-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.

-Fixes https://github.com/llvm/llvm-project/issues/142830.

-Subject: [PATCH] [PowerPC]: Add check for cast when shufflevector (#172443)
-
-The crash happens because the cast for `Mask =
-cast<ShuffleVectorSDNode>(Res)->getMask();` fails for node `t197: v16i8
-= vector_shuffle<16,17,18,19,4,5,6,7,8,9,10,11,u,u,u,u> t196, t196`.
-However, both `LHS` and `RHS` are the same node, so
-`DAG.getCommutedVectorShuffle` doesn't return a `ShuffleVectorSDNode`
-and crashes. The fix is to add a check before the cast is performed.

+Subject: [PATCH] [SystemZ] Fix ICE with i128->i64 uaddo carry chain
+
+We can only optimize a uaddo_carry via specialized instruction
+if the carry was produced by another uaddo(_carry) instruction;
+there is already a check for that.
+
+However, i128 uaddo(_carry) use a completely different mechanism;
+they indicate carry in a vector register instead of the CC flag.
+Thus, we must also check that we don't mix those two - that check
+has been missing.

-Subject: [PATCH] [SystemZ] Fix code in widening vector multiplication
- (#150836)
-
-Commit cdc7864 has an error which would wrongly fold widening
-multiplications into an even/odd widening operation.
-This PR fixes it and adds tests to check scenarios which should not be
-folded into an even/odd widening operation are actually not.

-Subject: [PATCH] [BPF] Remove unused weak symbol __bpf_trap (#166003)
-
-Nikita Popov reported an issue ([1]) where a dangling weak symbol
-__bpf_trap is in the final binary and this caused libbpf failing like
-below:
-
-  $ veristat -v ./t.o
-  Processing 't.o'...
-  libbpf: elf: skipping unrecognized data section(4) .eh_frame
-  libbpf: elf: skipping relo section(5) .rel.eh_frame for section(4) .eh_frame
-  libbpf: failed to find BTF for extern '__bpf_trap': -3
-  Failed to open './t.o': -3
-
-In llvm, the dag selection phase generates __bpf_trap in code. Later the
-UnreachableBlockElim pass removed __bpf_trap from the code, but
-__bpf_trap symbol survives in the symbol table.
-
-Having a dangling __bpf_trap weak symbol is not good for old kernels as
-seen in the above veristat failure. Although users could use compiler
-flag `-mllvm -bpf-disable-trap-unreachable` to workaround the issue,
-this patch fixed the issue by removing the dangling __bpf_trap.

-Subject: [PATCH] [BPF] Remove dead code related to __bpf_trap global var
- (#166440)
-
-In [1], the symbol __bpf_trap (macro BPF_TRAP) is removed if it is not
-used in the code. In the discussion in [1], it is found that the branch
-"if (Op.isSymbol())" is actually always false. Remove it to avoid
-confusion.

-Subject: [PATCH] [lldb] Fix typed commands not shown on the screen (#174216)
-
-The cause is that in `python3.14`, `fcntl.ioctl` now throws a buffer
-overflow error
-when the buffer is too small or too large (see
-https://github.com/python/cpython/pull/132919). This caused the Python
-interpreter to fail terminal detection and not properly echo user
-commands back to the screen.
-
-Fix by dropping the custom terminal size check entirely and using the
-built-in `sys.stdin.isatty()` instead.
-
-Fixes #173302
