+2002-04-15  Jonathan Larmour  <jlarmour@redhat.com>
+
+	* src/hal_syscall.c (hal_syscall_handler): Add extra sig argument to
+	__do_syscall.
+
+2001-12-10  Richard Sandiford  <rsandifo@redhat.com>
+
+	* src/vectors.S (save_state): Remove unnecessary DDR diddling when
+	handling breaks.  Use BPCSR rather than BPCSR-4 as the break address.
+	(restore_state): Take two new arguments: the register that the
+	PC should be loaded into, and the argument to the rett instruction.
+	(_break): If handling a break instruction, return to the following
+	instruction using a normal "ret".  Ignore other kinds of break if
+	they were triggered when traps were disabled; assume that an
+	interrupt or exception handler has triggered a stack watchpoint
+	accidentally.  Correct GP calculation.  Return using "rett #1"
+	rather than "rett #0".
+
+2001-11-28  Hugo Tyson  <hmt@redhat.com>
+
+	* src/vectors.S (_vectors): if defined(CYGPKG_HAL_FRV_FRV400) &&
+	defined(CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS), add macro break_VSR
+	to create a VSR entry which leaps to _break; rearrange the
+	initialization of the VSR table so that the counts are correct;
+	use break_VSR in slot 255; define _break which calls break_handler()
+	much akin to exception handler().	
+
+	Note that there is no need to define CYGSEM_HAL_FRV_HW_DEBUG for
+	the FRV_FRV400 target; while we do use Hardware Debug, we don't
+	use *that* sort of hardware debug, specifically we do not use
+	hardware single-step, because it breaks as soon as we exit debug
+	mode, ie whilst we are still within the stub.  But vectors.S does
+	the same tidy-up of machine state, conditioned on FVR400 instead.
+
+2001-10-17  Gary Thomas  <gthomas@redhat.com>
+
+	* src/frv_stub.c: Slight cleanup - only need |VLIW|+1 possible
+	breakpoint locations.
+
+2001-10-16  Gary Thomas  <gthomas@redhat.com>
+
+	* src/vectors.S (_exception_return): Remove *bad* workaround code
+	now that single step VLIW works properly.
+
+	* src/frv_stub.c (__clear_single_step): 
+	(__single_step): Restructure to support VLIW sequences.
+
+2001-10-15  Gary Thomas  <gthomas@redhat.com>
+
+	* include/hal_arch.h: Remove [bogus] CYG_HAL_TABLE macros since 
+	the common ones work fine on this architecture.
+
+	* src/vectors.S: 
+	* src/frv_stub.c: 
+	* cdl/hal_frv.cdl: Add CDL to describe various [hardware] debug
+	options.
+
+2001-10-01  Gary Thomas  <gthomas@redhat.com>
+
+	* src/vectors.S: [FRV400] can't return from exception to a packed
+	instruction - this yields illegal instruction.
+	
+2001-10-11  Gary Thomas  <gthomas@redhat.com>
+
+	* cdl/hal_frv.cdl: 
+	* include/basetype.h: 
+	* include/hal_arch.h: 
+	* include/hal_intr.h: 
+	* include/frv_stub.h:

+	* src/context.S: 
+	* src/hal_syscall.c: New port for FRV architecture.
