- Fixed Linux USE_PROC_FOR_LIBRARIES to work with a 64-bit /proc format.
+Since 6.1:
+ - Guard the test for GC_DUMP_REGULARLY in misc.c with
+ "#ifndef NO_DEBUGGING". Otherwise it fails to build with NO_DEBUGGING
+ defined. (Thanks to Manuel Serrano.)
+ - Message about retrying suspend signals was incorrectly generated even when
+ flag was not set.
+ - Cleaned up MACOSX/NEXT root registration code. There was apparently a

+ - Removed MPROTECT_VDB for MACOSX port, based on one negative report.
+ - Arrange for gc.h and friends to be correctly installed with GNU-style
+ "make install".
+ - Enable the GNU-style build facility include C++ support in the library
+ with --enable-cplusplus. (Thanks to Thomas Maier for some of the patch.)
+ - Mark from GC_thread_key in linux_threads.c, in case that's allocated
+ from the garbage collected heap, as it is with our own thread-specific
+ storage implementation. (Thanks to Jeff Sturm.)
+ - Mark all free list header blocks if they are heap allocated. This avoids
+ some unnecessary tracing. And it remains correct if we clear the
+ root set. (Thanks to Jeff Sturm for identifying the bug.)
+ - Improved S390/Linux support. Add S390/Linux 64-bit support. (Thanks
+ to Ulrich Weigand.)
+ - Corrected the spelling of GC_{M,C}ALLOC_EXPLICTLY_TYPED to
+ GC_{M,C}ALLOC_EXPLICITLY_TYPED in gc_typed.h. This is technically
+ an interface change. Based on the fact that nobody reported this,
+ I suspect/hope there were no clients.
+ - Cleaned up gc_typed.h so that (1) it adds an extern "C" declaration
+ when appropriate, (2) doesn't generate references to undefined internal
+ macros, and (3) allows easier manual construction of descriptors.
+ - Close the file descriptor used by GC_print_address_map().
+ - Set the "close-on-exec" bit for various file descriptors maintained
+ for the collector's internal use.
+ - Added a hack to find memory segments owned by the system allocator
+ under win32. Based on my tests, this tends to eventually find all
+ segments, though it may take a while. There appear to be cleaner,
+ but slower solutions under NT/XP. But they rely on an API that's
+ unsupported under 9X.
+ - Changed Linux PowerPC stack finding to LINUX_STACKBOTTOM. (Thanks
+ to Akira Tagoh for pointing out that HEURISTIC1 doesn't work on
+ 64-bit kernels.)
+ - Added GC_set_free_space_divisor to avoid some Windows dll issues.
+ - Added FIXUP_POINTER, POINTER_SHIFT, POINTER_MASK to allow preprocessing
+ of candidate pointers for tagging, etc.
+ - Always lock around GC_notify_full_gc(). Simplified code for
+ invoking GC_notify_full_gc().
+ - Changed the way DATASTART is defined on FreeBSD to be robust against
+ an unmapped page after etext. (Thanks to Hironori Sakamoto for
+ tracking down the intermittent failure.)
+ - Made GC_enable() and GC_disable() official. Deprecated direct update
+ of GC_dont_gc. Changed GC_gcollect to be a noop when garbage collection
+ is disabled.
+ - Call GC_register_dynamic_libraries before stopping the world on Linux,
+ in order to avoid a potential deadlock due to the dl_iterate_phdr lock.
+ - Introduced a more general mechanism for platform-dependent code to
+ decide whether the main data segment should be handled separately
+ from dynamic libraries, or registered by GC_register_dynamic_libraries.
+ The latter is more reliable and easier on Linux with dl_iterate_phdr.
+
+Since 6.2alpha1:
+ - Fixed the completely broken FreeBSD code in 6.2alpha1. (Thanks to
+ Hironori Sakamoto for the patch.)
+ - Changed IRIX reference in dbg_mlc.c to IRIX5. (Thanks to Marcus Herbert.)
+ - Attempted to work around the problems with .S filenames and the SGI
+ compiler. (Reported by several people. Untested.)
+ - Worked around an HP/UX make issue with the GNU-style build process.
+ - Fixed the --enable-cplusplus build machinery to allow builds without
+ a C++ compiler. (That was always the intent ...)
