[libc++] Fix shared_ptr(Y*) constraint check on GCC (#199429)
GCC has fixed SFINAEing on `delete` since at least GCC 11, so we can
properly constrain the constructor.
the waitpid() can only return a real pid. none of the error cases can
occur. still, it is good style to check for != -1 before using WIFEXITED().
forgot where i heard about this.
[Mips] Remove mips from omitting the frame pointer for Linux (#199381)
6b1f976858eea5a64f058ca48873be834bd79569 enabled omitting
the frame pointer no matter what OS so remove the now redundancy
with having this on the Linux path.
don't use an uninitialised value for Chrome EC hello
The Chrome EC hello command adds 0x01020304 to the value and returns.
We don't check the result, so this wasn't a problem. With llvm 22
this caused a -Wuninitialized-const-pointer warning.
[llubi] Print out inst location in stack trace (#199430)
This patch appends `file:line number` to each frame in the stack trace.
It would improve the debugging experience.
In all test files, the inputs are supplied via stdin. I think it should
be okay, as I don't need to add wildcards for filenames.
[AMDGPU] Introduce ABI occupancy for object linking
This PR introduces ABI occupancy as the contract used to compile functions under
object linking. The default is derived from the occupancy needed for a 1024
workitem workgroup, can be overridden with `-amdgpu-abi-waves-per-eu`, and can
be overridden per function by `amdgpu-flat-work-group-size` or tightened by an
accepted `amdgpu-waves-per-eu` hint.
The backend emits the selected occupancy in `.amdgpu.info` and uses it to
enforce the object linking register budget.
[clang] preserve exact redeclaration for getTemplateInstantiationPattern
This makes these functions not always return the definition if any.
The few users which depend on this are updated to fetch the definition
themselves.
Also fixes the VarDecl variant returning the queried declaration itself.
[AIX] Re-apply: Remove unsupported AIX native echo option -n by using printf (#199395)
AIX native echo doesn't support the `-n` flag.
Use `printf` instead to ensure the test works across all systems and
making it portable.
The current test fails as follows:
```

net80211: add initial README.md and PROTOCOL.md
* Add top level README.md, linking to in progress and todo items
* Add an 802.11 protocol overview, with todo items - this is designed
to provide a basic introduction to 802.11 for people wishing to work
on net80211 and drivers.
* DEBUG.md - cover the debug API
* DATAPATH_TRANSMIT.md - transmit datapath
* DATAPATH_RECEIVE.md - receive datapath
* PROTOCOL.md - a high level (for values of "high") overview of
the 802.11 protocol and where it intersects with net80211

Add and update some documentation to be picked up by doxygen.

net80211: add some example doxygen inline documents
This isn't supposed to be comprehensive, I want to have examples
for the common doxygen comments:
* describing a struct
* inside a struct - single line before the item
* inside a struct - same line after an item
* inside a struct - multi-line before an item
These build fine with the doxygen build in tools/kerneldoc/subsys/ .

net80211: create ieee80211_ht_check_bar_exceed_retry_count()
Create a function to check if the BAR retry limit has been reached.
Use this in if_ath_tx instead of a hard-coded value.
I've been meaning to do this for a long time.

[ConstantHoisting] Avoid DenseMap reference invalidated by insertion (#199468)
Fix https://reviews.llvm.org/D28962 : DenseMap does not promise to keep
references stable across insertion. This happens to work today because
we don't do bucket eviction.
Pre-populate every node up front.
[clang] implement CWG2064: ignore value dependence for decltype
The 'decltype' for a value-dependent (but non-type-dependent) should be known,
so this patch makes them non-opaque instead.
This patch also implements what's neceessary to allow overloading
on pure differences in instantiation dependence, making `std::void_t`
usable for SFINAE purposes.
This also readds a few test cases from da98651, which was a previous attempt
at resolving CWG2064.
Fixes #8740
Fixes #61818
Fixes #190388
[clang] NFC: add some new test cases (#199467)
These are extracted from my current and future PRs.
They don't have much to do with the PRs themselves except that they were
regressions our test suite missed catching.
