_tx_thread_relinquish walks the ready list at the relinquishing thread's priority for a
thread to hand its core to. When the walk reaches one it cannot place, carrying
preemption-threshold or excluded from that thread's mapped core, it sets the rebalance
flag and breaks. That exit falls into the block concluding no other thread is ready,
which is not what the walk found, and that block sets the finished flag. The rebalance
at the end of the function is guarded on that flag, so it never runs.

Every rebalance requested from inside the walk is discarded, because that exit always
reaches the block first. A ready thread behind the obstacle then never reaches a core
while the others hold them and relinquish to each other. The tick keeps arriving, so it
is a livelock rather than a deadlock.

The early return now applies only when no rebalance was requested, which lets control
reach the rebalance path the other three request sites already use.

threadx_smp_relinquish_rebalance_test fills the cores with threads of one priority
relinquishing in a loop, places a thread excluded from every core behind them and a
runnable thread behind that, and fails if the runnable one has not run within 100 ticks.
It fails 3 of 3 before this change and passes 5 of 5 after. Instrumenting a passing run
of threadx_thread_relinquish_test counted 12 rebalance requests from the walk against 4
performed, all 4 from sites outside it. 109/109 in all eight configurations, twice from
clean.

<title>Restored the random stack fill value cleared during thread creation (#732)</title>

Fixes #723

With `TX_ENABLE_STACK_CHECKING` and `TX_ENABLE_RANDOM_NUMBER_STACK_FILLING` both
enabled, `_tx_thread_create` picked a random byte, stored it in
`tx_thread_stack_fill_value`, filled the stack with it -- and then cleared the
whole control block with `TX_MEMSET`. The stack held the pattern while the
control block claimed zero, so `TX_THREAD_STACK_CHECK` and
`_tx_thread_stack_analyze` compared against the wrong value for the entire life
of the thread.

The value is now computed into a local and written back after the clear. The
clear stays where it is, because the module manager's error checking walks the
created list before the control block may be touched.

Fixed in `common/src/tx_thread_create.c`, `common_smp/src/tx_thread_create.c`
and `txm_module_manager_thread_create.c`, where it additionally left a user-mode
module thread's kernel stack filled with zeros.

`threadx_thread_stack_fill_value_test` creates sixteen unstarted threads and
checks each control block against the pattern in its stack, tolerating a random
zero byte without letting that hide the defect. Added to both suites: `ERROR #3`
on `dev` in `stack_checking_rand_fill_build`, green with the fix. Five tx
configurations at 104 tests, five SMP at 117, and all three sources clean under
`-Wall -Wextra` across every combination of the four stack-filling switches.

<title>Refused thread delete and reset while an exit transition is in progress (#724)</title>

<id>urn:sha1:70741198e9f6831acf52257913d1bb9c7a5a2720</id>
<content type='text'>
_tx_thread_shell_entry and _tx_thread_terminate both publish a thread's
terminal state -- TX_COMPLETED or TX_TERMINATED -- and then call that
thread's exit notification callback, before the thread has been detached
from the ready list and before either service has finished with the pointer
it holds to the control block. That terminal state is exactly the state
_tx_thread_delete and _tx_thread_reset accept as authorization to
invalidate or rebuild the control block, and neither service tested whether
the transition producing it had finished.

A callback could therefore delete the thread it was called for -- and then
lawfully recreate it over the same memory, since delete exists to permit
that -- while the scheduler was still linked to the old incarnation.
tx_thread_create zeroes the whole control block and can auto-start the new
one, so the old priority list is left heading at a block whose own priority
field names a different list, with the old priority's map bit set behind
nothing. Alternatively a callback could reset a terminated thread, which
moves it out of the terminal state, and then resume it: the interrupted-
suspension logic in _tx_thread_system_resume refuses to void a suspension
only while the state is still terminal, so with the reset allowed first the
resume clears the suspending flag and restores TX_READY, the outer service
then finds the flag clear and skips the removal, and tx_thread_terminate
returns TX_SUCCESS for a thread that is runnable again.

