Stopped the remaining example scripts naming archives that were deleted (#620)
#618 fixed the arm9 and arm11 shell scripts, but not their .bat counterparts, and did not look at cortex_r4 and cortex_r5 at all. An audit of every build script against the files actually present in its directory found the rest. The .bat scripts for arm9, arm11, cortex_r4 and cortex_r5 still linked libc.a, libgcc.a and, for arm11, libnosys.a from their own example_build directories, and the cortex_r4 and cortex_r5 shell scripts did too. Those archives went in 6.1.10 under "Removal of unneeded files", so on Windows all four examples failed exactly as the shell versions did before #618, and on Linux the two R-profile ones still did. Link through the compiler driver, as the other examples have since #594. This does not make the examples link, and the change stops there deliberately. All four now fail the same way, undefined reference to `_fini' because their linker scripts define the .init and .fini sections but not the _init and _fini symbols, which live in crti.o and crtn.o and are omitted by -nostartfiles. Reviving four very old cores is separate work. Correct the comment on EXAMPLES_EXPECTED_TO_FAIL again. It had cortex_r4 and cortex_r5 failing for want of newlib multilib variants; they do not. All four share the single cause above, and the multilib explanation was wrong for the R-profile pair just as it was for arm9 and arm11. Verified by running each shell script: cortex_r4 and cortex_r5 fail on _fini rather than on missing files, matching arm9 and arm11. The .bat changes mirror link lines proven that way in the same directories; they cannot be run here. Three scripts are left alone and reported instead, because a blind edit could not be verified: ports_module/cortex_m3 and cortex_m4 have Windows-only .bat scripts that also name sources which are absent or differ in case, and ports_smp/mips32_interaptiv_smp needs a MIPS toolchain.

Removed generated build output and per-user IDE state, and fixed two stale link lines (#618)
* Removed generated build output and stopped two scripts naming deleted archives Three kinds of file in the tree are produced by a build rather than written by hand, and one pair of scripts still links archives that were deleted years ago. Keil writes ThreadX_Library.plg on every build; the two committed copies are HTML build logs from someone's machine. Code Composer generates the makefiles under ports/c667x/ccs/example_build/tx/Release from the project files beside them, so makefile, objects.mk, sources.mk, subdir_rules.mk, subdir_vars.mk and ccsObjs.opt are all regenerated output. The arm9 and arm11 sample builds link libc.a, libgcc.a and, for arm11, libnosys.a from their own example_build directories. Those archives were removed in 6.1.10 under "Removal of unneeded files", and libnosys.a in #594, but the link lines were never updated, so both examples fail immediately with arm-none-eabi-ld: cannot find libc.a: No such file or directory Link through the compiler driver instead, the shape every other example in the tree uses since #594: the driver supplies libc and libgcc, and SYSCALL_LIB is already defined in both scripts. That does not make either example link, and the fix stops short of that on purpose. With the archives no longer named, both now fail on undefined reference to `_fini' because their linker scripts define the .init and .fini sections but not the _init and _fini symbols, which live in crti.o and crtn.o and are omitted by -nostartfiles. Making those two old cores build is a separate question from removing a stale reference, so they stay in EXAMPLES_EXPECTED_TO_FAIL, with the comment there corrected: it blamed newlib multilib packaging, which is true of cortex_r4 and cortex_r5 but was never the reason for arm9 and arm11. Reproduced throughout with arm-none-eabi-gcc 13.2.1. Assisted-by: Claude Code (Opus 5) <noreply@anthropic.com> * Removed the Keil per-user state files and ignored them Every Keil project in the tree carried a second file holding per-user state: 25 .uvoptx beside the 25 .uvprojx, 9 .uvopt beside the 9 .uvproj, and 3 .uvgui multi-project workspace files. uVision rewrites all of them whenever a project is opened, so they record whoever last had it open rather than anything about the port: debugger selection, breakpoints, watch windows, window geometry. Nothing in the tree references them, and every affected directory keeps its .uvprojx or .uvproj, which is the file that actually describes the project. Add ignore rules so they do not come back the next time someone opens a project and commits. 1.4 MB across 37 files. Assisted-by: Claude Code (Opus 5) <noreply@anthropic.com> |

