	* include/basetype.h: CYG_DOUBLE_BYTEORDER now in <infra/cyg_type.h>

1999-01-12  Gary Thomas  <[e-mail]>

	* include/basetype.h (CYG_DOUBLE_BYTEORDER): Define ordering
	for words within doubles.

1999-01-12  Nick Garnett  <[e-mail]>

	* include/hal_cache.h: 
	Modified HAL_DCACHE_INVALIDATE_ALL() to correctly touch all cache
	lines twice to ensure that the cache and memory are
	consistent. This is the best we can do without direct support for
	invalidation.
	
	* src/hal_misc.c: Altered call to patch_dbg_syscalls() to pass
	pointer to base of vector rather than a single vector entry.

	compiler error.

1998-10-25  Jesper Skov  <[e-mail]>

	* src/mips-stub.c (__build_t_packet): Replaced
	CYGDBG_KERNEL_DEBUG_GDB_THREAD_SUPPORT with

1998-10-14  Nick Garnett  <[e-mail]>

	* src/context.S (hal_thread_switch_context):

	happy.
	* include/hal_arch.h (HAL_THREAD_INIT_CONTEXT):
	Intialize PC slot in register state.

	* src/hal_misc.c:
	Altered ifdefs to allow building without kernel present.

1998-10-13  Jesper Skov  <[e-mail]>

	* src/hal_misc.c: Use GDB array rather than HAL_SavedRegisters
	structure. Rely on generic stub to pack/unpack the array.

	Initialized R30 to a copy of SP to avoid GDB making bogus memory
	references.

	Added support for Ctrl-C processing when running under Cygmon.
	Fixed a compiler warning.

1998-09-14  Bart Veer  <[e-mail]>

	* src/PKGconf.mak:
	Made vectors.o dependent on the various files that can contain
	makefile variables or rules. This is needed after changes to
	pkgconf.tcl for PRs 17195 and 17286.

Mon Sep 14 11:10:20 1998  Jesper Skov  <[e-mail]>
        PR 17230

	* include/pkgconf/hal_tx39.h:

1998-09-11  Nick Garnett  <[e-mail]>

	number to pass to ISR, even when using chained interrupts.

1998-09-03  Bart Veer  <[e-mail]>

	* src/mips-stub.c:
	Fixed type in config option name.

1998-09-02  Bart Veer  <[e-mail]>

Tue Sep  1 19:26:45 1998  Hugo Tyson  <[e-mail]>

	* src/hal_misc.c: 
	Use CYGDBG_INFRA_DIAG_USE_DEVICE (from infra.h) instead of
	CYG_DIAG_USE_DEVICE (badly named, from kernel.h).

1998-09-01  Nick Garnett  <[e-mail]>

	* include/hal_intr.h:
	Added CYG_EXCEPTION_COUNT.

1998-08-28  Bart Veer  <[e-mail]>

	* src/vectors.S, src/context.S, src/hal_misc.c, src/mips-stub.c:
	Updated for new kernel configuration option symbol names

Fri Aug 28 10:01:24 1998  Jonathan Larmour  <[e-mail]>

	* src/hal_misc.c:
	Rename __main() to cyg_hal_invoke_constructors() to prevent the
	implied link with things called, or related to main(). Remove static
	initialised variable as we can now guarantee it is only called
	once.

	* src/vectors.S:
	Instead of calling main(), call cyg_start() which lives in the infra
	package.
	Explicitly invoke constructors as it isn't done magically for us
	any more, now that main() is no longer used.
	

1998-08-25  Nick Garnett  <[e-mail]>

	* src/vectors.S:
	Now pass pointer to saved registers as third argument to
	interrupt_end().

	* include/hal_arch.h:
	Added macros to support GDB.

Tue Aug 25 02:33:59 1998  Jonathan Larmour  <[e-mail]>

	* include/mips_stub.h, src/hal_misc.c: 
	Add void to prototypes and typedefs that want it to silence warnings

1998-08-21  Nick Garnett  <[e-mail]>

	* include/hal_cache.h:
	Now includes cyg_type.h rather than ktypes.h.

	* src/context.S: 
	* include/hal_arch.h: 
	* include/hal_io.h: 
	* include/hal_intr.h:
	Now uses cyg_type.h rather than ktypes.h.

	* src/hal_misc.c: 
	* src/vectors.S:
	Now uses hal.h rather than kernel.h.

1998-07-23  Nick Garnett  <[e-mail]>

	* include/hal_intr.h: Fixed some issues raised bt code review.

	* src/context.S: 
	* include/hal_arch.h: Fixed some typos raised by code review.

	* include/hal_intr.h (HAL_INTERRUPT_MASK): 
	* src/vectors.S (hal_interrupt_level): Added hal_interrupt_level
	to allow for interaction between HAL_INTERRUPT_UNMASK() and
	HAL_INTERRUPT_SET_LEVEL().
