2002-10-31      Joel Sherrill <joel@OARcorp.com>

        * src/heapgetinfo.c: Fixed comment.
        * src/mpci.c: Removed warning.

2002-10-28      Joel Sherrill <joel@OARcorp.com>

        * src/threadhandler.c: Prototype _init() and _main() if they are needed
        to avoid a warning.

2002-08-14      Joel Sherrill <joel@OARcorp.com>

        * macros/rtems/score/coremsg.inl: Add <string.h> to remove warning.
        * src/threadidlebody.c: Add return 0 to avoid warning.

2002-08-07      Chris Johns <ccj@acm.org>

        * src/coretodset.c: Correct calculation of ticks until next section
        boundary.  It was incorrectly based upon current time not the
        time that is being set.

2002-07-31      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * src/Makefile.am: Build into libscore.a.

2002-07-22      Joel Sherrill <joel@OARcorp.com>

        * include/rtems/score/apimutex.h (_API_Mutex_Lock): Per PR253
        add the missing _ISR_Disable.  This fix was already applied to
        the old location (c/src/exec/score/...).

2002-07-22      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * src/Makefile.am: Use .$(OBJEXT) instead of .o.

2002-07-16      Joel Sherrill <joel@OARcorp.com>

        * macros/rtems/score/object.inl: Corrected typos in 
        _Objects_Open, _Objects_Close, and _Objects_Namespace_remove.

2002-07-05      Joel Sherrill <joel@OARcorp.com>

        * macros/rtems/score/object.inl: Corrected implementation of
        _Objects_Open, _Objects_Close, and _Objects_Namespace_remove
        to be consistent with the inline implementation.

2002-07-01    Joel Sherrill <joel@OARcorp.com>

        * Mega patch merge to change the format of the object IDs to
        loosen the dependency between the SCORE and the various APIs.
        There was considerable work to simplify the object name management
        and it appears that the name_table field is no longer needed.
        This patch also includes the addition of the internal mutex
        which is currently only used to protect some types of allocation
        and deallocation.  This significantly can reduce context 
        switch latency under certain circumstances.  In particular,
        some heap/region operations were O(n) and had dispatching
        disabled.  This should help enormously.  With this merge,
        the patch is not as clean as it should be.  In particular,
        the documentation has not been modified to reflect the new object
        ID layout, the IDs in the test screens are not updated, and
        _Objects_Get_information needs to be a real routine not inlined.
        As part of this patch a lot of MP code for thread/proxy blocking
        was made conditional and cleaned up.
        * include/Makefile.am, include/rtems/score/coremsg.h,
        include/rtems/score/coremutex.h, include/rtems/score/coresem.h,
        include/rtems/score/object.h, include/rtems/score/threadq.h,
        inline/rtems/score/object.inl, inline/rtems/score/thread.inl,
        macros/rtems/score/object.inl, src/Makefile.am, src/coremsg.c,
        src/coremutex.c, src/coresem.c, src/mpci.c,
        src/objectcomparenameraw.c, src/objectextendinformation.c,
        src/objectinitializeinformation.c, src/objectnametoid.c,
        src/thread.c, src/threadclose.c, src/threadget.c, src/threadq.c,
        src/threadqextractwithproxy.c: Modified as part of above.
        * include/rtems/score/apimutex.h, src/objectgetnoprotection.c: New
        files.

2001-05-17      Joel Sherrill <joel@OARcorp.com>

        * macros/rtems/score/thread..inl: Implemented missing routines
        for new libc reentrancy support.

2002-05-15      Chris Johns <ccj@acm.org>

        * include/rtems/score/thread.h, inline/rtems/score/thread.inl,
        src/threaddispatch.c, src/threadinitialize.c: 
        Move the C library re-enterrant support directly into
        the thread dispatch code. RTEMS needs libc and so requiring
        libc to use a user extension with its overhead is not the best
        solution. This patch lowers the overhead to 2 pointer moves.

2002-05-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * include/Makefile.am: Work-around to autoconf-2.53 adding PACKAGE_*
        to autoheaders - sed out *PACKAGE* from cpuopts-tmp.h.

2001-05-14      Till Straumann <strauman@slac.stanford.edu>

        * src/threaddispatch.c, src/threadhandler.c: Per PR211 fix
        saving/restoring floating point context.  The fpsave and fprestore
        routines are only used in a executing context which _is_ fp and hence
        has the FPU enabled. The current behavior required the FPU always to
        be on which is very dangerous if lazy context switching is used.  
        [Joel Note: Some ports explicitly enabled the FPU in the FP save and
        restore routines to avoid this.]

