- * init.c (__objc_exec_class): Work around a bug in clang's code
- generation. Clang sets the class->info field to values different
- from 0x1 or 0x2 (the only allowed values in the traditional GNU
- Objective-C runtime ABI) to store some additional information, but

-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.
-
-******************************************************************************
-* Static Variables:
-
-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.
-
-The following threading designations are used:
- SAFE : Implicitly thread safe.
- SINGLE : Must only be used in single thread mode.
- MUTEX : Protected by single global mutex objc_runtime_mutex.
- UNUSED : Not used in the runtime.
-

-
-
-******************************************************************************
-* 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. For example, objc_mutex_lock(). 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 currently GCC's gthread code (gthr.h and related). For
-example, __gthread_objc_mutex_lock(). The thread system is
-automatically configured when GCC is configured. On most platforms
-this thread backend is able to automatically switch to non-multi-threaded
-mode if the threading library is not linked in.
-
-If you want to compile libobjc standalone, then you would need to modify
-the configure.in and makefiles for it and you need to import the
-gthread code from GCC.
-
-******************************************************************************
-* 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
- Initialize the thread subsystem. Called once by __objc_exec_class.
- Return -1 if error otherwise return 0.
-
-__objc_close_thread_system(void), int
- Closes the thread subsystem, not currently guaranteed to be called.
- Return -1 if error otherwise return 0.
-
-*****
-* Frontend thread functions
-* User programs should use these functions.
-
-objc_thread_detach(SEL selector, id object, id argument), objc_thread_t
- Creates and detaches a new thread. The new thread starts by
- sending the given selector with a single argument to the
- given object.
-
-objc_thread_set_priority(int priority), int
- Sets a thread's relative priority within the program. Valid
- options are:
-

-
-objc_thread_get_priority(void), int
- Query a thread's priority.
-
-objc_thread_yield(void), void
- Yields processor to another thread with equal or higher
- priority. It is up to the system scheduler to determine if
- the processor is taken or not.
-
-objc_thread_exit(void), int
- Terminates a thread. If this is the last thread executing
- then the program will terminate.
-
-objc_thread_id(void), int
- Returns the current thread's id.
-
-objc_thread_set_data(void *value), int
- Set a pointer to the thread's local storage. Local storage is
- thread specific.
-
-objc_thread_get_data(void), void *
- Returns the pointer to the thread's local storage.
-
-*****
-* Backend thread functions
-* User programs should *NOT* directly call these functions.
-
-__gthr_objc_thread_detach(void (*func)(void *arg), void *arg), objc_thread_t

-
-
-******************************************************************************
-* Mutexes:
-
-Mutexes can be locked recursively. Each locked mutex remembers
-its owner (by thread id) and how many times it has been locked. The
-last unlock on a mutex removes the system lock and allows other
-threads to access the mutex.
-
-*****
-* Frontend mutex functions
-* User programs should use these functions.
-
-objc_mutex_allocate(void), objc_mutex_t
- Allocates a new mutex. Mutex is initially unlocked.
- Return NULL if error otherwise return mutex pointer.
-
-objc_mutex_deallocate(objc_mutex_t mutex), int
- Free a mutex. Before freeing the mutex, makes sure that no
- one else is using it.
- Return -1 if error otherwise return 0.

- Locks a mutex. As mentioned earlier, the same thread may call
- this routine repeatedly.
- Return -1 if error otherwise return 0.

- Unlocks the mutex by one level. Other threads may not acquire
- the mutex until this thread has released all locks on it.

-objc_condition_allocate(void), objc_condition_t
- Allocate a condition mutex.
- Return NULL if error otherwise return condition pointer.
-
-objc_condition_deallocate(objc_condition_t condition), int
- Deallocate a condition. Note that this includes an implicit
- condition_broadcast to insure that waiting threads have the
- opportunity to wake. It is legal to dealloc a condition only
- if no other thread is/will be using it. Does NOT check for
- other threads waiting but just wakes them up.
- Return -1 if error otherwise return 0.
-
-objc_condition_wait(objc_condition_t condition, objc_mutex_t mutex), int
- Wait on the condition unlocking the mutex until objc_condition_signal()
- or objc_condition_broadcast() are called for the same condition. The
- given mutex *must* have the depth 1 so that it can be unlocked
- here, for someone else can lock it and signal/broadcast the condition.
- The mutex is used to lock access to the shared data that make up the
- "condition" predicate.
- Return -1 if error otherwise return 0.
-
-objc_condition_broadcast(objc_condition_t condition), int
- Wake up all threads waiting on this condition. It is recommended that
- the called would lock the same mutex as the threads in
- objc_condition_wait before changing the "condition predicate"
- and make this call and unlock it right away after this call.
- Return -1 if error otherwise return 0.
-
-objc_condition_signal(objc_condition_t condition), int
- Wake up one thread waiting on this condition.
- Return -1 if error otherwise return 0.