+ - Changed the debugging allocation macros to explicitly pass the return
+ address for Linux and XXXBSD on hardware for which we can't get stack
+ traces. Use __builtin_return_address(0) to generate it when possible.
+ Some of the configuration work was cleaned up (good) and moved to gc.h
+ (bad, but necessary). This should make leak detection more useful
+ on a number of platforms. (Thanks to Fabian Thylman for the suggestion.)
+ - Fixed compilation problems in dbg_mlc.c with GC_ADD_CALLER.
+ - Bumped revision number for dynamic library.
+
+Since 6.2alpha2:
+ - Don't include execinfo.h in os_dep.c when it's not needed, and may not exist.
+
+Since 6.2alpha3:
+ - Use LINUX_STACKBOTTOM for >= glibc2.2 on Linux/MIPS. (See Debian bug
+ # 177204)
+ - Integrated Jeff Sturm and Jesse Rosenstock's MACOSX threads patches.
+ - Integrated Grzegorz Jakacki's substantial GNU build patch. "Make dist"
+ should now work for the GNU build process. Documentation files
+ are installed under share/gc.
+ - Tweaked gc_cpp.h to again support the Borland compiler. (Thanks to
+ Rene Girard for pointing out the problems.)
+ - Updated BCC_MAKEFILE (thanks to Rene Girard).
+ - Added GC_ASSERT check for minimum thread stack size.
+ - Added --enable-gc-assertions.
+ - Added some web documentation to the distribution. Updated it in the
+ process.
+ - Separate gc_conf_macros.h from gc.h.
+ - Added generic GC_THREADS client-defined macro to set the appropriate
+ GC_XXX_THREADS internal macro. (gc_config_macros.h.)
+ - Add debugging versions of _ignore_off_page allocation primitves.
+ - Moved declarations of GC_make_closure and GC_debug_invoke_finalizer
+ from gc.h to gc_priv.h.
+ - Reset GC_fail_count even if only a small allocation succeeds.
+ - Integrated Brian Alliet's patch for dynamic library support on Darwin.
+ - gc_cpp.h's gc_cleanup destructor called GC_REGISTER_FINALIZER_IGNORE_SELF
+ when it should have called the lower case version, since it was
+ explicitly computing a base pointer.
+
+Since 6.2alpha4:
+ - GC_invoke_finalizers could, under rare conditions, set
+ GC_finalizer_mem_freed to an essentially random value. This could
+ possibly cause unbounded heap growth for long-running applications
+ under some conditions. (The bug was introduced in 6.1alpha5, and
+ is not in gcc3.3. Thanks to Ben Hutchings for finding it.)
+ - Attempted to sanitize the various DLL macros. GC_USE_DLL disappeared.
+ GC_DLL is used instead. All internal tests are now on GC_DLL.
+ README.macros is now more precise about the intended meaning.
+ - Include DllMain in the multithreaded win32 version only if the
+ collector is actually built as a dll. (Thanks to Mohan Embar for
+ a version of the patch.)
+ - Hide the cygwin threadAttach/Detach functions. They were violating our
+ namespace rules.
+ - Fixed an assertion in GC_check_heap_proc. Added GC_STATIC_ASSERT.
+ (Thanks again to Ben Hutchings.)
+ - Removed some obsolete definitions for Linux/PowerPC in gcconfig.h.
+ - CORD_cat was not rebalancing unbalanced trees in some cases, violating
+ a CORD invariant. Also tweaked the rebalancing rule for
+ CORD_cat_char_star. (Thanks to Alexandr Petrosian for the bug report
+ and patch.)
+ - Added hand-coded structured exception handling support to mark.c.
+ This should enable support of dynamic libraries under win32 with
+ gcc-compiled code. (Thanks to Ranjit Mathew for the patch.)
+ Turned on dynamic library scanning for win32/gcc.
+ - Removed some remnants of read wrapping. (Thanks to Kenneth Schalk.)
+ GC_USE_LD_WRAP ws probably broken in recent versions.
+ - The build could fail on some platforms since gcconfig.h could include
+ declarations mentioning ptr_t, which was not defined, e.g. when if_mach
+ was built. (Thanks to Yann Dirson for pointing this out.) Also
+ cleaned up tests for GC_PRIVATE_H in gcconfig.h a bit.
+ - The GC_LOOP_ON_ABORT environment variable interfered with incremental
+ collection, since the write fault handler was erroneously overridden.
