+Mon Dec 17 17:02:12 2001  Nicola Pero  <nicola@brainstorm.co.uk>
+
+	* init.c (__objc_exec_class): Fixed bug in the loop on unclaimed
+	categories - when an unclaimed category was found, the loop was
+	doing two steps forward instead of one, so that in certain cases
+	it was failing to properly load all the categories.  (Reported
+	with fix by Alexander Malmberg <alexander@malmberg.org>).
+
+2001-11-14  Aldy Hernandez  <aldyh@redhat.com>
+
+	* encoding.c: Add target_flags.
+
+2001-11-07  Aldy Hernandez  <aldyh@redhat.com>

+
+Mon Oct 29 21:29:21 2001  Nicola Pero  <n.pero@mi.flashnet.it>
+
+	* class.c: Rewritten the class table to use optimized, lock-free
+	lookup.  This more than doubles the speed of class method

+	(class_table_replace), (class_table_get_safe),
+	(class_table_next), (class_table_print),
+	(class_table_print_histogram): New functions.

+	(__objc_resolve_class_links): Use class_table_next.
+	(class_pose_as): Use class_table_replace.

+
+	* gc.c: Removed the DEBUG declaration.
+
+Wed Jul 18 12:48:56 2001  Nicola Pero  <n.pero@mi.flashnet.it>
+
+	* thr.c (objc_mutex_lock): Invoke __objc_thread_id directly,
+	rather than through objc_thread_id, to save a function call.
+	(objc_mutex_trylock, objc_mutex_unlock, objc_condition_wait):
+	Ditto.
+
+Mon Jul 16 12:15:00 2001  Nicola Pero  <n.pero@mi.flashnet.it>
+
+	* objc/objc-api.h (object_is_class): Fixed - buggy code was trying
+	to cast an id to a Class, which can not be done.  Make the check
+	by using CLS_ISMETA on the class pointer instead.
+	(object_is_meta_class): Similar fix.
+
+2001-06-09  Alexandre Oliva  <aoliva@redhat.com>, Stephen L Moshier  <moshier@mediaone.net>

+	* acinclude.m4: Likewise.
+	* configure: Rebuilt.
+
+2001-06-08  Nicola Pero  <n.pero@mi.flashnet.it>
+
+	* THREADS: Explain that when we compile libobjc inside GCC, we
+	always use thr-objc.c as a backend, which uses GCC's thread code.
+
+2001-06-06  Richard Frith-Macdonald  <rrfm@gnu.org>
+
+	* init.c (__objc_send_message_in_list): When setting a new entry
+	in __objc_load_methods use the method IMP as key, but check to see
+	if the method is in the hashtable by looking at the IMP also.
+	Also ... call the method after adding it to the hashtable rather
+	than before ... thus preventing an obscure possibility of infinite
+	recursion if a +load method itself loads a subclass.
+
+2001-05-25  Ovidiu Predescu  <ovidiu@cup.hp.com>
+
+	* init.c (__objc_send_message_in_list): When setting a new entry
+	in __objc_load_methods use the method name as key, not the method
+	IMP (reported by Richard Frith-Macdonald <richard@brainstorm.co.uk>).

+
+2001-02-08  Geoffrey Keating  <geoffk@redhat.com>

+
+Wed Jan  3 00:49:10 2001  Ovidiu Predescu  <ovidiu@cup.hp.com>
+
+	* sendmsg.c: Added __objc_msg_forward, a hook that allows external
+	libraries to provide a function that returns the real forwarding
+	function. This can alleviate problems __builtin_apply() and
+	friends have on various platforms. (Solution suggested by Helge
+	Hess.)
+
+	* objc/objc-api.h: Define __objc_msg_forward.
+
+	* sendmsg.c: Define gen_rtx_REG.