Added TX_ENABLE_FIQ_SUPPORT to the feature-macro assembly stage (#610)
#608 assembled the code behind TX_ENABLE_VFP_SUPPORT, TX_LOW_POWER and TX_ENABLE_EXECUTION_CHANGE_NOTIFY, and missed TX_ENABLE_FIQ_SUPPORT, which guards assembly in 145 files across the A and R profile ports. All 145 assemble today, so this adds no fix, only the regression protection the other three already have. Also recorded why TX_ENABLE_IRQ_NESTING and TX_ENABLE_FIQ_NESTING are not in the list, since their absence otherwise looks like the same oversight. They guard no assembly in the trees this script walks: the nesting start and end routines are separate files compiled unconditionally, and the macros only feed the TX_PORT_SPECIFIC_BUILD_OPTIONS bitfield in tx_port.h. Adding them would assemble nothing new while implying coverage that does not exist. Verified with Arm Toolchain for Embedded 22.1.0: 711 of 711 assembly sources, then 37 of 37 VFP, 145 of 145 FIQ, 8 of 8 TX_LOW_POWER and 218 of 218 TX_ENABLE_EXECUTION_CHANGE_NOTIFY.

Assembled the code behind feature macros, and fixed the POP it found (#608)
scripts/check_clang.sh assembled every source with default flags, so the
preprocessor discarded each #ifdef block before the assembler saw it. Nothing in
the tree had ever assembled a guarded path. That covers the VFP context save and
restore in ten ports, and 218 files carrying TX_LOW_POWER or
TX_ENABLE_EXECUTION_CHANGE_NOTIFY.
Turning those on found a defect. The Cortex-M0 and Cortex-M23 execution-profile
paths bracket their call with
PUSH {r0, lr}
BL _tx_execution_isr_enter
POP {r0, lr}
and the last of those is invalid on Armv6-M and Armv8-M Baseline, where the
16-bit Thumb POP takes r0-r7 and pc and nothing else. GNU rejects it as well --
"cannot honor width suffix" -- so TX_ENABLE_EXECUTION_CHANGE_NOTIFY and
TX_EXECUTION_PROFILE_ENABLE have never been buildable on either port with either
toolchain. Four files, all the same shape.
The fix pops into a scratch register and moves it, MOV to a high register being
permitted where POP is not. r1 is free: the BL may clobber r0-r3, which is the
reason r0 is saved in the first place. Disassembling the result gives
push {r0, lr} / bl / pop {r0, r1} / mov lr, r1 / bx lr, one 16-bit instruction
more than before and otherwise the same.
Two findings that were not defects, recorded in the script so they are not
rediscovered:
Cortex-R4 needs an -mfpu to assemble its VFP path, because its FPU is an option
rather than part of the core. GNU fails identically without one, so this is a
flags requirement and not a toolchain divergence.
The A profile ports must not be given one. Adding -mfpu=vfpv3-d16 uniformly broke
28 files with "register expected", because those ports save D16-D31 and a -d16
FPU does not have those registers. Their defaults were already right.
The new stage runs under --asm-only as well, needing no target C library, and
reports 37 of 37 VFP files, 8 of 8 TX_LOW_POWER and 218 of 218
TX_ENABLE_EXECUTION_CHANGE_NOTIFY. Restoring the POP for one run makes it fail
with 217 of 218 and name the file and the error, so the stage is not vacuous.
The other four stages are unchanged: 711 of 711 assembled, 185 of 185 common C
sources for each of nine cores, 42 of 42 script-driven examples and 5 of 5 CMake
images.
The fixed code is verified to assemble with both toolchains and to encode as
intended. It is not verified running: there is no Cortex-M0 or Cortex-M23 model
here, and these are context save and restore paths, so that gap is worth stating.

