[CodeGen] Rename prologpeilog to prolog-epilog (#207870)
This is primarily to ensure consistenct with the new pass manager where
the name of the pass is already prolog-epilog, which is more consistent
with our existing naming scheme. This is necessary to be able to run
existing llc invocations that explicitly specify prolog-epilog under the
NewPM automatically.

[ORC] Fix reinterpret_cast warning. (#207874)
https://github.com/llvm/llvm-project/pull/206725#issuecomment-4896222897
reported warnings on windows builds due to reinterpret_cast:
warning C4312: 'reinterpret_cast': conversion from 'unsigned int' to
'void *' of greater size
This commit fixes the issue by using ExecutorAddr::toPtr for conversion
instead of reinterpret_cast.
CI: move libclang python byindings tests to main CI
This removes the separate python bindings CI, which run on the GitHub free
runners and take more than one hour to build libclang.
The tests are executed instead in the monolithic pipelines,
whenever clang would be tested.
This is fine in terms of resources because all the dependencies are
built anyway, and the tests themselves take less than one second to
run on the free runners.
[clang-doc] Move Markdown into its own subdirectory (#207856)
Removes the need for PARTIAL_SOURCES_INTENDED by giving clangDocMarkdown
its own directory. Addresses post-merge feedback on #205609.
nfsd: Optionally enable use of M_EXTPG mbufs for read replies
A test site determined that, for a Mellanox NIC which can handle
M_EXTPG mbufs, an improvement of 5-15% for read rate could be
achieved if the read reply was in M_EXTPG mbufs.
A patch that tried to determine if the outbound NIC supported
M_EXTPG mbufs (IFCAP_MEXTPG) did not pass review.
However, it does appear that this can be useful for NFS-over-RDMA.
(Which just happen to use NICs that do support M_EXTPG mbufs.)
As such, this patch enables them is xp_extpg is set to true,
which is never for now, but might be set true for RDMA or
when vfs.nfsd.enable_mextpg is set non-zero. (It is 0 by
default, so this is never enabled by default at this time.)

[libc][RISC-V] Temporarily disable dirent (#207867)
The RISC-V 32 QEMU buildbot is failing due to missing SYS_fcntl, which
is needed for fdopendir. Since that syscall is referenced in the shared
dir code it's easiest to just disable all the dirent functions for now.
[NFC][LLVM][NVPTX] Minor code cleanup in NVVMReflect (#207549)
Use explicit types instead of auto when the type is not obvious. Use
`StringRef` type in the range for loop over `ReflectList`, allowing
additional code cleanups.
[RISCV] Pass structs containing riscv_rvv_vector_bits types using vector registers. (#203601)
The ABI for this isn't documented. The riscv_rvv_vector_bits feature was
copied from aarch_sve_vector_bits which passes the types in vector
registers. At the time I implemented RISC-V I didn't think about struct
arguments so no ABI support was added.
I think it makes sense to pass structs of these types in vector
registers similar to the vls_cc ABI. We already do use vector registers
for these types when the vls_cc ABI is enabled for a function(unclear if
that was intentional), but we should do it unconditionally.
I will work with gcc maintainers to see if they can do the same. In
practice, there probably isn't much compiler mixing with these types.
This patch was heavily assisted by AI, but I've reviewed it and the
changes seem reasonable to me.
[NFC] Fix dxil-dis/waveactiveballot.ll test (#207446)
It looks like #204478 introduced new intrinsic signature verification,
but since it didn't touch any of the HLSL/DXIL related paths the tests
were never run on a runner that has dxil-dis installed on it.

[Attributor] Distinguish COHERENT accesses in addition to exact ones
When we find overlapping accesses, an access is exact when it will hit
the same memory. Otherwise we treated it like an unknown access that
could overwrite any part of the overlapping value. Using size and
alignment we can introduce a new category, COHERENT, which means the
access migth not be at the exact address but if it is affecting the
initial range it will do so with the proper value, e.g., it will not
write part of the range but all or nothing.

[mlir][python] Set a static version in the standalone example pyproject.toml (#207860)
The standalone example's pyproject.toml declares `dynamic = ["version"]` but does not configure a `tool.scikit-build metadata.version.provider`. Newer versions of scikit-build-core reject this combination with:
```
AssertionError: project.version is not specified, must be statically present or tool.scikit-build metadata.version.provider configured when dynamic
```
Just pin a static placeholder version instead of adding a "provider".

[Attributor] AAAddressSpace should use the AA for recursive lookups
If we stripped some values, we can use the AAAddressSpace again for
an optimistic AS value. If we didn't strip any value, we can still use
the TLI.
