	* src/generic-stub.c: Reorg to expose register get/set functions.

1999-10-08  Simon Fitzmaurice <[e-mail]>
	* cdl\interrupts.cdl: Quoted '[' and ']' (significant in TCL and thus CDL)

1999-10-08  Jesper Skov  <[e-mail]>

	* cdl/interrupts.cdl: Added
	CYGIMP_HAL_COMMON_INTERRUPTS_IGNORE_SPURIOUS.

1999-09-22  Simon FitzMaurice <[e-mail]>

	* cdl\hal.cdl : add priority field to "extras.o" rule

1999-09-21  Gary Thomas  <[e-mail]>

	* src/thread-packets.c: Fix some typos in comments.

1999-09-15  Jesper Skov  <[e-mail]>

	* src/hal_stub.c: Override generic GDB interrupt functions for
	ARM. Need them to be thumb aware. 

1999-09-13  Gary Thomas  <[e-mail]>

	* include/pkgconf/hal.h: Add new config option to allow spurious
	interrupts to be ignored by the HAL.

	* src/generic-stub.c (__process_packet): Build in version string
	(date/time) for stubs in ROM to be returned via 'd' packet.

1999-09-09  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/hal.h (CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS): Rename
	CYGPKG_HAL_MN10300_SIM to CYGPKG_HAL_MN10300_AM31_SIM

1999-09-07  Nick Garnett  <[e-mail]>

	* src/dbg-threads-syscall.c (dbg_currthread_id): Fixed to return
	zero if dbg_currthread() returns false. Previously it could have
	returned a random value which would have made GDB think there had
	been a thread switch when there hadn't. It was particularly prone
	to do this in configurations where the kernel was absent.

1999-09-01  Gary Thomas  <[e-mail]>

	* include/pkgconf/hal.h: Always include target and platform package
	include (pkgconf) files.

1999-08-26  Jonathan Larmour  <[e-mail]>

	* src/generic-stub.c (__hex2mem_helper):
	Use target_register_t when casting to address type, rather than long
	Since the compiler can choose arbitrary alignment of unions, force
	to use byte array only
	Restore use of loop termination test for *hexMemSrc, just in case
	since that's how it used to be
	Increment destination, not source at end of loop
	
	(__mem2hex_helper):
	Use target_register_t when casting to address type, rather than long.
	Since the compiler can choose arbitrary alignment of unions, force
	to use byte array only. Therefore use single __read_mem_safe() call
	
	* src/hal_stub.c (__do_copy_mem): Reassign back from dst/src at start
	of each	"if" clause in case we go round the loop again.

1999-08-24  Gary Thomas  <[e-mail]>

	* src/hal_stub.c (__do_copy_mem): Move temp variables to top of
	function - potentially safer if there is an error.

1999-08-23  Jonathan Larmour  <[e-mail]>

	* src/generic-stub.c (__process_packet): For 'g' and 'G' packets,
	when the register size differs from sizeof(target_register_t) we must
	adjust according to the endianness 

	* include/hal_stub.h: Ensure __LITTLE_ENDIAN__ is defined on
	little-endian targets

	* src/hal_stub.c (__build_t_packet): Use the correct register sizes
	for PC and SP rather than assuming they are the same as target_register_t

1999-08-23  Gary Thomas  <[e-mail]>

	* include/generic-stub.h: Change prototypes for internal functions.

	* src/hal_stub.c (__do_copy_mem): 
	* src/generic-stub.c (__mem2hex_helper): Rework to perform aligned,
	multi-byte operations when conditions allow.  This should handle
	most "hardware register" access cases.  Note: there currently is
	no good way to force GDB to require/use such accesses.

1999-08-17  Jonathan Larmour  <[e-mail]>

	* tests/intr.c (cyg_start): Use CYG_TEST_NA rather than a pass saying
	it's inapplicable

1999-08-16  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/hal.h: Rename CYG_HAL_MN10300_AM32_STDEVAL1 to
	CYG_HAL_MN10300_AM31_STDEVAL1

1999-08-13  Nick Garnett  <[e-mail]>

	* src/hal_stub.c: Removed superfluous trace() extern.

1999-08-12  Nick Garnett  <[e-mail]>	

	Imported following changes from AM33 branch:
	
    1999-07-27  Nick Garnett  <[e-mail]>

	* src/hal_stub.c: Added support for 1 byte breakpoints.
	Removed	invalidates for cache flushes - I am not entirely sure why
	we have these here, since HAL_DCACHE_SYNC() should do what we
	need, and these invalidates are causing a problem on the MIPS and
	MN10300 targets.

	* include/pkgconf/hal.h: Added Monitor selection for AM33.

    1999-06-29  Nick Garnett  <[e-mail]>

	organization.

1999-07-02  Jesper Skov  <[e-mail]>
        PR20157
	* tests/cache.c: Print stride values, preventing timeout on slow
	targets.

1999-06-28  Jesper Skov  <[e-mail]>

	* include/pkgconf/hal.h (CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT):
	Fixed parent.

1999-06-24  Jonathan Larmour  <[e-mail]>

	* include/pkgconf/hal.h: Clarify descriptions of
	CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT and
	CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT.

1999-06-17  Nick Garnett  <[e-mail]>

	* include/pkgconf/hal.h: Added CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT
	to enable inclusion of ^C interrupt handler. Added CDL to control
	it.

1999-06-10  Hugo Tyson  <[e-mail]>

	* include/pkgconf/hal.h: Add support for the PowerPC target MBX860
	platform, CYG_HAL_POWERPC_MBX.

1999-06-10  Gary Thomas  <[e-mail]>

	* src/hal_stub.c: Need to init register pointer.

1999-06-08  Jesper Skov  <[e-mail]>

	* include/pkgconf/hal.h: Renamed SH platform package to edk7708.

1999-05-28  Nick Garnett  <[e-mail]>

	* src/hal_stub.c (initHardware): Added call to
	HAL_STUB_PLATFORM_INIT if it is defined.

	* include/pkgconf/hal.h: Added a #undef for CYG_HAL_ROM_MONITOR,
	largely so that a stubrom permutation can define it.

1999-05-27  Nick Garnett  <[e-mail]>

	* src/hal_stub.c: Do not call HAL_ICACHE_INVALIDATE_ALL() and
	HAL_DCACHE_INVALIDATE_ALL() in __instruction_cache() and
	__data_cache() for MIPS targets. These macros are simply
	duplicates.

1999-05-27  Jesper Skov  <[e-mail]>

	* tests/cache.c:  Added handling of unified caches.

1999-05-25  Jonathan Larmour  <[e-mail]>

	of HAL_STUB_PLATFORM_STUBS_FIXUP macro.

1999-05-18  Jesper Skov  <[e-mail]>

	* src/hal_stub.c (hal_output_gdb_string): Added missing ;

1999-05-13  Nick Garnett  <[e-mail]>

	The following changes were all made on a branch and imported into
	the main trunk later.
	
    1999-05-11  Nick Garnett  <[e-mail]>

	* include/pkgconf/hal.h:

	the right size.

	* src/drv_api.c: Added cyg_interrupt_call_pending_DSRs() to keep
	HAL happy in non-kernel configurations.

    1999-04-21  Nick Garnett  <[e-mail]>

	* include/pkgconf/hal.h:
	Added VR4300 configury for ROM monitor use and inclusion of
	variant-specific configuration header. This needs some further
	tidying up.

	Use the new rules for generating libextras.a
