-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.
-The current solution isn't really optimal because the signal handler must decode
-the faulting PPC machine instruction in order to find the correct heap address.
-Further, it must poke around in the register state which the kernel saved away
-in some obscure register state structure before it calls the signal handler -
-needless to say the layout of this structure is no where documented.

-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
-shared library. (I don't completely understand why, but -fno-common seems to
-work and doesn't mess up the garbage collector's functionality).

-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.

-Brian Alliet contributed dynamic library support for MacOSX. It could also
-use more testing.

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.
+
+
To do:
- - MacOSX thread support still appears to be a bit unreliable.
- 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
__declspec(dllexport) needs to be added to declarations
to support the case in which the collector is in a dll.
-GC_DLL User-settable macro that forces the effect of _DLL.
+GC_DLL User-settable macro that forces the effect of _DLL. Set
+ by gc.h if _DLL is defined and GC_NOT_DLL is undefined.
+ This is the macro that is tested internally to determine
+ whether the GC is in its own dynamic library. May need
+ to be set by clients before including gc.h. Note that
+ inside the GC implementation it indicates that the
+ collector is in its own dynamic library, should export
+ its symbols, etc. But in clients it indicates that the

+ be referenced accordingly, and precautions may need to
+ be taken to properly deal with statically allocated
+ variables in the main program. Used only for MS Windows.
GC_NOT_DLL User-settable macro that overrides _DLL, e.g. if dynamic
libraries are used, but the collector is in a static library.
All programs using gc should be compiled with 4-byte alignment.
