[GlobalISel] Improve bf16 converts with fast-math flags. (#200741)
This alters the lowering of bf16 G_TRUNC to exclude the check for nan if
the operation being extended is nnan. Flags are then threaded through so
that the G_FPEXT and G_FPTRUNC from promoted nodes keep the same FMF.
Replace zectl with the truenas_bootenv engine
zectl is being retired in favor of the truenas_bootenv package that
ships with truenas_pylibzfs (companion commit there). The
boot_environment plugin now calls the engine in-process on
middleware's thread-local libzfs handle: query, clone, activate,
destroy and keep all go through it, utils.py with run_zectl_cmd is
deleted, and the boot-time promotion of installer-cloned datasets
uses the engine instead of parsing zfs list -j output.
Mutations serialize on an asyncio lock. A truenas:grub_pending
marker on the boot pool tracks pending menu regenerations and
setup() reconciles it on start. If the menu cannot be written,
activate rolls bootfs back. The boot pool is synced after every
menu write so the change is crash safe.
Re-activating the already-activated boot environment is allowed
again as the retry path after a failed menu regeneration, and
can_activate treats a missing truenas:kernel_version as not
activatable instead of only the literal "-".
[StackColoring] Change TotalStackSize from unsigned to int64_t (#208671)
StackColoring tracks the total size of the stack as `unsigned int`. This
will wrap around, even on 64-bit systems, if the stack is greater than
that resulting in a wrong size. This can happen on both PPC and RISCV64.

resterm: Update to 0.46.3
Improved latency insights
* Displays the current latency alongside a rolling p95.
* Uses the latest 100 requests for more meaningful statistics.
* Shows the 10 most recent requests.
* Highlights slow responses with warning and error colors.
* Handles narrow terminal widths cleanly with ANSI-aware truncation.
[clang-tidy] Support parentheses around subscript operators in readability-redundant-parentheses (#208759)
Subscript operators have the same operator procedure as function calls.
Treat overloaded `()` as built-in operators as a drive-by. I missed this
case when reviewing #192254.
Reject auto combined with type specifiers in C++ (#208552)
Follow-up of https://github.com/llvm/llvm-project/pull/166004
- Diagnose C++ declarations that combine `auto` with another type
specifier, such as `auto int` .
- Preserve C/C23 handling where `auto` can still be interpreted as a
storage-class specifier in valid combinations.
- Fix parser disambiguation so `auto Use = 0` treats `Use` as the
declarator name before type lookup, avoiding ambiguous lookup
regressions.

kvm: Support non-default CPUID leaf
KVM does not always use 0x40000000 as its CPUID base. For example, QEMU
adds a 0x100 offset when nested virtualization is detected and the host
exposes Hyper-V enlightenment hints. To accommodate this behavior,
switch the detection logic to use the CPUID leaf returned by do_cpuid(),
making the implementation more flexible.

[ARM] Use .reloc for weak symbols in PIC mode instead of GOT indirection (#208372)
In ARM ELF PIC mode, weak symbols referenced via the constant pool use a
PC-relative expression like `.long sym-(.LPC+8)`. The assembler eagerly
resolves this when both the symbol and reference are in the same
section, which prevents the linker from overriding a weak definition
with a strong one from another object file.
The previous approach (#198577) forced weak symbols to go through GOT
indirection to avoid this, but that adds an extra load. This patch
instead emits a `.reloc` directive alongside the local PC-relative
expression, forcing the assembler to emit a proper `R_ARM_REL32`
relocation. This lets the linker perform the override without the
runtime cost of a GOT load.
[LLDB] Detect Memory overlapping between AllocateMemory and MemoryInfo
IRMemoryMap estimates a free address range using memory information.
However, the memory returns by AllocateMemory can overlap with the
ranges reported by MemoryInfo (internally backed by PT_VM_ENTRY),
because the kernel is unaware of allocations made during the probing
process.
As a result, two allocatios may silently insert duplicate key for
different objects, leading to intermittent test failure. The issue is
nodeterministic because it depends on the underlying malloc
implementation and ASLR.
Fix this by detecting overlapping allocations after AllocateMemory. If
an overlap is found, fall back to the address-guessing path, which
perform the necessary overlap checks before committing the allocation.
Also, return and print message in IRInterpreter in unsecessful allocation.