+ Handlers are now set up in the correct order.
+ - It used to be possible to call GC_mark_thread_local_free_lists() while
+ the world was not stopped during an incremental GC. This was not safe.
+ Fortunately, it was also unnecessary. Added GC_world_stopped flag
+ to avoid it. (This caused occasional crashes in GC_set_fl_marks
+ with thread local allocation and incremental GC. This probably happened
+ primarily on old, slow multiprocessors.)
+ - Allowed overriding of MAX_THREADS in win32_threads.c from the build
+ command line. (Patch from Yannis Bres.)
+ - Taught the IA64/linux code to determine the register backing store base from
+ /proc/self/maps after checking the __libc symbol, but before guessing.
+ (__libc symbols are on the endangered list, and the guess is likely to not
+ always be right for 2.6 kernels.) Restructured the code to read and parse
+ /proc/self/maps so it only exists in one place (all platforms).
+ - The -DUSE_PROC_FOR_LIBRARIES code was broken on Linux. It claimed that it
+ also registered the main data segment, but didn't actually do so. (I don't
+ think anyone actually uses this configuration, but ...)
+ - Made another attempt to get --enablecplusplus to do the right thing.
+ Since there are unavoidable problems with C programs linking against a
+ dynamic library that includes C++ code, I separated out the c++ code into
+ libgccpp.
+
+Since 6.2alpha5:
+ - There was extra underscore in the name of GC_save_registers_in_stack
+ for NetBSD/SPARC. (Thanks to Jaap Boender for the patch.)
+ - Integrated Brian Alliet's patch for Darwin. This restructured the
+ linuxthreads/pthreads support to separate generic pthreads support
+ from more the system-dependent thread-stopping code. I believe this
+ should make it easier to eliminate the code duplication between
+ pthreads platforms in the future. The patch included some other
+ code cleanups.
+ - Integrated Dan Bonachea's patch to support AIX threads. This required
+ substantial manual integration, mostly due to conflicts with other
+ recent threads changes. It may take another iteration to
+ get it to work.
+ - Removed HPUX/PA-RISC support from aix_irix_threads.c. It wasn't used
+ anyway and it cluttered up the code. And anything we can do to migrate
+ towards generic pthreads support is a good thing.
+ - Added a more explicit test for tracing of function arguments to test.c.
+ (Thanks to Dan Grayson.)
+ - Added Akira Tagoh's PowerPC64 patch.
+ - Fixed some bit rot in the Cygwin port. (Thanks to Dan Bonachea for
+ pointing it out.) Gc.h now includes just windows.h, not winbase.h.
+ - Declared GC_save_regs_in_stack() in gc_priv.h. Remove other declarations.
+ - Changed --enable-cplusplus to use automake consitionals. The old way
+ confused libtool. "Make install" didn't work correctly for the old version.
+ Previously --enable-cplusplus was broken on cygwin.
+ - Changed the C version of GC_push_regs to fail at compile time if it is
+ generated with an empty body. This seems to have been the cause of one
+ or two subtle failures on unusual platforms. Those failures should
+ now occur at build time and be easily fixable.
+
+Since 6.2alpha6:
+ - Integrated a second round of Irix/AIX patches from Dan Bonachea.
+ Renamed mips_sgi_mach_dep.S back to mips_sgi_mach_dep.s, since it requires
+ the Irix assembler to do the C preprocessing; gcc -E doesn't work.
+ - Fixed Makefile.direct for DARWIN. (Thanks to Manuel Serrano.)
+ - There was a race between GC_pthread_detach and thread exit that could
+ result in a thread structure being deallocated by GC_pthread_detach
+ eventhough it was still needed by the thread exit code. (Thanks to
+ Dick Porter for the small test case that allowed this to be debugged.)
+ - Fixed version parsing for non-alpha versions in acinclude.m4 and
+ version checking in version.h.
+
+
To do:
+ - A dynamic libgc.so references dlopen unconditionally, but doesn't link
+ against libdl.
+ - GC_proc_fd for Solaris is not correctly updated in response to a
+ fork() call. Thus incremental collection in the child won't work
+ correctly. (Thanks to Ben Cottrell for pointing this out.)
- --enable-redirect-malloc is mostly untested and known not to work
on some platforms.
- - The win32 collector ends up tracing some (most?) objects allocated with
- the system allocator, in spite if the fact that it tries not to.
