selftests/nolibc: remove outdated comment about construct order

2025-09-01T18:48:41Z

The constructor order is not (and should not) be tested. Remove the comment. Fixes: a782d45c867c ("selftests/nolibc: stop testing constructor order") Signed-off-by: Benjamin Berg Link: https://lore.kernel.org/r/20250731201225.323254-3-benjamin@sipsolutions.net Signed-off-by: Thomas Weißschuh

selftests/nolibc: fix EXPECT_NZ macro

2025-09-01T18:48:41Z

The expect non-zero macro was incorrect and never used. Fix its definition.

selftests/nolibc: always compile the kernel with GCC

2025-08-18T14:05:41Z

LLVM/clang can not build the kernel for all architectures supported by nolibc. The current setup uses the same compiler to build the kernel as is used for nolibc-test. This prevents using the full qemu-system tests for LLVM builds. Instead always build the kernel with GCC. For the nolibc testsuite the kernel does not need to be built with LLVM.

selftests/nolibc: don't pass CC to toplevel Makefile

2025-08-18T14:05:40Z

The toplevel Makefile is capable of calculating CC from CROSS_COMPILE and/or ARCH. Stop passing the unnecessary variable. Signed-off-by: Thomas Weißschuh Acked-by: Willy Tarreau Link: https://lore.kernel.org/r/20250719-nolibc-llvm-system-v1-2-1730216ce171@weissschuh.net

selftests/nolibc: deduplicate invocations of toplevel Makefile

2025-08-18T14:05:40Z

Various targets of the testsuite call back into the toplevel kernel Makefile. These calls use various parameters and are quite long. Introduce a common variable to make future changes smaller and the lines shorter.

selftests/nolibc: be more specific about variables affecting nolibc-test

2025-08-18T14:05:39Z

Only one of these variables is used. $CC is preferred over $CROSS_COMPILE. Make this clear in the help message. Suggested-by: Willy Tarreau Link: https://lore.kernel.org/lkml/20250817093905.GA14213@1wt.eu/ Signed-off-by: Thomas Weißschuh

tools/nolibc: fix error return value of clock_nanosleep()

2025-08-17T09:42:09Z

clock_nanosleep() returns a positive error value. Unlike other libc functions it *does not* return -1 nor set errno. Fix the return value and also adapt nanosleep(). Fixes: 7c02bc4088af ("tools/nolibc: add support for clock_nanosleep() and nanosleep()") Signed-off-by: Thomas Weißschuh Acked-by: Willy Tarreau Link: https://lore.kernel.org/r/20250731-nolibc-clock_nanosleep-ret-v1-1-9e4af7855e61@linutronix.de Signed-off-by: Thomas Weißschuh

selftests/nolibc: add x32 test configuration

2025-07-13T14:58:41Z

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.

selftests/nolibc: show failed run if test process crashes

2025-07-09T16:28:36Z

The logic would not catch if the test process crashes and would incorrectly report a "success" state. Fix this by looking for the final "Total number of errors:" message and printing "failure" if it was not seen.

tools/nolibc: drop s390 clang target override

2025-07-08T07:24:00Z

tools/scripts/Makefile.include now has the same override, removing the need for the one in the nolibc Makefile. Drop the superfluous custom override.
