[PowerPC] Simplify lowering for ldat intrinsics
This change defines 2 new output patterns, `PAIR8` and `EVEN8`,
and uses them to implement the lowering of the intrinsics
`int_ppc_amo_ldat` and `int_ppc_amo_ldat_cond` in TableGen.
As result, the generated instructions are much clearer, and the
C++ code is also simplified.
[asan_abi] Skip new __asan_get_report_* from ABI (#194463)
PR #181446 ("[asan] API for getting multiple pointer ranges") added five
new __asan_get_report_{dealloc,dest,first,second,src}_address entries to
compiler-rt/lib/asan/asan_interface.inc without updating
asan_abi_tbd.txt
or implementing them in compiler-rt/lib/asan_abi/asan_abi.cpp. This
broke
the AddressSanitizerABI-arm64-darwin ::
Darwin/llvm_interface_symbols.cpp
test, which diffs asan_interface.inc (minus asan_abi_tbd.txt) against
the
symbols actually exported by libclang_rt.asan_abi_osx.a.
List the new symbols alongside the existing __asan_get_report_* entries
so the stable-ABI test passes. The symbols remain unimplemented in the
stable ABI library; this change only reflects that they are
intentionally
not part of the stable ABI surface.

[VectorCombine] reject out-of-bounds extract indexes in foldExtractExtract (#194381)

lldb] Fix two issues causing TestEvents.py flakiness (#194438)
This PR fixes two issues that contribute to `TestEvents.py` being flaky
in CI:
1. `ProcessEventData::DoOnRemoval` runs the full stop-handling logic
(like `ShouldStop` and `RunStopHooks`) every time an event is consumed
from any listener. When the primary listener consumes an event and then
the shadow listener consumes the same event, the logic runs twice. The
second execution can race with subsequent event processing. Fix this by
incrementing `m_update_state` after the first successful run so
secondary listeners skip the full logic.
2. Target::RunStopHooks updates `m_latest_stop_hook_id` (marking a stop
as "handled") before checking whether any threads have stop reasons. If
the check fails and hooks don't run, the stop ID is already consumed,
preventing hooks from ever running for that stop. Fix this by deferring
the update until we're certain we'll actually run hooks.
lang/python/wheel.mk: Clarify PY_RENAME_BINARIES
Use "files" not "binaries" as this works with python scripts :-).
Don't parenthesize ("in $PREFIX}/bin") because that's a critical
definition, not a reminder.
Suggest adding ALTERNATIVES for cases when the program would be run by
humans expecting an unversioned name.

Reland "[llvm-profgen] Add support for ETM trace decoding" (#194465)
This relands commit e3bd61890e68303a33fdd33fbdd9abeda (#191584), which
was reverted in commit
ec9d7d18bdfe21c30c94c02f14f3613f7b69a17b (#194087) due to bot failures
on ppc64le and Windows.
This reland incorporates the following fixes:
1) Rename member variable InputFile to InputFilePath inside struct
InputFile to resolve MSVC shadow
conflicts.
2) Add arm-registered-target to ETM tests REQUIRES directive to prevent
failures on builders that do
not have the ARM target enabled.
[libc][test] Remove non-proxy header in sendmsg_recvmsg_test.cpp (#194467)
The header `include/llvm-libc-macros/linux/sys-socket-macros.h` should

LIBC_FULL_BUILD is enabled. Else we mix LLVM-libc internal headers and
system headers.
packages: Fix clang conditional
Various src.conf options can cause us to build something that ends up
in the clang package, but MK_TOOLCHAIN is not one of them; copy the
proper conditional from lib/Makefile to decide if we need to build
the package.
This fixes the build when LLVM/clang is entirely disabled.

[lldb] Unify python shebangs (#187257)
As per PEP-0394[1], there is no real concensus over what binary names
Python has, specifically 'python' could be Python 3, Python 2, or not
exist.
However, everyone has a python3 interpreter and the scripts are all
written for Python 3. Unify the shebangs so that the ~50% of shebangs
that use python now use python3.

[Offload][libsycl][clang-sycl-linker] Simplify SYCL Offload wrapping (#193876)
Replace the __sycl_tgt_bin_desc/__sycl_tgt_device_image-based fat binary
registration with a simpler OffloadBinary-native approach:
- __sycl_register_lib/__sycl_unregister_lib now take (BinaryStart, Size)
instead of a __sycl_tgt_bin_desc pointer; __sycl_unregister_lib only
needs BinaryStart since the runtime looks up the binary by its start
address.
- OffloadWrapper's SYCL wrapping is significantly simplified: the
__tgt_bin_desc/__tgt_device_image structs and the descriptor
construction code are replaced by a single embedded OffloadBinary blob
passed directly to the register/unregister entry points.
- clang-sycl-linker generates a single OffloadBinary, which contains
multiple images.
- ProgramAndKernelManager::registerFatBin parses the blob via
OffloadBinary::create, keying MDeviceImageManagers by BinaryStart to
eliminate the reparse on unregister.
- DeviceImageManager owns std::unique_ptr<OffloadBinary> instead of

[CIR] Eliminate SymbolTable::lookupSymbolIn hotspots (#193362)
mlir::SymbolTable::lookupSymbolIn is O(n) per lookup, so cumulative
symbol lookups during CIRGen are O(n^2) in the number of global symbols.
On template-heavy translation units this becomes a significant
compile-time hotspot.
Replace the SymbolTable lookup path with a per-CIRGenModule DenseMap
cache keyed by symbol name, giving O(1) lookups.
On a synthetic template-heavy stress test, end-to-end compile time on
`clang -fclangir -S -emit-llvm -O0` improves by ~11% on a 33K-LOC input
(5.86s -> 5.21s) and ~16% on a 67K-LOC input (16.09s -> 13.52s). The
super-linear growth of the win with input size confirms the O(n^2) ->
O(n) effect.
Similar to previous compile time fix, repro shape (scale records and
template instantiations into the hundreds/thousands to amplify):

libzpool: Set -Wno-error=typedef-redefinition for clang
In some versions of LLVM (at least 21), the <*intrin.h> headers contain
unguarded duplicate typedefs; this isn't permitted prior to C11, and
libzpool is built as C99. FreeBSD's LLVM backported LLVM PR #153820
to fix this, but other versions of LLVM (e.g., upstream, or on Linux)
don't have the patch, so this breaks the build.
Add -Wno-error=typedef-redefinition to downgrade this from an error
to a warning.