- This costs time and space, though it remains correct.
- We need a way to identify memory regions used by the system malloc(),
- or an alternate way to locate dll data areas. A very partial
- workaround is to use GC_malloc_atomic_uncollectable() instead of
- the system malloc() for most allocation.
- There seem to be outstanding issues on Solaris/X86, possibly with
finding the data segment starting address. Information/patches would
be appreciated.

+Darwin/MacOSX Support - May 20, 2003
+====================================
+
+Important Usage Notes
+=====================
+
+GC_init() MUST be called before calling any other GC functions. This
+is necessary to properly register segments in dynamic libraries. This
+call is required even if you code does not use dynamic libraries as the
+dyld code handles registering all data segments.
+
+The incremental collector is still a bit flaky on darwin. It seems to
+work reliably with workarounds for a few possible bugs in place however
+these workaround may not work correctly in all cases. There may also
+be additional problems that I have not found.
+
+Implementation Information
+==========================
+Darwin/MacOSX support is nearly complete. Thread support is reliable on
+Darwin 6.x (MacOSX 10.2) and there have been reports of success on older
+Darwin versions (MacOSX 10.1). Shared library support had also been
+added and the gc can be run from a shared library. There is currently only
+support for Darwin/PPC although adding x86 support should be trivial.
+
+Thread support is implemented in terms of mach thread_suspend and
+thread_resume calls. These provide a very clean interface to thread
+suspension. This implementation doesn't rely on pthread_kill so the
+code works on Darwin < 6.0 (MacOSX 10.1). All the code to stop the
+world is located in darwin_stop_world.c.
+
+The original incremental collector support unfortunatelly no longer works
+on recent Darwin versions. It also relied on some undocumented kernel
+structures. Mach, however, does have a very clean interface to exception
+handing. The current implementation uses Mach's exception handling.
+
+Much thanks goes to Andrew Stone, Dietmar Planitzer, Andrew Begel,
+Jeff Sturm, and Jesse Rosenstock for all their work on the
+Darwin/OS X port.

+Older Information (Most of this no longer applies to the current code)
+======================================================================
+
+While the GC should work on MacOS X Server, MacOS X and Darwin, I only tested
+it on MacOS X Server.
+I've added a PPC assembly version of GC_push_regs(), thus the setjmp() hack is
+no longer necessary. Incremental collection is supported via mprotect/signal.

+Note from Andrew Begel:
+
+One more fix to enable gc.a to link successfully into a shared library for
+MacOS X. You have to add -fno-common to the CFLAGS in the Makefile. MacOSX
+disallows common symbols in anything that eventually finds its way into a

+work and doesn't mess up the garbage collector's functionality).
+
+Feb 26, 2003
+
+Jeff Sturm and Jesse Rosenstock provided a patch that adds thread support.
+GC_MACOSX_THREADS should be defined in the build and in clients. Real
+dynamic library support is still missing, i.e. dynamic library data segments
+are still not scanned. Code that stores pointers to the garbage collected
+heap in statically allocated variables should not reside in a dynamic
+library. This still doesn't appear to be 100% reliable.
+
+Mar 10, 2003
+Brian Alliet contributed dynamic library support for MacOSX. It could also
+use more testing.

+<TITLE>Garbage Collector Interface</TITLE>
+</HEAD>
+<BODY>
+<H1>C Interface</h1>
+On many platforms, a single-threaded garbage collector library can be built
+to act as a plug-in malloc replacement. (Build with -DREDIRECT_MALLOC=GC_malloc
+-DIGNORE_FREE.) This is often the best way to deal with third-party libraries
+which leak or prematurely free objects. -DREDIRECT_MALLOC is intended
+primarily as an easy way to adapt old code, not for new development.
+<P>
+New code should use the interface discussed below.
+<P>
+Code must be linked against the GC library. On most UNIX platforms,
+this will be gc.a.
+<P>
+The following describes the standard C interface to the garbage collector.
+It is not a complete definition of the interface. It describes only the
+most commonly used functionality, approximately in decreasing order of
+frequency of use. The description assumes an ANSI C compiler.
+The full interface is described in
+<A HREF="http://hpl.hp.com/personal/Hans_Boehm/gc/gc_source/gch.txt">gc.h</a>
+or <TT>gc.h</tt> in the distribution.
+<P>
+Clients should include gc.h.
