- 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.
