fix build by not trying to statically link sdl3
libSDL3.a does not exist but meson still tries to statically link
everything in the Requires.private part of the sdl3.pc pkgconfig file.
In the case of gbm libgbm.a had unresolved symbols.
build failure reported by tb@ who tracked this back to a change in the
devel/sdl3 port to build with -DSDL_DEPS_SHARED=OFF

[libc++] Remove non-standard member type iterator_type from __wrap_iter (#186871)
Resolves #186801
Removed the non-standard member type `iterator_type` from `__wrap_iter`.
This member exposed the underlying iterator type, and its removal
prevents users from relying on the implementation detail.
[mlir][memref] Simplify expand_shape size/stride computation using output_shape (#187844)
This PR refactors `getExpandedSizes` and `getExpandedStrides` to compute
their results directly from the `output_shape` of `memref.expand_shape`.
Instead of reconstructing expanded sizes/strides through manual
inference, we now rely on the operation’s explicit shape information.
The previous implementation imposed the restriction that there must be
at most one dynamic size per reassociation group. This limitation is
removed by the new approach: any number of dynamic dimensions within a
group is now supported, as long as they are represented in the
`output_shape`.
As a result, the code becomes both simpler and more expressive, while
better matching the semantics of `memref.expand_shape`.
[CoroSplit] Never collect allocas used by catchpad into frame (#186728)
Windows EH requires exception objects allocated on stack. But there is
no reliable way to identify them. CoroSplit employs a best-effort
algorithm to determine whether allocas persist on the stack or the
frame, which may result in miscompilation when Windows exceptions are
used.
This patch proposes that we treat allocas used by catchpad as exception
objects and never place them on the frame. A verifier check is added to
enforce that operands of catchpad are either constants or allocas.

[ORC] EPCGenericJITLinkMemoryManager from SimpleNativeMemoryMap syms. (#188391)
Adds a new EPCGenericJITLinkMemoryManager convenience constructor that
constructs an instance by looking up the given symbol names in the
bootstrap JITDylib of the given ExecutionSession.
The symbol names default to the SimpleNativeMemoryMap SPS-interface
symbol names provided by the new ORC runtime.
stand: Force disable RETPOLINE for boot loaders
Boot loaders do not require speculative execution protection, and may be
too large if enabled.

kern/amd64/machdep: Replace memset in wrmsr_early_safe_end
GENERIC-KASAN kernel failed to boot on a Dell PowerEdge C6615 with
an AMD EPYC 8224P CPU; UEFI BIOS caught a #GP exception with %RIP
in kasan_memset where %GS relative pointer (curthread->td_pflags2)
was dereferenced. Investigation led to wrmsr_early_safe_end which
calls memset to clear early #GP IDT entry. Replacing memset with
__builtin_memset_inline still resulted in the compiler emitting a
call to the memset resolver in GENERIC-KASAN build and the kernel
stil faulted during boot. This version which has been successfully
tested with both GENERIC and GENERIC-KASAN kernels uses memset_early.

[LoongArch] Fix incorrect reciprocal sqrt estimate semantics (#187621)
The current implementation of getSqrtEstimate() has incorrect semantics
when using `FRSQRTE`.
`FRSQRTE` computes an approximation to 1/sqrt(x), but the existing code
multiplies the estimate by the operand when Reciprocal is true. This
results in returning sqrt(x) instead of 1/sqrt(x), effectively reversing
the intended semantics of the 'Reciprocal' flag.
Additionally, the implementation does not properly account for LLVM's
Newton-Raphson refinement pipeline. When refinement steps are requested,
the initial estimate must be in reciprocal form so that the generic
DAGCombiner can apply NR iterations correctly.
This patch fixes the behavior by:
- Returning the raw FRSQRTE result when Reciprocal is true, or when
refinement steps are required.

[RISCV] Fix ssub_sat cost model to use signed VSSUB instead of VSSUBU (#188195)
Intrinsic::ssub_sat was incorrectly mapped to RISCV::VSSUBU_VV (unsigned
saturating subtract) instead of RISCV::VSSUB_VV (signed saturating
subtract), causing wrong cost estimates.

rge: make rx_process_limit a sysctl tunable
The number of packets processed per interrupt was hardcoded to 16.
Add a per-interface sysctl dev.rge.%d.rx_process_limit tunable so
users can adjust this value at runtime.