+<P>
+In the case of multithreaded code,
+gc.h should be included after the threads header file, and
+after defining the appropriate GC_XXXX_THREADS macro.
+(For 6.2alpha4 and later, simply defining GC_THREADS should suffice.)
+Gc.h must be included
+in files that use either GC or threads primitives, since threads primitives
+will be redefined to cooperate with the GC on many platforms.
+<DL>
+<DT> <B>void * GC_MALLOC(size_t <I>nbytes</i>)</b>
+<DD>
+Allocates and clears <I>nbytes</i> of storage.

+The resulting object will be automatically deallocated when unreferenced.
+References from objects allocated with the system malloc are usually not
+considered by the collector. (See GC_MALLOC_UNCOLLECTABLE, however.)
+GC_MALLOC is a macro which invokes GC_malloc by default or, if GC_DEBUG
+is defined before gc.h is included, a debugging version that checks
+occasionally for overwrite errors, and the like.
+<DT> <B>void * GC_MALLOC_ATOMIC(size_t <I>nbytes</i>)</b>

+Allocates <I>nbytes</i> of storage.
+Requires (amortized) time proportional to <I>nbytes</i>.
+The resulting object will be automatically deallocated when unreferenced.
+The client promises that the resulting object will never contain any pointers.
+The memory is not cleared.
+This is the preferred way to allocate strings, floating point arrays,
+bitmaps, etc.
+More precise information about pointer locations can be communicated to the
+collector using the interface in
+<A HREF="http://www.hpl.hp.com/personal/Hans_Boehm/gc/gc_source/gc_typedh.txt">gc_typed.h</a> in the distribution.
+<DT> <B>void * GC_MALLOC_UNCOLLECTABLE(size_t <I>nbytes</i>)</b>
+<DD>
+Identical to GC_MALLOC, except that the resulting object is not automatically
+deallocated. Unlike the system-provided malloc, the collector does
+scan the object for pointers to garbage-collectable memory, even if the
+block itself does not appear to be reachable. (Objects allocated in this way
+are effectively treated as roots by the collector.)
+<DT> <B> void * GC_REALLOC(void *old, size_t new_size) </b>
+<DD>
+Allocate a new object of the indicated size and copy (a prefix of) the
+old object into the new object. The old object is reused in place if
+convenient. If the original object was allocated with GC_malloc_atomic,
+the new object is subject to the same constraints. If it was allocated
+as an uncollectable object, then the new object is uncollectable, and
+the old object (if different) is deallocated.
+(Use GC_REALLOC with GC_MALLOC, etc.)
+<DT> <B> void GC_FREE(void *dead) </b>
+<DD>
+Explicitly deallocate an object. Typically not useful for small
+collectable objects. (Use GC_FREE with GC_MALLOC, etc.)
+<DT> <B> void * GC_MALLOC_IGNORE_OFF_PAGE(size_t <I>nbytes</i>) </b>
+<DD>
+<DT> <B> void * GC_MALLOC_ATOMIC_IGNORE_OFF_PAGE(size_t <I>nbytes</i>) </b>
+<DD>
+Analogous to GC_MALLOC and GC_MALLOC_ATOMIC, except that the client
+guarantees that as long
+as the resulting object is of use, a pointer is maintained to someplace
+inside the first 512 bytes of the object. This pointer should be declared
+volatile to avoid interference from compiler optimizations.
+(Other nonvolatile pointers to the object may exist as well.)
+This is the
+preferred way to allocate objects that are likely to be > 100KBytes in size.
+It greatly reduces the risk that such objects will be accidentally retained
+when they are no longer needed. Thus space usage may be significantly reduced.
+<DT> <B> void GC_gcollect(void) </b>
+<DD>
+Explicitly force a garbage collection.
+<DT> <B> void GC_enable_incremental(void) </b>
+<DD>
+Cause the garbage collector to perform a small amount of work
+every few invocations of GC_malloc or the like, instead of performing
+an entire collection at once. This is likely to increase total
+running time. It will improve response on a platform that either has
+suitable support in the garbage collector (Irix and most other Unix
+versions, win32 if the collector was suitably built) or if "stubborn"
+allocation is used (see <A HREF="http://www.hpl.hp.com/personal/Hans_Boehm/gc/gc_source/gch.txt">gc.h</a>).
