From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- libobjc/ChangeLog | 2925 ++++ libobjc/Makefile.in | 420 + libobjc/NXConstStr.m | 41 + libobjc/Object.m | 389 +

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).

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.

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.

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. */ + +#include "objc-private/common.h" +#include "objc-private/error.h" +#include "objc/runtime.h" +#include "objc/thr.h" +#include "objc-private/module-abi-8.h" /* For CLS_ISCLASS and similar. */ +#include "objc-private/runtime.h" /* the kitchen sink */ +#include "objc-private/sarray.h" /* For sarray_put_at_safe. */ +#include /* For memset */ + +/* We use a table which maps a class name to the corresponding class + pointer.
