+Subject: [PATCH] [CMake] Look up target subcomponents in LLVM_AVAILABLE_LIBS
+
+In an installation using the all-contained libLLVM.so, individual
+components are not available as targets, so we have to look them up in
+LLVM_AVAILABLE_LIBS just like llvm_map_components_to_libnames does it.
+Here I don't think we need the capitalized names though because we know
+the right capitalization. But I might be wrong.
+
+This is required by dragonffi, who call llvm_map_components_to_libnames
+on a list containing ${LLVM_NATIVE_ARCH}. Downstream bug report:
+https://bugzilla.opensuse.org/show_bug.cgi?id=1180748.

+Subject: [PATCH] Let clang-repl link privately against Clang components
+
+First of all, this is the convention: all other tools have their
+dependencies private. While it does not have an effect on linking
+(there is no linking against executables), it does have an effect
+on exporting: having the targets private allows installing the tools
+without the libraries in a statically linked build, or a build against
+libclang-cpp.so.

+// 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

+Subject: [PATCH] [sanitizer] Remove #include <linux/fs.h> to resolve
+ fsconfig_command/mount_attr conflict with glibc 2.36
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+It is generally not a good idea to mix usage of glibc headers and Linux UAPI
+headers (https://sourceware.org/glibc/wiki/Synchronizing_Headers). In glibc
+since 7eae6a91e9b1670330c9f15730082c91c0b1d570 (milestone: 2.36), sys/mount.h
+defines `fsconfig_command` which conflicts with linux/mount.h:
+
+    .../usr/include/linux/mount.h:95:6: error: redeclaration of ‘enum fsconfig_command’
+
+Remove #include <linux/fs.h> which pulls in linux/mount.h. Expand its 4 macros manually.
+Android sys/mount.h doesn't define BLKBSZGET and it still needs linux/fs.h.
+In the long term we should move Linux specific definitions to sanitizer_platform_limits_linux.cpp
+but this commit is easy to cherry pick into older compiler-rt releases.

+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.

+Subject: [PATCH 1/8] [MergeFunctions] Preserve symbols used
+ llvm.used/llvm.compiler.used
+
+llvm.used and llvm.compiler.used are often used with inline assembly
+that refers to a specific symbol so that the symbol is kept through to
+the linker even though there are no references to it from LLVM IR.
+
+This fixes the MergeFunctions pass to preserve references to these
+symbols in llvm.used/llvm.compiler.used so they are not deleted from the
+IR. This doesn't prevent these functions from being merged, but
+guarantees that an alias or thunk with the expected symbol name is kept
+in the IR.

+Subject: [PATCH] [SCEV] Fix isImpliedViaMerge() with values from previous
+ iteration (PR56242)
+
+When trying to prove an implied condition on a phi by proving it
+for all incoming values, we need to be careful about values coming
+from a backedge, as these may refer to a previous loop iteration.
+A variant of this issue was fixed in D101829, but the dominance
+condition used there isn't quite right: It checks that the value
+dominates the incoming block, which doesn't exclude backedges
+(values defined in a loop will usually dominate the loop latch,
+which is the incoming block of the backedge).
+
+Instead, we should be checking for domination of the phi block.
+Any values defined inside the loop will not dominate the loop
+header phi.
+
+Fixes https://github.com/llvm/llvm-project/issues/56242.

+Subject: [PATCH] [RuntimeDyld] RuntimeDyldELF: Clear GOTOffsetMap when
+ resetting GOT section.
+
+When the GOT section ID is reset, the GOTOffsetMap must also be cleared,
+otherwise spurious matches can be located when handling GOT relocations
+in subsequently-linked objects.
+
+Fixes Issue #61402 - see https://github.com/llvm/llvm-project/issues/61402.

+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.