        The patch also makes sure (on powerpc only) that the FPU is disabled
        for integer tasks. Note that this is crucial if deferred fp context
        switching is used. Otherwise, fp context corruption may go undetected!
        Also note that even tasks which merely push/pop FP registers to/from
        the stack without modifying them still MUST be FP tasks - otherwise
        (if lazy FP context switching is used), FP register corruption (of
        other, FP, tasks may occur)!

        Furthermore, (on PPC) by default, lazy FP context save/restore
        is _disabled_.

2001-04-26      Joel Sherrill <joel@OARcorp.com>

        * src/objectcomparenamestring.c: Fix typos.
 
2001-04-26      Joel Sherrill <joel@OARcorp.com>

        * include/rtems/score/object.h, inline/rtems/score/object.inl, 
        src/objectcomparenamestring.c: Address PR81 that
        reworked POSIX message queues to add a descriptor separate from
        the underlying message queue.  This allows non-blocking to follow
        the "open" not the underlying queue.   As part of debugging this
        it became clear that _Objects_Compare_name_string was broken
        and a simple version using strncmp() was substituted.
 
2002-04-18      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * include/rtems/system.h: Remove targopts.h.

2002-04-17      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * include/rtems/system.h: Add the sparc to the target supporting
        multlibs.

2002-04-16      Chris Johns <ccj@acm.org>

        * src/threadinitialize.c: Per PR181, clear the array of user extension
        pointers. This lets user extensions that have hooked the switch handler
        know if a task has been processed by the user extension before. If a
        user extension is created after a task is started it may not know it.

2002-04-12      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * include/rtems/system.h: Add i386 to multilib-able targets.

2001-04-11      Joel Sherrill <joel@OARcorp.com>

        
        * macros/rtems/score/userext.inl: Now works after merging patch for
        functionality requested in PR174.
        * inline/rtems/score/userext.inl: Added a comment explaining the
        order in which routines appear since it is not the obvious order.
 
2002-04-08      Chris Johns <ccj@acm.org>

        * Per PR141 and PR174, make task switch extension its own list and
        fix all odd problems introduced by providing macro version.
        * inline/rtems/score/userext.inl: Fix.

2001-04-08      Joel Sherrill <joel@OARcorp.com>

        * macros/rtems/score/object.inl: Corrected arguments.
 
2001-04-08      Joel Sherrill <joel@OARcorp.com>

        * macros/rtems/score/userext.inl: Updated to reflect modifications
        to inline version from PR142.
        * inline/rtems/score/userext.inl: Cleanup as side-effect of above.
 
2002-04-08      Chris Johns <ccj@acm.org>

        * Per PR142, make task switch extension its own list.
        * include/rtems/score/userext.h: Reflect above by adding 
        User_extensions_Switch_control and adding it to User_extenions_Control.
        * inline/rtems/score/userext.inl: Allocate all memory in one chunk
        to minimize overhead.  Address processing dedicated switch chain.

2002-04-08      Chris Johns <ccj@acm.org>

        * Per PR142, make task switch extension its own list.
        * include/rtems/score/userext.h: Reflect above by adding 
        User_extensions_Switch_control and adding it to User_extenions_Control.
        * inline/rtems/score/userext.inl: Allocate all memory in one chunk
        to minimize overhead.  Address processing dedicated switch chain.

2002-03-27      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * cpu/Makefile.am: Remove AUTOMAKE_OPTIONS.
        * src/Makefile.am: Remove AUTOMAKE_OPTIONS.
        * Makefile.am: Remove AUTOMAKE_OPTIONS.
        * include/Makefile.am: Remove AUTOMAKE_OPTIONS.
        * inline/Makefile.am: Remove AUTOMAKE_OPTIONS.
        * macros/Makefile.am: Remove AUTOMAKE_OPTIONS.

2002-01-29      Joel Sherrill <joel@OARcorp.com>

        * include/rtems/score/watchdog.h: Added WATCHDOG_MAXIMUM_INTERVAL.

2002-01-19      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * include/rtems/system.h: Fix typo in yesterday's change:
        RTEMS_MULTILIBS.

2001-01-18      Joel Sherrill <joel@OARcorp.com>

        * include/rtems/system.h: Only include cpuopts.h when building a
        multilib configuration.  Some ports still need targopts.h but this
        small modification lets those ports work non-multilib while 
        fixing being fixed for multilib.
        
2002-01-04      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * include/rtems/seterr.h: Add do {..} while (0) in defines.
        Rename set_errno_and_return_minus_one into
        rtems_set_errno_and_return_minus_one.

2001-12-19      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * inline/rtems/score/object.inl, macros/rtems/score/object.inl: Add
        add casts to Objects_Id in _Objects_Build_ids to avoid implicit
        typecasts from enum to int16 on bit16 targets (here: h8300).