+On many platforms this interacts poorly with system calls
+that write to the garbage collected heap.
+<DT> <B> GC_warn_proc GC_set_warn_proc(GC_warn_proc p) </b>

+Replace the default procedure used by the collector to print warnings.
+The collector
+may otherwise write to sterr, most commonly because GC_malloc was used
+in a situation in which GC_malloc_ignore_off_page would have been more
+appropriate. See <A HREF="http://www.hpl.hp.com/personal/Hans_Boehm/gc/gc_source/gch.txt">gc.h</a> for details.
+<DT> <B> void GC_register_finalizer(...) </b>
+<DD>
+Register a function to be called when an object becomes inaccessible.
+This is often useful as a backup method for releasing system resources
+(<I>e.g.</i> closing files) when the object referencing them becomes
+inaccessible.
+It is not an acceptable method to perform actions that must be performed
+in a timely fashion.

+See <A HREF="http://www.hpl.hp.com/personal/Hans_Boehm/gc/finalization.html">here</a> for a more detailed discussion

+Note that an object may become inaccessible before client code is done
+operating on its fields. Suitable synchronization is usually required.

+<H1>C++ Interface</h1>
+There are three distinct ways to use the collector from C++:
+<DL>
+<DT> <B> STL allocators </b>
+<DD>
+Users of the <A HREF="http://www.sgi.com/tech/stl">SGI extended STL</a>
+can include <TT>new_gc_alloc.h</tt> before including
+STL header files.
+(<TT>gc_alloc.h</tt> corresponds to now obsolete versions of the
+SGI STL.)
+This defines SGI-style allocators
+<UL>
+<LI> alloc
+<LI> single_client_alloc
+<LI> gc_alloc
+<LI> single_client_gc_alloc
+</ul>
+which may be used either directly to allocate memory or to instantiate
+container templates. The first two allocate uncollectable but traced
+memory, while the second two allocate collectable memory.
+The single_client versions are not safe for concurrent access by
+multiple threads, but are faster.
+<P>
+For an example, click <A HREF="http://hpl.hp.com/personal/Hans_Boehm/gc/gc_alloc_exC.txt">here</a>.
+<P>
+Recent versions of the collector also include a more standard-conforming
+allocator implemention in <TT>gc_allocator.h</tt>. It defines
+<UL>
+<LI> traceable_allocator
+<LI> gc_allocator
+</ul>
+Again the former allocates uncollectable but traced memory.
+This should work with any fully standard-conforming C++ compiler.
+<DT> <B> Class inheritance based interface </b>
+<DD>
+Users may include gc_cpp.h and then cause members of certain classes to
+be allocated in garbage collectable memory by inheriting from class gc.
+For details see <A HREF="http://hpl.hp.com/personal/Hans_Boehm/gc/gc_source/gc_cpph.txt">gc_cpp.h</a>.
+<DT> <B> C interface </b>
+<DD>
+It is also possible to use the C interface from
+<A HREF="http://hpl.hp.com/personal/Hans_Boehm/gc/gc_source/gch.txt">gc.h</a> directly.
+On platforms which use malloc to implement ::new, it should usually be possible
+to use a version of the collector that has been compiled as a malloc
+replacement. It is also possible to replace ::new and other allocation
+functions suitably.
+<P>
+Note that user-implemented small-block allocation often works poorly with
+an underlying garbage-collected large block allocator, since the collector
+has to view all objects accessible from the user's free list as reachable.
+This is likely to cause problems if GC_malloc is used with something like
+the original HP version of STL.
+This approach works with the SGI versions of the STL only if the
+<TT>malloc_alloc</tt> allocator is used.

+allocation and garbage collection activity.
+</ol>
+Since a single lock is used for all allocation-related activity, only one
+thread can be allocating or collecting at one point. This inherently
+limits performance of multi-threaded applications on multiprocessors.
+<P>
+On most platforms, the allocator/collector lock is implemented as a
+spin lock with exponential back-off. Longer wait times are implemented
+by yielding and/or sleeping. If a collection is in progress, the pure
+spinning stage is skipped. This has the advantage that uncontested and
+thus most uniprocessor lock acquisitions are very cheap. It has the
+disadvantage that the application may sleep for small periods of time
+even when there is work to be done. And threads may be unnecessarily
+woken up for short periods. Nonetheless, this scheme empirically
+outperforms native queue-based mutual exclusion implementations in most
+cases, sometimes drastically so.
