[mlir][arith] Add `arith.convertf` op (#188041)
There are multiple FP types with the same bitwidth. Neither `extf` nor
`truncf` can be used in that case. Add a new `arith.convertf` op that
can be used in such cases. The op is modeled after `arith.truncf`. Also
add a lowering to LLVM.

libclc: Force assuming fast float fma for AMDGPU (#188245)
Currently the build uses the default dummy target, which assumes
FMA is slow. Force this to assume fast fma, which is the case on
any remotely new hardware. In the future if we want better support
for older targets, there should be a separate build of the math
functions for the slow fma case.
[X86] Fix widening for strict_fmin/fmax (#188286)
I believe that widening these with undef is not correct, because the
undef values might be picked as sNaN and then trap.
[DA] Fix the Weak Crossing SIV test when Coeff and Delta are zero (#188203)
The Weak Zero SIV test concluded that there is a dependency only in the
`=`-direction when `Delta` is zero. This is incorrect, because the
coefficients of the addrecs might be zero, in which case the dependency
should have all directions. This patch adds non-zero check for the
coefficient to address the issue.
[lldb] Print correct thread plan in logging code of Thread::ShouldReportRun (#188198)
This code accesses the completed thread plan (even if it's private one).
However, the logging code does not pass `skip_private=false` and instead
accesses only the public completed thread plan. In case there is no
public thread plan, the logging code could also crash.
This is just some minor refactoring that ensures we use the same thread
plan in the logging code.
[ARM] Fix incorrect post increment from Or (#188036)
If a Or is detected by findPointerConstIncrement but not by
getPointerConstIncrement it could use an invalid increment for the
offset. Protect against cases where getPointerConstIncrement cannot
return a valid offset.
Fixes #185677

libclc: Unify fast FMA controls (#188244)
This was defined in multiple places with different names. Consolidate
on one, with a gentype wrapper for it. Also set the value based on the
standard FP_FAST_FMA* macros.
[MLIR][XeGPU][TransformOps] Remove obsolete transform ops (#187561)
Cleaning up XeGPU transform ops. Now that XeGPU layout propagation
works, it is sufficient to set the layouts for anchor ops (e.g.
load/store/dpas ops) only.
Changes:
* Remove `xegpu.get_desc_op` and `xegpu.set_desc_layout`. Users should
not change the layout of descriptor op's return value anymore.
* Add `xegpu.get_load_op(value)` that finds either `xegpu.load_nd` or
`xegpu.load` op in the value's producer chain. This is a useful utility
as load ops often need to be annotated with a layout.
* The generic `xegpu.set_op_layout_attr(op, ...)` is now replaced by
`xegpu.set_anchor_layout(op, ...)` that only sets layout attribute of
anchor ops. Raises an error if the given op does not support anchor
layouts.
* `xegpu.insert_prefetch` takes a load op handle instead of a value.
AMDGPU: Implememt memsize forms of isLoadFromStackSlot/isStoreToStackSlot (#188264)
Requested in #182673, though I'm not sure why this needs to be pushed
into targets. The size can be taken from the machine mem operand
generically.

[libc] Add utimensat syscall wrapper and entrypoint (#188347)
Implemented the utimensat syscall for Linux and added the entrypoint to
sys/stat.h.
* Added utimensat syscall wrapper to OSUtil
* Updated utimes to use the utimensat wrapper
* Added utimensat unit tests to sys/stat
* Configured entrypoints for x86_64, riscv, and aarch64
firewall: adjust sort order in networks and aliases; closes #10022 #10031
While here also switch to use the cached model exclusively and change the
formatting of address/network shortcuts actually calling them "network".
[OFFLOAD][L0] Add support to run ctor/dtor code (#187510)
This PR adds support in the Level Zero plugin to execute
constructors/destructors on the device code. As spirv-link has some
limitations, it mimics the CUDA plugin behavior where the RTL constructs
the device side tables before invoking the kernel that will execute
them.
The kernel and other necessary symbols to create the device tables are
created by the SPIRVCtorDtorLowering pass to be added in #187509
[ORC] Move DylibManager impl out of SelfExecutorProcessControl. (#188417)
SelfExecutorProcessControl no longer implements DylibManager. Instead a
private inner class, InProcessDylibManager, is used to implement this
interface. This change should not affect the behavior of
SelfExecutorProcessControl from the perspective of API clients.
This is a step towards decoupling ExecutorProcessControl implementations
from other interfaces.
AMDGPU: Simplify placeholder replacement in AMDGPUPromoteAlloca (#188202)
If `promoteAllocaUserToVector` returns the placeholder, it means the
instruction does not actually modify the alloca. we don't need to add
the placeholder as block available value for correctness. Instructions
appear afterwards in the the same block could still get the placeholder
as source value through GetCurVal() call. Instructions in other block
which access the alloca will be set up later when we really do
placeholder replacement.
This help simplify the placeholder replacement logic.
[libc][docs][NFC] Expand entrypoints technical reference (#4) (#188255)
Expanded entrypoints.rst with details about definitions, registration
rules, and the lifecycle of an entrypoint.
Updated multiple documents to remove redundant technical details and
link to the centralized entrypoints reference:
- libc/docs/dev/cmake_build_rules.rst
- libc/docs/dev/implementation_standard.rst
- libc/docs/porting.rst
- libc/docs/dev/source_tree_layout.rst
