2003-01-31  Mark Salter  <msalter@redhat.com>

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

2002-12-06  Mark Salter  <msalter@redhat.com>

        * 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  <jlarmour@redhat.com>

        * 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  <jlarmour@redhat.com>

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

2001-11-16  Nick Garnett  <nickg@redhat.com>

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

2001-10-16  David Howells  <dhowells@redhat.com>

        * 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  <dhowells@redhat.com>

        * 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  <dhowells@redhat.com>

        * include/mn10300_stub.h: added syscall handling.

        one automatically.

2000-11-30  Drew Moseley  <dmoseley@redhat.com>

        * 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  <jskov@redhat.com>

        * src/hal_misc.c: Update __mem_fault_handler declaration.

        bugs in this macro.

        * src/vectors.S:

        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  <jskov@cygnus.co.uk>

        * 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  <jskov@cygnus.co.uk>

        * include/basetype.h: Added CYG_LABEL_NAME macro.

1999-02-11  Nick Garnett  <nickg@cygnus.co.uk>

        * 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  <jld@cygnus.co.uk>

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

1999-02-01  Nick Garnett  <nickg@cygnus.co.uk>

        * 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  <nickg@cygnus.co.uk>

        * 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  <hmt@masala.cygnus.co.uk>

        * src/mn10300.ld:
        Add copyright notice.  (Though these files will later be generated

1999-01-25  Jesper Skov  <jskov@cygnus.co.uk>

        * src/mn10300_stub.c (__build_t_packet): Rewrote fix me text. Added PR
        number, but otherwise left the note.

        Shorten needlessly long lines
        Remove all traces of non-CYG_KERNEL_USE_INIT_PRIORITY code

1999-01-14  John Dallaway  <jld@cygnus.co.uk>

        pointer to base of vector rather than a single vector entry.

1999-01-12  John Dallaway  <jld@cygnus.co.uk>

      * src/mn10300.ld: new linker script for MLT
      * src/PKGconf.mak: add mn10300.ld rules for MLT

1998-12-15  Jesper Skov  <jskov@cygnus.co.uk>

        * include/hal_arch.h: 
        * src/context.S (_hal_setjmp, _hal_longjmp):
        Added CYGARC definitions for jmpbuf entries.
        
1998-12-10  Jesper Skov  <jskov@cygnus.co.uk>

        * include/hal_cache.h (HAL_DCACHE_UNLOCK_ALL,
        HAL_ICACHE_UNLOCK_ALL): Added.

1998-11-25  Jesper Skov  <jskov@cygnus.co.uk>

1998-11-16  Nick Garnett  <nickg@cygnus.co.uk>

        * include/hal_cache.h:

        optimizing out cache control register access.

1998-10-21  Nick Garnett  <nickg@cygnus.co.uk>

        * include/hal_intr.h (HAL_CLOCK_READ):

        Altered ifdefs to allow builds without kernel.

Thu Sep 24 18:14:19 1998  Jesper Skov  <jskov@cygnus.co.uk>

        * include/hal_intr.h: Read the interrupt control registers back
        after writing to them to ensure that the value is not sitting in
        the store buffer.
        Also put _ around variable names in HAL_INTERRUPT_CONFIGURE for
        consistency.
        
1998-09-24  Nick Garnett  <nickg@cygnus.co.uk>

        * include/hal_intr.h:
        Inverted mask for level in HAL_INTERRUPT_SET_LEVEL().

        * src/vectors.S:
        Added correct implementations of decode_interrupt macro for
        chained interrupt processing.
        Modified call to cyg_instrument() to pass table offset as well as
        vector number.
        Include <pkgconf/kernel.h> to allow call to cyg_instrument() to be
        enabled.

1998-09-14  Bart Veer  <bartv@cygnus.co.uk>

        * src/PKGconf.mak:
        Made vectors.o dependent on the various files that can contain
        makefile variables or rules. This is needed after changes to
        pkgconf.tcl for PRs 17195 and 17286.

Mon Sep 14 11:08:40 1998  Jesper Skov  <jskov@lassi.cygnus.co.uk>
        PR 17230
        
        * include/hal_intr.h: 
        * src/vectors.S: 
        Replaced CYGIMP_KERNEL_INTERRUPTS_CHAIN with new
        CYGIMP_HAL_COMMON_INTERRUPTS_CHAIN.

1998-09-12  Bart Veer  <bartv@cygnus.co.uk>

        * include/pkgconf/hal_mn10300.h:
        Added missing descriptions (PR 17184)

        * src/hal_misc.c (exception_handler): 
        Sort out exception handling options (PR 16953)

Thu Sep 10 20:24:02 1998  Hugo Tyson  <hmt@cygnus.co.uk>

        * src/vectors.S (__default_interrupt_vsr): 
        Fix a bug.  Wrong offset when restoring the PSW tends to screw
        things up rather.

Thu Sep 10 15:12:21 1998  Jesper Skov  <jskov@lassi.cygnus.co.uk>
        PR 17153

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

1998-09-09  Nick Garnett  <nickg@cygnus.co.uk>

        * 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):
        Added call to patch_dbg_syscalls() for Cygmon hosted builds.

        * src/context.S (_hal_thread_switch_context):
        Adjust thread context so that it has the same structure as the
        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.

1998-09-04  Bart Veer  <bartv@cygnus.co.uk>

        * src/vectors.S (__default_interrupt_vsr):

        * src/vectors.S:
        Fixed offset bug in __trap.
        Changed conditionals on runtime initialisation of VSR table to not
        do it in simulated targets.

1998-09-02  Bart Veer  <bartv@cygnus.co.uk>

        * include/pkgconf/hal_mn10300.h:
        New header file for architecture-specific configuration options

        * tests/PKGconf.mak: 
        * src/PKGconf.mak: 
        Sort out package naming conventions.

1998-09-02  Nick Garnett  <nickg@cygnus.co.uk>

        * 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  <nickg@cygnus.co.uk>

        * 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  <bartv@cygnus.co.uk>

        * 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  <jlarmour@cygnus.co.uk>

        * src/hal_misc.c: 
        rename __main() to cyg_hal_invoke_constructors() and remove
        initialised test

        * src/vectors.S (_start): 
        Change call of __main() to cyg_hal_invoke_constructors(), and call
        of main() to cyg_start()

1998-08-25  Nick Garnett  <nickg@cygnus.co.uk>

        * src/vectors.S:
        Now pass pointer to saved registers as third argument to
        interrupt_end().

        * include/hal_arch.h:
        Added macros to support GDB.

1998-08-21  Nick Garnett  <nickg@cygnus.co.uk>

        * 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  <jlarmour@cygnus.co.uk>

        * src/hal_misc.c (__main): 
        Add void to function prototypes to silence warnings

        * src/vectors.S:
        Reorgnized ifdefs to better support kernel porting.
