        handle exit.

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

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

        file conditional.

        one automatically.

        bugs in this macro.

        * src/vectors.S:

        * 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:

      simulator builds

        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

1998-12-10  Jesper Skov  <jskov@cygnus.co.uk>

        * include/hal_cache.h (HAL_DCACHE_UNLOCK_ALL,

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

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

        * include/hal_cache.h:
        Added volatile keyword to appropriate places to prevent compiler
        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

        CYGIMP_HAL_COMMON_INTERRUPTS_CHAIN.

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

        PR 17153

        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.

        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

        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.

Fri Aug 28 10:09:03 1998  Jonathan Larmour  <jlarmour@cygnus.co.uk>

        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  <nickg@cygnus.co.uk>

        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>
