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

Thu Sep 24 18:14:19 1998  Jesper Skov  <jskov@cygnus.co.uk>

	* include/hal_intr.h: Read the interrupt control registers back
	after writing to them to ensure that the value is not sitting in
	the store buffer.
	Also put _ around variable names in HAL_INTERRUPT_CONFIGURE for
	consistency.
	
1998-09-24  Nick Garnett  <nickg@cygnus.co.uk>

	* include/hal_intr.h:
	Inverted mask for level in HAL_INTERRUPT_SET_LEVEL().

	* src/vectors.S:
	Added correct implementations of decode_interrupt macro for
	chained interrupt processing.
	Modified call to cyg_instrument() to pass table offset as well as
	vector number.
	Include <pkgconf/kernel.h> to allow call to cyg_instrument() to be
	enabled.

1998-09-14  Bart Veer  <bartv@cygnus.co.uk>

	* 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.

	* include/hal_intr.h: 
	* src/vectors.S: 
	Replaced CYGIMP_KERNEL_INTERRUPTS_CHAIN with new
	CYGIMP_HAL_COMMON_INTERRUPTS_CHAIN.

1998-09-12  Bart Veer  <bartv@cygnus.co.uk>

	* include/pkgconf/hal_mn10300.h:
	Added missing descriptions (PR 17184)

	* src/hal_misc.c (exception_handler): 
	Sort out exception handling options (PR 16953)

Thu Sep 10 20:24:02 1998  Hugo Tyson  <hmt@cygnus.co.uk>

	* src/vectors.S (__default_interrupt_vsr): 
	Fix a bug.  Wrong offset when restoring the PSW tends to screw
	things up rather.

        PR 17153

	* src/vectors.S (__default_interrupt_vsr): Pass correct vector
	value to isr.

1998-09-09  Nick Garnett  <nickg@cygnus.co.uk>

	* include/hal_arch.h:
	Removed distinction between interrupt and thread switch contexts
	in HAL_SavedRegisters. Modified appropriate macros to reflect this.

	* src/hal_misc.c (cyg_hal_invoke_constructors):
	Added call to patch_dbg_syscalls() for Cygmon hosted builds.

	* src/context.S (_hal_thread_switch_context):
	Adjust thread context so that it has the same structure as the
	state saved by interrupt and exception handlers. This makes
	supporting thread-aware debugging easier.

	* src/vectors.S:
	Moved nmi and trap vectors to correct slots in vsr table.
	Now place arg3 of interrupt_end() in correct stack slot.

1998-09-04  Bart Veer  <bartv@cygnus.co.uk>

	* src/vectors.S (__default_interrupt_vsr):
	Fixed type in configuration option name.

	Changed conditionals on runtime initialisation of VSR table to not
	do it in simulated targets.

1998-09-02  Bart Veer  <bartv@cygnus.co.uk>

	* src/PKGconf.mak: 
	Sort out package naming conventions.

1998-09-02  Nick Garnett  <nickg@cygnus.co.uk>

	* src/vectors.S:
	Moved NMI and TRAP VSRs down 1 word to match cygmon's use of the
	vector table. This may need to change back in the future.

1998-09-01  Nick Garnett  <nickg@cygnus.co.uk>

	* include/hal_intr.h:
	Added CYG_VSR_COUNT, CYG_EXCEPTION_COUNT and CYG_ISR_COUNT.
	Modified HAL_TRANSLATE_VECTOR() for mn103002 to provide slots
	for the NMI vectors at start of hal_interrupt_* tables.

	* src/hal_misc.c (exception_handler):
	Added support for decoding NMI vectors and for calling watchdog
	ISR if present.

	* src/vectors.S:
	Modified behaviour of __default_nmi_vsr to support watchdog timer
	properly.
	Fixed indirection bug in __nmi and __trap.
	Modified offsets in hal_interrupt_* tables to provide slots for
	NMI vectors at start in mn103002.

Fri Aug 28 10:09:03 1998  Jonathan Larmour  <jlarmour@cygnus.co.uk>

	* src/hal_misc.c: 
	rename __main() to cyg_hal_invoke_constructors() and remove
	initialised test

	* src/vectors.S (_start): 
	Change call of __main() to cyg_hal_invoke_constructors(), and call
	of main() to cyg_start()

1998-08-25  Nick Garnett  <nickg@cygnus.co.uk>

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

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

1998-08-21  Nick Garnett  <nickg@cygnus.co.uk>

	* include/hal_cache.h: 
	Now includes cyg_type.h rather than ktypes.h.
	
	* src/hal_misc.c:
	Added calls to turn the caches on. But disabled them
	since they interact poorly with Cygmon (Cygmon does not
	flush the caches when setting/clearing breakpoints).

Wed Aug 19 18:19:32 1998  Jonathan Larmour  <jlarmour@cygnus.co.uk>

	Reorgnized ifdefs to better support kernel porting.