Interrupt masking does not close the window, because the kernel restores
the prior posture before invoking the callback deliberately. On SMP
TX_RESTORE also releases the global protection, so the target can be
executing on another core while its callback runs -- and a reset there
memsets the stack a live core is running on. On the Linux, Win32 and Win64
host simulation ports the consequence is more immediate than corruption:
TX_THREAD_DELETE_PORT_COMPLETION cancels and joins the host thread backing
the deleted thread, so a callback-side delete of the completing thread
destroys the host thread the callback is running on.

The fix marks the transition and has the two services refuse a marked
target, returning the errors they already document, TX_DELETE_ERROR and
TX_NOT_DONE. The refusal is transient and the same call succeeds once the
transition has completed, so no documented lifecycle is lost; and it is in
the core services rather than the _txe_ wrappers, so disabling error
checking cannot disable it. Refusing the reset is also what closes the
resume path, without touching _tx_thread_system_resume: its existing
terminal-state test is sufficient once nothing can turn the terminal state
into TX_SUSPENDED from inside the window.

tx_thread_suspending is the marker, rather than a new control-block field.
It already means "a suspension is in progress" and is already true across
the callback in the two interruptable paths, so no field is added, the
public structure is unchanged, and sizeof(TX_THREAD) is unchanged --
which matters, because the Module Manager's object handling depends on the
sizes of the control blocks. Widening its lifetime was checked against
every reader rather than assumed. There are four: two in
_tx_thread_system_suspend and two in _tx_thread_system_resume. In every
window this change widens, the state is TX_COMPLETED or TX_TERMINATED, and
both resume readers already refuse to void a suspension for exactly those
two states, so their behaviour is unchanged; and no suspension routine is
called on the target in those windows, so the suspend readers never see
them. No suspension-initiating service can set the marker again inside a
window either: every one of them acts on a thread that is ready or
suspended.

Three sites needed changing beyond the two refusals, and the shape of each
was decided by where the marker can safely be cleared:

  - The non-ready branch of _tx_thread_terminate cleared the marker before
    the terminated extension and the callback, which is what left them free
    to act on a control block the service still had mutex-release
    processing to do against. The clear moves to the common tail, after the
    last dereference of the target, and becomes the single clear site for
    the whole service. In the interruptable ready branch the flag is
    already false there, because _tx_thread_system_suspend cleared it when
    it detached the thread, so the tail store is a second store of a value
    the flag already holds -- cheaper than testing for it, and it keeps one
    clear site.

  - Under TX_NOT_INTERRUPTABLE neither path set the marker at all, because
    that configuration does not use the interruptable suspension path that
    sets it. Both now set it before the callback. Interrupts being disabled
    there does not help: the callback is reached by a direct call.

  - In the TX_NOT_INTERRUPTABLE completion path the marker is cleared
    before _tx_thread_system_ni_suspend rather than after it. That call
    returns to the scheduler for a thread that is the current thread, which
    a completing thread is, and does not come back; clearing afterwards
    would leave a normally completed thread marked for ever and therefore
    permanently undeletable. Nothing is lost by clearing early there,
    because everything from that point to the detachment runs with
    interrupts disabled and calls no application code.

The change is the same change twice. All four files are byte-for-byte
identical between common and common_smp at this commit and stay so after
it, so common_smp was written by copying rather than by repeating the
edits. tx_thread_system_suspend.c and tx_thread_system_resume.c, which do
differ between the kernels, are deliberately untouched.

Tests. The in-tree regression test goes to both trees and is byte-for-byte
identical between them. It drives seven scenarios: terminating a ready
non-current target with two peers ready at the same priority, with the
callback attempting the delete and recreating the block if it succeeded;
the same with the callback attempting the reset and then the resume;
terminating a target suspended on a semaphore while owning a mutex, which
is the non-ready branch; natural completion alone at its priority,
including the safe post-completion reset, terminate, delete and recreate at
another priority; self termination; a benign callback, whose notification
count and ordering are unchanged; and the state and boundary cases, where
the new refusal must not fire.

