[ELF] Add target-specific relocation scanning for LoongArch (#182236)
Implement LoongArch::scanSectionImpl, following the pattern established
for x86, PPC64, SystemZ, AArch64. This merges the getRelExpr and TLS
handling for SHF_ALLOC sections into the target-specific scanner,
enabling devirtualization and eliminating abstraction overhead.
- Inline relocation classification into scanSectionImpl with a switch
on relocation type, replacing the generic rs.scan() path.
- Use processR_PC/processR_PLT_PC for common PC-relative and PLT
relocations.
- Inline TLS handling: IE->LE optimization for _PC_ variants only (not
_PCADD_ or absolute), TLSDESC->IE/LE for non-extreme code model,
GD/LD flag setting without going through generic handleTlsRelocation.
- Remove adjustTlsExpr by inlining its logic into scanSectionImpl.
- Remove LoongArch-specific code from Relocations.cpp:
handleTlsRelocation, execOptimizeInLoongArch, and the sort condition.
- Simplify getRelExpr to only handle relocations needed by
relocateNonAlloc, scanEhSection, and the extreme code model fallback
in relocateAlloc.
[MC][test] Add relax-branch-align.s demonstrating unnecessary branch relaxation (#184551)
The two-pass relaxation approach (relaxFragment, then layoutSection)
can unnecessarily relax a backward branch from short (2B) to near (5B).
When a forward branch relaxes (2B->6B), it shifts the backward target
by +4B. A .p2align between target and source absorbs this growth. The
true displacement is -125 (fits short), but the two-pass approach
evaluates the backward branch with stale target offsets, seeing -129
(beyond [-128,127]) and relaxing it unnecessarily.

[engine] [bug]
Fixed a critical issue in Engine where connections created in conjunction with the DialectEvents.do_connect() event listeners would receive shared, mutable collections for the connection arguments, leading to a variety of potential issues including unlimited growth of the argument list as well as elements within the parameter dictionary being shared among concurrent connection calls. In particular this could impact do_connect routines making use of complex mutable authentication structures.
[RISCV] Sink instructions so AVL dominates in RISCVVLOptimizer (#184155)
The last feature that RISCVVectorPeephole::tryToReduceVL has that
RISCVVLOptimizer doesn't is that if the vl to reduce to doesn't dominate
a vector pseudo, it can sink the pseudo below the vl definition if it's
safe to do so.
This PR shares the logic to check for physical register clobbering in
RISCVInstrInfo, but there may be a better place for it.
The DemandedVLs DenseMap needs to be switched to a MapVector to get
deterministic ordering, since the order in which we sink instructions
can affect the resulting codegen.
This helps removes a few vsetvli toggles in llvm-test-suite.

ZLB-01-002: infinite loop in crc32_combine{,_op}()
zlib.h and our compress(3) manual have documented that len2 in the two
affected APIs must be non-negative for a long time. If you ignore this,
you hang, as a simple test shows. The trivial fix adds a corresponding
check and makes the documentation even more explicit.

Check for negative lengths in crc32_combine functions.
Though zlib.h says that len2 must be non-negative, this avoids the
possibility of an accidental infinite loop.
[DA] Add tests that represent edge cases for the Weak Zero SIV tests (NFC) (#183735)
This patch adds test cases that capture edge cases for the Weak‑Zero SIV
tests. These cases involve loop‑invariant, non‑constant variables, and
special care is required when those variables may be zero.
[GVN] Fix crash when svcount is used with globals-aa (#184347)
When -globals-aa is used, `analyzeLoadAvailiability` calls
`analyzeLoadClobberringStore` which in turn calls
`isFirstClassAggregateOrScalableType` which is using
`isa<ScalableVectorType>`. Ideally it should use type's isScalableType()
method.
The crash does not occur when default (BasicAA) is used because
`analyzeLoadAvailiability` function does not take the load clobbering
path as BasicAA returns `Def`.

[RISCV] Remove OperandType OPERAND_SIMM10_UNSIGNED. Rename OPERAND_SIMM8_UNSIGNED->OPERAND_SIMM8 (#184540)
The UNSIGNED only refers to what we allow in assembly parsing. The
MachineInstr/MCInst should always be canonicalized to signed.
www/py-yt-dlp-ejs: Remove the IGNORE line
This do-fetch target does not repackage anything.
It fetches the tarball, extracts it, then fetches NodeJS dependencies
into the same folder, and packages this folder as a final tarball
used during build.
AFAIK there is nothing wrong with this port the way it is now.
This can't be done in post-extract due to internet access that is
required.
