- Update to version 12.0.0.
* For details, see the release notes:
- https://releases.llvm.org/12.0.0/docs/ReleaseNotes.html
- https://releases.llvm.org/12.0.0/tools/clang/docs/ReleaseNotes.html
- https://releases.llvm.org/12.0.0/tools/clang/tools/extra/docs/ReleaseNotes.html
- https://releases.llvm.org/12.0.0/projects/libcxx/docs/ReleaseNotes.html
- https://releases.llvm.org/12.0.0/tools/lld/docs/ReleaseNotes.html
- Rebase patches:
* assume-opensuse.patch
* lldb-cmake.patch
* llvm-better-detect-64bit-atomics-support.patch
* llvm-do-not-install-static-libraries.patch
* llvm_build_tablegen_component_as_shared_library.patch
- Drop patches that have landed upstream:
* Fix-missing-include.patch
- Always use ld.bfd for stage 1, use lld for stage 2 where we use
ThinLTO and where it's supported, gold where lld doesn't work,
and ld.bfd where we don't use ThinLTO. (boo#1181621)
- Add lld-no-version-on-undefined-weak-lazy-symbols.patch to fix a
bug in lld that made libLLVM.so contain a corrupt symbol version.
- Add clangd-cmake-non-standard-layout.patch to fix build in our
non-monorepo layout.