It measures rather than describes. The callback records the published
state, the marker, and the status of every lifecycle service it can reach,
calling the core service as well as the wrapper wherever a refusal is
expected. A snapshot taken under interrupt lockout -- which is the global
SMP protection on an SMP port -- checks that every ready list agrees with
the control blocks it heads, that the priority map agrees with the lists,
and that each execute pointer is a member of the list its own priority
field names. Every walk is bounded, so a corrupted ring costs an assertion
and not a hang, and no test in the suite can hang. Expectations are counted
inside a scenario and gated between scenarios, so a failing kernel reports
how much it failed by without being driven further into its own
corruption.

The consequences are demonstrated from the terminator's context rather than
the completing thread's, which is what makes the pre-fix behaviour an
assertion instead of a wedged simulator. Compiled against the unfixed
sources the test fails 9 of the 24 expectations it reaches in the
uniprocessor tree and 10 of 24 in the SMP tree, and the failures are the
finding: the callback-side delete succeeds, the recreate succeeds, the
consistency snapshot disagrees, the target is neither terminal nor detached
when the service returns, and a peer has left the ready ring the recreated
block hijacked.

The SMP tree gets a second test for the case that needs concurrency. The
victim is excluded to core 1 and spins there without relinquishing while
the controller, excluded to core 0, terminates it, so the callback runs on
one core while the target executes on another. The callback-side reset and
delete must both be refused, and a sentinel written into the unused low end
of the victim's stack must survive -- a reset would have memset the whole
stack before rebuilding the frame. Every wait is bounded, and if the remote
precondition cannot be established the test says so and drops only the
assertions that depend on it rather than reporting a pass it did not earn;
measured over twenty consecutive runs it established the precondition every
time.

TX_NOT_INTERRUPTABLE and TX_DISABLE_ERROR_CHECKING are not among the five
build configurations either tree compiles, and each tree builds the whole
library once per configuration, so neither can be reached from inside the
suites. The lines this change adds under TX_NOT_INTERRUPTABLE are therefore
in no configuration the trees build, and they are where the permanent-
undeletability failure mode lives, so they get their own harness rather
than a compile check: the four sources plus the two error wrappers are
compiled directly into a test executable, once per combination, with
recorders standing behind the scheduler services they call. That is what
makes the marker's value at the moment of detachment directly observable.
It runs 66 expectations under TX_NOT_INTERRUPTABLE, 66 under that with
error checking disabled, 45 under that with notification disabled, and 63
under error checking disabled alone; against the unfixed sources those fail
25, 22, 6 and 20 respectively. The harness lives in the uniprocessor tree
only, because the four sources are identical between the kernels and the
shim replaces the very primitive the SMP port differs in, so a second copy
would compile the same text under the same macros. It is deliberately left
out of the coverage instrumentation, since the same source under different
feature macros has a different line set and merging those would confuse the
union rather than add to it.

Results. Both suites pass in all five configurations with GCC 14: 103 of
103 in the uniprocessor tree, up from 98, and 116 of 116 in the SMP tree,
up from 114. Merged line coverage is 100% in the uniprocessor tree and
5172 of 5183 in the SMP tree, whose eleven uncovered lines are the same
eleven that were uncovered before this change and are in tx_byte_pool_search
and tx_thread_smp_utilities; all four changed files are at 100% line
coverage in both trees, and SMP branch coverage rises from 2819 of 3548 to
2831 of 3556. Cross-compiled with arm-none-eabi-gcc at -Wall -Wextra for
Cortex-M4 against common and for Cortex-A7 SMP against common_smp, all four
files produce no diagnostics at all and an identical warning set to before
the change, under -std=gnu99 and -std=c99 alike -- unlike the module ports,
-std=c99 does not fail on these base ports, and even -Wconversion is clean.

