[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

Undo botched rebase (#216421)
When rebasing #215393, I accidentally pulled in the change for #215952.
I then later rebased the latter, leaving only the changes requested
during review. Undo this mess so I can land the two PRs correctly.
[Support] Remove deprecated endian::byte_swap/read/write overloads (#216300)
These overloads took the endianness as a template parameter and were
deprecated in favour of the versions that take it as a function
argument. There are no remaining in-tree users, so drop them.

[MLIR][TableGen] Fix EnumAttr not recognized as enum in OpFormatGen (#189046)
`Attribute::isEnumAttr()` checked `isSubClassOf("EnumAttrInfo")`, but
the newer `EnumAttr` class (from `mlir/include/mlir/IR/EnumAttr.td`)
extends `AttrDef`, not `EnumAttrInfo`. This caused `canFormatEnumAttr`
in `OpFormatGen.cpp` to return `false` for `EnumAttr`-backed attributes,
forcing them to use the generic format path instead of the enum keyword
format path.
The fix has two parts:
1. Update `Attribute::isEnumAttr()` to also check
`isSubClassOf("EnumAttr")`.
2. Add `getEnumInfoRecord()` helper in `OpFormatGen.cpp` that, for
`EnumAttr`-based attributes, retrieves the `enum` sub-field (which is
the actual `EnumInfo` record) rather than the attribute def itself.
Update `canFormatEnumAttr`, `genEnumAttrParser`, and
`genEnumAttrPrinter` to use this helper.
Add a test to `op-format.td` verifying that an `EnumAttr`-wrapped enum

[clang][include-cleaner] Support ObjC @selector expressions in WalkAST (#212564)
This change adds support for resolving Objective-C @selector expressions
to their corresponding method or property declarations.
A lazy secondary pass is introduced to map selectors to their
declarations (methods, property getters, and property setters) across
the translation unit. When the AST walker encounters an
ObjCSelectorExpr, it reports the matching declarations as ambiguous
references.
[clang] Fix RecursiveASTVisitor to traverse the exception parameter in ObjCAtCatchStmt. (#216125)
Ensures that the catch parameter declaration (the exception variable) in
an Objective-C @catch block is visited during AST traversal. Previously,
this declaration was skipped. A unit test has been added to verify the
fix.
iflib: actually disable simple_tx when ALTQ is in use
When getting some baseline ALTQ numbers, I noticed that
if simlple_tx is enabled in kenv, we wind up re-setting the transmit
routine, but I neglected to actually clear ctx->ifc_sysctl_simple_tx.
That leads to many different panics as we run a mixture of mp_ring
and simple_tx.
