llvm/0001-cmake-Allow-shared-libraries-to-customize-the-soname.patch
Konrad Kleine ab194f104b merge llvm, clang, compiler-rt and libomp repos
* %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

Subject: [PATCH] cmake: Allow shared libraries to customize the soname using
LLVM_ABI_REVISION
The LLVM_ABI_REVISION variable is intended to be used for release
candidates which introduce an ABI change to a shared library. This
variable can be specified per library, so there is not one global value
for all of LLVM.
For example, if we LLVM X.0.0-rc2 introduces an ABI change for a library
compared with LLVM X.0.0-rc1, then the LLVM_ABI_REVISION number for
library will be incremented by 1.
In the main branch, LLVM_ABI_REVISION should always be 0, it is only
meant to be used in the release branch.