Brought the Cortex-R52 examples under the LLVM check, and fixed two blockers (#604)
#600 added a line reporting which example builds the LLVM check passes over, and cortex_r52 was on it: its examples are driven by CMake rather than by a build_threadx.sh pair, so the linking stage never touched them. Covering them turned up two reasons they could not have been built with anything but GNU. .arch armv8-r has no portable spelling. GNU as accepts it, and LLVM's integrated assembler rejects every variant -- armv8-r, armv8r, armv8-r+crc -- with "Unknown Arch: armv8-r". There is nothing to substitute, so the directive is gone from entry.S and tx_initialize_low_level.S; -mcpu=cortex-r52 already selects the architecture, both toolchain files pass it, and the directive only restated it. Worth noting where this hid: the assembly stage walks ports/*/gnu/src, so example assembly had never been assembled by LLVM at all. -Wl,--no-warn-rwx-segments is GNU ld only, added in binutils 2.39. ld.lld does not warn about RWX segments and rejects the flag outright, failing the link with "unknown argument". It is now selected on CMAKE_C_COMPILER_ID rather than spelled into all six targets, and the reason it exists at all -- a bare-metal image has one flat DRAM region and leaves access control to the MPU -- moves to the one place that sets it. cmake/cortex_r52_clang.cmake is the toolchain file. It names the tools as found on PATH, which is what CI uses, then pins $HOME/toolchains if that directory exists, mirroring how cortex_r52.cmake pins the GNU toolchain and for the same reason. Falling back rather than requiring the pinned path keeps the file usable on a machine that keeps clang elsewhere. THREADX_TOOLCHAIN stays "gnu": there is no clang port directory, this builds the gnu sources with a different compiler, which is what the whole check does for every other Arm port. check_clang.sh gains a fourth stage for CMake-driven examples, and no longer reports cortex_r52 as a gap. It reads the image list out of the generated ninja graph rather than repeating it, so adding a target cannot escape the check, and filters out the cmake_object_order_depends_target_* phonies -- counting those reported ten images where there are five. Verified with Arm Toolchain for Embedded 22.1.0, the version the workflow pins. All five images link, and all five then run and pass on FVP_BaseR_AEMv8R: boot_check, demo_m2, demo_m3, demo_threadx and demo_mpu. That is a step beyond the AArch64 examples, which are link-verified only. The full check reports 711 of 711 assembly sources, 185 of 185 common C sources for each of nine cores, 42 of 42 script-driven examples and 5 of 5 CMake images, leaving only cortex_a5_smp, cortex_a7_smp and cortex_a9_smp listed as having no driver. GNU is unaffected: the same five images build with no warnings and the FVP test suite passes 5 of 5. Assisted-by: Claude Code (Opus 5) <noreply@anthropic.com> |

Enrolled the Cortex-R52 port in the LLVM C check and exposed the skipped examples (#600)
Two gaps in check_clang.sh, both of which made the Cortex-R52 port look better covered than it was. C_CORES gains cortex_r52. That list is described as one core per architecture profile, and Armv8-R AArch32 is a profile rather than a variant of Armv7-R: the port is written by hand instead of generated from ports_arch, so cortex_r5 does not stand in for its tx_port.h. The assembly was already covered, since #593 added the PORT_TARGET entry, but the common C sources had never been compiled against that header. The example stage skipped any directory lacking both driver scripts, and did so in silence. A port absent from the count reads as covered, which is how the two CMake based example builds under ports/cortex_r52 looked like part of the total while never being built. The stage now reports what it passed over, in the two distinct cases that exist. The comment above EXAMPLES_EXPECTED_TO_FAIL already asks for gaps to stay visible; this makes the code agree with it. Four Cortex-M ports turn out to carry build_threadx.sh with no build_threadx_sample.sh, so they were skipped despite having a driver: cortex_m23, cortex_m33, cortex_m55 and cortex_m85. Reported, not fixed. Whether those want a sample script is a separate question. The expected-to-fail test now runs before the Arm test rather than after. arm9 and arm11 are on that list but carry no PORT_TARGET entry, so testing for Arm first dropped them from the report entirely, reintroducing the same silence for two ports that were already being named. Verified with Arm Toolchain for Embedded 22.1.0, the version CI pins: 711 of 711 assembly sources, 185 of 185 common C sources for each of the nine cores including cortex_r52, and 38 of 38 example builds linking, so the built set is unchanged by this commit. The remaining driverless ports report as cortex_r52, cortex_a5_smp, cortex_a7_smp and cortex_a9_smp, the three A profile SMP ports having no example scripts and the R52 examples being driven by CMake. --help still frames the intended lines, since the additions sit below the range it selects by number.

