviour is unchanged and correct) This was
+	detected by uITRON tests[cx]4, with some random perms including
+	enable CYGIMP_KERNEL_COUNTERS_MULTI_LIST,
+	value CYGNUM_KERNEL_COUNTERS_MULTI_LIST_SIZE {8}.
+	The PR is 19475.
+
+1999-04-21  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	* tests/bin_sem1.cxx (bin_sem1_main): Doh!  Use priorities 4 and 5
+	for the two threads so that they are unique (with a bitmap
+	scheduler, the threads had prios 0 and 1 resp, which causes an
+	assert in the attempt to set thread 0's prio to 1, "prios not
+	unique").  PR 19904.
+
+1999-04-20  Hugo Tyson  <hmt@cygnus.co.uk>

+1999-04-20  Jonathan Larmour  <jlarmour@cygnus.co.uk>
+
+	* tests/kcache2.c: 
+	Reduce iterations for time_ilock(), time_dlock(), and test_dzero()
+	if a simulated environment is detected
+	Fix for PR 19853
+
+1999-04-19  Jonathan Larmour  <jlarmour@cygnus.co.uk>
+
+	* tests/kill.cxx: Make delay ticks greater than 1 to prevent
+	scheduling problems if the clock rolls over immediately
+	Fix for PR 19516
+
+1999-04-19  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	* tests/bin_sem1.cxx (bin_sem1_main): Add priorities to the
+	threads so that they run sequentially like the tester expected.
+	Otherwise simple timing, and shorter timeslicing, causes failure
+	to be reported; likewise if the kernel happens not to run entry0
+	first!
+        (another checkin)
+	(bin_sem1_main): Add conditional use of set_priority on
+	CYGIMP_THREAD_PRIORITY as it should be.
+
+1999-04-14  Jesper Skov  <jskov@cygnus.co.uk>
+
+	* src/debug/dbg_gdb.cxx: Fixed compiler warnings, cleaned up stub

+
+1999-04-14  Mark Galassi  <rosalia@cygnus.com>
+
+	* tests/PKGconf.mak: added an ifndef for the AEB-1 board so that
+	stress_threads is only built conditionally.
+
+	* tests/stress_threads.c: added more config smarts suggested by
+	Jesper for his configurations.
+
+1999-04-13  Jesper Skov  <jskov@cygnus.co.uk>

+
+1999-04-13  Mark Galassi  <rosalia@cygnus.com>
+
+	* tests/stress_threads.c: simple stressing of thread
+	creation/deletion with some memory-intensive and alarm-based
+	tasks.  This version is set so that it dies after DEATH_TIME_LIMIT
+	seconds, currently set to 120.  #undef-ing DEATH_TIME_LIMIT makes
+	the test run forever.  This is currently not working with the
+	bitmap scheduler, probably for some simple reason, but I have not
+	yet broken it down to see why.

+1999-04-09  Hugo Tyson  <hmt@cygnus.co.uk>
+
+	Generally: thread->to_queue_head() moves a thread to the head of
+	whatever queue it is on, if relevant.  This is so that a thread

+	be undesirable.  Particularly for internal use of priorities in
+	the uITRON compatibility layer.
