[lldb] Define breakpoint location "." to mean the location(s) at which the current thread is stopped (#194272)
Adds `.` as a new `breakpt-id` syntax. Users can specify `.` to mean the breakpoint
location(s) that caused the current thread to stop.
I selected `.` to mean the current breakpoint locations for two reasons. In a shells,
period means <ins>current</ins> directory. In prose, a period is a <ins>stop</ins>.
My workflow often starts with multiple breakpoint locations, such as with regex
breakpoints, or basename breakpoints for overloaded/overridden names. As locations are
hit, I realize which locations are no longer needed. This new syntax makes it quick and
easy to disable the currently stopped location(s).
Another use case for this is to quickly repeat commands for the current location:
``` break com add -o 'p someVar' . ```

Remove truenas-initrd.py and now dead dependencies
This commit removes local copy of truenas-initrd.py script, which
is now provided by https://github.com/truenas/upgrade_pyutils.
Since this script was the only consumer of the rootfs util to
toggle readonly property on filesystem it is also removed.

[AMDGPU][MIRFormatter] Printer & parser for S_WAITCNT human-readable mask (#193895)
This patch implements a printer and parser for the S_WAITCNT mask. It
prints the mask in a human-readable format, showing the counter values
like `Vmcnt_<NUM>_Expcnt_<NUM>_Lgkmcnt_<NUM>`.
The format matches the printing style of S_WAITCNT_DEPCTR. For example:
```
S_WAITCNT .Vmcnt_0_Expcnt_0_Lgkmcnt_0
S_WAITCNT .Expcnt_0
S_WAITCNT .AllOff
```
Counters at their maximum value (meaning "don't wait") are omitted. When
all counters are at max, `.AllOff` is printed.

[HLSL] Make load methods take const attribute (#193858)
Previously, HLSL shaders that declare a local resource const, cannot use
the `Load` method, since it is not attributed with const.
Load does not change a resource, it is a read-only operation, so the
method should be marked const.
This PR changes the methods so that they are marked const.

[clang][NFC] Mark CWG2810 as implemented and add a test (#194683)
CWG2810 (https://cplusplus.github.io/CWG/issues/2810.html) just removes
some wording that could be misinterpreted as saying "a compiler must not
emit any warnings in uninstantiated templates". Clang has never
misinterpreted it that way, so we don't need to do anything here.
[TableGen] Use guarded assert in constexpr functions
The constexpr functions in question take a scoped enum as an argument
and a switch statement returns a value for each value of the enum.
These are all legal statements in a constexpr function in C++14.
Under constexpr rules, the evaluation of a constexpr function cannot
lead to an evaluation of any prohibited forms of expressions. An
evaluation of the functions being discussed with a valid argument
will terminate at the switch, and an code that follows will not be
evaluated.
Using "llvm_unreachable" after the switch should be ok as long as
the expansion of the llvm_unreachable macro does not contain any
statements not allowed to appear in a constexpr function.
At the same time, GCC before v9 did not tolerate any unguarded calls
to non-constexpr functions after the switch.
To avoid using "llvm_unreachable", which can have multiple expansions,

[LLDB] Add module hook implementation (#185465)
Introduce a unified target hook command system for LLDB that handles
multiple target lifecycle events (module load, module unload, process
stop) through a single Hook class.
The existing target stop-hook commands remain unchanged for now, meaning
stop-hooks can now be created through either target stop-hook add or
target hook add -S.
A future follow-up can alias target stop-hook to the unified system to
consolidate the two paths.
New commands:
- target hook add [-o cmd] [-P class] [-u] [-S] - create a hook (fires
on module load by default, optionally on unload/stop)
- target hook add-filter [filter-opts] <hook-id> - attach stop-event
filters (shlib, function, file/line, thread) to an existing hook
- target hook list / delete / enable / disable - manage hooks
- target hook {enable,disable} {module-loaded|module-unloaded|stop-hook}

[OpenMP] Fix use of uninitialized Dl_info when dladdr fails in ompd_init (#193643)
When dladdr() fails, dl_info is left uninitialized. The code printed the
error but then fell through to unconditionally call
strrchr(dl_info.dli_fname, '/'), accessing an uninitialized pointer --
typically NULL on the stack -- causing a SIGSEGV.
Fix by turning the second 'if' into 'else if', so the path-extraction
block is only reached when dladdr() succeeded and dl_info is valid.

[CIR] Implement return for void lambda with static invoker (#194704)

The same semantic checks for the context selectors apply here as in the

[libc] implement recursive mutex and fix wrong initializer (#193992)
Fix #193892.
This is found during libc++ bringing up process. This patch:
- implement recursive mutex support for real.
- fix the issue that pthread mutex initializer and public mutex
interface misalign with internal representation. this was the root cause
that hangs the libc++ test as padding bytes effectively pollute the
futex state if default initializer was used.
- additionally, we changed the field to bitfield to allow encoding more
data. (e.g. the error checking flag that is not yet added). timed bit is
removed as we always support it anyway. PI bit is added instead.
ctld: kernel-sourced portal groups are not dummies
The current and historical versions of ctld would flag our initial set
of kernel ports as dummies, because their portal groups were empty since
portals come from the configuration on-disk.
As a result, we would never try to remove a kernel port at startup that
didn't exist in the configuration (possibly a feature if you wanted
concurrent ctld(8)), and we would always try to port->kernel_add() on
ports in the configuration (even if they actually did have an existing
kernel port).
Flag these portal groups as kernel groups so that we avoid trying to add
ports that already exist. It may be the case that the kernel_remove()
loop in conf::apply() needs to do something other than the current
`oldport->is_dummy()` to avoid removing ports that it isn't supposed to
be managing, but that wuld also seem to apply to LUNs that would be
removed today.