Repaired the garbled description at the top of check_clang.sh (#598)
The comment block describing what the script does was left half-rewritten when the example link stage was added to it: one sentence ends mid-clause and the word "profile" appears twice, once as the tail of a sentence that was meant to be replaced. Say the three stages plainly instead, and keep the point the truncated sentence was making, that only the linking stage needs a target C library. This block is what --help prints, so the damage was user visible. Comment only; no behaviour change. Verified that --help still frames the intended lines, since it selects them by number.

Added build scripts for the AArch64 examples, which had none (#597)
The AArch64 examples could only be built through the Arm Development Studio project files beside them. There was no script, so nothing in CI or on a developer's machine could build them, and the sources they need were never named anywhere: vectors.S, v8_aarch64.S and v8_utils.S were present but unreferenced, which is why a hand written link failed on GetCPUID, GetAffinity, InvalidateUDCaches and ZeroBlock. Those four are defined in v8_aarch64.S and v8_utils.S, in the tree all along. Add one pair of scripts, in ports_arch so every AArch64 port receives them. Both derive the -mcpu value and the kernel source directory from the port directory they sit in, so a single pair serves the twelve ThreadX ports and the twelve SMP ports, the latter building against common_smp and picking up the C sources those ports carry alongside the assembly. TOOLCHAIN=atfe selects Arm Toolchain for Embedded in place of the GNU toolchain, as it does for the ARMv7 example scripts. One symbol genuinely had no definition. startup.S calls initialise_monitor_handles to open the standard file handles over a debugger connection; the GNU toolchain provides it in libgloss through --specs=rdimon.specs, while picolibc has no equivalent and neither does the LLVM toolchain's semihosting library. semihost_stub.S supplies a weak no-op, linked for that toolchain only, so a real definition always wins. Extend scripts/check_clang.sh to cover ports_smp as well as ports, since the example builds now exist there too. Verified by building every AArch64 example with Arm Toolchain for Embedded: twelve ThreadX ports at 314,744 to 315,256 bytes of text and twelve SMP ports at 325,304 to 325,880. scripts/check_clang.sh now reports 35 of 35 example builds linking with none failing, the twenty-four new ones plus the eleven that already built. The images have not been executed: the sample targets the Base platform peripheral addresses, which the available emulator does not provide. Cortex-A34, and the Cortex-A34 and A78 SMP ports, are left out. They are not in the generator's core list, so they receive nothing from ports_arch and cannot be checked for reproducibility either. Bringing them in rewrites 114 files in those three directories, which deserves its own change. Assisted-by: Claude Code (Opus 5) <noreply@anthropic.com> |

Made the Cortex-A12, A15 and A17 examples link with an LLVM toolchain (#596)
Those three sample scripts compiled crt0.S and reset.S but named neither on the link line, and omitted -nostartfiles, so the toolchain was also free to link its own startup. Under GNU that produced a working image; under an LLVM toolchain picolibc's crt0 was pulled in and wanted __data_start, __data_source, __data_size, __bss_size, __stack, __tls_base and __arm32_tls_tcb_offset, none of which the linker script defines. Defining picolibc's contract in the shared linker script was tried first and abandoned: it reaches into ABI constants that cannot be verified here, and it is unnecessary, because the in-tree crt0.S is already a complete startup for this script. It sets up the stack and zeroes BSS between __bss_start__ and __bss_end__, and .data carries no AT() so there is nothing to copy. So the three scripts now pass -nostartfiles and name crt0.o and reset.o, which is what the four sibling A profile cores already do and what these scripts were evidently compiling those files for. Both the old and the new GNU images contain the in-tree startup, __vectors from reset.S and _mainCRTStartup from crt0.S, so the startup was already being used through implicit startup file resolution rather than an explicit operand. How that resolution happened without the objects being named is not accounted for here, which is itself the argument for naming them: the same implicit behaviour does not hold across toolchains, and that is why the LLVM link failed. Add a readme to each of the three example directories. Their tx_initialize_low_level.S is the generic ARMv7-A skeleton, 300 lines and identical across all three, with no interrupt controller programming, no timer and no vector table installation, where the A5, A7, A8 and A9 examples have all three and ship the matching Versatile Express support files. These three therefore demonstrate that the port builds; they will not receive a timer tick. Nothing in the tree said so, which invites the assumption that they are equivalent. Verified with both toolchains for all three cores. GNU links at 41,276 bytes of text, down from 41,768 because the unused toolchain startup is no longer included, and Arm Toolchain for Embedded links at 37,982 where it previously could not link at all. The resulting image is structurally sound: entry at _start, __vectors at address zero, and a BSS range in RAM. It has not been executed. scripts/check_clang.sh now links eleven of eleven example builds. Assisted-by: Claude Code (Opus 5) <noreply@anthropic.com> |