+GNU Objective C notes
+*********************
+
+This document is to explain what has been done, and a little about how
+specific features differ from other implementations.  The runtime has
+been completely rewritten in gcc 2.4.  The earlier runtime had several
+severe bugs and was rather incomplete.  The compiler has had several
+new features added as well.
+
+This is not documentation for Objective C, it is usable to someone
+who knows Objective C from somewhere else.
+
+
+Runtime API functions
+=====================
+
+The runtime is modeled after the NeXT Objective C runtime.  That is,
+most functions have semantics as it is known from the NeXT.  The
+names, however, have changed.  All runtime API functions have names
+of lowercase letters and underscores as opposed to the
+`traditional' mixed case names.  
+	The runtime api functions are not documented as of now.
+Someone offered to write it, and did it, but we were not allowed to
+use it by his university (Very sad story).  We have started writing
+the documentation over again.  This will be announced in appropriate
+places when it becomes available.
+
+
+Protocols
+=========
+
+Protocols are now fully supported.  The semantics is exactly as on the
+NeXT.  There is a flag to specify how protocols should be typechecked
+when adopted to classes.  The normal typechecker requires that all
+methods in a given protocol must be implemented in the class that
+adopts it -- it is not enough to inherit them.  The flag
+`-Wno-protocol' causes it to allow inherited methods, while
+`-Wprotocols' is the default which requires them defined.
+
+
++load
+===========
+This method, if defined, is called for each class and category
+implementation when the class is loaded into the runtime.  This method
+is not inherited, and is thus not called for a subclass that doesn't
+define it itself.  Thus, each +load method is called exactly once by
+the runtime.  The runtime invocation of this method is thread safe.
+
+
++initialize 
+===========
+
+This method, if defined, is called before any other instance or class
+methods of that particular class.  For the GNU runtime, this method is 
+not inherited, and is thus not called as initializer for a subclass that 
+doesn't define it itself.  Thus, each +initialize method is called exactly 
+once by the runtime (or never if no methods of that particular class is 
+never called).  It is wise to guard against multiple invocations anyway 
+to remain portable with the NeXT runtime.  The runtime invocation of 
+this method is thread safe.
+
+
+Passivation/Activation/Typedstreams
+===================================
+
+This is supported in the style of NeXT TypedStream's.  Consult the
+headerfile Typedstreams.h for api functions.  I (Kresten) have
+rewritten it in Objective C, but this implementation is not part of
+2.4, it is available from the GNU Objective C prerelease archive. 
+   There is one difference worth noting concerning objects stored with
+objc_write_object_reference (aka NXWriteObjectReference).  When these
+are read back in, their object is not guaranteed to be available until
+the `-awake' method is called in the object that requests that object.
+To objc_read_object you must pass a pointer to an id, which is valid
+after exit from the function calling it (like e.g. an instance
+variable).  In general, you should not use objects read in until the
+-awake method is called.
+

+This file describes in little detail the modifications to the
+Objective-C runtime needed to make it thread safe. 
+
+First off, kudos to Galen Hunt who is the author of this great work.
+
+If you have an comments or just want to know where to
+send me money to express your undying gratitude for threading the
+Objective-C runtime you can reach Galen at:
+
+	gchunt@cs.rochester.edu
+
+Any questions, comments, bug reports, etc. should send email either to the
+GCC bug account or to:
+
+	Scott Christley <scottc@net-community.com>
+
+* Sarray Threading:
+
+The most critical component of the Objective-C runtime is the sparse array
+structure (sarray).  Sarrays store object selectors and implementations.  
+Following in the tradition of the Objective-C runtime, my threading
+support assumes that fast message dispatching is far more important
+than *ANY* and *ALL* other operations.  The message dispatching thus
+uses *NO* locks on any kind.  In fact, if you look in sarray.h, you
+will notice that the message dispatching has not been modified.
+Instead, I have modified the sarray management functions so that all
+updates to the sarray data structure can be made in parallel will
+message dispatching.  
+
+To support concurrent message dispatching, no dynamically allocated
+sarray data structures are freed while more than one thread is
+operational.  Sarray data structures that are no longer in use are
+kept in a linked list of garbage and are released whenever the program
+is operating with a single thread.  The programmer can also flush the 
+garbage list by calling sarray_remove_garbage when the programmer can
+ensure that no message dispatching is taking place concurrently.  The
+amount of un-reclaimed sarray garbage should normally be extremely
+small in a real program as sarray structures are freed only when using
+the "poseAs" functionality and early in program initialization, which
+normally occurs while the program is single threaded.

+The following variables are either statically or globally defined. This list 
+does not include variables which are internal to implementation dependent 
+versions of thread-*.c.

+******************************************************************************
+* Frontend/Backend design:
+
+The design of the Objective-C runtime thread and mutex functions utilizes a
+frontend/backend implementation.
+
+The frontend, as characterized by the files thr.h and thr.c, is a set
+of platform independent structures and functions which represent the
+user interface.  Objective-C programs should use these structures and
+functions for their thread and mutex work if they wish to maintain a
+high degree of portability across platforms.
+
+The backend is composed of a file with the necessary code to map the ObjC
+thread and mutex to a platform specific implementation.  For example, the
+file thr-solaris.c contains the implementation for Solaris.
+
+If you are compiling libobjc as part of GCC, the thr-objc.c backend is
+always used; this backend uses GCC's gthread code.  The thread system
+is automatically configured when GCC is configured.  Important: make
+sure you configure GCC using `--enable-threads' if you want threads !
+  
+If you want to compile libobjc standalone, then you would need to
+modify the configure.in and makefiles for it; and you need to pick an
+appropriate backend file for the target platform; you make this choice
+by assigning the OBJC_THREAD_FILE make variable to the basename of the
+backend file.  For example, OBJC_THREAD_FILE=thr-posix would indicate
+that the generic posix backend file, thr-posix.c, should be compiled
+with the ObjC runtime library.  If your platform does not support
+threads then you should specify the OBJC_THREAD_FILE=thr-single
+backend file to compile the ObjC runtime library without thread or
+mutex support; note that programs which rely upon the ObjC thread and
+mutex functions will compile and link correctly but attempting to
+create a thread or mutex will result in an error.
+  
+It is questionable whether it is really necessary to have both a
+frontend and backend function for all available functionality.  On the
+one hand, it provides a clear, consistent differentiation between what
+is public and what is private with the downside of having the overhead
+of multiple functions calls.  For example, the function to have a
+thread yield the processor is objc_thread_yield; in the current
+implementation this produces a function call set:
+
+objc_thread_yield()  ->  __objc_thread_yield()  ->  system yield function
+
+This has two extra function calls over calling the platform specific function
+explicitly, but the issue is whether only the overhead of a single function
+is necessary.
+
+objc_thread_yield()  ->  system yield function
+
+This breaks the public/private dichotomy between the frontend/backend
+for the sake of efficiency.  It is possible to just use a preprocessor
+define so as to eliminate the extra function call:
+
+#define objc_thread_yield() __objc_thread_yield()
+
+This has the undesirable effect that if objc_thread_yield is actually
+turned into a function based upon future need; then ObjC programs which
+access the thread functions would need to be recompiled versus just
+being relinked.
+ 
+******************************************************************************
+* Threads:
+
+The thread system attempts to create multiple threads using whatever
+operating system or library thread support is available.  It does
+assume that all system functions are thread safe.  Notably this means
+that the system implementation of malloc and free must be thread safe.
+If a system has multiple processors, the threads are configured for
+full parallel processing.
+
+* Backend initialization functions
+
+__objc_init_thread_system(void), int

