+Subject: [PATCH] [CGP] Bail out if (Base|Scaled)Reg does not dominate insert
+ point. (#142949)
+
+(Base|Scaled)Reg may not dominate the chosen insert point, if there are
+multiple uses of the address. Bail out if that's the case, otherwise we
+will generate invalid IR.
+
+In some cases, we could probably adjust the insert point or hoist the
+(Base|Scaled)Reg.

+Subject: [PATCH] [CodeGenPrepare] Make sure instruction get from SunkAddrs is
+ before MemoryInst (#139303)
+
+Function optimizeBlock may do optimizations on a block for multiple
+times. In the first iteration of the loop, MemoryInst1 may generate a
+sunk instruction and store it into SunkAddrs. In the second iteration of
+the loop, MemoryInst2 may use the same address and then it can reuse the
+sunk instruction stored in SunkAddrs, but MemoryInst2 may be before
+MemoryInst1 and the corresponding sunk instruction. In order to avoid
+use before def error, we need to find appropriate insert position for the
+ sunk instruction.
+
+Fixes #138208.

-Subject: [PATCH] [LLD][AArch64] Make adrp+ldr relaxation per-symbol
- all-or-nothing (#208396)
-
-We can't relax only some adrp+ldr pairs for a symbol, because there may
-be a branch target between the adrp and ldr of this form:
-
-        adrp    x1, :got:sym
-    .Lfoo:
-        ldr     x1, [x1, :got_lo12:sym]
-        # ...
-
-        adrp    x1, :got:sym
-        ldr     x2, [x1, :got_lo12:sym]
-        b       .Lfoo
-
-Relaxing the first adrp+ldr here would be invalid. This was clarified in
-the ARM ABI in:
-https://github.com/ARM-software/abi-aa/commit/11fb4ef42898060189d6a34ee96966e696ecbd20.
-
-The implementation already performed a pre-scan to check that the
-relevant relocations occur in pairs. Change this scan to a) check all
-the preconditions for the relaxation and b) make the decision per
-symbol.
-
-Fixes https://github.com/llvm/llvm-project/issues/138254.

-Subject: [PATCH] [LLVM][Verifier] Fix buffer overflow when verifying
- gc.statepoint (#208278)
-
-When a negative base index is passed, the verification detects the
-out-of-bounds value and start printing information that helps to
-identify what caused the error. In order to print all the information,
-it tries to dereference the Base pointer at
-GCRelocateInst::getBasePtr(), causing the buffer overflow. Add a bounds
-check to getBasePTR() and getDerivedPtr() in order to avoid this.
-
-Improve the test in order to validate negative values passed as indexes.
-They're based on the reproducer from issue #199191.
-
-Fixes #199191

+ PPC::isSplatShuffleMask query (#145149)
+
+Currently, the query assumes that a single undef byte implies the rest of
+the `EltSize - 1` bytes are undefs, but that's not always true.
+e.g. isSplatShuffleMask(
+<0,1,2,3,4,5,6,7,undef,undef,undef,undef,0,1,2,3>, 8) should return
+false.

-Subject: [PATCH] [X86] Fix EVEX compression for VPMOV*2M + KMOV with tied mask
- use (#198220)
-
-When scanning uses of the mask produced by `VPMOV*2M`, we previously bailed out as soon as we encountered a write. For tied read/write mask instructions such as `KSHIFTR*`, which both read and write the same mask register, the pass could miss the use, fold the earlier `KMOV`, and erase the `VPMOV*2M` def even though the mask was still live.
-
-Disclaimer: LLM came up with the MIR tests and explained this pass to me.
-
-Fixes #198197
-
-(cherry picked from commit f0fc9d0abf7024ceb5cb827b16f02c10e54fe0fd)

+Subject: [PATCH] [cmake] Resolve symlink when finding install prefix
+
+When determining the install prefix in LLVMConfig.cmake etc resolve
+symlinks in CMAKE_CURRENT_LIST_FILE first. The motivation for this
+is to support symlinks like `/usr/lib64/cmake/llvm` to
+`/usr/lib64/llvm19/lib/cmake/llvm`. This only works correctly if
+the paths are relative to the resolved symlink.
+
+It's worth noting that this *mostly* already works out of the box,
+because cmake automatically does the symlink resolution when the
+library is found via CMAKE_PREFIX_PATH. It just doesn't happen
+when it's found via the default prefix path.

-
-Do the same in LLD. These do not have a dedicated section type or flags,
-so this is handled by the name-based logic. (Peculiarly, there used to
-be SHF_GNU_BUILD_NOTE, but it was removed again.)
-
-Not concatenating these results in a huge number of sections, which
-breaks tools like `file`.

-Subject: [PATCH] [lit] Normalize RLIM_INFINITY to "infinity" in
- print_limits.py for Python 3.15+ (#190953)
-
-Python 3.15 changed resource.getrlimit() to return the platform's
-maximum value (e.g., 18446744073709551615 on 64-bit systems) instead of
--1 for RLIM_INFINITY. This breaks lit tests that expect -1 for unlimited
-resource limits.
-
-This patch normalizes the return value to "infinity" when it equals
-RLIM_INFINITY to maintain compatibility with existing tests across all
-Python versions.
-
-Fixes test failure: shtest-ulimit-nondarwin.py
-Expected: RLIMIT_FSIZE=-1
-Got: RLIMIT_FSIZE=18446744073709551615

+Subject: [PATCH] [PowerPC] fix lowering of SPILL_CRBIT on pwr9 and pwr10
+
+If a copy exists between creation of a crbit and a spill, machine-cp
+may delete the copy since it seems unaware of the relation between a cr
+and crbit. A fix was previously made for the generic ppc64 lowering. It
+should be applied to the pwr9 and pwr10 variants too.
+
+Likewise, relax and extend the pwr8 test to verify pwr9 and pwr10
+codegen too.
+
+This fixes #143989.
