[RISCV][GlobalISel] Fix fptosi/fptoui from half to i64 on RV32 (#222316)
The fcvt.l[u].h patterns are RV64-only, so RV32 had no rule for
`G_FPTOSI/G_FPTOUI` with `{s64, s16}.` The magnitude of a half is at
most `65504`, so with Zfh the i32 result of `fcvt.w[u].h` never
overflows and can simply be extended to i64.
[AMDGPU] Use synthetic fixtures for generic feature validation tests (#225551)
Remove the classification test that includes the full AMDGPU target.
Real targets are validated when generating AMDGPUTargetParserDef.inc
during the build.
Extend the lightweight generic feature tests to cover inherited
classifications of backend-only features, support through member-side
implications, and unsupported generic-side implied features.
Addresses the timeout reported on #223179
[PowerPC] Restore LiveVariables run before PPCTLSDynamicCallPass (#225816)
This change is a partial revert of 7818c91f7151. Removing the explicit
LiveVariables run before PPCTLSDynamicCallPass causes a crash on ppc64le
-fPIC builds:
```
fatal error: error in backend: Use not jointly dominated by defs.
```
This change was first added in 2016 with an unresolved FIXME.
Unfortunately, the root cause still needs to be understood and
investigated, so restore this for now to fix the broken buildbots.
[CIR] Introduce the cir.sdk_version module attribute (#225953)
CIRGen records the platform SDK version on the module as a
`cir.sdk_version` string attribute, and LoweringPrepare's CUDA/HIP
registration reads it instead of `getTargetInfo().getSDKVersion()` to gate
`__cudaRegisterFatBinaryEnd`, dropping one more `ASTContext` dependency
from the post-CIRGen pipeline.
LLVM IR already records the same fact as the "SDK Version" module flag
(`Module::setSDKVersion/getSDKVersion`), so an attribute on the module
is proper.

[flang] Remove FIRBuilder dependency from optimizer support utilities (#225836)
Fix a GCC 16 build failure where FIROps.cpp.o had undefined references
to
fir::FirOpBuilder::setCommonAttributes(mlir::Operation *) const from
FirOpBuilder::notifyOperationInserted,
RewriterBase::ForwardingListener's notifyOperationInserted, and
OpBuilder::createOrFold<fir::ConvertOp>.
FIROps.cpp includes Optimizer/Support/Utils.h, which previously included
FIRBuilder.h. That exposes the inline virtual override
FirOpBuilder::notifyOperationInserted and its call to the out-of-line
setCommonAttributes implementation. Speculative devirtualization can
turn an ordinary virtual listener call into a guarded direct call and
inline that override, introducing a reference to setCommonAttributes
without an explicit use of FirOpBuilder in FIROps.cpp. This is
consistent with the reported call sites and GCC 16's expanded
speculative devirtualization.

Update to JRuby 10.1.2.0
Enable building on aarch64. Thank you to ian@ for testing a prerelease
and confirming it works.
Update jffi to 1.4.0, which uses a different prefix.
Drop a patch for an issue that was addressed upstream.
deskutils/taskwarrior: Fix i386 build and WITH_DEBUG builds
- Cast to time_t in Datetime::operator+/- (libshared): time_t is 32-bit
on i386, so the braced return narrowed int64_t and clang rejected it
with -Wc++11-narrowing. Only needed on 32-bit architectures, so apply
the patch through EXTRA_PATCHES when ARCH is i386 instead of always.
- Stop upstream from compiling -DTASK_TEST_RCDIR="${CMAKE_SOURCE_DIR}/doc/rc"
into the binary for Debug builds: WITH_DEBUG made the binary write
"include <WRKSRC>/doc/rc/default.theme" into every generated .taskrc,
breaking it once the work directory is removed. Also drop the
ineffective -DCMAKE_BUILD_TYPE=release (Uses/cmake.mk appends its own
CMAKE_BUILD_TYPE afterwards, which always wins).
[clangd] Enforce SymbolKind YAML coverage with -Wswitch (#225945)

[RISCV] Combine two consecutive VSLIDEDOWN_VL nodes into one (#225232)
Given this pattern
```
%down0 = RISCVISD::VSLIDEDOWN_VL undef, %val, %offset0, %mask, %vl0
%down1 = RISCVISD::VSLIDEDOWN_VL undef, %down0, %offset1, %mask, %vl1
```
we can turn it into
```
%down1 = RISCVISD::VSLIDEDOWN_VL undef, %val, %offset2, %mask, %vl1
```
where %offset2 is `%offset0 + %offset1`, if `%vl0 >= %offset1 + %vl1`.
[BOLT] Make .debug_names emission reproducible (#225218)
--update-debug-sections does not produce the same binary twice when the
input has a .debug_names section, or is given one with
--create-debug-names-section. Three sections vary from run to run:
.debug_str, .debug_names and .debug_str_offsets. On a two-CU split-DWARF
test binary, ten runs of the same llvm-bolt produced three different
outputs.
PR #197859 made the per-bucket work merge in partition order precisely
so the output would be reproducible, but missed this section. Two
issues:
- .debug_str offsets were handed out from the workers, so main.dwo.dwo
added by the merge step lands in a different place in each run. The
string offsets stored in .debug_names follow from it, and so does
.debug_str_offsets;
- hash colliding names were ordered by insertion (worker) order, also
non-deterministic.

[CIR] Fix the order of temporary object cleanup (#225560)
We had a problem in CIR where we were performing cleanups in the wrong
order when conditional and unconditional cleanups were needed for
temporary objects created in a single expression. The unconditional
cleanups were being emitted as they occur, while the conditional
cleanups were deferred until the entire expression had been emitted. The
result was that conditional cleanups were performed after unconditional
cleanups, even if the unconditionally destroyed object was created
first.
This change fixes that problem by reorganizing the way conditional
cleanups are handled. A cir.cleanup.scope operation is now created
eagerly where a conditional begins rather than at the start of the full
expression, so that it nests inside the cleanup scopes of temporaries
created before the conditional and outside those created after it. Scope
nesting determines the order in which the cleanup regions run, so this
yields reverse-of-construction order. A ConditionalCleanupScope object
tracks the scope and the conditional cleanups waiting to be emitted into

[GlobalOpt] Fix constructor folding on global with explicit section. (#220729)
Make sure we don't try to emit a non-zero value into BSS, or anything

jail: set default root directory for a jail to its parent's root.
All default jail parameter values are an empty or otherwise standard
value, or are copied the jail's parent. A notable exception is the
root directory, which is instead copied from the creating process's
jail. Fix that to be in line with everything else.
This change affects only the default when no path is specified; if
a path of "/" is explicitly given, that will still be the creating
process's root directory.

[HLSLSemanticSignatures] Implement the optimal packing of elements (#218064)
Implements the optimal packing algorithm by sorting the elements in an
optimal order before sorting with prefix packing. This also adds an
explicit packing stage for the clip/cull signature elements that allows
them to be packed with other compatible semantic types.
Resolves: #205874.
