* Fixed the simulator ports so they compile when TX_MISRA_ENABLE is defined
_tx_thread_stack_build() in the four simulator ports converts the fake stack
pointer through TX_POINTER_TO_ALIGN_TYPE_CONVERT and
TX_ALIGN_TYPE_TO_POINTER_CONVERT. tx_api.h defines both macros only in the
non-MISRA branch of its #ifdef TX_MISRA_ENABLE, so with that macro defined the two
names are undeclared and none of the four files compiles.
Reproduced with:
gcc -m32 -c -DTX_MISRA_ENABLE -I common/inc -I ports/linux/gnu/inc \
ports/linux/gnu/src/tx_thread_stack_build.c -o /dev/null
which reports both names as implicit declarations and then an int to pointer
assignment. The same command without the define compiles cleanly.
No build configuration under test/tx/cmake or test/smp/cmake defines
TX_MISRA_ENABLE, so CI never compiles these files in that mode. It surfaced on a
branch that carries such a configuration.
The conversions are now written inline, which is what the non-MISRA macros expand
to and what the surrounding port code already does, including the line this
replaced.
The alternative would be the idiom common/src/tx_thread_create.c uses for the same
conversion: an explicit #ifdef selecting the ULONG pair under MISRA. That is not
equivalent here. On __x86_64__ this port defines ULONG as unsigned int and
ALIGN_TYPE as unsigned long long, so a pointer round-tripped through the ULONG pair
loses its top 32 bits. Writing the conversion inline keeps one form that is correct
in both modes and on both widths.
Verified by compiling the Linux port with and without TX_MISRA_ENABLE, both clean.

* Fixed the same MISRA build break in the SMP and module manager thread create
_tx_thread_create() in common_smp and _txm_module_manager_thread_create() convert the
thread's stack start through TX_POINTER_TO_ALIGN_TYPE_CONVERT and
TX_ALIGN_TYPE_TO_POINTER_CONVERT with no conditional at all. tx_api.h defines both
macros only in the non-MISRA branch, so with TX_MISRA_ENABLE and
TX_ENABLE_STACK_CHECKING both defined neither file compiles. It is the same defect as
the simulator ports in the previous commit, in two more files.
Reproduced with:
gcc -c -DTX_MISRA_ENABLE -DTX_ENABLE_STACK_CHECKING \
-I common_smp/inc -I ports_smp/linux/gnu/inc \
common_smp/src/tx_thread_create.c -o /dev/null
which reports both names as implicit declarations. Both files now compile with and
without TX_MISRA_ENABLE.
The conversions are written inline for the same reason as the ports: the #ifdef idiom
that common/src/tx_thread_create.c uses selects the ULONG pair under MISRA, which
truncates a pointer wherever ALIGN_TYPE is wider than ULONG. That is reported
separately.
Verified: the SMP regression suite passes 117 of 117, and the ThreadX suite still
builds.

The per-edit disclosure named the product and model, so every agent and every
model version appended another line. 74 files carried two to four of them, and
the same five products had accumulated 13 spellings -- Copilot against GitHub
Copilot, Claude Sonnet 4.6 against claude-sonnet-4.6, four spellings of Codex.
Twenty assembly lines carried a doubled comment marker, `; //` or `@ //`.
Every file now carries exactly one line, fixed text naming no product:
Portions of this file were generated with AI assistance.
It is written with the comment character that file already uses, so the `;`
and `@` assembly files keep theirs and the doubled markers are gone. Precise
attribution stays on the commit, where the Assisted-by trailer is per-change,
dated and attached to the diff it describes. A header line cannot hold that
record honestly, because the code it names gets rewritten and the line stays.
A file-level flag answers whether; the history answers who.
Comment-only. 455 files, 455 insertions and 574 deletions: every removed line
was a disclosure line, every added line is the fixed text, and no file is left
with zero or with more than one. `scripts/check_ports.sh` passes, including the
reproducibility check that would catch a ports_arch master and its generated
copies drifting apart. Recompiled against dev, every file that builds without a
vendor toolchain gives a byte-identical object: 19 of 19 C files under common,
100 of 100 GNU assembly files, and all 16 assemblable files whose comment
marker changed. The 10 remaining marker changes are ac5 and IAR sources where
`;` already started the comment and only the redundant `//` was removed.

