We had too many `*.so` libraries added to the `clang-devel` package.
Before we've added these implicitly by accident:
```
/usr/lib64/libLLVM.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libLTO.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libRemarks.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libclang-cpp.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libclang.so.19.0.0pre20240509.g943617d12ccbd3
/usr/lib64/libclang.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/liblldCOFF.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/liblldCommon.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/liblldELF.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/liblldMachO.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/liblldMinGW.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/liblldWasm.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libomptarget.rtl.amdgpu.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libomptarget.rtl.cuda.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libomptarget.rtl.host.so.19.0pre20240509.g943617d12ccbd3
/usr/lib64/libomptarget.so.19.0pre20240509.g943617d12ccbd3
```
And now we're adding just these because these are the ones that used to
exist within the clang-devel package when it was still being built in
standalone mode:
```
/usr/lib64/libclang-cpp.so
/usr/lib64/libclang.so
```
The default `License:`-tag on the top-level llvm package is
`Apache-2.0 WITH LLVM-exception OR NCSA` and the default `URL:`-tag is
`http://llvm.org`.
These will be inherited by all sub-packages and so we only need to list
exceptions in the spec file.
This already happens implicitly because we don't build from a git
checkout. However, currently this also breaks the build due to
https://github.com/llvm/llvm-project/pull/88164. Avoid this by
explicitly disabling the option.
* %check: export LD_LIBRARY_PATH because runtimes use external cmake projects that wouldn't find libclang++.so
* %check: use LLVM's LIT_XFAIL to mark tests that are expected to fail and don't just delete them
* clang: bring over *.patch files
* clang: remove build requires tags from clang package that are already defined by main llvm package
* clang: remove duplicates found in llvm globals and use %{pkg_datadir} instead of %{install_datadir}
* clang: rename and use pkg_name -> pkg_name_clang
* clang: use %{pkg_name_clang} instead of %{name}
* compiler-rt and libomp: wrap in %if %{without compat_build}
* libomp: also build libomp for s390x (See https://github.com/llvm/llvm-project/pull/66081)
* libomp: exclude libomp-devel on s390x just like libomp itself
* libomp: introduce pkg_name_libomp and cleanup the globals
* libomp: remove gdb-plugin (NEED TO CONFIRM IF THIS IS REALLY TRUE)
* libomp: filter out flaky libomp test: ompt/teams/distribute_dispatch.c
* llvm: add BuildRequires: graphviz to llvm-doc
* llvm: use %{pkg_name_llvm} instead of %{name}
* make: added temporary Makefile so I can more easily run srpm or rpm builds locally
* make: Added local-tmt-vm target (not really useful yet)
* rpm: for non-RHEL add prefix like "Jan 05 16:17:06" to every log line This should help in finding out how long things take to build/install/...
* rpm: fully specify %files for top-level packages
* rpm: make all packages fully qualified
* rpm: obsolete llvm-snapshot-builder
* rpm: remove BuildRequires: python3-lit because we have it in-tree
* rpm: remove BuildRequires: tags for clang and llvm specifics as we're building in-tree
* rpm: rename %llvm_srcdir -> %srcdir_llvm
* rpm: rename %pkg_name -> %pkg_name_llvm
* rpm: use full qualified name in %description
* rpm: use region comments in spec file to group by package. This allows editors to fold text to get a better overview
* rpmlint: update rc file to reflect clang and compiler-rt (libomp has no rpmlint rc file)
* use python-lit from within tree
ld.gold is crashing with an internal error.
Disable this test temporarily while the issue is being investigated and
fixed.
