+// For arm64 there are three modes for the compact unwind encoding:

+//    This is a standard arm64 prolog where FP/LR are immediately pushed on the
+//    stack, then SP is copied to FP. If there are any non-volatile registers
+//    saved, then are copied into the stack frame in pairs in a contiguous
+//    range right below the saved FP/LR pair.  Any subset of the five X pairs 
+//    and four D pairs can be saved, but the memory layout must be in register
+//    number order.  
+// UNWIND_ARM64_MODE_FRAMELESS:
+//    A "frameless" leaf function, where FP/LR are not saved. The return address 
+//    remains in LR throughout the function. If any non-volatile registers
+//    are saved, they must be pushed onto the stack before any stack space is
+//    allocated for local variables.  The stack sized (including any saved
+//    non-volatile registers) divided by 16 is encoded in the bits 
+//    UNWIND_ARM64_FRAMELESS_STACK_SIZE_MASK.
+// UNWIND_ARM64_MODE_DWARF:
+//    No compact unwind encoding is available.  Instead the low 24-bits of the
+//    compact encoding is the offset of the DWARF FDE in the __eh_frame section.
+//    This mode is never used in object files.  It is only generated by the 
+//    linker in final linked images which have only DWARF unwind info for a
+//    function.

+//
+//  Relocatable Object Files: __LD,__compact_unwind
+//
+////////////////////////////////////////////////////////////////////////////////
+
+//
+// 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 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.

llvm_build_tablegen_component_as_shared_library.patch

@@ -0,0 +1,71 @@
+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.

+Subject: [PATCH] Revert D118493 "Set rpath on openmp executables"
+
+This reverts commit 9b9d08111b618d74574ba03e5cc3d752ecc56f55.
+(Accepted by Jon https://reviews.llvm.org/D118493#4178250)
+
+libc++, libc++abi, libunwind, and compiler-rt don't add the extra DT_RUNPATH,
+it's strange for OpenMP to diverge.
+Some build systems want to handle DT_RUNPATH themselves (e.g.
+CMAKE_INSTALL_RPATH). Some distributions (e.g. Fedora) have policies against
+DT_RUNPATH and the default DT_RUNPATH for OpenMP is causing trouble.
+
+For users who don't want to specify rpath by themselves,
+https://clang.llvm.org/docs/UsersManual.html#configuration-files
+can be used to specify the default rpath, e.g.
+specify -frtlib-add-rpath or -Wl,-rpath in bin/clang.cfg