No MISRA deviation is required: explicit comparisons to TX_TRUE, existing
ThreadX types, single-entry and single-exit control flow, no goto, and two
added constant-time tests that change no real-time complexity.

<title>Covered the SMP suspension teardown and the long byte pool search (#677)</title>

<id>urn:sha1:a2800fef16c5e229b71ce45050bf5fcf19d84bb2</id>
<content type='text'>
Against the merged SMP coverage report -- every build configuration instrumented
and unioned -- sixty-four lines of common_smp/src were uncovered, 5114 of 5178.
Fifty-three of them are closed here and the report reads 5167 of 5178. The SMP
coverage floor goes from 98 to 99 with it.

Thirty-six of the sixty-four were one loop repeated four times: the walk in
tx_block_pool_delete, tx_byte_pool_delete, tx_event_flags_delete and
tx_queue_delete that releases every thread suspended on the object with
TX_DELETED. The suite deletes all four object types after every single test, and
that is exactly why the loop never ran. test_control_cleanup in the ThreadX
suite deletes the application's objects first and its threads last, so a test
that ends with a thread parked on a queue has that thread walked out of it by
tx_queue_delete. The SMP suite's cleanup deletes the threads first, deliberately
-- it was changed so that no application-owned object is still referenced when
the object loops run, which is what stopped a class of teardown hang. The side
effect is that all four deletes now run against an empty suspension list.
tx_semaphore_delete is the one member of the family that was already covered,
because threadx_semaphore_delete_test deletes a busy semaphore on purpose.

threadx_object_delete_suspension_test is the same idea for the other four. Two
threads suspend on each of a block pool, a byte pool, an event flags group and a
queue; the control thread waits on the object's own suspended count through
tx_*_info_get rather than on an ordering it cannot guarantee across four cores,
deletes the object, and checks both waiters came out with TX_DELETED. Two
waiters rather than one so the loop takes its back edge as well as its body, and
every wait is bounded in ticks so a suspension that never arrives fails the test
instead of hanging it.

threadx_trace_entry_update_test and threadx_thread_misaligned_stack_test are
ports of the two tests that closed the equivalent gaps in common/src, and close
fourteen more lines here: tx_block_allocate 123, 175, 182, 319 and 326,
tx_byte_allocate 130, 210, 217, 359 and 366, tx_thread_system_suspend 504 and
560, tx_trace_object_register 221, and tx_thread_create 133. The one substantive
change is core confinement. The trace test needs thread 0 to suspend and thread
1 to then release what it waits for; on four cores thread 1 gives the block back
before thread 0 has suspended and the update block behind the suspension is
never reached, so both threads are excluded from cores 1 to 3. The misaligned
stack test needed no such change.

threadx_byte_memory_long_search_test closes three of the eleven in
tx_byte_pool_search. Lines 264, 267 and 270 are the
TX_BYTE_POOL_MULTIPLE_BLOCK_SEARCH limit -- twenty on this port -- where a long
search drops and retakes protection so that it cannot lock the other cores out
for the whole walk. No byte pool in the suite ever had twenty fragments. This
one is filled with small chunks until it refuses another and then has every
second chunk released, so the free fragments are never adjacent and cannot be
merged, and the request is larger than any of them but smaller than the pool's
theoretical total, which is what makes _tx_byte_pool_search walk rather than
refuse at the door. The layout is asserted rather than assumed: the test checks
the fragment count and checks the probe request really does fail before the
workers start, because either would otherwise turn it into a silent no-op.