Completed the Cortex-M0 barriers and made its example build with both toolchains (#595)
Two unrelated Cortex-M0 gaps, both left over from earlier work. The memory barriers from #523 reached the Cortex-M0 gnu port but not its ac6 or iar siblings, in either the inline system return in tx_port.h or the assembly routine. Both take the same GNU or IAR code path, and iar already carried the entry barrier, so the missing pieces were the entry pair for ac6 and the barrier after restoring the interrupt posture for both. All three tools now match. The Cortex-M0 example could not link with any toolchain. cortexm0_crt0.S references 23 linker script symbols and the script defined only 12 of them, so __text_start__, __text_end__, __text_load_start__, the rodata and fast section symbols, and the ctors and dtors load addresses were all unresolved. The Cortex-M4 script defines all 23, including a .fast section with no content whose symbols exist so that the startup copy is a no-op, and its comment says as much. The Cortex-M0 script is brought to that same shape. That left the example failing under LLVM only, on instructions that ARMv6-M can encode just one way. The file declared .code 16 but no syntax mode, so GNU as used the legacy divided syntax in which a plain add or sub sets the flags implicitly, while LLVM implements unified syntax only and rejected the non-flag-setting spelling. Declaring .syntax unified and writing movs, adds and subs makes both assemblers agree, and the encodings GNU produces are byte identical before and after, verified by disassembling both objects. The Cortex-M0 example now links with GNU at 22,520 bytes of text and with Arm Toolchain for Embedded at 22,866, so it comes off the list of examples not expected to link and scripts/check_clang.sh now links eight of eight.

