tests/kernel/t_time_arith.c: update for the recent kernel change
the test updates in the recent change was for some reasons incomplete.
("itimer_transition: do not keep it_value unchanged after firing the event")
https://mail-index.netbsd.org/source-changes/2026/03/17/msg161046.html
this commit updates the rest of tests.
tested with a full build and then the following command:
```
# chroot destdir
# cd /usr/tests/kernel
# atf-run t_time_arith > /dev/null
# echo $?
0

```
test failures are pointed out by Taylor R Campbell

[analyzer] Fix logic in CallEvent::getReturnValueUnderConstruction (#187020)
The `CallEvent` has data members that store the `LocationContext` and
the `CFGElementRef` (i.e. `CFGBlock` + index of statement within that
block); but the method `getReturnValueUnderConstruction` ignored these
and used the currently analyzed `LocationContext` and `CFGBlock` instead
of them.
This was logically incorrect and would have caused problems if the
`CallEvent` was used later when the "currently analyzed" things are
different. However, the lit tests do pass even if I assert that the
currently analyzed `LocationContext` and `CFGBlock` is the same as the
ones saved in the `CallEvent`, so I'm pretty sure that there was no
actual problem caused by this bad logic and this commit won't cause
functional changes.
I also evaluated this change on a set of open source projects (postgres,
tinyxml2, libwebm, xerces, bitcoin, protobuf, qtbase, contour, openrct2)
and validated that it doesn't change the results of the analysis.
[CGP][PAC] Flip PHI and blends when all immediate modifiers are the same
GVN PRE, SimplifyCFG and possibly other passes may hoist the call to
`@llvm.ptrauth.blend` intrinsic, introducing multiple duplicate call
instructions hidden behind a PHI node. This prevents the instruction
selector from generating safer code by absorbing the address and
immediate modifiers into separate operands of AUT, PAC, etc. pseudo
instruction.
This patch makes CodeGenPrepare pass detect when discriminator is
computed as a PHI node with all incoming values being blends with the
same immediate modifier. Each such discriminator value is replaced by a
single blend, whose address argument is computed by a PHI node.
[clang-tidy] Fix alphabetical order check for multiline doc entries and whitespace handling (#186950)
The `check_alphabetical_order.py` script previously only scanned the
first line of each bullet point in `ReleaseNotes.rst`, causing sorting
failures when a `:doc:` tag was split across multiple lines.
Also, when it is sorting the last entry of a section, the script will
insert an unnecessary whitespace.
This PR fixes these two problems.
update to libvpx-1.16.0, from Brad
I've tested building all dependents except chromium with this,
tried building chromium 3 times and it failed for js-related reasons
so hopefully it will do better in bulks!