+<H2>Options for enhanced scalability</h2>
+Version 6.0 of the collector adds two facilities to enhance collector
+scalability on multiprocessors. As of 6.0alpha1, these are supported
+only under Linux on X86 and IA64 processors, though ports to other
+otherwise supported Pthreads platforms should be straightforward.
+They are intended to be used together.
+<UL>
+<LI>
+Building the collector with <TT>-DPARALLEL_MARK</tt> allows the collector to
+run the mark phase in parallel in multiple threads, and thus on multiple
+processors. The mark phase typically consumes the large majority of the
+collection time. Thus this largely parallelizes the garbage collector
+itself, though not the allocation process. Currently the marking is
+performed by the thread that triggered the collection, together with
+<I>N</i>-1 dedicated
+threads, where <I>N</i> is the number of processors detected by the collector.
+The dedicated threads are created once at initialization time.
+<P>
+A second effect of this flag is to switch to a more concurrent
+implementation of <TT>GC_malloc_many</tt>, so that free lists can be
+built, and memory can be cleared, by more than one thread concurrently.
+<LI>
+Building the collector with -DTHREAD_LOCAL_ALLOC adds support for thread
+local allocation. It does not, by itself, cause thread local allocation
+to be used. It simply allows the use of the interface in
+<TT>gc_local_alloc.h</tt>.
+<P>
+Memory returned from thread-local allocators is completely interchangeable
+with that returned by the standard allocators. It may be used by other
+threads. The only difference is that, if the thread allocates enough
+memory of a certain kind, it will build a thread-local free list for
+objects of that kind, and allocate from that. This greatly reduces
+locking. The thread-local free lists are refilled using
+<TT>GC_malloc_many</tt>.
+<P>
+An important side effect of this flag is to replace the default
+spin-then-sleep lock to be replace by a spin-then-queue based implementation.
+This <I>reduces performance</i> for the standard allocation functions,
+though it usually improves performance when thread-local allocation is
+used heavily, and thus the number of short-duration lock acquisitions
+is greatly reduced.
+</ul>
+<P>
+The easiest way to switch an application to thread-local allocation is to
+<OL>
+<LI> Define the macro <TT>GC_REDIRECT_TO_LOCAL</tt>,
+and then include the <TT>gc.h</tt>
+header in each client source file.
+<LI> Invoke <TT>GC_thr_init()</tt> before any allocation.
+<LI> Allocate using <TT>GC_MALLOC</tt>, <TT>GC_MALLOC_ATOMIC</tt>,
+and/or <TT>GC_GCJ_MALLOC</tt>.
+</ol>
+<H2>The Parallel Marking Algorithm</h2>
+We use an algorithm similar to
+<A HREF="http://www.yl.is.s.u-tokyo.ac.jp/gc/">that developed by
+Endo, Taura, and Yonezawa</a> at the University of Tokyo.
+However, the data structures and implementation are different,
+and represent a smaller change to the original collector source,
+probably at the expense of extreme scalability. Some of
+the refinements they suggest, <I>e.g.</i> splitting large
+objects, were also incorporated into out approach.
+<P>
+The global mark stack is transformed into a global work queue.
+Unlike the usual case, it never shrinks during a mark phase.
+The mark threads remove objects from the queue by copying them to a
+local mark stack and changing the global descriptor to zero, indicating
+that there is no more work to be done for this entry.
+This removal
+is done with no synchronization. Thus it is possible for more than
+one worker to remove the same entry, resulting in some work duplication.
+<P>
+The global work queue grows only if a marker thread decides to
+return some of its local mark stack to the global one. This
+is done if the global queue appears to be running low, or if
+the local stack is in danger of overflowing. It does require
+synchronization, but should be relatively rare.
+<P>
+The sequential marking code is reused to process local mark stacks.
+Hence the amount of additional code required for parallel marking
+is minimal.
+<P>
+It should be possible to use generational collection in the presence of the
+parallel collector, by calling <TT>GC_enable_incremental()</tt>.
+This does not result in fully incremental collection, since parallel mark
+phases cannot currently be interrupted, and doing so may be too
+expensive.
+<P>
+Gcj-style mark descriptors do not currently mix with the combination
+of local allocation and incremental collection. They should work correctly
+with one or the other, but not both.
