	* tests/tm_basic.cxx: Ensure that there are enough priorities.

1999-01-25  Nick Garnett  <[e-mail]>

	* tests/kcache2.c (test_dstore): Added call to HAL_DCACHE_SYNC()
	before disabling cache. On some architectures disabling the cache
	would cause the following call to do nothing.
	Fixes PR 18849.

1999-01-22  Jesper Skov  <[e-mail]>

	* tests/tm_basic.cxx: Don't run on Linux target.

1999-01-21  Hugo Tyson  <[e-mail]>
	These changes are to get tests working with the SPARClite port; it
	doesn't do 8-byte register access unless it's properly aligned.
	
	* tests/philo.cxx (cyg_start): 
	Use tests/testaux.hxx to get new threads, to get the alignment
	required; see below.

	* tests/thread2.cxx (thread2_main):
	Use tests/testaux.hxx to get new threads, to get the alignment
	required; see below.

	* tests/tm_basic.cxx: 
	Larger stack for greedy processor.

	* tests/testaux.hxx: 
	thread_obj[][] and stack[][] are now 8-byte aligned like certain
	processors require; Cyg_Thread contains cyg_tick_count which is
	64-bit so any "standalone" C++ object would be so aligned.  These
	dynamically allocated ones should be too.

	Changed API of patch_dbg_syscalls() to take a pointer to the start
	of the vector and insert several vectors.

	* src/debug/dbg_gdb.cxx:
