1999-04-23  Hugo Tyson  <[e-mail]>

	* tests/testcx7.cxx: T2_MALLOC definition; only make it smaller
	than the main consumer malloc if coaleasing is enabled, otherwise
	the mempool cannot allocate blocks for the consumer for next time.
	Fixes PR 18817 - only a random perm disable coalescence.

	* tests/test7.c: Ditto.

1999-04-15  John Dallaway  <[e-mail]>

	* include/pkgconf/uitron.h: Tidy display string capitalization.

1999-04-09  Hugo Tyson  <[e-mail]>

	* include/uit_func.inl (dis_dsp): Remove bad old code which used
	to lock the scheduler to implement dis_dsp() and ena_dsp() - which
	also stopped the clock, for example.  Instead change the calling
	thread's priority to 0 internally so that it cannot be preempted
	by uITRON threads at least, whose priorities are 1--N.  Same
	applies to loc/unl_cpu().  Save the "real" priority in a static,
	and take notice of it everywhere relevant, such as thread and
	system state inquiries, changing (our own) priority, checking for
	dispatch enabled in sleeping calls, and so on.

	* src/uit_func.cxx: New variable cyg_uitron_dis_dsp_old_priority
	for holding the "real" priority of a thread whilst we change our
	priority to zero (the highest) to prevent dispatching in dis_dsp()
	or loc_cpu().

	* include/uit_func.inl (get_tid): Return 0 for the task id if not
	in a uITRON thread, this is better conformance to the spec.

1999-03-22  Hugo Tyson  <[e-mail]>

	* src/uit_objs.cxx: 
	Use CYGNUM_HAL_STACK_SIZE_TYPICAL for the stack size instead of
	CYGNUM_HAL_MINIMUM_STACK_SIZE.

	Change all non-applicable cases to use CYG_TEST_NA rather than
	CYG_TEST_PASS/CYG_TEST_EXIT

1999-02-22  Hugo Tyson  <[e-mail]>

	* src/uit_objs.cxx: Eeeek!  Previous fix was bogus: the override
	was too late in the file to take effect.  The declaration of the
	objects (including stacks) is moved to below the override CPP
	runes.

1999-02-12  Hugo Tyson  <[e-mail]>

	* src/uit_objs.cxx (CYG_UITRON_DECL):
	Override CYGNUM_UITRON_STACK_SIZE if CYGNUM_HAL_MINIMUM_STACK_SIZE
	demands it.

	* include/pkgconf/uitron.h (CYGNUM_UITRON_STACK_SIZE): 
	Document that this option can be overridden by HALs demands.

	* src/uit_func.cxx (SET_UP_PTRS): 
	PR 17999; work around codegen bug on tx39 with -Os.
	The code is better with the fix regardless, so it's got no
	downside.  Explicitly condition whether to run a follow-on loop
	rather than letting the for-loop sort it out itself.

1998-11-16  Hugo Tyson  <[e-mail]>

	* tests/testcx7.cxx (check_waitstate): 
	Add a routine to check the reported waiting state of the synch
	object in question, and call it as necessary.  This only added to
	the C++ version of the test for enhanced coverage, in case the
	enquiry call perturbs the object state; having both versions
	present is better.  This checks a very recent fix to
	kernel...thread.cxx (1998-10-27).

1998-10-21  Hugo Tyson  <[e-mail]>

	* src/uit_func.cxx: 
	Provide weakly named dummies for task[1-4], which are the defaults
	referred to by the task array, so that the uITRON system can be
	initialized even when no uITRON tasks have been provided (so long
	as no other changes to the task init configury have been made)
	This does not pollute the namespace, for these are weak symbols.
	Changing them to cyg_uitron_task... would be possible, but it
	carries the false implication that those are cygnus names, when
	they are really entirely up to the user.

	* tests/test[123456789].c: 
	* tests/testcxx.cxx: 
	* tests/testcx[23456789].cxx: 
	Undo the previous change: remove dummies for task[1-4] when we
	decide not to test anything, they will be provided with weak names
	regardles in src/uit_func.cxx.

1998-10-16  Hugo Tyson  <[e-mail]>

	* tests/testcx*.cxx (cyg_start): 
	[all the C++ tests]
	changed cyg_start to externC so that it truly does override the
	default one; this is needed for handling the "I cannot test in
	this configuration" failures.  Of course the C ones were C to
	start with.

