llvm13/llvm_build_tablegen_component_as_shared_library.patch
Richard Biener 6b6b4b3d80 Accepting request 922852 from home:aaronpuchert:llvm-next
- Update to version 13.0.0.
  * For details, see the release notes:
    - https://releases.llvm.org/13.0.0/docs/ReleaseNotes.html
    - https://releases.llvm.org/13.0.0/tools/clang/docs/ReleaseNotes.html
    - https://releases.llvm.org/13.0.0/tools/clang/tools/extra/docs/ReleaseNotes.html
    - https://releases.llvm.org/13.0.0/projects/libcxx/docs/ReleaseNotes.html
    - https://releases.llvm.org/13.0.0/tools/lld/docs/ReleaseNotes.html
  * New LLVM tools:
    - llvm-otool: Mach-O object file displaying tool.
    - llvm-sim: LLVM IR Similarity Visualizer.
    - llvm-tapi-diff: Diff tool for tbd files.
    - llvm-windres: Tool to manipulate Windows resources.
  * llvm-elfabi was removed.
  * New Clang tools:
    - clang-repl, an interactive interpreter for C/C++.
    - intercept-build, analyze-build: the former intercepts build
      commands to build a compilation database, the latter runs
      the static analyzer over all translation units.
    - scan-build-py: Python reimplementation of scan-build.
- Rebase patches:
  * link-clang-shared.patch
  * llvm-do-not-install-static-libraries.patch
  * llvm-exegesis-link-dylib.patch
- Drop patches that have landed upstream:
  * tablegen-test-link-static.patch
- Run tests on more architectures, disable those that seem to hang.
  Don't run libcxx tests at all anymore because they take so long.
- Relax constraints so that we can build on more machines.

The LLVMTableGen component is a special case that is excluded from libLLVM and
normally is only built as static library and linked into llvm-tblgen.
We need to have it as a shared library to be available for other projects such
as ldc.
This patch makes it even more special and forces it to be build and installed
as separate shared library.
