it on untested platforms.
- Integrated initial GNU HURD port. (Thanks to Chris Lingard and Igor
Khavkine.)
- - A few more fixes for Digital Mars compiler.
+ - A few more fixes for Digital Mars compiler (Walter Bright).
- Fixed gcc version recognition. Renamed OPERATOR_NEW_ARRAY to
GC_OPERATOR_NEW_ARRAY. Changed GC_OPERATOR_NEW_ARRAY to be the default.
It can be overridden with -DGC_NO_OPERATOR_NEW_ARRAY. (Thanks to
- Fixed a stack clearing problem that resulted in SIGILL with a
misaligned stack pointer for multithreaded SPARC builds.
- Integrated another HURD patch (thanks to Igor Khavkine).
+
+Since 6.0:
+ - Non-debug, atomic allocations could result in bogus smashed object
+ reports with debugging on. (Thanks to Patrick Doyle for the small
+ test case.)
+ - Fixed GC_get_register_stack_base (Itanium only) to work around a glibc
+ 2.2.4 bug.
+ - Initial port to HP/UX on Itanium. Thread support and both 32 and 64
+ bit ABIs appear to work. Parallel mark support doesn't yet, due to
+ some inline assembly code issues. Thread local allocation does appear
+ to work.
+ - ifdef'ed out glibc2.1/Itanium workaround. I suspect nobody is using
+ that combination anymore.
+ - Added a patch to make new_gc_alloc.h usable with gcc3.0. (Thanks to
+ Dimitris Vyzovitis for the patch.)
+ - Debugged 64-bit support on HP/UX PA-RISC.
+ - Turned on dynamic loading support for FreeBSD/ELF. (Thanks to Peter
+ Housel.)
+ - Unregistering of finalizers with debugging allocation was broken.
+ (Thanks to Jani Kajala for the test case.)
+ - Old finalizers were not returned correctly from GC_debug_register_finalizer.
+ - Disabled MPROTECT_VDB for Linux/M68K based on a report that it doesn't work.
+ - Cleaned up some statistics gathering code in reclaim.c (Thanks to Walter
+ Bright.)
+ - Added some support for OpenBSD/ELF/Linux. (Thanks to Suzuki Toshiya.)
+ - Added Jakub Jelinek's patch to use dl_iterate_phdr for dynamic library
+ traversal to dyn_load.c. Changed it to weakly reference dl_iterate_phdr,
+ so that the old code is stilll used with old versions of glibc.
+ - Cleaned up feature test macros for various threads packages and
+ integrated (partially functional) FreeBSD threads code from Loren Rittle.
+ It's likely that the cleanup broke something, since it touched lots of
+ code. It's also likelly that it fixed some unreported bugs in the
+ less common thread implementations, since some of the original code
+ didn't stand up to close scrutiny. Support for the next pthreads
+ implementation should be easier to add.
To do:
- There seem to be outstanding issues on Solaris/X86, possibly with
finding the data segment starting address. Information/patches would
- ne appreciated.
- - New_gc_alloc.h is apparently no longer compatible with the latest C++
- standard library in gcc3.0. (This isn't technically a bug, since it only
- claimed compatibility with the SGI STL. But we may need a new C++ STL
- allocator interface.)
+ be appreciated.
- Very large root set sizes (> 16 MB or so) could cause the collector
to abort with an unexpected mark stack overflow. (Thanks again to
Peter Chubb.) NOT YET FIXED. Workaround is to increase the initial
OSDN Git Service