	* tests/testcx[23456789].cxx: 
	All tests are now much more self-configuring wrt turning off
	if there are no uITRON objects of the right type to manipulate.
	The huge (50-line) #if statement is arranged the way it is so that
	clauses checking on each feature can be pasted in and out easily.
	So yes, the "&& 1" at the end has a purpose.
	
	Here for the record is a table of feature versus test-used-in:
	tsk  :: 1 2 3 4 5 6 7 8 9
	sem  ::   2 3   5 6 7 8

	* tests/test9.c: 
	* tests/testcx9.cxx: 
	New tests, test create and delete of memory pools

1998-10-15  Hugo Tyson  <[e-mail]>

	* include/pkgconf/uitron.h: 
	Add configury for create/delete of memory pools.
	Tidy up naming of initializer macros to use for non-existent
	(initially) uITRON objects.
	Improve comments in CDL-- info fields.
	
	* include/uit_func.h: 
	Add prototypes for cre/del_mpf/mpl().

	* include/uit_func.inl: 
	Implement cre/del_mpf/mpl().

	* src/uit_objs.cxx: 
	Support CYG_UIT_MEMPOOLFIXED_NOEXS/CYG_UIT_MEMPOOLVAR_NOEXS(...)
	mempool construction macros for non-existent (initially) mempools.
	Rename _NONE construction macros to _NOEXS which will make a lot
	more sense to uITRON folks.

1998-10-14  Hugo Tyson  <[e-mail]>

	* include/pkgconf/uitron.h: 
	Add configury for create/delete of tasks.
	
	* include/uit_func.h: 
	Add prototypes for cre/del_tsk(); correct comment in exd_tsk().
	
	* include/uit_func.inl: 
	Implement cre/del_tsk() and complete exd_tsk().
	Improve NULL/NADR checking on other cre/del calls.

	* src/uit_func.cxx (cyg_uitron_start): 
	Deal better with start tasks stuff, for task create/delete.

	* src/uit_objs.cxx: 
	Support CYG_UIT_TASK_NONE(...) task constructor for those tasks
	which do not initially exist

	* tests/PKGconf.mak:
	Add new tests test8.c, testcx[678].cxx to the build.

	* tests/test6.c:
	Tidy comments, untabify.
	
	* tests/test7.c:
	Tidy comments, untabify, test creation with NADR record pointer.
	No impact from the new cre/del_tsk() functionality on test7, since
	a task may only be deleted when it is dormant, so deletion is NOT
	another way out of a waiting state.
	
	* tests/test8.c:
	New test, tests cre_tsk() and del_tsk() and exd_tsk() ie. the
	creation and deletion of tasks.

	* tests/testcx6.cxx:
	* tests/testcx7.cxx:
	* tests/testcx8.cxx:
	New tests, C++ versions of tests 6, 7, and 8.

1998-10-09  Hugo Tyson  <[e-mail]>

	* tests/test7.c: 
	Test interactions with deleting objects (as applicable) and
	killing, signalling and the like.  Also test killing the task
	after other treatments more generically.

	* tests/test6.c (task1): 
	Change "N/A:" to "N/A" in the exit message when we didn't actually
	do any testing due to create/delete being disabled for all object
	types.

1998-10-08  Hugo Tyson  <[e-mail]>

	In general, these changes are to support create/delete of uITRON
	objects; this requires that an object can be destroyed whilst
	there are threads waiting on it, and that they shall be awoken
	with a specific return code E_DLT.  The implementation uses an
	array of pointers in addition to the array of objects: ptrs[N]
	should either be NULL or &objs[N] in this version.  That
	restriction is not checked, in order that in future, true dynamic
	allocation can be used, and ptrs[N] could point anywhere.  The
	implications of this are mainly in the area of getting the
	addresses of objects, via the ptr array or from the object array?
	The config of whether there is a ptr array is per object type.

	* include/pkgconf/uitron.h: 
	Configury of the existence or not of create/delete for object
	type: initially only SEMAS, MBOXES, FLAGS.
	Configury of the number of objects created initially, if cre/del
	are enabled.

	* tests/test6.c:
	* tests/test7.c:
	* tests/PKGconf.mak:
	Two new test programs (duh!): test6 tests create and delete of
	SEMAS, MBOXES, FLAGS explicitly, for bad params handling, ability
	to use after deletion and recreation &c &c.  test7 tests the
	semantics of sleeping on some synchronization primitive, permed
	with suspension, signalling, killing, releasing and so forth.
	Both will migrate into C++ versions also in future.

	* include/uit_func.h:
	Enable cre/del_{mbx,flg,sem} prototypes.