+
+*****
+* Backend thread functions
+* User programs should *NOT* directly call these functions.

+******************************************************************************
+* Mutexes:
+
+Mutexes can be locked recursively.  Each locked mutex remembers
+its owner (by thread id) and how many times it has been locked.  The

+threads to access the mutex.
+
+*****
+* Frontend mutex functions

+	Locks a mutex.  As mentioned earlier, the same thread may call
+	this routine repeatedly.
+	Return -1 if error otherwise return 0.
+	
+objc_mutex_trylock(objc_mutex_t mutex), int
+	Attempts to lock a mutex.  If lock on mutex can be acquired 
+	then function operates exactly as objc_mutex_lock.
+	Return -1 if failed to acquire lock otherwise return 0.
+
+objc_mutex_unlock(objc_mutex_t mutex), int

+
+objc_condition_wait(objc_condition_t condition, objc_mutex_t mutex), int

+This readme refers to the file thr-mach.c.
+
+Under mach, thread priorities are kinda strange-- any given thread has
+a MAXIMUM priority and a BASE priority.  The BASE priority is the
+current priority of the thread and the MAXIMUM is the maximum possible
+priority the thread can assume.  The developer can lower, but never
+raise the maximum priority.
+
+The gcc concept of thread priorities is that they run at one of three
+levels;  interactive, background, and low.
+
+Under mach, this is translated to:
+
+interactive -- set priority to maximum
+background  -- set priority to 2/3 of maximum
+low         -- set priority to 1/3 of maximum
+
+This means that it is possible for a thread with the priority of
+interactive to actually run at a lower priority than another thread
+with a background, or even low, priority if the developer has modified
+the maximum priority.

+
+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+  The code in this file critically affects class method invocation
+  speed.  This long preamble comment explains why, and the issues
+  involved.  
+
+
+  One of the traditional weaknesses of the GNU Objective-C runtime is
+  that class method invocations are slow.  The reason is that when you
+  write
+  
+  array = [NSArray new];
+  
+  this gets basically compiled into the equivalent of 
+  
+  array = [(objc_get_class ("NSArray")) new];
+  
+  objc_get_class returns the class pointer corresponding to the string
+  `NSArray'; and because of the lookup, the operation is more
+  complicated and slow than a simple instance method invocation.  
+  
+  Most high performance Objective-C code (using the GNU Objc runtime)
+  I had the opportunity to read (or write) work around this problem by
+  caching the class pointer:
+  
+  Class arrayClass = [NSArray class];
+  
+  ... later on ...
+  
+  array = [arrayClass new];
+  array = [arrayClass new];
+  array = [arrayClass new];
+  
+  In this case, you always perform a class lookup (the first one), but
+  then all the [arrayClass new] methods run exactly as fast as an
+  instance method invocation.  It helps if you have many class method
+  invocations to the same class.  
+  
+  The long-term solution to this problem would be to modify the
+  compiler to output tables of class pointers corresponding to all the
+  class method invocations, and to add code to the runtime to update
+  these tables - that should in the end allow class method invocations
+  to perform precisely as fast as instance method invocations, because
+  no class lookup would be involved.  I think the Apple Objective-C
+  runtime uses this technique.  Doing this involves synchronized
+  modifications in the runtime and in the compiler.  
+  
+  As a first medicine to the problem, I [NP] have redesigned and
+  rewritten the way the runtime is performing class lookup.  This
+  doesn't give as much speed as the other (definitive) approach, but
+  at least a class method invocation now takes approximately 4.5 times
+  an instance method invocation on my machine (it would take approx 12
+  times before the rewriting), which is a lot better.  
+
+  One of the main reason the new class lookup is so faster is because
+  I implemented it in a way that can safely run multithreaded without
+  using locks - a so-called `lock-free' data structure.  The atomic
+  operation is pointer assignment.  The reason why in this problem
+  lock-free data structures work so well is that you never remove
+  classes from the table - and the difficult thing with lock-free data
+  structures is freeing data when is removed from the structures.  */
