[ELF,test] Improve error message tests
They have multiple `not ld.lld` commands or they test multiple error
messages. Add --implicit-check-not=error: to catch unexpected errors.
While updating them, use directory isolation pattern and simplify
filenames where appropriate.
Rename abs-conflict.s to conflict-abs.s to be consistent with other
conflict*.s tests.
[RISCV] Correct lowering of ISD::SETGE/SETULE/SETLE/SETUGE in lowerVPSetCCMaskOp. (#179801)
XOR should be OR to match the comment.
Found while reviewing #179622 which deletes this function. I would like
to commit this first so we have a correct baseline for reviewing that
patch.
[clang][bytecode] Fix stack corruption in pointer arithmetic discard (#176555)
The bytecode compiler was ignoring the DiscardResult flag in
VisitPointerArithBinOp
, causing pointer addition and subtraction results to persist on the
stack when they should have been popped (e.g., in comma expressions).
This led to stack corruption and assertion failures in subsequent
operations that encountered an unexpected pointer on the stack.
This patch refactors the unified addition/subtraction logic to ensure
the result is properly popped when DiscardResult is true.
Fixes #176549
[MachinePipelner] Add loop-carried dependencies for global barriers (#174391)
The loads/stores must not be reordered across barrier instructions.
However, in MachinePipeliner, it potentially could happen since
loop-carried dependencies from loads/stores to a barrier instruction
were not considered. The same problem exists for barrier-to-barrier
dependencies. This patch adds the handling for those cases. The
implementation is based on that of `ScheduleDAGInstrs::buildSchedGraph`.

[flang] Disable various semantic checks for descriptor dummy args with ignore_tkr(c) (#179530)
When descriptor dummy args have ignore_tkr(c), we want to use the
descriptor unchanged. As such, disable various semantic error checks
that are normally performed on descriptor based dummy args without
ignore_tkr(c)
[DA] Add tests for dependencies are missed due to large BTC (NFC) (#179664)
For some dependence tests, there are corner cases where `BTC <s 0`. This
patch adds test cases for those situations. Notably, in these tests,
dependencies are missed even though no overflow occurs.
powerpc64/pmap: No need to use r0 anymore in tlbie
The only use of `tlbie %rN, 0` is now explicit and covered in the block
above. Since there's no need for an explicit `tlbie %rN, 0` now, drop
this convoluted piece and let the compiler decide.
While here, a trivial optimization of the old-style tlbie block, by
clearing tlbie_lock and returning, instead of going to the end which
checks again if the lock is needed. Since it's already known to be
needed, there's no need to check again.

[asan] Disable strict init checking on AIX (#178012)
The `__cxa_atexit` interceptor is disabled for `SANITIZER_AIX` because
Clang on AIX neither uses `__cxa_atexit` nor links against a library
with such. This interceptor calls `StopInitOrderChecking()`, which is
needed to prevent false positives for the `initialization-order-fiasco`
error observed in the asan test `init-order-atexit.cpp` that uses the
`strict_init_order` flag. For now, we'll disable the `strict_init_order`
flag, but we'll look to support it in the future by implementing an
`exit` interceptor or some other alternative. With the flag disabled, we
won't update `init-order-atexit.cpp` to ensure it continues to pass and
the false positive doesn't show up.
tpm20: fix suspend/resume and entropy harvesting
There were a few problem here:
- TPM2_Shutdown results in a response that we need to either process
or ignore, otherwise any tpm20_write or tpm20_harvest call will
trivially hang on an `sc->pending_data_length != 0`
- We should have a matching TPM2_Startup upon resume to restore any
state that should have persisted
- We must drain the harvest task before we suspend to avoid problems
there
This commit is sufficient to avoid breaking suspend/resume.