+<P>
+The number of marker threads is set on startup to the number of
+available processors (or to the value of the <TT>GC_NPROCS</tt>
+environment variable). If only a single processor is detected,
+parallel marking is disabled.
+<P>
+Note that setting GC_NPROCS to 1 also causes some lock acquisitions inside
+the collector to immediately yield the processor instead of busy waiting
+first. In the case of a multiprocessor and a client with multiple
+simultaneously runnable threads, this may have disastrous performance
+consequences (e.g. a factor of 10 slowdown).
+<H2>Performance</h2>
+We conducted some simple experiments with a version of
+<A HREF="gc_bench.html">our GC benchmark</a> that was slightly modified to
+run multiple concurrent client threads in the same address space.
+Each client thread does the same work as the original benchmark, but they share
+a heap.
+This benchmark involves very little work outside of memory allocation.
+This was run with GC 6.0alpha3 on a dual processor Pentium III/500 machine
+under Linux 2.2.12.
+<P>
+Running with a thread-unsafe collector, the benchmark ran in 9
+seconds. With the simple thread-safe collector,
+built with <TT>-DLINUX_THREADS</tt>, the execution time
+increased to 10.3 seconds, or 23.5 elapsed seconds with two clients.
+(The times for the <TT>malloc</tt>/i<TT>free</tt> version
+with glibc <TT>malloc</tt>
+are 10.51 (standard library, pthreads not linked),
+20.90 (one thread, pthreads linked),
+and 24.55 seconds respectively. The benchmark favors a
+garbage collector, since most objects are small.)
+<P>
+The following table gives execution times for the collector built
+with parallel marking and thread-local allocation support
+(<TT>-DGC_LINUX_THREADS -DPARALLEL_MARK -DTHREAD_LOCAL_ALLOC</tt>). We tested
+the client using either one or two marker threads, and running
+one or two client threads. Note that the client uses thread local
+allocation exclusively. With -DTHREAD_LOCAL_ALLOC the collector
+switches to a locking strategy that is better tuned to less frequent
+lock acquisition. The standard allocation primitives thus peform
+slightly worse than without -DTHREAD_LOCAL_ALLOC, and should be
+avoided in time-critical code.
+<P>
+(The results using <TT>pthread_mutex_lock</tt>
+directly for allocation locking would have been worse still, at
+least for older versions of linuxthreads.
+With THREAD_LOCAL_ALLOC, we first repeatedly try to acquire the
+lock with pthread_mutex_try_lock(), busy_waiting between attempts.
+After a fixed number of attempts, we use pthread_mutex_lock().)
+<P>
+These measurements do not use incremental collection, nor was prefetching
+enabled in the marker. We used the C version of the benchmark.
+All measurements are in elapsed seconds on an unloaded machine.
+<P>
+<TABLE BORDER ALIGN="CENTER">
+<TR><TH>Number of threads</th><TH>1 marker thread (secs.)</th>
+<TH>2 marker threads (secs.)</th></tr>
+<TR><TD>1 client</td><TD ALIGN="CENTER">10.45</td><TD ALIGN="CENTER">7.85</td>
+<TR><TD>2 clients</td><TD ALIGN="CENTER">19.95</td><TD ALIGN="CENTER">12.3</td>
+</table>
+<PP>
+The execution time for the single threaded case is slightly worse than with
+simple locking. However, even the single-threaded benchmark runs faster than
+even the thread-unsafe version if a second processor is available.
+The execution time for two clients with thread local allocation time is
+only 1.4 times the sequential execution time for a single thread in a
+thread-unsafe environment, even though it involves twice the client work.
+That represents close to a
+factor of 2 improvement over the 2 client case with the old collector.
+The old collector clearly
+still suffered from some contention overhead, in spite of the fact that the
+locking scheme had been fairly well tuned.
+<P>
+Full linear speedup (i.e. the same execution time for 1 client on one
+processor as 2 clients on 2 processors)
+is probably not achievable on this kind of
+hardware even with such a small number of processors,
+since the memory system is
+a major constraint for the garbage collector,
+the processors usually share a single memory bus, and thus
+the aggregate memory bandwidth does not increase in
+proportion to the number of processors.
+<P>
+These results are likely to be very sensitive to both hardware and OS
+issues. Preliminary experiments with an older Pentium Pro machine running
+an older kernel were far less encouraging.
