[offload] record-replay: only check user-provided grid sizes
The plugins sometimes change what the user provided for num_threads or
num_teams and choose different values for the actual launch. This should
not lead to errors in the replay mechanism. The original clause values
should only be checked if the user specified new values for replay
explicitly.
[mlir] Interface-ify updating starting positions on vector.transfer_*
This commit adds methods to VectorTransferOpInterface that allow
transfer operations to be queried for whether their base memref (or
tensor) and permutation map can be updated in some particular way and
then for performing this update. This is part of a series of changes
designed to make passes like fold-memref-alias-ops more generic,
allowing downstream operations, like IREE's transfer_gather, to
participate in them without needing to duplicate patterns.
In order to test this new method, migrate FoldMemrefAliasOps to use
these methods to fold memref.subview, memref.expand_shape,and
memref.collapse_shape into tranfer_read and transfer_write.
AI note: the tranfer_read / transfer_write patterns, which are taken
from a previous PR, were written with Claude 4.5.

Routing subsystem allows creating new multipath routes by

merge the existing nhgrp with new one.

[VPlan] Remove recipe tracking in VPRecipeBuilder. (NFC) (#195181)
Remove Instruction-to-recipe mapping from RecipeBuilder. The only
remaining user is createInterleaveGroups, where we can easily collect
the mapping.
Add the ability to pass a parent to ValueObjectMemory::Create. (#195155)
Also move the equivalent helper function from ValueObjectConstResult to
ValueObject.h where it more properly belongs.
This patch is necessary if one were to use ValueObjectMemory for a
synthetic child. There aren't any current uses of this sort in lldb,
though there are on the swift fork.

nfscl: Disable use of callbacks for NFSv4.0
The only use for callbacks for NFSv4.0 is delegations
and delegations rarely work well for NFSv4.0 anyhow.
Therefore, this patch disables callbacks for the
NFSv4.0 client. This is the same behavior as
occurred when the nfscbd(8) daemon was not running.
This change allowed a function called nfscl_getmyip()
to be removed from the kernel, which is nice since
maintaining this function was bothersome, due to its
use of routing, etc.

[lldb] Extract DW_OP_convert evaluation (NFC) (#195148)
Move the DW_OP_convert case body to a static helper alongside the other
Evaluate_DW_OP_* helpers. The case did enough work to warrant a small
helper.
[NVPTX] Add commutativity to SETP instructions to enable MachineCSE of inverted predicates
Inverted predicates can be used freely in PTX. If we can invert a
predicate and CSE the generating instruction we can save calculating
the inverse.
Teach the NVPTX commuteInstructionImpl that SETP instructions can be
inverted to allow CSEing with previous SETP that match the inverted
form. This also inverts the branch users of the predicate to maintain
correctness.
Currently only allow the SETP inversion if all users are branches.
Future work can extend this to sel and not instructions.

[lldb] Extract DW_OP_piece evaluation into a helper (NFC) (#195142)
The DW_OP_piece case was the deepest-nested body in
DWARFExpression::Evaluate, with a switch inside a switch. Move it to a

for Evaluate_DW_OP_deref_size and Evaluate_DW_OP_entry_value.
Add zvol block cloning test
zvol block cloning depends on custom TrueNAS kernel patches that add
blkdev_copy_offload() to the block layer. The ZFS code path is gated
behind HAVE_BLKDEV_COPY_OFFLOAD and compiles out on stock kernels, and
there is no existing automated coverage of this path.
The test creates two zvols, issues copy_file_range, and asserts via zdb
that exactly 64 L0 blocks share identical DVAs between src and dst.
Identical DVAs prove the destination references the source's blocks
rather than holding an independent copy.
dhclient: Improve server and filename validation
* Don't iterate over each string three times; once is enough.
* Reject control characters (anything below space) in addition to the
double quote and backslash.
* If an unsafe character is encountered, discard the string instead of
rejecting the entire lease.
* If backslashes are encountered in the file name option, convert them
to forward slashes instead of rejecting the option.
* Tweak the warning messages a bit. Looking through the rest of the
code, it seems to me that notes generally end with a period while
warnings generally don't.

md5: Encode non-printable filenames
Encode filenames in the VIS_CSTYLE | VIS_OCTAL style regardless of
output mode. When reading filenames from a checksum file, attempt to
decode them, and use the decoded name unless the decoded name does not
exist but the undecoded one does.
This breaks compatibility with GNU coreutils, which unfortunately uses
a non-reversible encoding when outputting filenames containing
non-printable characters.
While here, drop a sentence about preimage attacks against MD5 and SHA1
from the manual page, as I no longer trust it to be true.
