	* tests/tm_basic.cxx (run_all_tests): Changed initial delay from
	100 ticks to 2. This is adequate for the purpose of letting the
	clock get going, while 100 ticks was too long on simulators.

	Use CYGNUM_HAL_STACK_SIZE_TYPICAL for the stack size instead of
	CYGNUM_HAL_MINIMUM_STACK_SIZE.
	Except for stack checking and the idle thread stack which uses 
	CYGNUM_HAL_STACK_SIZE_MINIMUM.

	* tests/kcache1.c:
	* tests/kcache2.c:
	Made all CYG_INTERRUPT_STATE variables register variables. The
	value of this variable has to survive cache invalidation and does
	not in some testing permutations that are unoptimized.
	Fixes PR 19165.

	* include/kapi.h: Type of cyg_tick_count_t changed to cyg_uint64.
	Response to PR 19320.

1999-03-19  Gary Thomas  <[e-mail]>

	* tests/tm_basic.cxx: Much better analysis of clock interrupt times.
	Print average deviation instead of variance.  Also print "confidence"
	numbers which are a measure of "how likely" a particular number would
	be relative to the mean and min of the sample set.

1999-03-17  Gary Thomas  <[e-mail]>

	* tests/tm_basic.cxx: Improve messages and layout.
	Better message for 'hardware clock tick' value.

	* src/common/clock.cxx: Be more careful about clock latency delta
	values that are used/kept - some hardware can yield incorrect values.

	* tests/testaux.hxx: Use HAL recommended stack size for default.

1999-03-16  Nick Garnett  <[e-mail]>

	* src/common/thread.cxx:
	Removed MIPS specific definition of idle_thread_stack[]. This is
	so it gets the benefit of the redefinition of
	CYGNUM_KERNEL_THREADS_IDLE_STACK_SIZE. This definition has also
	been made static, since the MIPS compiler would otherwise put it
	in the .data section.

	* include/intr.hxx (class Cyg_Interrupt):
	Changed implementation of Cyg_Interrupt::interrupts_enabled() to
	test the value of disable_counter, rather than the hardware.

1999-03-15  Nick Garnett  <[e-mail]>

	* tests/kcache1.c:
	* tests/kcache2.c: 
	Added interrupt disables around cache operations. If these take
	too long, an inopportune interrupt can disrupt the cache contents,
	or result in the interrupt seeing an inconsistent world.

1999-03-15  Gary Thomas  <[e-mail]>

	* src/debug/dbg-thread-demux.c: 
	Only try handling the SPARClite-SLEB vector correctly if
	CYG_HAL_USE_ROM_MONITOR_CYGMON ie. we are talking with CygMon.
	Otherwise the code is wrong, but also not used.  No matter.

	* src/debug/dbg-thread-demux.c (patch_dbg_syscalls): 
	Use the correct vector table slot for SPARClite-SLEB; it's not 15
	on here, it's BSP_VEC_MT_DEBUG from the hal's hal_cygm.h

1999-03-11  Nick Garnett  <[e-mail]>

	* tests/testaux.hxx:
	Move definition of inline placement operator new outside of ifdef
	for NTHREADS so that it can be used by other code.

	* tests/intr0.cxx:
	* tests/thread1.cxx:
	Make use of placement operator new rather than dynamic one in
	intr0. Removed duplicate definition from thread1.
