- New release based on version 19.1.0.

* For details, see the release notes: - https://releases.llvm.org/19.1.0/docs/ReleaseNotes.html - https://releases.llvm.org/19.1.0/tools/clang/docs/ReleaseNotes.html - https://releases.llvm.org/19.1.0/tools/clang/tools/extra/docs/ReleaseNotes.html - https://releases.llvm.org/19.1.0/projects/libcxx/docs/ReleaseNotes.html - https://releases.llvm.org/19.1.0/tools/lld/docs/ReleaseNotes.html * New LLVM tool: reduce-chunk-list to help find bugs using debug counters. See the Programmer's Manual for usage. * New Clang tools: clang-installapi for Apple-related package management, clang-nvlink-wrapper as a wrapper around `nvlink`. - No longer include OpenMP offload libraries. - Rebase patches: * clang-fix-openmp-test.patch * libcxx-test-library-path.patch * llvm-do-not-install-static-libraries.patch * llvm_build_tablegen_component_as_shared_library.patch - Remove obsolete patches: * lld-default-sha1.patch because upstream switched to sha1. * llvm-remove-clang-only-flags.patch because warning flags are no longer autodetected. * openmp-dont-run-gpu-arch.patch because we're excluding the offload project for now. - Add llvm-fix-build-failure-on-ppc64le.patch to fix ppc64le build. - Require Python 3.11 on Leap because we need Python >= 3.8 now.

+// A compiler can generated compact unwind information for a function by adding
+// a "row" to the __LD,__compact_unwind section.  This section has the
+// S_ATTR_DEBUG bit set, so the section will be ignored by older linkers.
+// It is removed by the new linker, so never ends up in final executables.
+// This section is a table, initially with one row per function (that needs
+// unwind info).  The table columns and some conceptual entries are:
+//
+//     range-start               pointer to start of function/range
+//     range-length
+//     compact-unwind-encoding   32-bit encoding
+//     personality-function      or zero if no personality function
+//     lsda                      or zero if no LSDA data
+//
+// The length and encoding fields are 32-bits.  The other are all pointer sized.
+//
+// In x86_64 assembly, these entry would look like:
+//
+//     .section __LD,__compact_unwind,regular,debug
+//
+//     #compact unwind for _foo
+//     .quad    _foo
+//     .set     L1,LfooEnd-_foo
+//     .long    L1
+//     .long    0x01010001
+//     .quad    0
+//     .quad    0
+//
+//     #compact unwind for _bar
+//     .quad    _bar
+//     .set     L2,LbarEnd-_bar
+//     .long    L2
+//     .long    0x01020011
+//     .quad    __gxx_personality
+//     .quad    except_tab1
+//
+//
+// Notes: There is no need for any labels in the __compact_unwind section.
+//        The use of the .set directive is to force the evaluation of the
+//        range-length at assembly time, instead of generating relocations.
+//
+// To support future compiler optimizations where which non-volatile registers
+// are saved changes within a function (e.g. delay saving non-volatiles until
+// necessary), there can by multiple lines in the __compact_unwind table for one
+// function, each with a different (non-overlapping) range and each with
+// different compact unwind encodings that correspond to the non-volatiles
+// saved at that range of the function.
+//
+// If a particular function is so wacky that there is no compact unwind way
+// to encode it, then the compiler can emit traditional DWARF unwind info.
+// The runtime will use which ever is available.
+//
+// Runtime support for compact unwind encodings are only available on 10.6
+// and later.  So, the compiler should not generate it when targeting pre-10.6.

+Before llvm4, both major and minor version updates of llvm were regularly
+breaking API. Because of that, the libLLVM library was named in following
+format: libLLVM-${major}-${minor}.so
+
+  (https://bugs.llvm.org/show_bug.cgi?id=25059)
+  (https://reviews.llvm.org/D13841)
+
+The package containing this library was called libLLVM${major}_${minor} which
+follows our guidelines.
+
+Since llvm4, llvm decided to follow semantic versioning and only break API if
+the major version was increased. In addition they do not intend to ever have
+minor version other than 0.
+  (http://blog.llvm.org/2016/12/llvms-new-versioning-scheme.html)
+
+The package was renamed to libLLVM${major}, which no longer follows the naming
+guidelines, but since the package contained multiple libraries, it was not
+detected.
+
+Since bnc#1049703 the libLLVM${major} package contains only the
+libLLVM-${major}-${minor}.so library and no others. This triggers the
+shlib-policy-name-error check in our packaging system.
+
+Because the reasons for using the libLLVM-${major}-${minor}.so format are no
+longer valid, lets revert back to libLLVM.so.${major}.${minor}.${version}
+format. That way the package name matches our guidelines.
+
+With llvm18, the minor version is now always 1 for releases, and upstream
+decided to rename the library to libLLVM.so.${major}.${minor}, but keep the
+old name as symbolic link for backwards compatibility. That is of course
+not relevant for us.

+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.
