Revert "[clang] fix matching constrained out-of-line definitions of class specialization member function templates" (#193558)
Reverts llvm/llvm-project#192806 , which is causing the compiler to
reject some valid code.
Loosen check for clang version string in test to work when setting CLANG_VENDOR. (#192961)
We are trying to update our buildbot to use the `-DCLANG_VENDOR` and
`-DCLANG_VENDOR_UTI` options, but need to fix some tests first. This is
one of them.

IR: Allow !fpmath metadata on homogeneous float structs
This matches the logic for fast math flags / nofpclass, and allows
marking llvm.sincos calls with !fpmath.
[GlobalISel] Change SSUBO to do (LHS < RHS) XOR (RESULT < 0) (#191744)
Refactor lowerSADDO_SSUBO in LegalizerHelper so addition and subtraction
use separate, clearly named paths.
SADDO: unchanged meaning: overflow when (result < LHS) disagrees with
(RHS < 0) (signed compares).
SSUBO: use the equivalent formulation: overflow when (LHS < RHS)
disagrees with (result < 0) instead of (result < LHS) vs (RHS > 0).
[libc] Replace check-libc with lit-based test execution (#184163)
Now that check-libc-lit has been validated alongside check-libc, make
lit the default test runner by renaming check-libc-lit to check-libc.
Remove the old CMake-driven check-libc custom target.
[VPlan] Use MaxRuntimeStep in materializeVectorTC to simplify middle br. (#193067)
For scalable vectors, pass the maximum runtime step to
materializeVectorTripCount. Use it to simplify the vector trip count to
the original trip count directly, if MaxRuntimeSteps divides the
original trip count without remainder.
In those cases, all lower power-of-2 vscales will divide the rip count
without remainder.

[compiler-rt] [Darwin] Enable arm64e tests on macOS (#193391)
This enables compiler-rt tests on Darwin arm64e (when supported by the
linker).
Note that arm64e is not enabled for sanitizers yet, but this does add
test coverage for builtins.

[NFC][MachineBlockHashInfo] Add static asserts to guard agains hash_16_bytes changes (#192862)
`hashing::detail::hash_16_bytes` is not guaranteed to be stable across
different versions of LLVM, it can change any time.
We put asserts here, so if it changed, author don't forget to work
around them here.
Revert "[SelectionDAG] Salvage debuginfo when combining load and z|s ext instrs. (#188544)" (#193554)
This reverts commit fe5d5b762ab3b92b18b56f413965abb81a459ac6.
Reverted because of https://github.com/llvm/llvm-project/issues/193475
clang crashes on valid code at -O{2,3} on x86_64-linux-gnu: Assertion
`N->getOpcode() != ISD::DELETED_NODE && "DELETED_NODE in CSEMap!"'
failed
[lldb] Scope symbol lookups to specific modules in ObjC/SystemRuntime plugins (#193379)
This narrows `FindSymbolsWithNameAndType` calls from searching all
loaded images to the specific module that owns the symbol (Foundation,
CoreFoundation, libBacktraceRecording.dylib).
The arclite fallback in `CalculateHasNewLiteralsAndIndexing` still
searches all images because libarclite is a static library linked into
the main executable.
[Runtimes] Allow HandleLibc.cmake to be called multiple times (#193540)
Summary:
This needs to check to see if it's already been called now that we want
to use it more places than just libcxx.

The i915 DRM driver started to replace the use of `struct page` by

linuxkpi were missing a few more functions: `kmap_local_folio()`,
`memcpy_to_folio()` and `offset_in_folio()`. They are equivalent of
their `struct page` counterparts.
One difference is that `kmap_local_folio()` takes an offset argument and
the returned address takes this offset into account.
