| | | | | | | | | | | | | | | | | | | | | | | | | | | Revert commit 22b615a96593 from llvm git (by Daniel Kiss): [libunwind] Support for leaf function unwinding. Unwinding leaf function is useful in cases when the backtrace finds a leaf function for example when it caused a signal. This patch also add the support for the DW_CFA_undefined because it marks the end of the frames. Ryan Prichard provided code for the tests. Reviewed By: #libunwind, mstorsjo Differential Revision: https://reviews.llvm.org/D83573 Reland with limit the test to the x86_64-linux target. Bisection has shown that this particular upstream commit causes programs using backtrace(3) on aarch64 to segfault. This affects the lang/rust port, for instance. Until we can upstream to fix this problem, revert the commit for now. Reported by: mikael PR: 256864

| | | | | | | | | | | | | | | | | | | | resolution for <https://bugs.llvm.org/show_bug.cgi?id=47181>. The cache implementation depends on dl_iterate_phdr(3) ensuring that its callbacks are not called simultaneously for multiple threads, but that is only the case for the dl_iterate_phdr() implementation in rtld. In a statically linked executable, libc's dl_iterate_phdr() is used, which does no such locking. If multiple threads then call into the unwinder at the same time, it is possible to trigger a segfault. In particular, the statically linked lld which is built during the cross-tools stage can segfault in this way, because it starts multiple worker threads that can exit in parallel. Since our pthread_exit(3) invokes the unwinder, it will therefore call into it in parallel too. Notes: svn path=/projects/clang1100-import/; revision=364263

| | | | | | | | | | | | | | | | | | | | | | Fix llvm-libunwind userspace build on ARM GCC's libgcc exports a few ARM-specific symbols for ARM EABI, AEABI, or EHABI or whatever it's called. Export the same ones from LLVM-libunwind's libgcc_s, on ARM. As part of this, convert libgcc_s from a direct Version.map to one constructed from component Symbol.map files. This allows the ARM-specific Symbol.map to be included only on ARM. Fix ARM-only oddities in struct name/aliases in LLVM-libunwind to match non-ARM definitions and ARM-specific expectations in libcxxrt / libcompiler_rt. No functional change intended for non-ARM architectures. This commit does not actually flip the switch for ARM defaults from libgcc to llvm-libunwind, but makes it possible (to compile, anyway).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libunwind: make __{de,}register_frame compatible with libgcc API The libgcc __register_frame and __deregister_frame functions take a pointer to a set of FDE/CIEs, terminated by an entry where length is 0. In Apple's libunwind implementation the pointer is taken to be to a single FDE. I suspect this was just an Apple bug, compensated by Apple- specific code in LLVM. See lib/ExecutionEngine/RuntimeDyld/RTDyldMemoryManager.cpp and http://lists.llvm.org/pipermail/llvm-dev/2013-April/061737.html for more detail. This change is based on the LLVM RTDyldMemoryManager.cpp. It should later be changed to be alignment-safe.

This uses the new layout of the upstream repository, which was recently migrated to GitHub, and converted into a "monorepo". That is, most of the earlier separate sub-projects with their own branches and tags were consolidated into one top-level directory, and are now branched and tagged together. Updating the vendor area to match this layout is next. Notes: svn path=/head/; revision=355940