2001-12-19      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * src/Makefile.am: Add multilib support.

2001-11-28      Joel Sherrill <joel@OARcorp.com>,

        This was tracked as PR91.
        * include/rtems/score/isr.h, inline/rtems/score/isr.inl,
        macros/rtems/score/isr.inl: Modified to allow any port to provide 
        its own implementation of the macro _ISR_Is_in_progress.  If the
        port overrides this macro, it must provide a non-inlined function
        implementation.

2001-11-20      Joel Sherrill <joel@OARcorp.com>

        * src/threadhandler.c: When __USE__MAIN__ is defined by the toolset,
        invoke the global constructors via __main.  Reported as tested by 
        Alexandra Kossovsky <sasha@oktet.ru> and  Victor V. Vengerov
        <vvv@oktet.ru> in conjunction with a new set of tool RPMs
        (gcc2.95.3newlib1.9.0-3).  This was tracked as GNATS PR tools/84.

2001-11-07      Joel Sherrill <joel@OARcorp.com>

        Reported by Todor.Todorov@barco.com and tracked as PR36.
        * include/rtems/score/object.h: Added prototype for
        _Objects_Get_by_index().
        * src/objectget.c, src/objectgetisr.c: Corrected procedure for
        getting index from Id so it is correct and optimal for both single
        and multiprocessor configurations.

2001-10-22      Joel Sherrill <joel@OARcorp.com>

        * src/threadhandler.c: Use __USE_INIT_FINI__ since USE_INIT_FINI
        pollutes the application namespace.

2001-10-16      Joel Sherrill <joel@OARcorp.com>

        * .cvsignore: Add stamp-h.in.

2001-10-16      Joel Sherrill <joel@OARcorp.com>

        * include/Makefile.am: Fixed path to cpuopts-tmp.h.

2001-10-16      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * include/rtems/Makefile.am: Remove.
        * include/rtems/Makefile.am: Remove.
        * include/Makefile.am: Handle subdirs, require automake-1.5.
        * macros/rtems/Makefile.am: Remove.
        * macros/rtems/score/Makefile.am: Remove.
        * macros/Makefile.am: Handle subdirs, require automake-1.5.
        * inline/rtems/Makefile.am: Remove.
        * inline/rtems/score/Makefile.am: Remove.
        * inline/Makefile.am: Handle subdirs, require automake-1.5.
        * Makefile.am: require automake-1.5

2001-09-28      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * include/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='.
        * include/rtems/Makefile.am: Use 'PREINSTALL_FILES ='.
        * inline/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='.
        * macros/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='.

2001-09-27      Eric Norum <eric.norum@usask.ca>

        * src/threadhandler.c: Now process C++ global constructors
        (_init) as part of the first task execution not in BSP space.
        This depends on the toolset defining USE_INIT_FINI so you
        have to have the right toolset version.

2001-09-23      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * include/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='.
        * include/rtems/Makefile.am: Use 'PREINSTALL_FILES ='.
        * inline/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='.
        * macros/rtems/score/Makefile.am: Use 'PREINSTALL_FILES ='.

2001-08-30      Joel Sherrill <joel@OARcorp.com>

        *  src/coremutex.c, src/coremutexseize.c, src/coremutexsurrender.c,
        inline/rtems/score/coremutex.inl: The per thread field resource_count
        should only be manipulated when a mutex is priority ceiling or
        priority inherit.  This was reported by Chris Johns <ccj@acm.org>
        who also noticed that the use of switches for all disciplines
        generated less efficient code than using explicit tests for the one
        or two cases we were really interested in.  Further review of his
        modifications made it apparent that the "isa" methods to test mutex
        discipline were not being used so this modification was swept into
        the code as well.

2001-08-30      Joel Sherrill <joel@OARcorp.com>

        * src/coremutexseize.c: Add missing code for proper handling
        of nesting acquisitions.  This only impacts building with
        inlines disabled on the source with the "fast mutex" optimizations.
        This was post the 4.5 branch and did not impact released versions.

2001-08-16      Joel Sherrill <joel@OARcorp.com>

        * src/coremutexsurrender.c: Use holder thread not executing
        thread because even though they may and often are the same
        it is not guaranteed unless the proper attribute is set.

2001-08-16      Joel Sherrill <joel@OARcorp.com>

        * include/rtems/score/coremsg.h, src/coremsgsubmit.c: Add a new
        return status to account for blocking sends.  Otherwise, the
        caller will think that the returned message status will have
        the ultimate results of the operation.  If the send times out,
        the final status will be in the return_code of the thread.

