2004-04-22  Jani Monoses <[e-mail]>

	 * cdl/hal_mn10300.cdl :
	 Invoke tail with stricter syntax that works in latest coreutils. 

2003-12-08  Gary Thomas  <[e-mail]>

	* src/hal_misc.c: Only declare __mem_fault_handler if GDB stubs
	are included (and it will be used).

2003-01-31  Mark Salter  <[e-mail]>

	* src/hal_syscall.c (hal_syscall_handler): Let generic syscall code
	handle exit.

2002-12-06  Mark Salter  <[e-mail]>

	* cdl/hal_mn10300.cdl: Add CYGINT_HAL_MN10300_MEM_REAL_REGION_TOP.
	* include/hal_intr.h: Support CYGINT_HAL_MN10300_MEM_REAL_REGION_TOP.

2002-04-29  Jonathan Larmour  <[e-mail]>

	* src/vectors.S:
	Don't use .file as it can confuse debugging since the .file
	doesn't contain the path and therefore the debugger will never
	know where it lives! This conflicts with using -Wa,--gstabs.

2002-04-15  Jonathan Larmour  <[e-mail]>

	* src/hal_syscall.c (hal_syscall_handler): Add extra sig argument to
	__do_syscall.

2001-11-16  Nick Garnett  <[e-mail]>

	* src/hal_misc.c (hal_msbit_index): Fixed this function so that it
	actually works!

2001-10-16  David Howells  <[e-mail]>

	* src/hal_syscall.c: mustn't increment the return address by 4.
	* cdl/hal_mn10300.cdl: moved the RTC configuration previously
	added to the ASB2305 platform.

2001-10-16  David Howells  <[e-mail]>

	* src/vectors.S: conditionally call diagnostic macros on entry and
	exit to default NMI handler and make inclusion of RedBoot header
	file conditional.

2001-10-15  David Howells  <[e-mail]>

	* include/mn10300_stub.h: added syscall handling.
	* src/hal_syscall.c: ditto
	* src/mn10300_stub.c: ditto
	* src/vectors.S: ditto
	* cdl/hal_mn10300.cdl: added RTC configuration.

	with AM33v2 exceptions.

2001-01-18  Nick Garnett  <[e-mail]>

	* src/vectors.S: Added underscore to reference to
	cyg_scheduler_sched_lock, since CYGBLD_ATTRIB_ASM_ALIAS() now adds
	one automatically.

2000-11-30  Drew Moseley  <[e-mail]>

	* include/hal_arch.h: Handle Cygmon interrupt stack.  ie For
	Cygmon we must switch to a new stack immediately on exception to
	make sure that we don't modify the application stack at all since
	GDB may be using it.
	* src/vectors.S: Ditto.

2000-10-20  Jesper Skov  <[e-mail]>

	* src/hal_misc.c: Update __mem_fault_handler declaration.

2000-08-15  Drew Moseley  <[e-mail]>

	* src/mn10300_stub.c (__is_breakpoint_function): Prepend an _ to
	breakinst.  Apparently the symbol generation has changed requiring
	this.

2000-08-14  Drew Moseley  <[e-mail]>
