[flang][cuda] Fix predefined variable processing with inlining (#205888)
The pass was skipping some variables when they were inlined inside a cuf
kernel for example.
[LV] Use getSmallBestKnownTC in IV-overflow-check (#195226)
It has the benefit of also handling scalable TCs.

[AArch64] Fix stack protectors with tiny code model. (#205668)
The tiny code model was using the address of the stack protector as the
stack protector, which doesn't provide the expected protection. Fix it
to use the usual adrp+ldr.
[CIR] Fix return type of __cxa_atexit (#205905)
The return type should be 'int', not 'void'. We even have a comment
above the code that generates this that it should be an int.
This patch changes it and updates all the affected tests.
NAS-141469 / 27.0.0-BETA.1 / Fix AD keytab freshness check and recovery churn (#19184)
last_password_change read the secrets.tdb timestamp with a stray ']' in
the key, so it always returned None and check_updated_keytab re-ran the
secrets backup + keytab store hourly. Drop the bracket.
Also cut directory-services recovery churn when AD is FAULTED: fast-fail
the winbind start in idmap.__wbclient_ctx rather than restarting per SID
lookup, cap the directoryservices_change job queue, and fix
get_db_secrets UnboundLocalError on invalid JSON.
Expand CI tests to cover regression.

[CIR] Implement ArgKind::Expand in CallConvLowering (#201718)
ArgKind::Expand classifies a struct argument for flattening: each field
becomes a separate scalar argument at the ABI level. Classic CodeGen
calls this "struct expansion" — used on targets like MIPS and some ARM
calling conventions.
CIRABIRewriteContext previously emitted errorNYI at both classification
sites. The replacement covers three call paths. In buildNewArgTypes,
the original struct type is replaced by one wire type per field. In
insertArgCoercion, the single struct block argument is replaced by N
scalar block arguments and an alloca+get_member+store+load sequence at
the entry block reassembles them for body uses; a running block-argument
index (rather than classIdx + sretOffset) correctly tracks the expanded
slot count when multiple Expand args or sret+Expand combinations appear.
The Ignore-drop loop gains a classToBlockArg pre-computation so that
Ignore args following Expand args are erased at the correct index. In
rewriteCallSite, cir.extract_member decomposes the struct operand into
its constituent fields, which become separate call arguments.

[clang][index][USR] GenLoc prints file entry at most once, allow repeated offsets (#205430)
`GenLoc` previously printed the source location at most once per USR,
gated by a member flag toggled on the first call. During the recursive
visit, if both an outer and an inner decl needed to print the location,
only the outer one was printed. When the outer decl did not need the
offset, no offset was ever printed. For example, the USR of
`Holder<decltype([]{})>::method` depends on the location of the type of
the lambda but the outer decl prints the file entry only, which disables
offset printing.
Change the logic so the file-entry part of the location is printed at
most once (it must be identical), while offsets of sub-decl locations
may be printed multiple times.

[Offload] Unify the kernel argument passing (#205224)
Summary:
Currently we have two conflicting methods of passing kernel arguments, a
flat pointer + size and an array of pointers. We recently decided to
move the offload API to the latter because it is more generic and lets
you construct the other formats.
This PR primarily just changes the format and the one existing core use.
The uses should be simplier now. Future changes will change the OpenMP
argument parsing.
[Clang] Disable C++ exceptions by default for GPU targets (#205402)
Summary:
Exceptions are not supporter, and likely will never be supported, on
GPUs. The SIMT model makes context switching nearly impossible, and
building an unwinder would require stashing a register file that is
over 8 KiB these days. There's precedent to disable this for the target,
so we should just do this.
Offloading languages have their own weird handling, some chimera that
just accepts exceptions but turns them into traps on the device side, so
we leave that unaffected.
[mlir] Fix visitor block erasure (#205854)
I made the visitor test drop block-defined value uses before erasing the
block and added a small regression case.

AMDGPU: Avoid default subtarget in hand-written codegen tests (9/9) (#205792)
Fix some manual test checks using amdgcn triples without -mcpu. These
require the most careful consideration. The highest impact changes are the
optimizations removing execz branch now that there's a sched model.
AMDGPU: Avoid default subtarget in hand-written codegen tests (8/9) (#205791)

AMDGPU: Avoid default subtarget in hand-written codegen tests (7/9) (#205790)
Introduce an -mcpu argument to tests missing it to avoid codegening
the default dummy target. These are cases that didn't require adjusting
the check lines.