Made the example builds work with LLVM, and fixed four that were broken on Linux (#594)
* Made the example builds work with LLVM, and fixed four that were broken on Linux The gnu example builds are the natural LLVM path: Arm Toolchain for Embedded is LLVM based, consumes GNU ld linker scripts, and needs none of the scatter files or Arm DS projects the ac6 examples carry. So rather than port the ac6 examples, teach the gnu scripts to drive either toolchain. Each script now selects the toolchain from a TOOLCHAIN variable that defaults to gnu, so every existing invocation behaves exactly as before. TOOLCHAIN=atfe switches the compiler, adds the target triple, passes the entry symbol through to the linker rather than to the driver, and links the toolchain's own semihosting library in place of --specs=nosys.specs, which is a GCC spec file mechanism with no LLVM equivalent. That last choice avoids adding a syscall stub source to every example. The scripts are parameterised rather than duplicated. Copies of build scripts would drift the first time one side was edited, which is the failure this repository has just spent several changes recovering from. Four sample scripts could not run on a case-sensitive filesystem at all. They compiled MP_PrivateTimer.s and V7.s while the files on disk are MP_PrivateTimer.S and v7.s, and the Cortex-A5 and A9 scripts named MP_GIC.s where the file is MP_GIC.S. The link lines named V7.o accordingly. Corrected to match the files, which is why the Cortex-A5, A7, A8 and A9 examples now build on Linux where before they could not. Extend scripts/check_clang.sh to link the example builds as well as compile the sources, since compiling proves the sources parse while only linking exercises entry symbols, linker scripts and the C library together. Eight examples are listed as not expected to link, each with its reason, so the gaps stay visible rather than being silently skipped. Five of them fail with the GNU toolchain too and are therefore not LLVM problems: the Cortex-M0 example's crt0 references __text_load_start__, __text_start__ and __text_end__, which its linker script never defines, while the Cortex-M4 script defines the equivalents; the arm9, arm11, Cortex-R4 and Cortex-R5 examples need newlib multilib variants that are not present in every GNU toolchain packaging. The Cortex-A12, A15 and A17 examples fail only with LLVM, because their link line omits -nostartfiles so the toolchain's own crt0 is linked and wants picolibc's __data_start, __data_source, __data_size and __bss_size, which their linker script does not define. Verified by building every example with both toolchains. Seven link with both: Cortex-A5, A7, A8, A9, M3, M4 and M7. The GNU results are unchanged where they worked before, and now also succeed for the four scripts with the case bug. Assisted-by: Claude Code (Opus 5) <noreply@anthropic.com> * Resolved the compiler path before running the example builds The example stage runs each build script from inside its own directory, so a relative path passed with --clang stopped resolving there and every example build failed instantly. Local runs passed an absolute path and did not show it; the CI job passes a path relative to the workspace root, which did. Resolve the compiler to an absolute path once, before any directory change, and print it so the toolchain in use is visible in the log. Assisted-by: Claude Code (Opus 5) <noreply@anthropic.com> * Parameterised the archiver as well, and stopped the check hiding failures The toolchain selection covered the compiler but not arm-none-eabi-ar, which the scripts invoke 628 times to assemble the library archive. A machine with an LLVM toolchain and no GNU one therefore could not build any example, which is exactly the situation in CI: the runner has no Arm GNU toolchain installed. Local runs had one, so this only appeared once the job ran. Select the archiver alongside the compiler, taking llvm-ar from beside clang in the toolchain. The four scripts that call arm-none-eabi-ld directly are left alone: they are arm9, arm11, Cortex-R4 and Cortex-R5, all already listed as not expected to link, and their invocations are specific to GNU ld in ways that parameterising would not resolve. The check reported "example build produced no image" and then filtered the log for lines containing "error", which hid the actual cause, since a missing tool reports "command not found" or "No such file or directory". It now prints the tail of the log. That filtering cost two CI round trips to diagnose something the first run already knew. Verified by shadowing arm-none-eabi-gcc, arm-none-eabi-ar, arm-none-eabi-ld and the aarch64 equivalents with stubs that fail loudly, then running the whole check: all 711 sources assemble, all eight profiles compile and all seven example builds link without any GNU tool being invoked. The GNU default path still produces an identical image. The diagnostics were confirmed by pointing the archiver at a name that does not exist and checking that the reason appears.

Made the Arm ports build with LLVM, and added a check that keeps them that way (#593)
The gnu ports are only ever built with GNU tooling, and GNU as accepts several non-canonical forms that LLVM's assembler rejects. Nothing noticed, because nothing built them with anything else. This matters beyond clang itself: Arm Toolchain for Embedded is LLVM based and is the successor to Arm Compiler 6, so these are the code paths ac6 users move onto. Seven files needed changing, none of which alters the emitted code: LDREX and STREX take no offset in A32 state; the #imm form is Thumb-2 only. GNU as drops the redundant zero, LLVM rejects it. Removed from the Cortex-A5, A7 and A9 SMP protect routines. ARMv8-M Baseline has no flag-preserving MOV immediate, so GNU as already emits MOVS. Writing MOVS in the two Cortex-M23 sources says what the assembler was doing anyway. One of them sits in a branch only compiled for the single mode secure configurations, which is why it had never surfaced. The Cortex-M0 schedule routine wrote LDR r0, =#0x10000000 with a stray hash, which its own sibling file already wrote correctly. The Cortex-M0 system return routine selected the numbered subsection .text 32, which makes LLVM place the constant pool beyond the range a Thumb-1 PC relative load can reach. Plain .text fixes it and GNU accepts either form. The reason is recorded in the file, since 32 files pair a numbered subsection with a literal pool load and the rest only escape because Thumb-2 and A32 have far more range. Add scripts/check_clang.sh, which assembles every Arm gnu port source and compiles the common C sources for one core per architecture profile, and a clang_check workflow that installs Arm Toolchain for Embedded and runs it. The toolchain version is pinned and checksum verified, for the same reason the runner image is pinned. The port directory to target mapping in that script is explicit rather than prefix matched. Prefix matching is what makes cortex_a5 also match cortex_a53 and cortex_a55, which are AArch64, and assembling those as ARM32 produces hundreds of misleading errors; that mistake cost real time while measuring this, so the reason is recorded next to the table. Verified with Arm Toolchain for Embedded 22.1.0: 711 of 711 assembly sources assemble and 185 of 185 C sources compile for all eight profiles, against 6 assembly failures before the change. arm-none-eabi-gcc still assembles all 315 ARM32 sources, so nothing regressed for GNU. The check was confirmed to fail when any one of the fixes is reverted. Assisted-by: Claude Code (Opus 5) <noreply@anthropic.com> |

