I believe the origin issue in PR31864 has been addressed by https://reviews.llvm.org/D59566.
As discussed in https://github.com/llvm/llvm-project/issues/53840, `ATOMIC_LLONG_LOCK_FREE == 2` sometimes is not consistent with `std::atomic<long long>::is_always_lock_free`, since the macro takes `long long`'s ABI alignment into account. https://reviews.llvm.org/D28213 proposed we should not rely on ABI alignment of types, thus we have consistent `ATOMIC_LLONG_LOCK_FREE` and `std::atomic<long long>::is_always_lock_free` on x86's old cpu. Currently, I plan to move on to remove the workaround which should have been addressed and don't want to break current tests.

This ensures the right order in the sink-after map is maintained. If we
re-sink an instruction, it must be sunk after all earlier instructions
have been sunk.

This is a reassociation + factoring fold. The common shift operation is moved
after a bitwise logic op on 2 input operands.
We get simpler cases of these patterns in IR, but I suspect we would miss all
of these exact tests in IR too. We also handle the simpler form of this plus
several other folds in DAGCombiner::hoistLogicOpWithSameOpcodeHands().
We should not emit a tail agnostic vlse for a tail undisturbed vmv.s.x
In D119688:
- if (IsScalarMove && !Node->getOperand(0).isUndef())
+ bool HasPassthruOperand = Node->getOpcode() != ISD::SPLAT_VECTOR;
+ if (HasPassthruOperand && !IsScalarMove &&
!Node->getOperand(0).isUndef())
break;
The IsScalarMove check in the if statement had been changed.

setgt X, -1 is the canonical form of setge X, 0. We can swap the
select operands and use setlt X, X0 when selecting CMOV. This
avoid materializing the -1 in a register.
We were relying on HandleLLVMOptions adding this flag, but that's not
included in compiler-rt. Add the flag explicitly ourselves to ensure
it's present; the duplication of the flag in the parts of the build
which do include HandleLLVMOptions doesn't cause any issues.

ObjFile::parse combines symbol initialization and resolution. Many tasks
unrelated to symbol resolution can be postponed and parallelized. This patch
extracts local symbol initialization and parallelizes it.
Technically the new function initializeLocalSymbols can be merged into
ObjFile::postParse, but functions like getSrcMsg may access the
uninitialized (all nullptr) local part of InputFile::symbols.

addWrappedSymbols may trigger archive extraction: split stack implementation
uses --wrap=pthread_create, which extracts libgcc.a(generic-morestack-thread.o).
This fixes the regression caused by 09602d3b47 by
making the invariant satisfied: no more non-compileBitcodeFiles object file is
produced at postParseObjectFile.
We previously had logic to disable pthreads, set the ThreadModel to Single, and
disable thread-safe statics when the atomics target features is disabled, since
that means that the resulting program will not be used in a threaded context.
Similarly check for the presence of the bulk-memory feature, since that is also
necessary to produce multithreaded programs.

This commit adds a new hook Pass `bool canScheduleOn(RegisteredOperationName)` that
indicates if the given pass can be scheduled on operations of the given type. This makes it
easier to define constraints on generic passes without a) adding conditional checks to
the beginning of the `runOnOperation`, or b) defining a new pass type that forwards
from `runOnOperation` (after checking the invariants) to a new hook. This new hook is
used to implement an `InterfacePass` pass class, that represents a generic pass that
runs on operations of the given interface type.
The PassManager will also verify that passes added to a pass manager can actually be
scheduled on that pass manager, meaning that we will properly error when an Interface
is scheduled on an operation that doesn't actually implement that interface.

Previously, this test snippet would report incorrect information:
F::mask m;
std::wstring in(L"\u00DA"); // LATIN CAPITAL LETTER U WITH ACUTE
f.is(in.data(), in.data() + 1, &m);
// m & F::lower would be set
The single-character version of the `is` function wasn't
affected by this issue though.
Define `_LIBCPP_CTYPE_MASK_IS_COMPOSITE_ALPHA` for Windows,
as the `alpha` / `_ALPHA` constant is a mask consisting of
multiple bits set, which avoids setting `alpha` whenver any
of the bits is set, in the `do_is` implementation.
On Windows, with the "C" locale, wchars are classified according
to their Unicode interpretation, just as in the en_US.UTF-8 locale on
all platforms.
Due to the differing classification of some characters, the
`scan_is` and `scan_not` tests are quite annoying to fix, thus just
ifdef out some of the tests for the "C" locale there - the code gets
tested with the more standard en_US.UTF-8 locale anyway.
