Updated ThreadX version constants and port strings to 6.5.2.202603 (#781)

2026-09-28T18:36:10Z

ThreadX still declares 6.5.1.202602 with hotfix 'a', which is the previous release rather than the one being cut. prepare_release.sh updated the five version constants in tx_api.h and the version string in 211 port headers across ports, ports_smp, ports_arch and ports_module. The hotfix letter is cleared, since the target has none. Nothing else changed: every line in the port commit carries a version, and no file outside an inc/tx_port.h was touched. The port consistency checks passed before the branch was cut, which is what the script gates on. Host regression 113/113 with zero warnings, and the AI disclosure check passes.

Normalized the AI disclosure comment to one fixed line per file (#740)

2026-09-15T21:17:26Z

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. Assisted-by: Claude Code (Opus 5)

Replaced the GNU-only dsb/isb 0xF operands with the UAL sy form (#729)

2026-09-15T20:24:45Z

Fixes #551 `_tx_thread_system_return_inline()` in the Cortex-M `tx_port.h` headers spells its barriers `dsb 0xF` and `isb 0xF`. A bare hexadecimal operand is a GNU assembler extension, and IAR rejects it with `operand syntax error`, so the header cannot be included at all. The block is guarded for GCC, armclang and IAR together, so every IAR user of an affected port hits it -- four independent reports on Cortex-M33 and M7 with EWARM 9.50 and 9.70. Both operands become `sy`, the Arm UAL name for exactly what `0xF` encodes. The generated instruction is unchanged. Applied to the two `ports_arch` masters and all 32 copies under `ports`, covering M0, M23, M3, M33, M4, M52, M55, M7 and M85 across ac5, ac6, gnu, iar and keil, plus the `scripts/check_ports.sh` probes that matched the old spelling. `check_ports.sh` passes, the copy scripts still reproduce every generated port byte for byte, and `arm-none-eabi-gcc -O2` compiles a caller for every patched header, emitting `dsb sy` and `isb sy`. Three headers that need toolchain intrinsics GCC does not ship fail identically on `dev`. Assisted-by: Copilot (Opus 5)

Restored ports_arch as the source of truth for the Cortex-M ports (#590)

2026-08-09T14:42:54Z

The Cortex-M ports under ports/ are generated. scripts/copy_armv7_m.sh copies one tx_port.h and the per tool sources to fifteen M3, M4 and M7 targets, and scripts/copy_armv8_m.sh does the same for nine M33, M55 and M85 targets. The ports_arch_check workflow runs both scripts and fails if the tree is not reproducible, so those copies are meant never to be edited directly. They were. Every Cortex-M fix since #523 was applied to the generated copies and not to the source, so the source fell behind and the check went red: running the three scripts on dev changes 35 files. The check triggers only on pull requests targeting master, which is why nothing caught it while the fixes were merged into dev. Left alone, the next run of these scripts would have reverted three separate pieces of work: the memory barriers and clobbers from #523, the correction of the IAR assembly header to use the assembler's own comment syntax, and the move of tx_initialize_low_level.S into example_build for the M33, M55 and M85 GNU ports from #514. Bring the sources up to what the ports carry today, and regenerate. Two behavioural changes come with that, both deliberate. The barriers from #523 reach the ac5 and keil variants of M3, M4 and M7, which were outside the scope of that fix and never received it. The barrier that follows restoring the interrupt posture, which #523 gave only to the GNU ports because GNU was the only toolchain that could be tested, now applies to every tool; the identical asm statement already shipped in the AC6 and IAR ports, so this adds a pipeline flush rather than any new compiler exposure. Regenerating also drops a stray #endif at the end of the Cortex-M85 IAR tx_port.h, added by #523, which left that header with one more #endif than #if and unable to compile. Every other ARMv8-M port was balanced. Verified that the scripts are idempotent afterwards, that ports_arch_check would pass, that no port loses a barrier or a clobber, that every regenerated header is preprocessor balanced, and that every Cortex-M port covered by the two scripts now carries the entry barrier.