Added bash A profile update scripts and restored ports_arch as their source (#592)
The ARMv7-A and ARMv8-A ports are generated by update.ps1, which needs PowerShell, so the cortex-a job in ports_arch_check ran on a Windows image and nobody could reproduce it locally on Linux. Add update.sh beside each update.ps1, with the same cores, compilers, copy sets and patches, and move the job to the same Linux image as everything else. The bash scripts were checked against the PowerShell ones by comparing what each reports as drifted. They agree exactly on the 63 files the Windows job last reported, and differ on 12 more, which turn out to be a defect in update.ps1 rather than in the port. Its two .cproject patterns are written as 'value=`"cortex-a7`"' with backticks that survive into the pattern, so that replacement has never matched, while the neighbouring Cortex-A7.NoFPU pattern has no backticks and always worked. The result is that the AC6 example builds for the A5, A8, A9, A12, A15 and A17 cores name cortex-a7 as their CPU while their FPU string is correct. The bash scripts do what the PowerShell ones intended, so regenerating corrects those twelve files. Restore ports_arch as the source for the rest. The implementation of _tx_thread_smp_time_get from #555 was applied to the twenty four generated SMP ports and never to ports_arch, which still held MOV x0, #0 with a FIXME comment, so regenerating would have replaced a working generic timer read with a stub. That implementation now lives in the source. The remaining differences are cosmetic and resolve in favour of the source: a trailing blank line in 38 copies of tx_thread_schedule.S and comment spacing in one tx_port.h. Note that the Cortex-A VFP fix is already present in ports_arch and was never at risk, contrary to what the description of the port consistency checks change said before this was measured. Extend scripts/check_ports.sh to run the A profile generators too, and make it fail when a generator fails or is missing rather than reporting a clean tree, which would have been a false pass. Pin every workflow to ubuntu-24.04. ubuntu-latest already resolves to that image, so nothing changes today, but a future migration becomes a deliberate commit rather than something that happens underneath the -m32 builds.

Added port consistency checks and wired them into CI and release preparation (#591)
Three defects reached the repository through the port trees recently, and each of them is mechanically detectable without a cross compiler. Add scripts/check_ports.sh, which looks for exactly those three, and give CI and the release process the same command a contributor can run locally. The generated Cortex-M ports must be reproducible from ports_arch. Fixes were applied to the generated copies instead of the source for eight months, and the next run of the copy scripts would have reverted them. Preprocessor directives must balance. A fix left the Cortex-M85 IAR tx_port.h with one more #endif than #if, so that header could not compile. No port header may carry a statement outside a function body. A fix left a second, headerless copy of a function body in the Cortex-M4 AC6 tx_port.h, which is issue 569. The check tracks brace depth while skipping preprocessor lines, multi-line macro bodies and comments, and reports assignments, dereferences and control statements that land at file scope. Headers under example_build are excluded, since those trees vendor third party SDK code. A fourth section reports, without failing the run, on port families that have no copy script and so cannot be checked for reproducibility. It currently observes that the Cortex-M0 ac5, ac6 and keil ports lack the barriers their gnu and iar siblings have. ports_arch_check now calls the script rather than inlining a copy and diff, so CI and the command line check the same things by the same definition, and the workflow now triggers on pull requests to dev as well as master. Triggering on master alone is why the drift went unseen. prepare_release.sh runs the checks before it branches or rewrites anything, and stops if they fail, with SKIP_PORT_CHECKS=1 as the escape hatch. Each check was verified by reintroducing the defect it exists to catch and confirming that the script fails, then confirming it passes on a clean tree.