Eleven lines remain and they are not a to-do list. Eight are the delay loop in
tx_byte_pool_search that fires when another thread claims the pool inside the
window the search opens. The Linux SMP port serialises all four cores on one
pthread mutex, so that window is an unlock immediately followed by a lock on
that mutex, and glibc hands an uncontended mutex straight back to the thread
that just released it: measured over 180,003 windows across three cores, with
zero handovers. The shipped test therefore does 250 searches per worker rather
than the sixty thousand that probe used, because the twenty-block threshold is
crossed by the first search. The other three are in tx_thread_smp_utilities.
Line 149 is a range guard placed after the shift it is meant to guard, so
reaching it needs a shift by the width of the type; the fix is to move the check
above the shift, matching the TX_MAX_PRIORITIES &gt; 32 variant of the same
function, and that belongs in its own change. Lines 1073 and 1074 need a mutex
owner that is genuinely executing on another core when a waiter suspends, and
three shapes were tried without producing one on this port.

Measured twice before and twice after, every gcda deleted between runs and
570 of 570 tests passing each time: 5114 of 5178 both times before, 5167 of 5178
both times after. Branch coverage goes from 2768 to 2821 and 2823 of 3548. A
floor of 99 needs 5127, so the ratchet lands with forty lines of headroom
against a numerator that has been seen moving by two between runs.

risc-v: refactor, consolidate, and fix RV32/RV64 ports

Consolidates the RISC-V 32-bit and 64-bit GNU/Clang port sources, fixes two
pre-existing assembly bugs discovered during testing, and hardens the build
infrastructure for both the regression suite and the CORE-V MCU example.

--- Port consolidation (RV32 GNU + Clang) ---

 - Delete ports/risc-v32/clang/src/ (8 .S files had no Clang-specific
 directives; diverged from GNU only due to missing bug fixes). The Clang
 port CMakeLists.txt now compiles from ../gnu/src/.
 - Change .global -&gt; .weak for _tx_initialize_low_level in gnu/src/ to allow
 BSP-level override without a linker conflict (adopted from Clang port).
 - Create ports/risc-v32/common/tx_port_riscv32_common.h with all definitions
 shared between GNU and Clang ports. Reduce both tx_port.h files to thin
 wrappers.
 - Add a prominent comment in risc-v64/gnu/inc/tx_port.h explaining why
 LONG/ULONG are intentionally 32-bit on RV64 (ThreadX ABI requirement,
 mirrors win64/MSVC LLP64).

--- Shared CMake helper ---

 - Add cmake/threadx_riscv_port.cmake with threadx_add_riscv_port(). All
 three port CMakeLists.txt files are reduced to ~8 lines each. Include path
 is relative to CMAKE_CURRENT_LIST_DIR so the helper works whether ports
 are built standalone or as a subdirectory of the test framework.

--- Shared example-build drivers ---

 - Create canonical driver files under ports/risc-v_common/:
  inc/csr.h                  (uintptr_t-based; portable RV32 + RV64)
  example_build/plic/        (plic.c, plic.h)
  example_build/uart/        (uart_qemu_ns16550.c/h; static inline putc_nolock)
  example_build/trap/        (trap_qemu.c; XLEN-portable mcause constants)
 - Replace per-example copies with symlinks in all qemu_virt and cva6_ariane
 example directories.
 - Fix OS_IS_INTERRUPT typo (was OS_IS_INTERUPT) in shared trap_qemu.c.
 - Gate print_hex() behind TX_RISCV_TRAP_DEBUG.

--- Bug fixes in RV32 assembly ---

tx_thread_schedule.S:

 - Solicited-return FP path: reload t0 from the mepc stack slot before
 csrw mepc, t0. After the FP restore block, t0 held the fcsr value (0 for
 new threads), which caused mepc = 0 and an immediate instruction-address
 fault on the first context switch.
 - Same path: reload t0 from the mstatus stack slot before csrw mstatus, t0
 to avoid writing the stale fcsr value into mstatus.

tx_thread_system_return.S:

 - FP callee-saved registers were saved unconditionally before the mstatus.FS
 check, causing an illegal instruction trap (mcause=0x2) when a thread with
 FS=Off (lazy FPU, thread has never used FP) voluntarily yielded.
 - Apply the same FS guard pattern used in tx_thread_context_save.S: read
 mstatus first, isolate FS[1:0], and skip fsw/fsd if FS == Off.

