2025-07-13selftests/nolibc: add x32 test configurationThomas Weißschuh
Nolibc supports the x32 ABI on x86. Add a testcase to make sure the support stays functional. QEMU user does not have support for x32, so skip the test there. Signed-off-by: Thomas Weißschuh <linux@weissschuh.net> Acked-by: Willy Tarreau <w@1wt.eu> Link: https://lore.kernel.org/r/20250712-nolibc-x32-v1-2-6d81cb798710@weissschuh.net
2025-07-04tools/nolibc: add support for SuperHThomas Weißschuh
Add support for SuperH/"sh" to nolibc. Only sh4 is tested for now. The startup code is special: __nolibc_entrypoint_epilogue() calls __builtin_unreachable() which emits a call to abort(). To make this work a function prologue is generated to set up a GOT pointer which corrupts "sp". __builtin_unreachable() is necessary for __attribute__((noreturn)). Also depending on compiler flags (for example -fPIC) even more prologue is generated. Work around this by defining a nested function in asm.

2025-06-28tools/nolibc: MIPS: add support for N64 and N32 ABIsThomas Weißschuh
Add support for the MIPS 64bit N64 and ILP32 N32 ABIs. In addition to different byte orders and ABIs there are also different releases of the MIPS architecture. To avoid blowing up the test matrix, only add a subset of all possible test combinations.

2025-06-23selftests/nolibc: rename MakefileThomas Weißschuh
The nolibc tests are not real kselftests, they work differently and provide a different interface. Users trying to use them like real selftests may be confused and the tests are not executed by CI systems. To make space for an integration with the kselftest framework, move the custom tests out of the way. The custom tests are still useful to keep as they provide functionality not provided by kselftests.

2025-05-21tools/nolibc: Add m68k supportDaniel Palmer
Add nolibc support for m68k. Should be helpful for nommu where linking libc can bloat even hello world to the point where you get an OOM just trying to load it.

2025-03-02selftests/nolibc: add armthumb configurationThomas Weißschuh
While nolibc does support ARM Thumb instructions, that support was not tested specifically. Add a new test configuration for it.

2025-02-20tools/nolibc: add support for 32-bit s390Thomas Weißschuh
32-bit s390 is very close to the existing 64-bit implementation. Some special handling is necessary as there is neither LLVM nor QEMU support. Also the kernel itself can not build natively for 32-bit s390, so instead the test program is executed with a 64-bit kernel. Acked-by: Willy Tarreau <w@1wt.eu> Link: https://lore.kernel.org/r/20250206-nolibc-s390-v2-2-991ad97e3d58@weissschuh.net Signed-off-by: Thomas Weißschuh <linux@weissschuh.net>
2025-02-20selftests/nolibc: rename s390 to s390xThomas Weißschuh
Support for 32-bit s390 is about to be added. As "s39032" would look horrible, use the another naming scheme. 32-bit s390 is "s390" and 64-bit s390 is "s390x", similar to how it is handled in various toolchain components.

2025-02-12selftests/nolibc: split up architecture list in run-tests.shThomas Weißschuh
The list is getting overly long and any modifications introduce a lot of noise and are prone to conflicts. Split the string into a bash array and break that into multiple lines.

2025-02-03selftests/nolibc: always keep test kernel configuration up to dateThomas Weißschuh
Avoid using a stale test kernel configuration by always synchronizing it to the current source tree. kbuild is smart enough to avoid spurious rebuilds. Shuffle the code around a bit to keep all the commands with side-effects together.

2025-01-13selftests/nolibc: rename riscv to riscv64Thomas Weißschuh

2025-01-08selftests/nolibc: run-tests.sh: detect missing toolchainWilly Tarreau
The script tries to resolve the path to the current toolchain using realpath, which fails in case it's not installed, and since it's run under -e, it doesn't have the opportunity to display a help message. Let's detect the absence of the required toolchain before running that command and provide a friendlier message when this happens.
