2003-01-31  Mark Salter  

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

        handle exit.

2002-12-06  Mark Salter  

        * 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  

        * 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  

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

        __do_syscall.

        * 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.

        to cyg_hal_exception_handler() to enable further decoding.

        * src/hal_misc.c (cyg_hal_exception_handler):

        Added extra argument to pass ISR register value. Now decodes ISR

        * src/vectors.S:

        * src/hal_misc.c:

        * src/hal_misc.c (cyg_hal_dcache_store):

        * include/hal_cache.h (HAL_DCACHE_STORE):

        DCACHE store operation needs 4 register variables. Put it in a

        separate function to ensure registers are availble.

1999-05-21  Hugo Tyson  

        * include/hal_intr.h: Define HAL_INTERRUPT_STACK_BASE and

        HAL_INTERRUPT_STACK_TOP so that stack usage macros in

        kernel/.../stackmon.hxx can work.

        * src/vectors.S (cyg_interrupt_stack_base): Define this symbol for

        the interrupt stack and its friend for the stack top so that we

        can publish them with nice names.

1999-05-13  Hugo Tyson  

        * include/hal_arch.h (HAL_THREAD_INIT_CONTEXT): Align stack

        (rather conservatively) before use.

        * src/PKGconf.mak:

        Remove the -n argument to tail, it does not appear to be required

        on any supported host and causes problems with some

        implementations of tail.

1999-04-20  Jonathan Larmour  

        * include/hal_cache.h:

        (HAL_DCACHE_IS_ENABLED) (HAL_ICACHE_IS_ENABLED): Add these new macros

        variables

        Ensure the cache has finished its operation before exitting.

        (HAL_DCACHE_INVALIDATE_ALL) (HAL_ICACHE_INVALIDATE_ALL): Make

        variables register variables.

        Re-enable cache if it was enabled on entry.

        (HAL_DCACHE_WRITE_MODE): Make variables register variables.

        Re-enable data cache if it was enabled on entry.

        Ensure the cache has finished its operation before exitting.

        (HAL_DCACHE_STORE): Make variables register variables.

        Separate parts of cyg_hal_invoke_constructors() out into new functions

        cyg_hal_enable_caches() and cyg_hal_debug_init() so that

        cyg_hal_invoke_constructors() can be called again safely if

        necessary

        Fix for PR19642

1999-04-14  Jonathan Larmour  

        * src/PKGconf.mak (EXTRAS): Don't generate extras.o here any more

        to a 4 byte boundary. Fixes PR 19695.

        * include/hal_cache.h: Added include of hal.h and a test that a

        valid set of macros have been added.

1999-03-26  Gary Thomas  

        * include/hal_arch.h (CYGNUM_HAL_STACK_SIZE_MINIMUM): Be a little

        more generous since this stack should allow at least a kernel API

        call which could be at least 4 levels deep.

1999-03-23  Nick Garnett  

        * include/hal_arch.h:

        Modified stack size definitions to be more accurate.

        * src/hal_misc.c:

        * src/vectors.S:

        and memory access exceptions. See the comments in

        __default_nmi_vsr in vector.S for details.

1999-03-17  John Dallaway  

        * src/PKGconf.mak: Remove dependence on echo '-e' switch.

1999-03-10  Jesper Skov  

        * include/hal_intr.h (HAL_INTERRUPT_ATTACH): Added.

1999-03-08  Nick Garnett  

        * src/mn10300.ld:

        Added alignment before definition of __DEVTAB__.

        * src/mn10300.ld: Clean up I/O package changes.

1999-03-04  Jonathan Larmour  

        * src/mn10300.ld:

        Unconditionalize use of libextras.a and add to GROUP()

1999-02-25  Nick Garnett  

        * src/hal_misc.c:

        Now tests for whether the kernel is present before trying to use

        patch_dbg_syscalls().

        * include/hal_intr.h (HAL_INTERRUPT_CONFIGURE): fixed some compile

        bugs in this macro.

        * src/vectors.S:

        Changed label used to access scheduler lock to one that is not

        mangled by C++. This is intended to make support for interrupt

        handling in non-kernel configurations easier.

1999-02-20  Jonathan Larmour  

        * include/hal_arch.h:

        Rename deliver_exception() -> cyg_hal_deliver_exception()

        QA improvements

        * include/hal_intr.h:

        Reorganise vector/interrupt/exception names according to purpose

        QA improvements

        * src/hal_misc.c:

        Rename deliver_exception() -> cyg_hal_deliver_exception()

        Rename CYG_VECTOR_* according to hal_intr.h changes above

        QA improvements

        * src/vectors.S:

        Rename exception_handler() -> cyg_hal_exception_handler()

1999-02-16  Jesper Skov  

        * src/vectors.S: Changed set_debug_traps to initialize_stub.

        * src/mn10300_stub.c:

        * include/mn10300_stub.h:

        Cleaned up to only include arch specific stub code.

1999-02-15  Jesper Skov  

        * include/basetype.h: Added CYG_LABEL_NAME macro.

1999-02-11  Nick Garnett  

        * include/hal_cache.h (HAL_DCACHE_STORE):

        Added "register" keywords to the variables used in this macro. If

        these are not in registers then when the cache is disabled, they

        can be stranded in the cache and the random values in main memory

        are used instead. This is only a problem when optimization is

        disabled; under optimization the compiler puts these variables

        into registers as a matter of course.

        Fixes PR 19165.

        (HAL_DCACHE_SYNC): Divide cache size by number of ways to

        calculate correct size to pass to HAL_DCACHE_STORE().

1999-02-05  John Dallaway  

        * src/mn10300.ld: Add LMA_EQ_VMA macro definition.

1999-02-01  Nick Garnett  

        * include/hal_cache.h: Fixed implementation of HAL_DCACHE_STORE() so

        that it now works, and changed implementation of HAL_DCACHE_SYNC()

        to use it.

        Fixes PR 18577 and is a better fix to 18849.

1999-01-27  Nick Garnett  

        * include/hal_intr.h:

        * src/vectors.S:

        Allow for NMI vectors in ISR table when using chained

        interrupts. This largely consists of moving the interrupt vector

        slots up by 3 entries.

1999-01-26  Hugo Tyson  

        * src/mn10300.ld:

        PR 17153

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

        value to isr.

1998-09-09  Nick Garnett  

        * 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):

        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.

        * include/pkgconf/hal_mn10300.h:

        New header file for architecture-specific configuration options

        * 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  

        * 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.

1998-08-28  Bart Veer  

        * src/vectors.S, src/context.S, src/hal_misc.c, include/hal_intr.h:

        Updated for new kernel configuration option symbol names

Fri Aug 28 10:09:03 1998  Jonathan Larmour  

        * src/hal_misc.c:

        rename __main() to cyg_hal_invoke_constructors() and remove

        initialised test

        Change call of __main() to cyg_hal_invoke_constructors(), and call

        of main() to cyg_start()

1998-08-25  Nick Garnett  

        * src/vectors.S:

        Now pass pointer to saved registers as third argument to

        interrupt_end().

        Added macros to support GDB.

1998-08-21  Nick Garnett  

        * 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  

        * src/hal_misc.c (__main):

        Add void to function prototypes to silence warnings

        Now includes cyg_type.h rather than ktypes.h.

        * src/context.S:

        * src/vectors.S:

        * src/hal_misc.c:

        Now uses hal.h rather than kernel.h.