Both bugs were pre-existing on origin/dev and are unrelated to the
consolidation changes.

--- RV64 64-bit pointer compatibility ---

 - Add TX_TIMER_INTERNAL_EXTENSION, TX_THREAD_CREATE_TIMEOUT_SETUP, and
 TX_THREAD_TIMEOUT_POINTER_SETUP to risc-v64/gnu/inc/tx_port.h to store the
 thread timeout pointer in a VOID
  * extension field rather than truncating it
 into a 32-bit ULONG. Mirrors the win64 port pattern.
 - Define TX_TIMER_EXTENSION_PTR_DEFINED as a portable sentinel.
 - Update threadx_thread_basic_execution_test.c guard from #if defined(_WIN64)
 to #if defined(_WIN64) || defined(TX_TIMER_EXTENSION_PTR_DEFINED).
 - Disable -Wconversion for the RV64 test build: ULONG = unsigned int (32-bit)
 is intentional for ThreadX ABI but triggers spurious warnings when sizeof()
 (8 bytes on RV64) appears in arithmetic with ULONG in common/src/.

--- Regression suite cmake fixes ---

test/tx/cmake/riscv/regression/CMakeLists.txt:

 - Build testcontrol_weak_defaults.c as a separate OBJECT library and include
 it in every test executable via $&lt;TARGET_OBJECTS:&gt;. GNU ld does not extract
 objects from a static archive to satisfy weak symbols, so bundling it in
 test_utility was insufficient for the standalone
 threadx_initialize_kernel_setup_test.

test/tx/cmake/regression/CMakeLists.txt,
test/smp/cmake/regression/CMakeLists.txt:

 - Same fix applied to the Linux and SMP regression builds. The symbols
 abort_all_threads_suspended_on_mutex, suspend_lowest_priority, and
 abort_and_resume_byte_allocating_thread were introduced by the win64 merge
 and left the standalone test unlinkable.

--- CORE-V MCU toolchain and build fixes ---

cmake/riscv64-gcc-rv32imc.cmake:

 - Resolve riscv64-unknown-elf-gcc via PATH so the riscv-collab toolchain in
 /opt/riscv/bin is preferred when it appears first.

ports/risc-v32/gnu/example_build/core_v_mcu/bsp/clz.c (new):

 - The riscv-collab toolchain is built without rv32 multilib, so its libgcc
 does not define __clzsi2 (the helper emitted for __builtin_clz() in fll.c).
 Add a weak __clzsi2 fallback so the build is self-contained with any
 riscv64-unknown-elf toolchain. The weak attribute yields to a
 libgcc-provided strong symbol when the Ubuntu multilib package is used.

core_v_mcu/CMakeLists.txt:

 - Add bsp/clz.c to sources.
 - Reference CMAKE_TOOLCHAIN_FILE via message(STATUS) to suppress the false-
 positive "Manually-specified variables were not used by the project" CMake
 warning and to show the active toolchain at configure time.

--- Housekeeping ---

 - Rename azrtos_test_* -&gt; threadx_test_* (eliminate Azure RTOS branding).
 - Add RV64 QEMU CI test script:
  ports/risc-v64/gnu/example_build/qemu_virt/test/
  threadx_test_tx_gnu_riscv64_qemu.py
 - Normalize entry.s -&gt; entry.S in all 4 example directories.
 - .gitignore: exclude build_m7/ and .codex local artifacts.
 - CI: comment out the riscv regression workflow job and remove it from the
 deploy job's needs list (preserved in-place for easy re-enablement).