-# $ac_aux_dir to `$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.

-
-/* 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. */

-\`configure' configures package-unused version-unused to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE. See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']
-
-Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [$ac_default_prefix]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
- --bindir=DIR user executables [EPREFIX/bin]
- --sbindir=DIR system admin executables [EPREFIX/sbin]
- --libexecdir=DIR program executables [EPREFIX/libexec]
- --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
- --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
- --localstatedir=DIR modifiable single-machine data [PREFIX/var]

- --enable-version-specific-runtime-libs Specify that runtime libraries should be installed in a compiler-specific directory
- --enable-objc-gc enable the use of Boehm's garbage collector with
- the GNU Objective-C runtime.
- --enable-multilib build many library versions (default)
- --enable-maintainer-mode enable make rules and dependencies not useful
- (and sometimes confusing) to the casual installer
- --enable-shared[=PKGS] build shared libraries [default=yes]
- --enable-static[=PKGS] build static libraries [default=yes]
- --enable-fast-install[=PKGS]
- optimize for fast installation [default=yes]
- --disable-libtool-lock avoid locking (might break parallel builds)
- --enable-tls Use thread-local storage [default=yes]
- --enable-sjlj-exceptions
- force use of builtin_setjmp for exceptions
-
-Optional Packages:
- --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
- --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
- --with-build-libsubdir=DIR Directory where to find libraries for build system
- --with-target-subdir=SUBDIR
- configuring in a subdirectory
- --with-cross-host=HOST configuring with a cross compiler
- --with-pic try to use only PIC/non-PIC objects [default=use
- both]
- --with-gnu-ld assume the C compiler uses GNU ld [default=no]
-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- LIBS libraries to pass to the linker, e.g. -l<library>
- CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
- you have headers in a nonstandard directory <include dir>
- CPP C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to the package provider.

-/* To avoid the overhead of continuously allocating and deallocating
- locks, we implement a pool of locks. When a lock is needed for an
- object, we get a lock from the pool and associate it with the

- The lock pool need to be protected by its own lock (the

- single (global) protection lock we use a number of smaller pools,
- each with its own pool protection lock. To decide which lock pool
- to use for each object, we compute a hash from the object pointer.

- The implementation of each lock pool uses a linked list of all the
- locks in the pool (both unlocked, and locked); this works in the
- assumption that the number of locks concurrently required is very
- low. In practice, it seems that you rarely see more than a few
- locks ever concurrently required.
-
- A standard case is a thread acquiring a lock recursively, over and
- over again: for example when most methods of a class are protected
- by @synchronized(self) but they also call each other. We use
- thread-local storage to implement a cache and optimize this case.
- The cache stores locks that the thread successfully acquired,
- allowing objc_sync_enter() and objc_sync_exit() to locate a lock
- which is already held by the current thread without having to use
- any protection lock or synchronization mechanism. It can so detect
- recursive locks/unlocks, and transform them into no-ops that
- require no actual locking or synchronization mechanisms at all. */

- This is the function used by the compiler when compiling method

- so, a call to objc_msg_lookup() determines the IMP (the C function
- implementing the method) to call. Then, the function is called.
- If the method takes or returns different arguments, the compiler
- will cast 'function' to the right type before invoking it, making
- sure arguments and return value are handled correctly.
-
- objc_msg_lookup() must always return a valid function that can be
- called with the required method signature (otherwise the

- is NULL, objc_msg_lookup() returns a C function that does nothing,
- ignores all its arguments, and returns NULL (see nil_method.c). If
- 'receiver' does not respond to the selector 'op', objc_msg_lookup()
- will try to call +resolveClassMethod: or resolveInstanceMethod: as
- appropriate, and if they return YES, it will try the lookup again
- (+resolveClassMethod: and +resolveInstanceMethod: can thus install
- dynamically methods as they are requested). If
- +resolveClassMethod: or +resolveInstanceMethod: are either not
- available, or return NO, or return YES but 'receiver' still doesn't
- implement the 'selector' after calling them, the runtime returns a
- generic "forwarding" function that can be called with the required
- method signature and which can process the method invocation
- according to the forwarding API. There are two runtime hooks that
- allow Foundation libraries (such as GNUstep-Base) to return their
- own forwarding function in preference to the runtime ones. When
- that happens, the Foundation library effectively takes complete
- control of the forwarding process; any method invocation where the
- selector is not implemented by the receiver will end up calling a
- forwarding function chosen by the Foundation library. */
