Revert "[Flang] [OpenMP] atomic compare (#184761)" (#198848)
This reverts commit 91467766a8afb52439619163828c5f6816ddd550.
This was causing tests to be quite flaky. See #198776.
[flang][OpenMP] Fix EQUIVALENCE variable privatization in OpenMP (#197726)
Fixes #197553
EQUIVALENCE aliases are lowered with `fir.ptr` addresses
(`castAliasToPointer` in ConvertVariable.cpp) to inform alias analysis.
However, `privatizeSymbol()` in Utils.cpp treated all `fir::PointerType`
values as true Fortran POINTERs, skipping the `unwrapRefType` that
computes the correct allocation type. For arrays, this caused the
privatizer to allocate pointer-sized storage instead of the full array,
resulting in stack buffer overflows at runtime.
The fix adds a `!semantics::IsPointer()` check so that only true Fortran
POINTERs preserve the `fir.ptr` wrapping. EQUIVALENCE aliases are
correctly unwrapped to their underlying type.
**Changes:**
- flang/lib/Lower/Support/Utils.cpp: Gate the `PointerType` guard on
`semantics::IsPointer` to distinguish true POINTERs from EQUIVALENCE

[AMDGPU] Fix matchPERM byte tracker for SRA past operand width (#198708)
Bytes past the operand are 0 for SRL but the sign bit for SRA. The old
code treated both as 0, so v_perm_b32 picked the wrong byte for SRA
Example:
`ashr x, 24` keeps only x's byte 0 in the result. The upper bytes are
copies of x's sign bit, not bytes of x. The matcher used to map them
back to bytes of x, producing a perm mask that ignored the sign extend

NAS-140984 / 27.0.0-BETA.1 / Active Directory: fix rejoin, harden reset/recover, improve diagnostics (#18938)
KDC Server affinity (SAF) cache stores {host, ip} dict (host captured
via a fresh CLDAP ping to the chosen kdc_server IP, so the pair
authoritatively identifies one DC). _saf_kdc_name uses the cached host
directly, avoiding RDNS in samba's --server flag and the krb5.conf kdc=
override. activate_standby accepts both the legacy single-string IP and
the new dict form for HA mixed-version upgrades.
_health_check_ad runs _test_machine_account_password only as a
refinement of a failing WBClient.ping_dc(). No krb5.conf churn on
healthy systems; AD_SECRET_INVALID fires only when ping_dc has already
failed AND the password test confirms a credential mismatch
(PREAUTH_FAILED). The temp krb5.conf the test writes now mirrors the
system config (rdns=false, dns_canonicalize_hostname=false, NAS-138687)
and is restored via a finally block so KRB5Error doesn't leave the
system config polluted.

[CI] Successful build and no tests running is now a notification (#198684)
check-libc now uses llvm-lit to run tests instead of running the
unittests directly through ninja. This means there should not be any
cases in tree where the build could succeed but we do not pick up any
tests as running. Still pass the build in this case because if
everything passes with exit code 0 it is wrong not to, but make a note
to the user that this is unexpected.
[NFC][LifetimeSafety]: Track assignment history within a single CFGBlock (#196075)
## Summary
Tracking assignment history allows us to backtrack and provide more
informative error messages, helping users better understand the root
cause.
As discussed in
https://github.com/llvm/llvm-project/pull/188467#issuecomment-4359071778,
I am splitting the original #188467 into smaller parts. This PR submits
the core logic: performing a reverse search for assignment history
within a single CFG block.
A simple unit test has been added to verify the basic functionality of
the algorithm.
