	terms of this.

2000-10-09  Gary Thomas  <gthomas@redhat.com>

	* src/vectors.S (start): Need to handle ^C for all applications.

2000-09-13  Jonathan Larmour  <jlarmour@redhat.com>

	* src/vectors.S: When calling C functions, ensure there is 16 bytes
	space for the parameter flushback area (as per the calling convention)
	on the stack

2000-09-07  Jonathan Larmour  <jlarmour@redhat.com>

	* include/basetype.h: Don't need special alignment after all - it was
	a bug elsewhere.

2000-09-06  Gary Thomas  <gthomas@redhat.com>

	* include/basetype.h: Need special alignment to match the way
	the compiler/linker actually do things.

	* cdl/hal_v85x.cdl: Improve variant handling and specification.

2000-08-30  Gary Thomas  <gthomas@redhat.com>

	* src/vectors.S (start): Allow programs to field NMI exceptions.

2000-07-24  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* include/basetype.h: Removed definition of CYG_LABEL_NAME().

	* src/v85x.ld: 	Switched to new table definition mechanism.

2000-07-21  Gary Thomas  <gthomas@redhat.com>

	* src/vectors.S (_hal_plf_reset_board): Needs to be defined in all
	configurations.

2000-06-27  Jesper Skov  <jskov@redhat.com>

	* src/vectors.S:
	* src/hal_mk_defs.c: 
	Fix compiler warnings.

	* src/hal_misc.c (hal_default_isr): Let common version do the
	checks.

2000-06-15  Gary Thomas  <gthomas@redhat.com>

	* src/hal_mk_defs.c: 
	* src/vectors.S: 
	* src/hal_misc.c (hal_default_isr): Update for new debug
	vector support.

	* include/hal_intr.h: 
	* src/vectors.S (do_interrupt): Proper handling of chained
	interrupts.

2000-06-12  Gary Thomas  <gthomas@redhat.com>

	* src/vectors.S (return_from_exception_or_interrupt): Revert 
	reorg change (05-26) which broke GDB breakpoints.

2000-06-08  Jesper Skov  <jskov@redhat.com>

	* include/hal_arch.h (CYGARC_HAL_SAVE_GP, CYGARC_HAL_RESTORE_GP):
	Added.

2000-05-26  Gary Thomas  <gthomas@redhat.com>

	* src/vectors.S: Slight reorg of trap vectors (more readable).

2000-05-25  John Dallaway  <jld@redhat.com>

	* cdl/hal_v85x.cdl: Tidy display strings.

2000-05-25  Gary Thomas  <gthomas@redhat.com>

	* src/vectors.S: Handle different chips (number of interrupt
	sources differs, exception table is altered, etc).

	* include/hal_intr.h: Actual interrupt layout now defined by
	variant/platform since these differ depending on the chip.

2000-05-03  Gary Thomas  <gthomas@redhat.com>

	* include/hal_arch.h: New breakpoint instruction ("br *").

2000-04-14  Gary Thomas  <gthomas@redhat.com>

	* src/hal_misc.c (exception_handler): Proper handling of nested
	[watchdog] interrupts - don't corrupt GDB registers.

	* src/hal_mk_defs.c: Add some symbols required for NMI handling.

	* src/vectors.S (return_from_exception_or_interrupt): 
	Properly handle different cases for exception, NMI and ISR.

	* include/hal_intr.h (HAL_TRANSLATE_VECTOR): Ignore interrupt
	chaining - doesn't happen on this hardware.

2000-04-11  Gary Thomas  <gthomas@redhat.com>

	* src/vectors.S (exception): Handle NMI.  In particular, need to
	have appropriate bits set so they clear and also get the state
	from the proper save registers.
	(exception): Register save was wrong - ROM only.

2000-03-31  Gary Thomas  <gthomas@redhat.com>

	* src/hal_mk_defs.c: Add definition for 'ep' register.

	* include/hal_intr.h: 
	* cdl/hal_nec.cdl: Add config option to choose between inline and
	real functions for interrupt macros.

	* src/vectors.S: Tune up - use SLD/SST for smaller, faster code
	in context load/save routines.  Also remove IRQ trace/debug code.

2000-03-30  Gary Thomas  <gthomas@redhat.com>

	* src/vectors.S (do_interrupt): Can't use R13 across function calls.
	This caused instability when turning on kernel instrumentation.

	* include/hal_intr.h: Use out-of-line code for interrupt functions
	for tracing/testing.

	* src/vectors.S: Working support for separate interrupt stack.
	Some debug/trace code left in.

	* src/hal_mk_defs.c: 
	* include/hal_arch.h: Documented API does not match actual GCC 
	register usage. Need to save R1/R2/R4/R5 for setjmp/longjmp.

2000-03-27  Gary Thomas  <gthomas@redhat.com>

	* src/vectors.S (do_interrupt): Pass regs to ISR & DSR.

	* include/basetype.h: Endian-ness was incorrect.

	* include/hal_arch.h: 
	* src/hal_mk_defs.c: Complete setjmp/longjmp support.

	* src/vectors.S: Add interrupt stack.

2000-03-21  Gary Thomas  <gthomas@redhat.com>

	* src/vectors.S (_hal_plf_reset_board): Add board reset function.

	* include/hal_arch.h (CYGHWR_TEST_PROGRAM_EXIT): Define RESET for ROM
	based programs.