2001-08-09      Joel Sherrill <joel@OARcorp.com>

        * include/rtems/score/coremsg.h, inline/rtems/score/coremsg.inl,
        src/coremsgsubmit.c: Unblocking message queue operations should
        NOT use _Thread_Executing for return status since it is permissible
        to invoke message send operations from an ISR.  This was reported
        by Suvrat Gupta <suvrat@utstar.com>.

2000-05-25      Sergei Organov <osv@javad.ru>

        * macros/rtems/score/coresem.inl, inline/rtems/score/coresem.inl:
        Cut and paste problem incorrectly enabled interrupts twice with
        the first time being too early.

2001-05-09      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * include/rtems/score/.cvsignore: Add stamp-h, cpuopts.h,
        cpuopts.h.in, cpuopts-tmp.h.

2001-02-03      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * include/rtems/Makefile.am, include/rtems/score/Makefile.am,
        inline/rtems/score/Makefile.am, macros/rtems/score/Makefile.am
        Apply include_*HEADERS instead of H_FILES.

2001-01-29      Joel Sherrill <joel@OARcorp.com>

        * src/objectextendinformation.c: Added include of string.h to
        eliminate warning.

2001-01-08      Joel Sherrill <joel@OARcorp.com>

        * src/threadinitialize.c: Fix my bad hack of Ralf's fp_area
        warning removal patch. :(

2001-01-08      Ralf Corsepius <corsepiu@faw.uni-ulm.de>

        * src/threadinitialize.c: Removed warning.

2001-01-03      Joel Sherrill <joel@OARcorp.com>

        * src/isr.c: Modify to properly dereference _ISR_Vector_table
        now that it is dynamically allocated.

2000-12-19      Joel Sherrill <joel@OARcorp.com>

        * src/isr.c: Allocate the _ISR_Vector_table all the time not just when
        we are allocating an interrupt stack.

2000-12-13      Joel Sherrill <joel@OARcorp.com>

        * include/rtems/score/isr.h, src/isr.c: Allocate it from the
        workspace rather than explicitly declaring it.  This allows
        the size to be a non-constant from the perspective of score/cpu.

2000-12-01      Joel Sherrill <joel@OARcorp.com>

        * macros/rtems/score/coresem.inl: Removed comments since convention
        calls for comments to be in inline versin.
        * macros/rtems/score/object.inl (Objects_Get_local_object): Fixed
        style to use _ prefix on variable names and use parentheses.
        * macros/rtems/score/object.inl (_Objects_Namespace_remove): Added.

2000-11-30      Joel Sherrill <joel@OARcorp.com>

        * General effort to make things compile with macros not inlines
        * inline/rtems/score/coremutex.inl: Added comment indicating
        for macros there is another copy of
        _CORE_mutex_Seize_interrupt_trylock() in src/coremutexseize.c.
        * src/coremutexseize.c: Added body of
        _CORE_mutex_Seize_interrupt_trylock() for macro case.
        * macros/rtems/score/coremutex.inl: Added prototype for 
        _CORE_mutex_Seize_interrupt_trylock() since there is a real
        body when macros are enabled.
        * macros/rtems/score/coresem.inl: Added macro implementation of
        _CORE_semaphore_Seize_isr_disable.
        * macros/score/Makefile.am: Fixed typos.
        * rtems/score/address.inl: Correct macro implementation of
        _Addresses_Is_aligned() so it would compile.
        * macros/rtems/score/coremsg.inl: Added closing parentheses.
        
2000-11-28      Chris Johns <ccj@acm.org>

        * src/heapallocate.c: Do not allow the size to overflow when
        adjusting it.  A test allocated a stack of -1 (~0). This
        actually resulted in a stack being allocated but with a
        size of 0xb. The allocator did not test the size to see if
        it rolled through 0 and so allowed the allocation to happen, the
        thread to get created. The task crashed as you would expect.

2000-11-02      Joel Sherrill <joel@OARcorp.com>

        * include/rtems/system.h: Use proper conditional (RTEMS_POSIX_API)
        so prototypes for POSIX_MP_NOT_IMPLEMENTED(), POSIX_NOT_IMPLEMENTED(),
        POSIX_BOTTOM_REACHED() are actually included.

2000-11-02      Joel Sherrill <joel@OARcorp.com>

        * include/rtems/system.h: Add prototypes for POSIX_MP_NOT_IMPLEMENTED(),
        POSIX_NOT_IMPLEMENTED(), POSIX_BOTTOM_REACHED() removed from newlib.

2000-10-18      Nick Simon <Nick.SIMON@syntegra.bt.co.uk>

        * src/heapgetinfo.c, include/rtems/score/heap.h, src/Makefile.am:
