- Update to version 15.0.0. * For details, see the release notes: - https://releases.llvm.org/15.0.0/docs/ReleaseNotes.html - https://releases.llvm.org/15.0.0/tools/clang/docs/ReleaseNotes.html - https://releases.llvm.org/15.0.0/tools/clang/tools/extra/docs/ReleaseNotes.html - https://releases.llvm.org/15.0.0/projects/libcxx/docs/ReleaseNotes.html - https://releases.llvm.org/15.0.0/tools/lld/docs/ReleaseNotes.html * New LLVM tools: - llvm-debuginfod: Provides debug info to remote hosts. - llvm-dwarfutil: Can copy and manipulate debug info. - llvm-remark-size-diff: Compute diff between remark files. * New Clang tools: - clang-offload-packager: Bundle multiple objects into single fat binaries including offload code. - clang-pseudo: Approximate heuristic parser for C++. - Rebase patches: * check-no-llvm-exegesis.patch * link-clang-tools-extra-shared.patch * lld-default-sha1.patch * llvm-do-not-install-static-libraries.patch * lto-disable-cache.patch - Drop patches that have landed upstream: * clang-repl-private-deps.patch * llvm-glibc-2-36.patch * llvm-scev-fix-isImpliedViaMerge.patch - Drop llvm-lifetime-for-rust.patch: this is now solved via attributes and LLVM doesn't need a hardcoded list of allocation functions anymore. - Add llvm-link-atomic.patch to fix build on ppc. - Add libcxx-test-library-path.patch to fix libc++ tests failing without RUNPATH on libc++.so. - Add libcxxabi-fix-armv7-test.patch to fix tests on armv7l. - Thanks to Andreas Schwab for most of the rebasing!

Better detect 64bit atomics support.
|
|
|
|
It appears that on i586 std::atomic<uint64_t>::load is compiled into
|
|
instruction, but std::atomic<double>::load uses __atomic_load_8. This must
|
|
be detected so the build system links it to libatomic.
