[DWARFLinker] Index Swift mangled type names in the parallel linker (#216429)
Swift records a type's mangled name in DW_AT_linkage_name. The classic
linker indexes it as a type accelerator entry alongside the short
DW_AT_name, but the parallel linker indexed only the short name.
Port the DW_LANG_Swift block added to the classic linker in 8234f8ae2685
to the parallel linker's type case.
libxml2: update to 2.15.3.
From Showta Ishizaki in PR 60591.
v2.15.3: Apr 15 2026
### Security
- parser: Pass userData to SAX text callbacks in xmlParseReference (type-confusion)
- entities: copy children in xmlCopyEntity
- c14n: Fix Type confusion in xmlC14NProcessAttrsAxis
- python: Do not decref string after adding to the list (double-free / use-after-free)
- c14n: Reuse tmp_str, xmlStrcat reallocates *cur (double-free)
### Improvements
- schemas: Fix relative schemaLocation resolution in XSI assembly in streaming mode
- xmlreader: propagate reader resource loaders to validator parsers
- python: Make python bindings python2 compatible

[SLP]Recalculate copyable-element deps after tree reordering
Reordering permutes the operand columns of the entries and may move an
operand between copyable-covered and plain edges, making the computed
dependency counts stale and tripping the unscheduled-deps assertion.

[RISCV] Remove short-forward-branch-imm. (#216401)
Just use short-forward-branch-ialu. I hope implentations that implement
short-forward-branch, do it equally for all branch types. Doing anything
else would create complex tradeoffs.
I'm planning to add conditional c.mv fusion support for Zibi and I don't
want to add an immediate version flag there.
The patterns that checked NoShortForwardBranchImm were not checking that
an immediate branch ISA was enabled. So I've changed them to
NoVendorXqcibiOrNoShortForwardBranch.
[NFC][SLP] Add a test for fma fusion with the fmul on operand 1 (#216428)
canConvertToFMA only looks at operand 0 of the fadd, so the accumulator
shape fadd c, a * b is never recognised, and the fmul it does find is
priced with the target's fusion discount already applied. The threshold
puts the decision right at the cost boundary so the checks record which
way SLP goes today.
[DWARFLinker] Constrain a function's high_pc to its own symbol (#216432)
Mach-O objects built with .subsections_via_symbols make every symbol an
independently placeable atom, and the linker packs atoms without
preserving the spacing they had in the object file.
I have an example where the compiler describes such a subprogram as
extending past its own atom. While it's debatable whether that's a good
idea, it's not invalid in the object file. However, once linked, it is
invalid.
We can make dsymutil resilient against this by looking at the size of
the symbol in the debug map and adjusting the end_pc. I'm doing so
conservatively so that only a collision is repaired. Already
overlapping/invalid ranges remain untouched.

[LLVMABI] Create a skeleton for AArch64 ABI handling (#216222)
This change adds the most basic implementation of llvm::abi::TargetInfo
for AArch64 targets and establishes a unit test for it.
There was no isolated testing for previous targets implemented in the
ABI library. They were only tested through clang. My plan with AArch64
is to create unit tests so that the library can be tested without
building the clang target, but also to have clang tests so that the
handling can be compared to clang's ABI handling as a meaningful point
of reference for correct behavior.
For this initial change, because no real handling is implemented yet, I
am not introducing the clang hook or any clang-based tests.

[lldb] Search for a corefile's images before loading any of them (#216431)
A userland or kernel corefile can list hundreds of images, and searching
for one can shell out to a symbol server or fetch over the network.
Searching for them one at a time is where loading such a corefile spends
its time.
Add a batch form of SymbolLocator::Locate that runs the searches on the
debugger's thread pool, gated on target.parallel-module-load. Results
come back in the order the requests were given, since that order decides
the Target's module order. Only the results are ordered, and anything a
search reports to the user arrives in whatever order the searches finish
in.
Only the plugin searches run concurrently, so a platform hook does not
have to be thread safe to take part, and reading a binary's UUID out of
memory stays on the calling thread.
Setting up a platform binary can replace the Target's platform and