* Marked every published ThreadX include directory as SYSTEM so applications no longer get warnings from ThreadX headers
Commit 8c3c08f added the SYSTEM keyword to the target_include_directories
call in common/CMakeLists.txt, but the same call in every port, in the
SMP common directory's consumers, in the POSIX and FreeRTOS compatibility
layers, and for the generated tx_user.h directory was left unchanged.
A consumer building with a strict warning set therefore still saw
diagnostics coming from tx_port.h and from the compatibility layer
headers, which is exactly what the original change set out to avoid.
Added the SYSTEM keyword to all of those calls so CMake emits -isystem
rather than -I for every directory holding a ThreadX public header. The
ARMv7-M, ARMv8-M, ARMv7-A and ARMv8-A architecture sources under
ports_arch were updated alongside the ports they generate, keeping the
two in step.
Directories that are PRIVATE to an example or test build were left as
they are, since nothing is published from them.

* Stopped apt-get update being a gate it was never meant to be
apt-get update fails if any configured repository serves a bad index,
including ones this project never reads. The GitHub runner image carries
Google's and Microsoft's apt repositories, and a Hash Sum mismatch from
Google's, their CDN caught mid-publish with the index and the Release
file eight hours apart, failed all three attempts and turned a run red
over a browser nobody was installing.
Made a failed update warn and carry on, leaving apt-get install as the
gate. Nothing is weakened by that: the install still exits on a package
it cannot find, so an unreachable archive still stops the script, one
step later and naming the package it could not get, which is a better
diagnostic than a hash mismatch in a repository nobody asked for.
Disabling third-party sources before updating would keep the update
strict, but this script also runs on a contributor's own machine, and
rewriting someone's apt configuration to suit CI would be worse than
tolerating a stale index for an archive we do not read.

The Linux, Win32 and Win64 simulation ports build a fake initial stack
pointer by subtracting a fixed 8 bytes from tx_thread_stack_end. That
field addresses the last byte of the thread's stack area, so it is one
less than an aligned address and the resulting pointer is misaligned by
construction, no matter how well aligned the stack the application
supplied was.
Two ULONG accesses then use that pointer. _tx_thread_stack_build() itself
clears the word below it, and _tx_thread_create() copies it into
tx_thread_stack_highest_ptr, which TX_THREAD_STACK_CHECK dereferences on
every suspend and resume when TX_ENABLE_STACK_CHECKING is defined. Both
are undefined behaviour. They happen to work on x86 but are reported by
GCC's undefined behaviour sanitizer, and would fault on a host that
requires natural alignment.
The fake stack pointer is now rounded down to a ULONG boundary, which
leaves it inside the stack area and makes both accesses aligned.
Verified by building the Linux port with -fsanitize=undefined and
running the demo: the two reported diagnostics are produced before the
change and neither appears after it. The tx and smp regression suites
pass, 98 and 114 tests respectively.

The CMake build produced libthreadx.a and nothing else, so trying ThreadX on
Linux meant using the Makefile beside the port instead. Build the demo the
Makefile builds, for the linux port and its SMP counterpart.
The target is behind an option that defaults off, so an ordinary build is
unchanged and still produces just the library. -DTHREADX_SAMPLE=ON adds it:
cmake -S . -B build -DTHREADX_ARCH=linux -DTHREADX_TOOLCHAIN=gnu \
-DTHREADX_SAMPLE=ON
cmake --build build --target sample_threadx
The include path uses TX_COMMON_DIR rather than naming common or common_smp,
since the top level already resolves which of the two applies.
Verified by building and running both variants. Non-SMP prints
**** ThreadX Linux Demonstration **** (c) 1996-2020 Microsoft Corporation
and SMP prints the SMP banner, both with the demo's thread counters advancing. A
default configure with no THREADX_SAMPLE has no sample_threadx target and still
produces libthreadx.a, so nothing existing moves.
Derived from the two example_build files in #404 by Yanfeng Liu, which had the
same goal. That change also rewrote the top level's SMP selection, added
common_smp/CMakeLists.txt and added ports_smp/linux/gnu/CMakeLists.txt; all three
have since arrived on dev by other routes, so only the sample targets were still
missing. The include path needed adjusting because the original depended on
THREADX_SMP being a string suffix, which it no longer is.
