[AMDGPU] Add MC tests for scalar operands for packed fp32 instructions (#193866)
To remind that a SGPR is acceptable only if op_sel = op_sel_hi = 0 for that operand.
Note that the default is op_sel = 0 and op_sel_hi = 1.
[clangd] [C++20] [Modules] Introduce persistent cache for clangd built module file (#193883)
Currently clangd lacks a persistent cache for clangd built module file.
It implies that every time a new clangd process starts, or a user close
all tabs and opening all a new tab. Clangd will build all the module
files required. This is a slow process. Especially, the building happens
in the building thread for the opening tab. That is, if the user only
opens a single tab, clangd needs to build all the module file in a
single thread. This is very slow in practice.
As clangd is basically a wrapper for clang, we can't do nothing to speed
the building process actually and the only thing we can do is to
introduce a better cache mechanism.
So everytime the user opens a new tab, now clangd won't try to build all
the needed module file at first but try to see if these module files are
already built and up-to-date. So clangd can try to avoid a lot of time
to rebuilding the same thing.

pseries/llan: call init when ioctl sets interface UP
This should fix dhcp on an unitialized interface. This solution was
found while comparing against another driver, SIOCSIFFLAGS is used by
dhclient to force the interface up before it has an IP address.
However, all setup work is done in llan_init(), so the interface would
not be enabled if configured via only the SIOCSIFFLAGS ioctl. By
running llan_init() when the interface is forced up via SIOCSIFFLAGS,
the interface is initialized properly.

[clang-scan-deps] Fixes an assertion in clang-scan-deps (#193619)
Please see ticket #191921 for detailed description of the issue and a reproducer.
clang-scan-deps crashes with an assertion failure if a compile_commands.json entry contains a depfile path (-MF) whose parent directory does not exist.
The fix is made so that clang-scan-deps tool create the directory if it doesn't exist and finish execution without failing.
[RISCV] Remove codegen for vp_fneg, vp_fma. NFC (#193214)
Part of the work to remove trivial VP intrinsics from the RISC-V
backend, see
https://discourse.llvm.org/t/rfc-remove-codegen-support-for-trivial-vp-intrinsics-in-the-risc-v-backend/87999
We began expanding these nodes in #190589 since vp_fadd/vp_fmul/vp_fsub
could be combined into them. Now that these intrinsics are expanded too,
the lowering for these is dead and can be removed.
[VPlan] Fold lhs | (headermask && rhs) -> vp.merge rhs, true, lhs, evl (#193511)

folding.

ping6: treat setsockopt failures as fatal
ping6 needs IPV6_RECVPKTINFO and IPV6_RECVHOPLIMIT to process
incoming replies. When these options fail, replies are silently
dropped and ping6 appears to hang. Use err(3) instead of warn(3)
so the user gets a clear error and immediate exit.

[OpenCL] Diagnose error for zero-length array (#193163)
OpenCL C is based on C99 and C11, which don't support zero-length array.
Update clang/docs/ReleaseNotes.rst for potential breaking change.
[Clang][CodeGen] Fix sret lifetime marker AS mismatch after #186275 (#193850)
After #186275, the sret address space can differ from the alloca address
space (e.g., AS 0 vs AS 5 on AMDGPU). In CGCall.cpp EmitCall(), when a
discarded-value sret temporary is created, SRetPtr is allocated in the
alloca AS and a lifetime.start is emitted. The pointer is then
addrspacecast'd to match the sret AS, but the CallLifetimeEnd cleanup
was using the addrspacecast'd pointer, triggering an assertion in
EmitLifetimeEnd ("Pointer should be in alloca address space").
Saves the original alloca pointer before the addrspacecast and uses it
for the lifetime-end cleanup.

[libclc] Allow testing unresolved symbols on multiple libraries (#193647)
Our downstream generates multiple libraries for a single target. This
change allows testing multiple libraries.
[libclc][CMake] Remove CMAKE_C_COMPILER_ID check (#186717)
When LLVM_TARGETS_TO_BUILD does not contain the host target, runtime
build can not identify a compatible target triple for the host compiler.
CMAKE_C_COMPILER is set to clang, and CMAKE_C_COMPILER_ID is empty
although the compiler is functional.
Remove CMAKE_C_COMPILER_ID check. CMakeTestCLCCompiler.cmake already
provides a real functional guard.
This change ensures valid configurations can proceed, e.g.:
LLVM_TARGETS_TO_BUILD=AMDGPU;
RUNTIMES_amdgcn-amd-amdhsa-llvm_LLVM_ENABLE_RUNTIMES=libclc;
LLVM_RUNTIME_TARGETS="amdgcn-amd-amdhsa-llvm".
Note CMAKE_C_COMPILER_WORKS is always true after `project(Runtimes C CXX
ASM)` in runtimes/CMakeLists.txt.
