[LLDB] Simplify the hint when po-ing an object with no object descrip… (#200499)
…tion
The current wording of the hint is so long that the output obscures the
output of the command, which can be confusing. By shortening the message
the command output hopefully comes back into the center of attention.
[os_log] Fix a CodeGen crash for non-trivial C++ arguments (#200320)
The earlier fix in commit 8a0d145d90df (#158744) only emitted a hard
error for os_log arguments of record or complex type that took the
VarArgKind::Valid / ValidInCXX11 path in checkFormatExpr. Arguments of
non-trivial C++ class type (non-trivial copy/move ctor or dtor) instead
take the VarArgKind::Undefined path, which only emitted the
-Wnon-pod-varargs warning and let compilation proceed into CodeGen.
There, emitBuiltinOSLogFormat passes the argument expression to
EmitScalarExpr, which requires a scalar type. A non-trivial class
argument is not a scalar, so CodeGen crashes (asserting in
hasScalarEvaluationKind in assertions builds).
Emit the hard error err_format_conversion_argument_type_mismatch on the
Undefined path too, so compilation stops before CodeGen.

graphics/py-pydeck: New port: Python bindings for deck.gl
pydeck is a set of Python bindings for deck.gl, optimized for data
science use cases.
pydeck provides a way to visualize large-scale datasets in Python,
either in Jupyter notebooks or as standalone HTML files.
https://deckgl.readthedocs.io/https://github.com/visgl/deck.gl/pull/10193
This port required by www/py-streamlit 1.57.0.

[X86] Use kmovw, not kmovq, for VK16 copies without BWI (#200337)
`copyPhysReg` selected `KMOVQkk_EVEX` for a `$k -> $k` VK16 copy on a
`+egpr` (APX) subtarget even without BWI, but `KMOVQ` requires BWI. Use
`KMOVW` instead.
This bug was found by a large run of Opus 4.7 looking for bugs in LLVM.
[Support] Add path-based setLastAccessAndModificationTime overload (#199256)
The existing setLastAccessAndModificationTime takes a file descriptor.
Add a const Twine & overload that opens the path internally so callers
no longer need to manage the fd themselves. The new overload accepts
both files and directories: on POSIX, O_RDONLY opens directories and the
existing fd-based implementation accepts a directory fd. On Windows,
FILE_FLAG_BACKUP_SEMANTICS is required to obtain a handle for a
directory.
The path overload pair mirrors the existing (Twine &) / (int FD) shape
used by setPermissions and resize_file.
Disable kbind() and pinsyscalls() for static binaries at the correct
time, which is inside exec_elf_makecmds(). Amusingly, it looks like
these protection mechanisms are not needed because other process state
protects against kbind use since we completed the switch to static pie.
Also any priviledged static binary (which we ship, setuid or daemon) is
not going to contain a pinsyscall or kbind slot in the loaded pinsyscalls
table, so they cannot perform those. Only synthetic binaries with their
own pinsyscalls table could play, but of course they won't run with
priviledge..

netlink/route: extend pre-2.6.19 Linux compat shim to del/getroute
Commit f34aca55adef ("netlink/route: provide pre-2.6.19 Linux compat shim",
2024-06) fixed the partial fix for net/bird2 on the netlink path by mapping the
legacy 8-bit struct rtmsg::rtm_table field onto the modern 32-bit RTA_TABLE
attribute when the latter is absent.
That fix, however, was only applied to rtnl_handle_newroute. The two sibling
handlers: rtnl_handle_delroute and rtnl_handle_getroute were left looking at
attrs.rta_table directly. They are reachable from exactly the same client
(bird, in its netlink scan path), so any FIB number that fits in 8 bits
silently maps to RT_TABLE_UNSPEC in those handlers.

[ExpandIRInsts] Fix sitofp/uitofp to float producing garbage instead of inf (#200291)
[ExpandIRInsts] Fix sitofp/uitofp producing garbage instead of inf
s/uitofp of an integer larger than the max finite floating-point value
should produce inf. This can't happen with e.g. an int32 -> float32
conversion, but can happen for e.g. int256 -> float32.
Before this change we'd produce garbage.
Fixes #189054.

tools/test/stress2/misc: Fix and enable new tests
The previously committed versions of these tests failed to prevent
duplicate file names in the list of files to process, leading to
missing files when a "mv" commando tried to operate on a file that
had already been renamed.
The test for filenames containing UTF-16 surrogate pairs stays
disabled, since the required kernel changes have not been committed,
yet.
Work around unterminated-string-initialization warnings in acpidb
ACPICA 20250807 fixes these warnings by adding nonstring attributes, but
since ACPICA in stable/14 has not been updated for quite some time,
suppress the warning for clang >= 21 instead. Direct commit to
stable/14, since stable/15 and main already have ACPICA 20250807.
[lldb][Darwin] Correct jGetLoadedDynamicLibrariesInfos typeo & fallback (#200515)
Jonas caught that I had a typeo in checking for the
`sizeof_mh_and_loadcmds` key in the `jGetLoadedDynamicLibrariesInfos`
response from debugserver in DyanmicLoaderDarwin. Fix that.
Also I originally picked a fallback value for the mach header + load
commands as a guess. I've sinced looked at a large UI app's binaries and
based on the size of their actual mh+load commands, picked a default
that will read all the data needed in the majority of cases.
