llvm15/CMake-Look-up-target-subcomponents-in-LLVM_AVAILABLE_LIBS.patch
Richard Biener 43f9d469ce Accepting request 1002539 from home:aaronpuchert:llvm-next 
- 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!

Subject: [PATCH] [CMake] Look up target subcomponents in LLVM_AVAILABLE_LIBS
In an installation using the all-contained libLLVM.so, individual
components are not available as targets, so we have to look them up in
LLVM_AVAILABLE_LIBS just like llvm_map_components_to_libnames does it.
Here I don't think we need the capitalized names though because we know
the right capitalization. But I might be wrong.
This is required by dragonffi, who call llvm_map_components_to_libnames
on a list containing ${LLVM_NATIVE_ARCH}. Downstream bug report:
https://bugzilla.opensuse.org/show_bug.cgi?id=1180748.