--- Verified ---

 - 95/95 RV32 regression tests pass (QEMU virt)
 - 95/95 RV64 regression tests pass (QEMU virt)
 - All 5 Linux build configurations build cleanly (default_build_coverage,
 disable_notify_callbacks_build, stack_checking_build,
 stack_checking_rand_fill_build, trace_build)
 - CORE-V MCU example_build links cleanly with /opt/riscv toolchain

 Windows x64 port and regression suite

 This PR adds the Windows x64 (Win64) simulation port for both the standalone
 and SMP variants of ThreadX, along with the full CMake build and test
 infrastructure needed to run the regression suite on Windows.


 New ports

 Win64 standalone (ports/win64/vs_2022): self-contained Windows simulation
 port using Win32 threading primitives as virtual cores. Includes CMake
 integration, build/test scripts, and MSVC project files.

 Win64 SMP (ports/win64_smp/vs_2022): multi-core Windows simulation port.
 Supports up to 4 virtual cores backed by Windows host threads.


 Scheduler and timer improvements

 The initial port used coarse polling and synchronous SuspendThread/ResumeThread
 pairs throughout the scheduler hot path. Several rounds of optimization reduced
 the SMP regression suite runtime from ~150 s to ~78 s (-48%), with no
 regressions:

 - Replaced scheduler polling with an event-driven wake path; switched the
   simulated timer to one-shot rearming to eliminate catch-up ticks.
 - Skip SuspendThread when _tx_thread_preempt_disable != 0 (new suspension
   type 3) -- the primary optimization, yielding up to 7.9x speedup on
   preemption-heavy tests.
 - Skip SuspendThread when a thread is spinning on the Win32 critical section
   (suspension type 4), and fix a stale-TLS bug in
   _tx_win32_critical_section_obtain that could stamp mutex_access on the
   wrong virtual core.
 - Added a 2 ms scheduler event timeout (matching the Linux SMP port) to
   prevent stalls on any missed SetEvent.
 - Enabled high-resolution waitable timers (SetWaitableTimerEx) for accurate
   100 Hz tick cadence.
 - Increased TX_WIN32_CONTENTION_PAUSE_COUNT from 64 to 256 to reduce
   SwitchToThread overhead under heavy CS contention.


 Build and test infrastructure

 - Hardened the Windows build wrapper (scripts/build_tx.ps1): invoke Ninja
   directly for Ninja build trees, fix timeout detection, add a default build
   timeout, and limit fallback replay to real timeout cases.
 - Added -Clean support to Windows test scripts to remove stale CTest state
   before each run.
 - Skip Visual Studio DevShell re-entry when the active MSVC environment
   already matches the requested architecture.
 - Fixed scripts/build_tx.sh (Linux) regression source generation: replaced
   brittle exact-string insertion with line-based matching so the interrupt
   dispatcher hook is inserted reliably for both simulator ports.


 Test suite updates

 - Introduced test/tx/regression/threadx_test_port.h with portable macros
   (TX_TEST_POINTER_WORD, TX_TEST_STORE_POINTER) for storing pointers in test
   arrays on 64-bit targets where ULONG remains 32-bit.
 - Adjusted pool-capacity and pointer-storage patterns in regression tests to
   use ALIGN_TYPE-sized slots, making the suite correct on 64-bit hosts.
 - Restored stricter event flag, sleep, and timer expectations now that
   port-level fixes make prior Windows accommodations unnecessary.
 - Tightened SMP watchdog and clean-build timeout defaults.


 Version metadata

 Updated Win32, Win64, and Win64 SMP port version strings to 6.5.1.202602.

Summary
-------
This commit fixes the issue #424

Details
--------
- Add a the configuration option TX_QUEUE_MESSAGE_MAX_SIZE in the tx_api.h with default value
  set to TX_ULONG_16 to keep backword compatibility.
- Update the txe_queue_create() to check on TX_QUEUE_MESSAGE_MAX_SIZE rather than TX_ULONG_16
  as max message size.
- Add a new unitary test to cover the new change.
