- Apply clang-shlib-symbol-versioning.patch to add symbol versions
  to libclang-cpp.so similar to libLLVM.so. This is required when
  multiple versions of the library are loaded into the same
  process. (boo#1219405, boo#1221183, boo#1233220)

- Require libffi when we build openmp for offloading.
- Update llvm18.keyring from upstream.
- Enable lldb on s390x and ppc64le (bsc#1232906).

- Split off clang shared runtime libraries into libclang_rtX, so
  that they can be used by other packages without requiring the
  entire compiler tool chain. This is still not ergonomical: the
  libraries don't sit in %{_libdir}, so an RPATH or setting
  LD_LIBRARY_PATH is required, and they don't have an SO version,
  so zypper won't know which version to is needed. (boo#1225784)
- Add minor version to Python shebangs. (boo#1212476)
- Remove shebang and executable bit where not needed.

- Update to version 18.1.8.
  * Fix a regression from the 18.1.6 release, which could result in
    compiler crashes in the PPCMergeStringPool pass when compiling
    for PowerPC targets.
  * Fixes clang-format regressions (since 18.1.1) on breaking
    before a stream insertion operator (<<) when both operands are
    string literals.
  * Fixes a clang-format regression (since 17.0.6) on formatting
    goto labels in macro definitions.
- Rebase llvm-do-not-install-static-libraries.patch.

- Update to version 18.1.6.
  * Fixes issues where LLVM is either generating the incorrect thunk
    for a function with aligned parameters or didn't correctly pass
    through the return value when StructRet was used.
  * `-Xclang -target-feature -Xclang +unaligned-scalar-mem` can be
    used to enable unaligned scalar memory accesses for CPUs that
    do not support unaligned vector accesses. `-mno-strict-align`
    will enable unaligned scalar and vector memory accesses.
  * Don't replace an aliasee with an alias that has weak linkage.
    This avoids incorrect linkage that can lead to using the wrong
    symbols during linking time.
  * Fixes build failures when compiling AVX512 code using
    `-march=native` on machines without AVX512. The problem was
    introduced in LLVM 18.1.5.
  * Fixes crash in AArch64 backend when having `true` or `false` as
    operand for `fcmp` instruction on IR level.
  * Fixes compiler crash when user specifies `-mno-evex512` with
    AVX512 features but no AVX512VL.
  * Fixes a bug that tries to do VBROADCAST_LOAD for `f16` without
    AVX2.

- Update to version 18.1.5.
  * This release contains bug-fixes for the LLVM 18.1.0 release.
    This release is API and ABI compatible with 18.1.0.

- Update to version 18.1.4.
  * Fixes an issue with Arm64EC code generation where calls to some
    intrinsics implemented in compiler-rt used the wrong name
    mangling, eventually resulting in unresolved symbol errors
    during linking.
  * Fixed an incorrect poison-generating flag preservation in
    `InstSimplify`. It will fix a miscompilation on RISCV, which
    turns the incorrect `or disjoint` into an `add`.
  * Save/restore routines for RV32E/RV64E are added to compiler-rt.
  * Fix regressions introduced in LLVM 18.1.3 in MIPS atomicrmw
    min/max codegen.
- Include module files for libc++ in libc++-devel.
- Rebase llvm-do-not-install-static-libraries.patch.

- Update to version 18.1.3.
  * Fixes ThreadSanitizer failures for glibc's LoongArch and
    certain RISC-V ports when fstat is used.
  * `transform.structured.convert_to_loops` now properly deletes
    its target op.
  * Fix a `llvm.usub.with.overflow.i128` wrong code generation
    regression that was introduced with LLVM 18.1.0.
  * MemorySanitizer on Linux can now run even when maximum-entropy
    address-space layout randomization is configured globally (as
    is becoming increasingly common). MemorySanitizer can
    automatically re-exec ASLR-off for the process if needed,
    instead of aborting.
  * Fixed a Clang 18.x regression which increased binary size and
    stack usage with `-ftrivial-auto-var-init`.
- Set directories for configuration files: /etc/clang for system-
  wide configuration and ~/.config/clang for users. For details see
  https://clang.llvm.org/docs/UsersManual.html#configuration-files.
- Use old conflicts/provides for python3-clang on Leap.
