[SystemZ] Emit external aliases for indirect function descriptors in the ADA section (#183443)
This is the last of the three patches aimed to support indirect symbol
handling for the SystemZ backend.
An external alias is emitted for indirect function descriptors within
the ADA section, rather than a temporary alias, while also setting all
of the appropriate symbol attributes that are needed for the HLASM
streamer to emit the correct XATTR and ALIAS instructions for the
indirect symbols.
Moreover, this patch updates the
`CodeGen/SystemZ/zos-ada-relocations.ll` test as the ADA section is
currently the only user of indirect symbols on z/OS.
Depends on https://github.com/llvm/llvm-project/pull/183442.
[SLP] Reject duplicate shift amounts in matchesShlZExt reorder path (#183627)
In the reordered RHS path of matchesShlZExt, the code never checked that
each shift amount (0, Stride, 2×Stride, …) appears at most once. When
the same shift appeared in multiple lanes, it still filled Order,
producing a non-permutation (e.g. Order = [0,0,0,1]). That led to bad
shuffle masks and miscompilation (e.g. shuffles with poison).
The patch adds an explicit duplicate check: before setting Order[Idx] =
Pos, it ensures Pos has not been seen before, using a SmallBitVector
SeenPositions(VF). If a position is seen twice, the function returns
false and the optimization is not applied.
[clang][ssaf] Add `JSONFormat` support for `TUSummaryEncoding`
This PR adds `JSONFormat` support for reading and writing
`TUSummaryEncoding`. The implementation exploits similarities in the
structures of `TUSummary` and `TUSummaryEncoding` by reusing existing
`JSONFormat` support for `TUSummary`. Duplication of tests has been
avoided by parameterizing the test fixture that runs all relevant
read/write tests against `TUSummary`, for `TUSummaryEncoding`. This
ensures that the two serialization paths remain in lockstep.
[SlotIndexes] Further pack indices to improve spill placement time (#182640)
This patch makes it so that renumbering indices when inserting
instructions into the SlotIndexes analysis renumbers the entire list if
the list is otherwise densely packed. This fixes a case we saw on
AArch64 with a lot of spills where every single spill instruction
insertion required a renumbering of most of the instructions in a large
function, making the operation approximately quadratic.
This is not NFC as heuristics depend on the SlotIndex numbers, although
this should mostly be a wash as LRs should be extended ~equally.

[WebAssembly] Incorporate SCCs into WebAssemblyFixIrreducibleControlFlow (#181755)
Rather than mapping out full "reachability" between blocks in a region
to find loops and using `LoopBlocks` to find the bodies of said loops,
use SCCs (strongly-connected components) to provide this information.
This brings in LLVM's generic `SCCIterator` (which uses Tarjan's
algorithm) as the implementation for sorting the basic blocks of the CFG
into their SCCs.
This PR greatly reduces the compile-time footprint of the pass, making
memory use and time taken negliable where it might have previously
caused stalls and OOM before (e.g. #47793,
usagi-coffee/tree-sitter-abl#114)

[mlir][LLVM] Let decomposeValue/composeValue handle aggregates (#183405)
This commit updates the LLVM::decomposeValue and LLVM::composeValue
methods to handle aggregate types - LLVM arrays and structs, and to have
different behaviors on dealing with types like pointers that can't be
bitcast to fixed-size integers. This allows the "any type" on
gpu.subgroup_broadcast to be more comprehensive - you can broadcast a
memref to a subgroup by decomposing it, for example.
(This branched off of getting an LLM to implement
ValueuboundsOpInterface on subgroup_broadcast, having it add handling
for the dimensions of shaped types, and realizing that there's no
fundamental reason you can't broadcast a memref or the like)

[lldb-dap] Adjust VariableReferenceStorage lifetime management. (#183176)
Adjusting `VariableReferenceStorage` to only need to track permanent vs
temporary storage by making `VariableStore` the common base class.
Moved the subclasses of `VariableStore` into the Variables.cpp file,
since they're no long referenced externally.
Expanding on the tests by adding an updated core dump with variables in
the argument scope we can use to validate variable storage.

[flang] [flang-rt] Addition of the Fortran 2023 TOKENIZE intrinsic. (#181030)
This implements the TOKENIZE intrinsic per the Fortran 2023 Standard.
TOKENIZE is a more complicated addition to the flang intrinsics, as it
is the first subroutine that has multiple unique footprints. Intrinsic
functions have already addressed this challenge, however subroutines and
functions are processed slightly differently and the function code was
not a good 1:1 solution for the subroutines. To solve this the function
code was used as an example to create error buffering within the
intrinsics Process and select the most appropriate error message for a
given subroutine footprint.
A simple FIR compile test was added to show the proper compilation of
each case. A thorough negative path test has also been added, ensuring
that all possible errors are reported as expected.