Added a regression suite for the FreeRTOS compatibility layer (#583)
* Fixed the resource leaks on the xQueueCreate error paths xQueueCreate() allocated the queue descriptor and its backing memory, then created two ThreadX semaphores, and returned NULL on either semaphore failure without releasing anything. Since no handle reached the caller, vQueueDelete() could not be used to recover, so both allocations were lost. A failure on the second semaphore additionally abandoned the read semaphore it had already created, leaving a live ThreadX control block inside freed memory. Release the backing memory and the descriptor on both paths, and delete the read semaphore before returning when the write semaphore cannot be created. This is the teardown order vQueueDelete() already uses, and it matches the cleanup xTaskCreate() performs on its own error paths. Verified with a fault injection harness that intercepts the ThreadX byte pool and semaphore entry points to force tx_semaphore_create() to fail on a chosen call. On a read semaphore failure the layer previously performed 2 allocations and 0 releases, and on a write semaphore failure 2 allocations, 0 releases and 0 semaphore deletions. It now performs 2 releases in both cases and deletes the read semaphore in the second, with the byte pool restored to its prior state. Fixes https://github.com/eclipse-threadx/threadx/issues/570 Assisted-by: Claude Code (Opus 5) <noreply@anthropic.com> * Added a regression suite for the FreeRTOS compatibility layer The compatibility layer had no tests in this repository, which is awkward for its creation functions in particular. Each of them takes one or two byte pool allocations for its bookkeeping and then creates ThreadX kernel objects, and each returns NULL when a kernel object cannot be created. The caller is left without a handle, so it cannot call the matching delete function, and anything the layer failed to release is gone until the system restarts. A leaking version and a correct version are indistinguishable from the outside, which is how the leak in issue 570 went unnoticed. Add a suite that counts what the layer takes and gives back. A test asks the harness to fail a chosen kernel creation call, then checks the number of byte pool allocations, releases, object creations and object deletions performed. The ThreadX entry points are intercepted with the linker's --wrap so that tx_freertos.c is compiled exactly as it ships, with no test hooks in it. Note that tx_api.h maps the public API onto the error checking entry points, so the _txe_ symbols are the ones wrapped. Coverage is the creation and teardown paths of queues, tasks, semaphores, mutexes, event groups and timers, including a regression test for the two paths fixed for issue 570. The suite follows the layout of the existing ThreadX and SMP suites, is registered with ctest, and runs in CI through the shared regression template. It is built 32 bit because the Linux port defines ULONG as unsigned int on x86_64 while the layer passes pointers through ULONG arguments, so a 64 bit build truncates them. It is Linux only because --wrap has no MSVC equivalent, and the CMake configuration says so rather than failing at link time. Validated by building the suite against the layer as it stands before the issue 570 fix, where the two expected checks fail with the leaked counts, and against the fixed layer, where all three tests pass.

Added win64 ports of ThreadX and ThreadX SMP (#529)
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.

Add QEMU based CI regression test infra for RV32 and RV64 (#526)
Added a QEMU virt-machine BSP and CTest infrastructure to run the ThreadX regression suite on both RISC-V 32-bit and 64-bit targets in CI. New components: - BSP (entry, trap, PLIC, CLINT timer, UART, linker script) targeting QEMU virt machine for RV32 and RV64 - CMake build system with Ninja, supporting multiple build configs - CI scripts: install_riscv.sh (toolchain + QEMU), build_tx_riscv.sh, test_tx_riscv.sh - GitHub Actions workflow job for RISC-V regression gating Port fixes: - RV32 tx_thread_context_restore.S: set MPIE alongside MPP (0x1800 → 0x1880) so mret re-enables interrupts - RV32/RV64 tx_port.h: add TX_REGRESSION_TEST extension macros needed by the test harness - RV32/RV64 example_build scripts: add compile and QEMU launch steps Regression test portability fixes: - Block memory tests: increase pool sizes (320 → 340) to accommodate larger RISC-V block-header alignment - Byte memory test: replace hardcoded offsets with BYTE_POOL_OVERHEAD macro for portable pool-size computation - Event flag timeout test: make counter tolerance unconditional, removing linux-only guard Signed-off-by: Akif Ejaz <akif.ejaz@10xengineers.ai> |
