[SystemZ] Disable PCH on z/OS. (#185750)
The compiler supports PCH in principle, but there are occasionally
hickups. Therefore it is better to disable PCH by default.
Call dlm.reset_active when peer disconnects
Previously reset_active was only called when STANDBY reconnected, leaving
DLM RSBs in an inconsistent state for the duration of the outage. Calling
it immediately when the peer goes down ensures DLM recovery runs and repairs
pending lock lookups before SCST issues new dlm_lock requests during
logout_all.
Three guards prevent acting in the wrong context: only runs on MASTER;
skips if the peer's DLM port is still reachable (middleware-only restart);
skips if we have logged-in extents (we are STANDBY or mid-transition and
the failover event is already handling cleanup).
[CIR] Remove diagnostic when handling incomplete record types (#185715)
Following the example of classic codegen, we were checking for
incomplete record types in function signatures and issuing a diagnostic
in a place where it appeared that the type conversion needed to be
delayed. However, because CIR defers ABI processing until after codegen,
we don't actually need special handling for incomplete types.
This change removes the diagnostic and adds a comment explaining the
difference in behavior.
tests/kern/ssl_sendfile: fix 'random' and 'basic' flakyness
The read of c.sbytes needs to be synchronized with mutex. The problem was
fixed for 'truncate' and 'grow' with 8a9508563542, but these two suffer
from the same problem. Provide require_sbytes(), a locked wrapper around
ATF_REQUIRE() to reduce copy and paste.

[FLANG][MLIR][OpenMP] add MathToNVVM conversion pass to NVPTX MLIR (#180060)
This Commit adds the MLIR MathToNVVM conversion pass to flang's
NVPTX codegen lowering Math and Arith operations to libdevice library calls.
This allows support for calls to Fortran math intrinsics for OpenMP offload
for NVIDIA Targets. To support this support for -nogpulib was added for
NVIDIA targets

[lldb] Have Host::RunShellCommand ret stderr & stdout seperately (#184548)
Host::RunShellCommand takes a std::string *command_output argument and a
bool hide_stderr=false defaulted argument. If the shell command returns
stderr and stdout text, it is intermixed in the same command_output,
unless hide_stderr=true.
In SymbolLocatorDebugSymbols::DownloadObjectAndSymbolFile we call an
external program to find a binary and dSYM by uuid, and the external
program returns a plist (xml) output. In some cases, it printed a
(harmless) warning message to stderr, and then a complete plist output
to stdout. We attempt to parse the combination of these two streams, and
the parse fails - we don't get the output.
This patch removes hide_stderr and instead adds a `std::string
*separated_error_output` argument. If `separated_error_output` is
nullptr, output and error texts are returned combined in the
`command_output` argument. If a std::string object address is provided
for `separated_error_output`, then standard error output is separated

[mlir][Pass] Report error when passing options to pipelines via shorthand syntax (#185738)
When passing options to a pass pipeline that doesn't accept options,
mlir-opt exits with error code 1, but prints no error message when using
shorthand CLI syntax:
```
# Silent failure (no error message):
$ mlir-opt --tosa-to-linalg-pipeline=foo /dev/null
$ echo $?
1
# Same pipeline via --pass-pipeline syntax reports error:
$ mlir-opt --pass-pipeline='builtin.module(tosa-to-linalg-pipeline{foo})' /dev/null
<unknown>:0: error: failed to add `tosa-to-linalg-pipeline` with options `foo`
```
This PR adds replaces the silent call to `failure` with `errorHandler`
in `PassPipelineCLParser::addToPipeline`, matching the existing pattern
in `TextualPipeline::addToPipeline`.
giflib*: update to 6.1.2
Version 6.1.2
=============
Code Fixes
----------
* Fix for low-severity CVE-2026-23868 affecting gifponge, giftool, and gifbuild,
but not the core library - library clients need not be alarned.
Version 6.1.1
=============
This release bumps the major version, but only one entry point -
EGifSpew() - has changed signature and behavior (in order to be able
to pass out a detailed error code). The internal error
codes in the E_GIF_ERR series have changed value so none of them
collides with GIF_ERROR.

[X86] Add stop-gap for SDAG failure in fptrunc lowering
```
define <3 x half> @err_420(<3 x float> %0) {
entry:
%1 = fptrunc <3 x float> %0 to <3 x half>
ret <3 x half> %1
}
```
currently crashes.
\#185562 will fix this, but needs another round of review. Land a
stop-gap for now to unblock our integrate process.

[SLP] Loop aware cost model/tree building
Currently, SLP vectorizer do not care about loops and their trip count.
It may lead to inefficient vectorization in some cases. Patch adds loop
nest-aware tree building and cost estimation.
When it comes to tree building, it now checks that tree do not span
across different loop nests. The nodes from other loop nests are
immediate buildvector nodes.
The cost model adds the knowledge about loop trip count. If it is
unknown, the default value is used, controlled by the
-slp-cost-loop-min-trip-count=<value> option. The cost of the vector
nodes in the loop is multiplied by the number of iteration (trip count),
because each vector node will be executed the trip count number of
times. This allows better cost estimation.

libspl/mnttab: remove struct extmnttab
The two additional fields are never used by calling code, and we can
replace their sole internal use with an extra stack param.
