[Plugins] Load pass plugins after parsing the command line (#226773)
opt and llc load -load-pass-plugin plugins from a cl::opt callback while
parsing argv, so that the options a plugin registers are recognized
later on the command line. cl::callback is to be removed to enable
migration to a TableGen-based option representation
(https://discourse.llvm.org/t/rfc-declare-library-command-line-options-in-tablegen-one-struct-per-library/91877/5).
Load plugins after cl::ParseCommandLineOptions. A loaded plugin's
options are no longer accepted as ordinary options; pass them with
-plugin-arg=<plugin>,<arg> instead. Prefix each Polly option in Polly
tests with -plugin-arg=Polly, and each IRTransforms example option with
-plugin-arg=SimplifyCFG,.

[RISCV] Model interleave2 and deinterleave2 costs with Zvzip (#225752)
This PR extends the RISC-V TTI cost model to recognize
`llvm.vector.interleave2` and `llvm.vector.deinterleave2` when the Zvzip
extension is available.
The cost is computed based on the operand that holds the interleaved
data: the destination operand of `vzip.vv`, and the source operand of
`unzipe.v` or `unzipo.v`.
This is the first PR split out from #224991.

sysutils/pflogsumm: update to v1.2.0
After a long hiatus, pflogsumm is now getting more active development.
While here, improve Makefile handling of, for example, interpreter
substitution, etc. Note the new location for upstream.
ChangeLog for pflogsumm [since v1.1.5]
rel-1.2.0 20260422
This release promotes 1.1.15 from Beta to Production status; no code
changes have been made since that version.
The changes since 1.1.6, the last Production release, are substantive,
including:
- Config-file support
- Enhanced TLS reporting
- Improved parsing accuracy

[InstCombine] Fold `-X / -Y` to `X / Y` when it cannot overflow (#224025)
Fold:
```
(-X) / (-Y) -> X / Y
```
Do not combine when X may be INT_MIN and Y may be -1, as the result
could introduce signed division overflow.

[lld][AArch64] Support R_AARCH64_TLSLE_ADD_TPREL_LO12 (#227173)
AArch64 local-exec TLS code sequences compiled with -mtls-size=12 use
the non-NC R_AARCH64_TLSLE_ADD_TPREL_LO12 relocation (emitted for 'add
xN, xN, :tprel_lo12:sym'), but lld only handles the _NC variant, so
linking such objects fails with 'unknown relocation'.
Add the relocation to the TLS LE group in scanSectionImpl (R_TPREL, same
group as the other TLSLE relocations, so it is also rejected for
-shared) and resolve it like the _NC variant, but with an unsigned
12-bit range check as the non-NC form requires the full offset to fit
into the imm12 field.
[Clang][HLSL] Reject matrix layout modifiers on array typedefs (#227364)
Fixes #226251
Require row_major and column_major modifiers to apply directly to a
matrix type rather than accepting an array typedef whose element type is
a matrix.
This preserves valid declarations of arrays of annotated matrix elements
while rejecting attempts to apply a layout modifier to the array type
itself.
[runtimes] Add llvm-dis to compiler-rt test dependency (#227212)
A recent commit 9a0c255ce1ef introduced dependency on llvm-dis to
compiler-rt test instrprof-thinlto-indirect-call-promotion.cpp. This
caused error "llvm-dis: command not found" in CI testing. Fix by adding
llvm-dis to the dependency list for compiler-rt test.
[orc-rt] Flatten C addressing regression tests. NFC. (#227529)
Move the tests out of same-object/ and cross-object/ subdirectories into
addressing/, and mark tests of references to entities in other objects
with a -cross-obj suffix. This keeps the variants of a construct
together, e.g. global-function-call.c next to
global-function-call-cross-obj.test, so gaps in coverage are easier to
spot.
[SystemZ][z/OS] Emit CELQMAIN for a module defining main (#226710)
The Language Environment startup routine `CELQSTRT` finds the main
routine and its environment through `CELQMAIN`. clang does not emit it;
the driver links with `-u CELQMAIN`, which pulls the copy from
`SCEEBND2`. That copy is in NORENT format and refers to the symbol
`MAIN`, so a program built with clang does not start (U4093 reason 218,
or a protection exception because no WSA is allocated and the ADA offset
is used as an absolute address).
For a module that defines `main`, emit `CELQMAIN` in RENT format as
described in "z/OS Language Environment Vendor Interfaces", chapter
"Program initialization and termination for AMODE 64 applications", plus
a reference to the bootstrap routine `CELQBST`, which `CELQSTRT` only
references weakly. `CELQMAIN` gets OS linkage, because `CELQSTRT`,
`CELQINPL` and `CELQBST` reference it with OS linkage (otherwise the
binder reports IEW2469E).
With this change `int main(void) { return 42; }` bound with `ld -e

[libc++] Bump machines to latest test suite (#227528)
We recently merged some fixes for the test suite which should make the
comparisons more meaningful. Since we haven't re-generated anything
since the recent LNT machine bumps, re-bumping now should not cause any
churn.
[AMDGPU] Fix inline constant for scalar_to_vector of bf16 math ops (#227479)
On targets with BF16InlineConstFromUpperFP32, an inline constant on a
packed bf16 instruction is expanded to FP32, so only a splat is
encodable and both lanes must use op_sel to read the upper half. Scalar
bf16 math lowers to V_PK_* with a dead high lane, so the constant
arrived as (scalar_to_vector bf16:c), which is not a splat yet still
looked inlinable and got folded without op_sel, reading the wrong half.
Combine (scalar_to_vector bf16:c) into a splat BUILD_VECTOR when c is an
inlinable bf16 constant on such subtargets, and in SIFoldOperands
disable the V2BF16 folding paths that would inline a literal without
op_sel. Also allow op_sel_lo on src1 in isOMod() for V_PK_MUL_BF16 so
omod folding still applies.
Fixes: LCOMPILER-2879 and ROCM-30938
[lldb] Find Python relative to LLDB.framework on Darwin (again) (#227521)
The PythonRuntimeLoaderDarwin is responsible for finding the Python
library at runtime. Previously, this was using `DEVELOPER_DIR` and
`xcrun` to avoid having to hard-code the same list of relative paths
that we have as RPATHs for the non-dynamic interpreter build.
However, that leads to some tricky behavior when launching `lldb` with
our without `xcrun`. Combined with some odd path combinations, I changed
my mind and went back to mimicking the RPATH approach.
While I was at it, I also dropped the fallback for looking for Python in
/Applications/Xcode.app. That was always a hack, and now that we support
falling back to a Homebrew or Pyhthon.org installed Python.framework, I
think we should just rely on that.

[libc++][docs] Convert documentation from reST to Markdown (batch 2) (#222064)
This is the second batch of changes to migrate libc++ documentation from
rst to markdown.
I use a local pixel diff tool to compare the rendered HTML, and all
diffs seem like fixes. They tend to fall into the following categories:
- dashed bullet lists were previously not rendered, but now they are
- extra indentation interpreted as blockquotes has been removed
- single backticks are now codefont spans, not italic spans

[orc-rt] Add C addressing regression tests for functions. (#227518)
Add tests that check that JIT'd C code can call functions, both in the
same object and in other objects: direct calls, calls through function
pointers stored in initialized data, and tail calls. The tail call tests
only run at -O2, since an unoptimized build may not emit tail calls.
