| * | Fix FirstDLOpenedLinkMap for case libgc not 1st dynamically linked (NetBSD)Tsugutomo Enami2014-11-021-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current GC_FirstDLOpenedLinkMap() for NetBSD calls dlinfo(RTLD_SELF, RTLD_DI_LINKMAP, &lm) to find link_map. So it will find link_map of libgc. With guile's case, libgc is link to libguile and libguile is linked to the guile command, so libgc is not the first one in the link_map chain. That is why, data section of libguile, where scm_protects exists, is not added to GC root and GC_is_visible fails. * dyn_load.c (GC_FirstDLOpenedLinkMap): Iterate over link_map (provided by dlinfo(RTLD_SELF)) to return 2nd element instead of the provided one which might not always belong to libgc (only for NETBSD and defined RTLD_DI_LINKMAP).

| * | Fix __alloc_size__ availability detection (Clang)Yusuke Suzuki2014-10-171-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since __clang_major__/__clang_minor__ etc. are vendor dependent values, we cannot implement the feature detection based on it. For example, Apple clang versioning is different from the FreeBSD clang. (At this time, Apple clang version is "6.0 (clang-600.0.51)" and __clang_major__ is 6.) Instead of this, we can use the clang feature detection macro, __has_attribute. * include/gc_config_macros.h (GC_ATTR_ALLOC_SIZE): Replace predefined __clang_major/minor__ testing with __has_attribute() one (in case of clang).

|/ | | | | | | | | | | | | | store a thread's state when compiling against the iOS 7/8 SDK. Without this patch GC_stack_range_for() crashes when running a 32-bit app on iOS 64-bit. The old code passed an arm_thread_state_t and ARM_THREAD_STATE to thread_get_state(). ARM_THREAD_STATE is the same as ARM_UNIFIED_THREAD_STATE on iOS 7/8 and thread_get_state() actually expects an arm_unified_thread_state_t. On iOS 32-bit it looks like thread_get_state() only touches the first bytes corresponding to the size of arm_thread_state_t so no crash there. On iOS 64-bit however it seems thread_get_state() writes to the full arm_unified_thread_state_t which meant it would overflow the stack allocated struct passed to it and mess up other values on the stack leading to a crash later on.

* Workaround Linux NTPL lock elision bug.Paul Bone2014-09-114-0/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glibc 2.19 on Linux x86-64 platforms includes support for lock elision, by using Intel's TSX support when it is available. Without modifying an application this converts suitable critical sections that use mutex into transactional memory critical sections. See http://lwn.net/Articles/534758/ If a problem occurs that means that transactional memory can't be used, such as a system call or buffer overflow, the pthreads implementation will catch this error and retry the critical section using a normal mutex. I noticed that since upgrading glibc that programs using Boehm GC crash, one of these crashes was an assertion that the owner field of a mutex was invalid. The assertion was generated by the pthreads implementation. I believe that there is a bug in glibc that when a mutex cannot be used safely for transactions that some series of events causes it's owner field to be set incorrectly (or cleared when it shouldn't be). I've found that I can work around this problem by having Boehm GC use an error checking mutex, which I believe doesn't use lock elision and in my testing doesn't crash. XXX: This work-around mostly works except for linking the feature detection in configure.ac to the conditional compilation in pthread_support.c as there isn't an obvious way to make it work for automake and Makefile.direct. Could I have some help updating the build system please? include/private/pthread_support.h: pthread_support.c: Define GC_setup_mark_lock() This procedure creates the lock specifying a pthread_mutexattr_t structure. This is used to disable lock elision on Linux with glibc 2.19 or greater. configure.ac: If we're using Linux then check for the gnu extensions required to identify the version of glibc at runtime. misc.c: Call GC_setup_mark_lock() when initialising the collector.
